# D.A.W.N. — Your Own Personal, Private AI Assistant

**D.A.W.N.** is the central intelligence layer of [The OASIS Project](https://github.com/The-OASIS-Project) — an open-source voice-controlled AI assistant built for embedded Linux hardware. Think JARVIS from *Iron Man*, but real: an always-listening, conversational AI that controls your smart home, answers questions, searches the web, plays music, and more — running on hardware you own.

DAWN was designed from the ground up to be the closest thing to a production-quality JARVIS that actually exists. It listens for a wake word, understands natural speech, reasons about your request, and responds in a natural voice — all in real time. It remembers you — your preferences, your routines, the people and things you care about — and gets better the more you use it. It can run entirely offline with a local LLM, or connect to cloud providers like OpenAI, Claude, and Gemini. Multi-room satellite devices bring voice control to every room in your home, just like having JARVIS in every room of 10880 Malibu Point.

Unlike cloud-dependent assistants and plugin-based AI agents, DAWN runs entirely on your hardware. There is no extension marketplace, no third-party plugins, no arbitrary code execution. Every tool is compiled into the binary and audited at the source level. It can run fully offline — your voice, your data, your network, never leaving your home.

DAWN runs on platforms from a Jetson Orin to a Raspberry Pi 5 and supports multiple interfaces: a local microphone, a browser-based Web UI with voice and text input, and DAP2 satellite devices (Raspberry Pi or ESP32).

## Part of The OASIS Project

DAWN is one of seven components in **[The OASIS Project](https://github.com/The-OASIS-Project)** — an open-source effort to build a real, working Iron Man suit ecosystem. Each component is its own repo and works independently, but together they form a fully integrated system. DAWN is the brain; the others are the body.

DAWN itself is the closest thing to a real **JARVIS or FRIDAY** that exists today. A natural-voice assistant that listens, reasons across conversations, calls tools, controls the rest of the suit, and remembers you across sessions — your routines, the people you care about, the things you ask for again and again. 20+ built-in tools (calendar, email, smart home, music, search, memory, vision, more). Multi-room satellites put her in every room of the house. Cloud LLM or fully local; you pick.

The sibling components:

| Component | Role | Repo |
|---|---|---|
| **MIRAGE** | Heads-up display — dual micro-displays, switchable HUD screens, live video | [mirage](https://github.com/The-OASIS-Project/mirage) |
| **STAT** | Telemetry daemon — battery, power, system metrics, fault detection | [stat](https://github.com/The-OASIS-Project/stat) |
| **ECHO** | Cellular daemon — routes phone calls and SMS into DAWN (SIM7600G-H modem) | [echo](https://github.com/The-OASIS-Project/echo) |
| **AURA** | Helmet sensors — IMU, GPS, air quality, temperature, servo faceplate (ESP32-S3, FreeRTOS) | [aura](https://github.com/The-OASIS-Project/aura) |
| **SPARK** | Hand firmware — gesture detection, repulsor LED animations, wireless | [spark](https://github.com/The-OASIS-Project/spark) |
| **BEACON** | 3D-printable parts library — enclosures, mounts, chassis | [beacon](https://github.com/The-OASIS-Project/beacon) |

Everything is GPLv3. Cloud LLMs are optional — DAWN runs fully local if you want it to.

## Features

### Voice Intelligence

- **Speech Recognition** — Whisper ASR with GPU acceleration on Jetson (2.3x–5.5x faster than real-time). Intelligent voice activity detection knows when you're speaking and when you've stopped.
- **Multi-Provider LLM** — Cloud: OpenAI GPT-5, Anthropic Claude 4.6, Google Gemini 2.5/3, or any model through the OpenRouter gateway. Local: llama.cpp or Ollama for fully offline operation. Runtime model switching via WebUI or voice.
- **Text-to-Speech** — Piper TTS with ONNX Runtime. Multiple voices included. Text preprocessing for natural phrasing.
- **Speech-Shaped Replies** — On voice interfaces (satellites, local mic, WebUI voice) DAWN tells the model its reply will be read aloud, so answers stay concise and skip on-screen-only formatting; it also warns the model that speech-transcribed input may contain homophone mishearings to interpret from context. All three directives are editable in Settings (Text-to-Speech / Speech Recognition), and the WebUI voice variant keeps the screen free for visuals.
- **Extended Thinking** — Deep reasoning mode for complex queries:
   - Claude: thinking budget control with collapsible blocks
   - OpenAI: reasoning effort (low/medium/high) for o1/o3/o4 models
   - Gemini: thinking mode for Gemini 2.5 Flash/Pro
   - Local: Qwen3 thinking mode with native template support
- **Cloud Rate Limiting** — Built-in throttling prevents you from getting rate-limited by cloud providers.
- **Streaming Responses** — DAWN starts speaking while still thinking, just like a real conversation. Perceived latency drops to ~1.3 seconds.

### Multi-Room Voice (DAP2 Satellites)

- **One Server, One Port, Three Client Types** — The WebUI server on port 3000 is the single entry point for browsers, Raspberry Pi satellites, and ESP32 satellites. No extra servers or ports required.
- **Tier 1 (Raspberry Pi)** — Local ASR/TTS, hands-free with wake word. Sends only text to the server. SDL2 touchscreen UI with KMSDRM backend.
- **Tier 2 (ESP32-S3)** — Streams raw PCM audio; server handles ASR/TTS. Push-to-talk operation.
- **Music Streaming** — Stream music to every room through your Tier 1 satellites.
- **No Double Answers** — When your local microphone and a nearby satellite both hear the same command, DAWN recognizes the duplicate and only one of them responds. Configurable dedup window under `[asr]`.
- **Over-the-Air Updates** — Push signed firmware and software updates from the daemon to your satellites without touching each device — Tier 1 (Raspberry Pi) and Tier 2 (ESP32-S3) both supported. Releases are signed offline (the daemon never holds the signing key) and verified against a baked-in public key on the device. Roll out to one device or the whole fleet from the WebUI admin panel or the `dawn-admin ota` CLI, with per-device version tracking and anti-rollback protection.
- **Easy Pairing** — Provision a new satellite by scanning a QR code from the WebUI admin panel — no manual token copying.

### Web Interface

- **Browser-Based** — Accessible on port 3000 from any device on your network.
- **Voice & Text Input** — Three input modes via unified action button: Send Text, Hold to Talk (push-to-talk), and Continuous Listening (always-on wake word detection with server-side VAD). Smart typing override temporarily switches voice modes to Send when text is present.
- **Real-Time Communication** — WebSocket-based with session persistence across page refreshes (30-minute timeout).
- **Settings Panel** — Live configuration editing from the browser. API keys with secure handling. Restart indicators for settings that require it.
- **User Management** — Cookie-based authentication with "Remember Me" (30-day sessions). Admin tools: create/delete users, reset passwords, unlock accounts. Per-user persona, location, timezone, units, and TTS speed preferences.
- **Conversation History** — Browse, search, continue, delete, and export (JSON/HTML) past conversations. One-click message copy. Per-conversation LLM settings (reasoning mode, tools mode).
- **7 Color Themes** — Cyan, Purple, Green, Orange, Red, Blue, and Terminal.
- **Vision & Documents** — Send images for AI analysis (upload, paste, drag-and-drop, camera capture). Attach text documents (Markdown, CSV, JSON, source code, and more) for LLM context.
- **Accessibility** — Keyboard navigation, screen reader support (ARIA), reduced motion preferences, WCAG-compliant touch targets. Mobile-friendly responsive design.
- **Debug Mode** — Toggle to view tool results, commands, and system messages.

### Messaging Channels (Chat Apps & SMS)

- **Talk to DAWN from the apps you already use** — Link a **Telegram**, **Slack**, **Discord**, or **SMS** conversation to your account and get the full assistant (tools, memory, scheduler) from your phone or desktop chat client, no WebUI required.
- **One-time link flow** — Generate a link code in the WebUI or via `dawn-admin`, send `/link CODE` from the chat app, and you're connected. Drivers load only when their token is configured.
- **Forever-conversations** — Each channel maps to one persistent conversation that shows up in WebUI history and feeds memory extraction like any other session. `/new` resets the thread.
- **Scheduler delivery** — Briefings, reminders, and alarms can be delivered to a messaging channel instead of spoken aloud — "send me a morning briefing on Telegram."
- **Read & summarize Discord channels** — Ask DAWN to catch you up on a server channel ("summarize the dev-chat channel from this morning") or a whole server at once. Read-only and pull-based — the bot reads history only on request or for a scheduled digest, never posts on its own.
- **Channel management** — Rename, unlink (history preserved), and re-enable channels from the WebUI panel or the `dawn-admin messaging` operator commands.
- **Setup**: [docs/MESSAGING_CHANNELS_SETUP.md](docs/MESSAGING_CHANNELS_SETUP.md).

### Phone Calls & SMS

DAWN routes cellular calls and text messages through the **[ECHO](https://github.com/The-OASIS-Project/echo)** daemon (SIM7600G-H modem), so your assistant lives on a real phone number.

- **SMS by voice** — "Text Bob that I'm running late." Send and receive texts with two-step confirmation, recipient resolution against your contacts, and a searchable message history.
- **Incoming-call handling** — When a call comes in, DAWN announces it, rings on the local speaker, shows a HUD notification, and pops an **incoming-call banner in the WebUI** with the caller's name and photo (resolved from contacts).
- **Answer from anywhere** — Accept, reject, or hang up a call by voice ("Friday, answer") or from the browser banner. A persistent in-call panel shows live call duration and rehydrates after a page reload.
- **Call & SMS history** — Every call and message is logged to a per-user database with configurable retention.

> **Note:** Two-way call *audio* through the browser is still in progress — today calls ring, announce, and can be answered/controlled, and SMS is fully functional. Setup lives in [docs/PHONE_SMS_DESIGN.md](docs/PHONE_SMS_DESIGN.md) and the [ECHO repo](https://github.com/The-OASIS-Project/echo).

### Smart Home & IoT

- **Home Assistant** — Control lights (on/off/brightness/color/color temperature), climate, locks, covers, media players. Activate scenes, trigger scripts and automations. Entity status queries with area-aware responses.
- **Fuzzy Name Matching** — "Turn on the living room light" works even if the entity is named slightly differently.
- **MQTT Device Control** — Extensible device callback architecture for integration with other OASIS components or external systems.

### LLM Tools

DAWN's LLM automatically invokes tools and incorporates results into responses. Multiple tool calls execute concurrently for faster answers.

- **Web Search** — Voice-activated search via SearXNG (self-hosted, privacy-focused) or optional [Tavily](https://tavily.com) (commercial, LLM-optimized; free tier 1000 calls/month). Categories: web, news, social, science, IT, Q&A, dictionary, academic papers. Time filtering for recent results (today, this week, this month).
- **Image Search** — Search and display images from the web. Images are fetched server-side (SSRF-protected with DNS pinning), cached locally, and served via zero-copy file serving. Click-to-enlarge lightbox in WebUI. Results displayed as inline markdown images.
- **URL Fetcher** — Fetch and read web pages. Optional FlareSolverr (headless browser) or Tavily `/extract` (commercial, LLM-optimized) fallback for JavaScript-heavy sites. SSRF-protected. Untrusted-content framing on tool results.
- **Weather** — Real-time weather and forecasts via Open-Meteo API (free, no API key required).
- **Calculator** — Expression evaluation (`+ - * / ^`, `sqrt`, trig, `factorial`) plus a digit-perfect **exact mode** for arbitrary-precision integer results — every digit of `52!` or `2^256`, no scientific-notation rounding. Also unit conversion, base conversion, and random numbers.
- **CalDAV Calendar** — CalDAV calendar integration (Google Calendar via OAuth 2.0, iCloud, Nextcloud, Radicale). Query today's events, search by keyword, add/update/delete events across multiple accounts. Filter queries by calendar name.
- **Email** — Multi-account IMAP/SMTP email (Gmail via OAuth 2.0, iCloud, Outlook, Fastmail, self-hosted). Check inbox, read messages, search, send with two-step confirmation, trash with confirmation, archive. Pagination for large result sets. Per-account read-only flag. Contacts system for recipient resolution.
- **Scheduler** — Timers, alarms, reminders, and scheduled tool execution.
   - "Set a 10 minute timer", "Wake me up at 7 AM", "Remind me to call Mom at 3pm"
   - Recurring events (daily, weekdays, weekends, weekly, custom days)
   - Audible chimes with configurable volume, snooze, and dismiss via voice or WebUI
   - Scheduled tasks: "Turn off the lights at midnight" (executes any registered tool)
- **Sound Effects** — Play sound effects from the OASIS armor system (SPARK repulsor → AURA → MIRAGE → DAWN). Concurrent playback (4 slots), path traversal protection, configurable sound directory.
- **Multi-Step Plans** — Complex workflows execute locally in a single LLM round trip. The plan executor interprets a JSON DSL with conditional logic, loops, and variable binding — "If I don't have any alarms, set one for 7am" runs as one plan instead of multiple back-and-forth tool calls.
- **Visual Diagrams** — The LLM generates inline SVG/HTML visuals to explain concepts. Flowcharts, architecture diagrams, data charts (Chart.js), interactive widgets, UI mockups, and illustrations render directly in the conversation with clickable nodes for drill-down. Visuals persist across page refresh and render inline within the message text. Design guidelines loaded on demand via the two-step instruction pattern keep the system prompt lightweight. Download button for SVG/HTML export.
- **Document Search (RAG)** — Upload documents and ask questions about their content.
   - Semantic search across uploaded PDFs, DOCX, TXT, and Markdown files
   - Literal-text search (`document_grep`) — find an exact string with the matched line plus surrounding context, for precise lookups where meaning-based search is too fuzzy
   - Structure-aware chunking for YAML and CSV (one record per chunk) keeps record lookups precise
   - Paginated document reading for full-document summaries
   - Hybrid scoring: vector cosine similarity + keyword boosting
   - Original uploads retained and downloadable alongside the extracted text, with configurable per-user retention caps under `[documents]`
   - Per-user document isolation with admin-controlled global sharing
   - WebUI Document Library panel with drag-and-drop upload and admin document management
- **Notes & Reference Text** — Ask DAWN to file notes and reference text it can search and recall later ("save this as my public bio", "what's on my packing list?").
   - Hybrid keyword search tuned for short, named notes (built on the same Document Search store)
   - Surgical edits: append to or replace part of a note without re-saving the whole thing
   - Version history with one-step undo — recover the previous version or restore a deleted note
   - Filed reference text is kept out of semantic memory by default, so the canonical copy lives only in the note store (configurable under `[memory]`)
- **Code Projects (Code Analysis)** — Index your source repositories into a code graph and ask about them by voice or chat: "what calls `parse_payload`?", "where is the session manager defined?", "what changed on this branch?". Import a GitHub-style repo (in-process libgit2 clone) or link a local checkout; per-project branch tracking and refresh/rebuild. Answering runs against an **external, operator-launched** code-graph server (**cbm**) — DAWN connects to it over MCP and never spawns it. Optional; requires the cbm server plus the coding-harness build flags. Setup: [docs/CODING_PROJECTS.md](docs/CODING_PROJECTS.md).
- **Suit & System Telemetry** — Ask about the live state of the armor and the machine DAWN runs on: environment (temperature, humidity, air quality, CO₂), helmet orientation (heading/pitch/roll), GPS position, and per-piece armor status via `suit_status`; CPU, memory, battery, power, thermals, and fault counts via `system_status`. Fed over MQTT from the AURA helmet + SPARK armor (through MIRAGE) and the STAT daemon; values age out and report staleness when a source goes quiet rather than returning stale guesses.

### Persistent Memory

DAWN remembers facts, preferences, and relationships about its users across sessions — and forgets them on request.

- **Memory Tool** — "Remember that I'm vegetarian", "What do you know about me?"
- **Hybrid Search** — Finds the right memory whether you use the exact words or just describe what you're looking for. Keyword and meaning-based search working together.
- **Entity Graph** — Automatically learns the people, places, pets, and projects in your life and how they relate to each other.
- **Automated Extraction** — Facts, preferences, entities, and relations extracted at session end.
- **Crash-Resilient Extraction** — Conversations interrupted by a daemon crash mid-extraction are picked up by a background recovery worker, configurable under `[memory.recovery]`.
- **Privacy Toggle** — Mark conversations as private to prevent memory extraction (Ctrl+Shift+P in WebUI).
- **Confidence Decay** — Unused memories naturally fade; accessed memories are reinforced.
- **Contacts** — Store email addresses, phone numbers, and addresses for people DAWN knows. Upload contact photos (compressed and circular-cropped in the WebUI) that appear as thumbnails in the contact list and are sent as base64 in HUD notifications for incoming calls and SMS. Linked to the entity graph. Used by the email and phone systems for contact resolution. Managed via voice ("Save Bob's email") or the WebUI Contacts tab.
- **Entity Merge** — Combine duplicate entities ("Dawn" + "Dawn Smith"), transferring all relations and contacts. Available via voice or WebUI.
- **Memory Viewer** — Browse, search, and manage all memory types in the WebUI. Five tabs: Facts, Preferences, Summaries, Graph, Contacts.
- **Import / Export** — Export memories as DAWN JSON (lossless backup) or human-readable text (portable). Import from Claude, ChatGPT, or other AIs — paste text or upload a file. Preview before committing with automatic duplicate detection.
- **Per-User Isolation** — Each user's memory is separate in multi-user households.

### Proactive Attention

DAWN doesn't just answer — it watches, and speaks up on its own. Tell it what to keep an eye on, in plain language, and it flags anomalies without being asked.

- **Set watches by voice** — "Keep an eye on the CO₂", "Tell me if the battery drops below 20%", "Let me know if system temp goes above 70°C", "Alert me if the helmet link goes quiet". Watches are per-user and managed conversationally — "What are you watching?", "Ignore that temperature for now", "Stop watching the CPU".
- **~24 watchable signals** across the suit (CO₂, air quality, heat index, helmet/armor temperature, armor voltage, telemetry-silence) and the compute unit (CPU, memory, battery level/voltage/runtime, thermals, critical/warning faults).
- **Smart, not noisy** — a deterministic gate with threshold/slope/absence rules, hysteresis, and exponential backoff means one alert per genuine excursion, not a stream: it fires when a value crosses the line, stays quiet while it's out, and re-arms once it recovers. A per-hour budget caps spoken interruptions.
- **Two loudness levels** — spoken **ATTENTION** alerts (voice + banner) for the things you want to hear, or silent banners for the things you just want on the HUD. Your wording picks which.
- **Off by default** — opt in with `[attention] enabled = true` (or the WebUI Settings toggle). Alerts are delivered chime-free off the audio path so they never stall the voice loop.

### Music Playback

- **Multi-Format** — FLAC, MP3, and Ogg Vorbis with auto-format detection and mixed-format playlists.
- **Local + Plex Unified Library** — Local files and Plex Media Server tracks in a single searchable library. Duplicates automatically merged. Search by artist, title, album, or genre.
- **LLM Playlist Builder** — AI can search, add, remove, and clear queue tracks by voice. Genre-aware search.
- **Resume Playback** — Pause saves position, resume continues where you left off.
- **Opus Streaming** — Stream music to WebUI and DAP2 satellites via WebSocket.
- **Media Key Controls** — Hardware media keys and lock-screen/OS media controls play, pause, and skip DAWN's music, with track metadata shown in the OS now-playing UI.

## Hardware Recommendations

DAWN runs on a range of hardware. These tables can help you choose the right platform.

> **Runtime memory:** the daemon's resident set is roughly **~1.6 GB** on a Jetson with GPU-accelerated Whisper and a cloud LLM — most of it the CUDA runtime, not the models. A local LLM adds its model size on top (commonly +2–8 GB). See [ARCHITECTURE.md — Memory Management](ARCHITECTURE.md#memory-management) for the full breakdown.

### Server Hardware (runs the DAWN daemon)

#### Tier 1: Excellent (Production Ready)

| Platform | Price | AI Performance | Notes |
|----------|-------|----------------|-------|
| **Jetson Orin Nano Super** | ~$249 | 67 TOPS | Primary target. GPU Whisper ~0.1s RTF |
| **Jetson Orin NX** | ~$1,000 | 100 TOPS | Excellent headroom for all features |
| **Jetson AGX Orin 64GB** | ~$2,000 | 275 TOPS | Best for running large local LLMs alongside DAWN |

#### Tier 2: Good (Usable with minor tradeoffs)

| Platform | Price | AI Performance | Notes |
|----------|-------|----------------|-------|
| **Raspberry Pi 5 (8GB)** | ~$125 | CPU-only, ~1.0 RTF | Whisper base: ~6s for 10s audio |
| **Raspberry Pi 5 + AI Kit** | ~$200 | 13 TOPS | Hailo-8L helps vision, not ASR |

#### Tier 3: Not Recommended for Server

| Platform | Issue |
|----------|-------|
| **Raspberry Pi 4** | May work as a satellite, too slow for server use |
| **Raspberry Pi 3 / Zero 2** | Too slow, insufficient RAM |
| **32-bit ARM systems** | Limited memory, slow inference |

### Recommendations by Use Case

| Use Case | Recommended Platform | Why |
|----------|---------------------|-----|
| **Cost-conscious hobbyist** | Raspberry Pi 5 (8GB) ~$125 | Works with Whisper tiny/base, acceptable latency |
| **Best value** | Jetson Orin Nano Super ~$249 | GPU acceleration, real-time voice AI |
| **Production / commercial** | Jetson AGX Orin 32GB/64GB | Run 7B–13B local LLMs alongside the full voice pipeline |
