# FocusWith

**A private-by-default focus system that helps turn meaningful plans into finished work.**

FocusWith turns vague goals into directions, projects, tasks, and focused sessions. It keeps the core loop simple: choose one thing, start, return when distracted, finish, and decide what comes next.

It works without Telegram and without an AI key. The core is a self-hosted web app; optional adapters add an AI companion, MCP connections, Telegram buttons, iPhone Shortcut events, an Android usage/timer companion, and native floating timers for macOS and experimental Windows testing.

The web interface automatically follows Chinese browsers and can be switched between Simplified Chinese and English at any time. The choice is stored only in that browser.

> **Public preview:** FocusWith is currently a single-owner `0.x` project. Back up your data before upgrading and review AI tool actions before approving them.

## Why FocusWith

- **Private by default.** Local installs bind to `127.0.0.1`; public MCP is opt-in and OAuth-protected.
- **Plans become something you can do.** Organize directions → projects → tasks, or paste a Markdown plan generated by an AI chat.
- **The loop does not stop at a timer.** FocusWith records sessions, merges repeated work on the same task, carries unfinished work forward, and recommends the next action.
- **Earned rewards stay earned.** Choose or create a reward, build an uninterrupted focus streak toward it, and redeem it later from a persistent reward cabinet.
- **AI is optional, not the owner.** Use the app alone, add a provider, or connect an existing Claude/Codex-compatible client through MCP.
- **Distraction reminders have context.** Phone events can be linked to the active session, with grace periods, strikes, reminders, and user-defined consequences.

## What works

- Directions, projects, actionable tasks, and manual project assignment.
- Simplified Chinese and English interfaces with automatic browser-language detection and a persistent language switch.
- Markdown plan import with duration parsing and break recognition.
- Pomodoro, deep-focus, free-focus, and count-up sessions with custom durations.
- Pause, resume, finish, cancel, complete, and abandon flows.
- Daily and weekly statistics; repeated sessions for one task are merged into one activity total.
- Editable monitored-app policy, grace period, strike count, and consequence pool.
- Browser notifications and optional Telegram delivery with action buttons.
- iPhone Shortcut event ingestion and daily app-usage summaries.
- Android usage-event sync with a persistent timer notification and an optional floating capsule.
- Editable uninterrupted-focus rewards with a default example, selectable targets, persistent earned inventory, and automatic camera/blocklist/timer evidence fallback.
- Built-in companion using OpenAI Responses, Anthropic, or an OpenAI-compatible API, including compatible local endpoints.
- Eleven annotated MCP tools for Claude Desktop/Code, Codex, and other local clients, including reward progress and redemption.
- Optional OAuth-protected Remote MCP for Claude.ai and compatible ChatGPT workspaces, with automated clean-VPS HTTPS deployment.
- Native macOS floating timer with an opt-in, local-only camera companion; full Xcode is not required.
- Experimental Windows WinUI 3 floating timer with local ONNX phone detection; CI-built, pending physical camera validation.
- Local installer and Docker Compose deployment.

## Fastest installation

Give this repository to a coding agent and ask it to install FocusWith. The exact prompt and safety contract are in [docs/AI_INSTALL.md](docs/AI_INSTALL.md) and [AGENTS.md](AGENTS.md).

Manual installation requires Python 3.11 or newer:

```bash
./scripts/install.sh
./scripts/focus start
```

Open `http://127.0.0.1:8765`. On localhost, the browser connects without asking you to copy the generated API token.

Useful commands:

```bash
./scripts/focus status
./scripts/focus doctor
./scripts/focus logs
./scripts/focus stop
```

## Optional AI and MCP

For the built-in companion, edit the ignored `.env` file and restart FocusWith. The complete provider recipes are in [docs/AI_PROVIDERS.md](docs/AI_PROVIDERS.md).

```dotenv
FOCUS_AI_PROVIDER=anthropic
FOCUS_AI_API_KEY=your-provider-key
FOCUS_AI_MODEL=your-model-name
```

For DeepSeek, GLM, a local model, or another compatible service:

```dotenv
FOCUS_AI_PROVIDER=openai-compatible
FOCUS_AI_API_KEY=your-provider-key
FOCUS_AI_MODEL=your-model-name
FOCUS_AI_BASE_URL=https://provider.example/v1
```

Provider keys stay on the server and are never sent to browser JavaScript.

To use an existing AI client, connect the private local server in [docs/MCP.md](docs/MCP.md). Claude.ai and eligible ChatGPT workspaces can use the authenticated Remote MCP in [docs/REMOTE_MCP.md](docs/REMOTE_MCP.md). Remote mode uses HTTPS, OAuth discovery, Dynamic Client Registration, S256 PKCE, rotating refresh tokens, strict callback allowlisting, and revocation; it is disabled by default.

## Optional integrations

- macOS floating timer: `./macos/FocusFloat/install.sh`
- Windows floating timer preview: [windows/FocusFloat/README.md](windows/FocusFloat/README.md)
- Camera companion and cross-platform event contract: [docs/CAMERA_COMPANION.md](docs/CAMERA_COMPANION.md)
- Uninterrupted-focus rewards: [docs/REWARDS.md](docs/REWARDS.md)
- iPhone Shortcuts: [docs/IPHONE_SHORTCUTS.md](docs/IPHONE_SHORTCUTS.md)
- Android companion: [docs/ANDROID.md](docs/ANDROID.md)
- Signed Android and experimental Windows downloads: [GitHub Releases](https://github.com/sayhi2e10414-cpu/focus-with/releases)
- Telegram: set `FOCUS_TELEGRAM_BOT_TOKEN` and `FOCUS_TELEGRAM_CHAT_ID` in `.env`, then restart.

Telegram is a delivery adapter, not the owner of the Focus session. Timer completion and distraction events are created by FocusWith, then delivered to the browser and any enabled channel.

## Docker and Remote MCP

Local Docker deployment:

```bash
./scripts/setup_env.py
docker compose up -d --build
```

Compose publishes only to `127.0.0.1:8765` by default and stores the database in a named volume.

For a dedicated public hostname and Claude.ai connector on a clean Docker VPS:

```bash
./scripts/deploy_remote.sh --domain focus.example.com
```

The script refuses to replace an existing service on ports 80/443. See [docs/REMOTE_MCP.md](docs/REMOTE_MCP.md) for prerequisites, the existing-proxy mode, Claude connection steps, password rotation, and revocation commands.

## Security

- The default server bind is `127.0.0.1`.
- Separate random tokens protect the main API and phone-event endpoint.
- Runtime data, `.env`, logs, generated apps, and databases are ignored by Git.
- API/provider tokens are not embedded in JavaScript, documentation, MCP configuration, or the macOS bundle.
- Camera frames stay inside the companion app. Distraction events contain only an ID, sustained duration, timestamp, and source; reward heartbeats contain only timestamp, source, and camera state. Image-derived fields are rejected.
- Remote MCP cannot run with only half of its OAuth configuration.
- Remote MCP uses a salted owner-password hash, strict callback allowlisting, PKCE, scoped audience-bound bearer tokens, rotation, and revocation.
- OAuth bearer tokens, refresh tokens, authorization codes, login tickets, and CSRF artifacts are stored only as hashes.

Read [SECURITY.md](SECURITY.md) before exposing FocusWith outside localhost.

## Development

```bash
python3.12 -m venv .venv
.venv/bin/pip install -r requirements-dev.txt
.venv/bin/pytest -q
./macos/FocusFloat/test.sh
```
