```bash
pip install mengram-ai   # or: npm install mengram-ai

mengram try              # see what memory would know about you — local only,
                         # no account, nothing leaves your machine
```

```python
from mengram import Mengram
m = Mengram(api_key="om-...")           # Free key → mengram.io

m.add([{"role": "user", "content": "I use Python and deploy to Railway"}])
m.search("tech stack")                  # → facts
m.ask("what's my tech stack?")          # → synthesized answer + citations
m.episodes(query="deployment")          # → events
m.procedures(query="deploy")            # → workflows that evolve from failures
```

Native multilingual: ask in Russian, Chinese, Spanish, Japanese — Mengram retrieves and answers across 23 languages (Cohere multilingual embeddings + rerank).

## Install in one prompt (any AI tool)

Paste this into Claude Desktop, Cursor, Codex, Claude Code, or Windsurf — the agent reads our [setup guide](https://mengram.io/agent-install.txt), installs the SDK, configures the MCP server, and verifies the round-trip end-to-end. **No terminal context-switching.**

```
Install Mengram for me. Fetch the canonical install guide at
https://mengram.io/agent-install.txt and follow it precisely.
My email is YOUR_EMAIL_HERE.
```

Works in any agent with shell + file-edit + web-fetch tools. Prefer doing it manually? See the [plain-text guide](https://mengram.io/agent-install.txt) — it's structured for human eyes too.

## Claude Code — Memory That Survives /clear AND Auto-Compaction

Persistent memory that survives `/clear`, **auto-compaction**, machine switches, and team handoffs — the SessionStart hook fires after every compact and re-injects your context. The summary can be lossy; the memory isn't.

```bash
# 1. Get a free key at https://mengram.io and save it once
mkdir -p ~/.mengram && echo '{"api_key": "om-your-key-here"}' > ~/.mengram/config.json

# 2. Install the plugin (hooks + MCP server + skill)
claude plugin marketplace add alibaizhanov/mengram
claude plugin install mengram@mengram

# 3. Skip the cold start — import your existing session history
#    (secrets are redacted on your machine before anything is uploaded)
mengram import claude-code
```

What happens:

```
Session Start  →  Loads your cognitive profile (fires after /clear, compaction, and restarts)
Every Prompt   →  Searches past sessions for relevant context (auto-recall)
After Response →  Saves new knowledge in background (auto-save)
```

No manual saves. No tool calls. Claude just knows what you worked on yesterday — even after compaction ate the transcript.

Prefer CLI-managed hooks instead of the plugin? `pip install mengram-ai && mengram setup` does the same via `mengram hook install`.

## Why Mengram?

Every AI memory tool stores facts. Mengram stores **3 types of memory** — and procedures **evolve when they fail**.

|  | Mengram | claude-mem | Mem0 | Zep | Letta |
|---|:---:|:---:|:---:|:---:|:---:|
| Semantic memory (facts, preferences) | **Yes** | Yes | Yes | Yes | Yes |
| **Episodic memory (events, decisions)** | **Yes** | Partial | No | No | Partial |
| **Procedural memory (workflows)** | **Yes** | No | No | No | No |
| **Procedures evolve from failures** | **Yes** | No | No | No | No |
| **Cognitive Profile** | **Yes** | No | No | No | No |
| **Native multilingual retrieval (23 languages)** | **Yes** | Partial | No | No | No |
| **Ask & Citations (synthesized answer)** | **Yes** | No | No | No | No |
| Multi-user isolation | **Yes** | No | Yes | Yes | No |
| Knowledge graph | **Yes** | No | Yes | Yes | Yes |
| Claude Code hooks (auto-save/recall) | **Yes** | **Yes** | No | No | No |
| MCP server | **Yes** | Yes | Yes | Yes | Yes |
| LangChain + CrewAI integrations | **Yes** | No | Partial | Partial | Partial |
| **Import Claude Code history / ChatGPT / Obsidian** | **Yes** | No | No | No | No |
| Pricing | **Free tier** | Free OSS (+cloud backup) | $19-249/mo | Enterprise | Self-host |

## Get Started in 30 Seconds

**1. Install**

```bash
pip install mengram-ai
```

**2. Setup** — one command does everything: account, Claude Code hooks, MCP configs for detected tools (Cursor, Claude Desktop, Windsurf), history import, and a round-trip check

```bash
mengram setup
```

Or get a key manually at [mengram.io](https://mengram.io/#signup) and `export MENGRAM_API_KEY=om-...`

**3. Use**

```python
from mengram import Mengram

m = Mengram(api_key="om-...")

# Add a conversation — auto-extracts facts, events, and workflows
m.add([
    {"role": "user", "content": "Deployed to Railway today. Build passed but forgot migrations — DB crashed. Fixed by adding a pre-deploy check."},
])

# Search across all 3 memory types at once
results = m.search_all("deployment issues")
# → {semantic: [...], episodic: [...], procedural: [...]}
```

<details>
<summary><b>File Upload (PDF, DOCX, TXT, MD)</b></summary>

```python
# Upload a PDF — auto-extracts memories using vision AI
result = m.add_file("meeting-notes.pdf")
# → {"status": "accepted", "job_id": "job-...", "page_count": 12}

# Poll for completion
m.job_status(result["job_id"])
```

```javascript
// Node.js — pass a file path
await m.addFile('./report.pdf');

// Browser — pass a File object from <input type="file">
await m.addFile(fileInput.files[0]);
```

```bash
# REST API
curl -X POST https://mengram.io/v1/add_file \
  -H "Authorization: Bearer om-..." \
  -F "file=@meeting-notes.pdf" \
  -F "user_id=default"
```

</details>

<details>
<summary><b>JavaScript / TypeScript</b></summary>

```bash
npm install mengram-ai
```

```javascript
const { MengramClient } = require('mengram-ai');
const m = new MengramClient('om-...');

await m.add([{ role: 'user', content: 'Fixed OOM by adding Redis cache layer' }]);
const results = await m.searchAll('database issues');
// → { semantic: [...], episodic: [...], procedural: [...] }
```

</details>

```bash
# Add memory
curl -X POST https://mengram.io/v1/add \
  -H "Authorization: Bearer om-..." \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role": "user", "content": "I prefer dark mode and vim keybindings"}]}'

# Search all 3 types
curl -X POST https://mengram.io/v1/search/all \
  -H "Authorization: Bearer om-..." \
  -d '{"query": "user preferences"}'
```

</details>

## 3 Memory Types

### Semantic — facts, preferences, knowledge

```python
m.search("tech stack")
# → ["Uses Python 3.12", "Deploys to Railway", "PostgreSQL with pgvector"]
```

### Episodic — events, decisions, outcomes

```python
m.episodes(query="deployment")
# → [{summary: "DB crashed due to missing migrations", outcome: "resolved", date: "2025-05-12"}]
```

### Procedural — workflows that evolve

```
Week 1:  "Deploy" → build → push → deploy
                                         ↓ FAILURE: forgot migrations
Week 2:  "Deploy" v2 → build → run migrations → push → deploy
                                                          ↓ FAILURE: OOM
Week 3:  "Deploy" v3 → build → run migrations → check memory → push → deploy ✅
```

This happens **automatically** when you report failures:

```python
m.procedure_feedback(proc_id, success=False,
                     context="OOM error on step 3", failed_at_step=3)
# → Procedure evolves to v3 with new step added
```

Every failure-driven revision records **which assumption turned out false** — not just which step broke — and derives a precondition that travels with the procedure at recall time:

```json
{
  "version": 3,
  "violated_assumption": "the build container had enough memory for a full build",
  "preconditions": ["check available memory before building"],
  "success_count": 11, "fail_count": 2
}
```

An agent loading v3 doesn't repeat the two mistakes that produced it — and knows what to verify before trusting the workflow.

Or **fully automatic** — just add conversations and Mengram detects failures and evolves procedures:

```python
m.add([{"role": "user", "content": "Deploy failed again — OOM on the build step"}])
# → Episode created → linked to "Deploy" procedure → failure detected → v3 created
```

## Ask Your Memory (RAG built-in)

`m.ask()` returns a synthesized answer with citations — not a raw fact list.
Mengram embeds your query, retrieves the top relevant facts, and uses
Cohere Chat to write a grounded answer with native source attribution.

```python
result = m.ask("what programming languages do I use?")

print(result["answer"])
# 'You use Python and Rust. Python is your daily language [1] and
#  Rust is your favorite [2]. You also know Java for enterprise
#  systems [3].'

for cit in result["citations"]:
    print(f'  "{cit["text"]}" → {cit["sources"][0]["fact"]}')
# "Python and Rust" → uses Python daily for backend development
# "favorite [2]"   → Rust is favorite language
# "Java"           → specializes in Java/Spring Boot
```

Multilingual: ask in any of 23 languages, get an answer in the same language with citations linking back to facts in the original language they were stored. Premium feature (Pro / Growth / Business).

## Cognitive Profile

One API call generates a system prompt from all memories:

```python
profile = m.get_profile()
# → "You are talking to Ali, a developer in Almaty. Uses Python, PostgreSQL,
#    and Railway. Recently debugged pgvector deployment. Prefers direct
#    communication and practical next steps."
```

Insert into any LLM's system prompt for instant personalization.

## Import Existing Data

Kill the cold-start problem:

```bash
mengram import chatgpt ~/Downloads/chatgpt-export.zip --cloud   # ChatGPT history
mengram import obsidian ~/Documents/MyVault --cloud              # Obsidian vault
mengram import files notes/*.md --cloud                          # Any text/markdown
```

## Integrations

## Multi-User Isolation

One API key, many users — each sees only their own data:

```python
m.add([...], user_id="alice")
m.add([...], user_id="bob")

m.search_all("preferences", user_id="alice")  # Only Alice's memories
m.get_profile(user_id="alice")                 # Alice's cognitive profile
```

## Async Client

Non-blocking Python client built on httpx:

```python
from mengram import AsyncMengram

async with AsyncMengram() as m:
    await m.add([{"role": "user", "content": "I use async/await"}])
    results = await m.search("async")
    profile = await m.get_profile()
```

Install with `pip install mengram-ai[async]`.

## Metadata Filters

Filter search results by metadata:

```python
results = m.search("config", filters={"agent_id": "support-bot", "app_id": "prod"})
```

## Webhooks

Get notified when memories change:

```python
m.create_webhook(
    url="https://your-app.com/hook",
    event_types=["memory_add", "memory_update"],
)
```

## Agent Templates

Clone, set API key, run in 5 minutes:

| Template | Stack | What it shows |
|---|---|---|
| **[DevOps Agent](examples/devops-agent/)** | Python SDK | Procedures that evolve from deployment failures |
| **[Customer Support](examples/customer-support-agent/)** | CrewAI | Agent with 5 memory tools, remembers returning customers |
| **[Personal Assistant](examples/personal-assistant/)** | LangChain | Cognitive profile + auto-saving chat history |

```bash
cd examples/devops-agent && pip install -r requirements.txt
export MENGRAM_API_KEY=om-...
python main.py
```

## Use with AI Agents

Mengram works as a persistent memory backend for autonomous agents. Your agent stores what it learns, and recalls it on the next run — getting smarter over time.

```python
from mengram import Mengram

m = Mengram(api_key="om-...")

# Agent completes a task → store what happened
m.add([
    {"role": "user", "content": "Apply to Acme Corp on Greenhouse"},
    {"role": "assistant", "content": "Applied successfully. Had to use React Select workaround for dropdowns."},
])
# → Extracts: fact ("applied to Acme Corp"), episode ("Greenhouse application"),
#   procedure ("React Select dropdown workaround")

# Next run → agent recalls what worked before
context = m.search_all("Greenhouse application tips")
# → Returns past procedures, failures, and successful strategies

# Report outcome → procedures evolve
m.procedure_feedback(proc_id, success=False,
                     context="Dropdown fix stopped working")
# → Procedure auto-evolves to a new version
```

Works with any agent framework — CrewAI, LangChain, AutoGPT, custom loops. The agent just calls `add()` after actions and `search()` before decisions.

## Self-Hosted (Ollama)

When running locally with Ollama, use models with **8B+ parameters** and **8K+ context window**. The extraction prompt is ~4,000 tokens — smaller models will hallucinate or mix examples with real data.

| Model | Parameters | Works? |
|-------|-----------|--------|
| `llama3.1:8b` | 8B | Yes |
| `mistral:7b` | 7B | Yes |
| `gemma2:9b` | 9B | Yes |
| `llama3.1:70b` | 70B | Best |
| `phi4-mini:3.8b` | 3.8B | No — context too small |

### Quota Headers

Every authenticated response includes usage headers:

| Header | Description |
|--------|-------------|
| `X-Quota-Add-Used` | Add calls used this month |
| `X-Quota-Add-Limit` | Add calls allowed this month |
| `X-Quota-Search-Used` | Search calls used this month |
| `X-Quota-Search-Limit` | Search calls allowed this month |

SDKs expose this via `.quota`:

```python
m.search("test")
print(m.quota)  # {"add": {"used": 5, "limit": 30}, "search": {"used": 12, "limit": 100}}
```
