BUILT FOR YOUR NEXT SESSION

# The Living Memory Engine for AI-First Engineers

Passively distil raw AI chat sessions into permanent architecture decisions and reusable, prompt-injectable context blocks.

01 / THE MEMORY PIPELINE

## From conversation to compounding knowledge.

Keep the insight. Lose the noise. Give every new session a head start.

Ask your AI client to save the session. Capture the reasoning in the same place you do the work.

`save_chat_as_doc({ transcript, project_id })`
02 / SIGNAL OVER NOISE

## A long conversation.

A lasting memory.

Your next AI session doesn't need every debugging attempt. It needs what worked, why it worked, and the constraints worth remembering.

# Search architecture

## Key facts
- PostgreSQL + pgvector with HNSW indexing.
- Semantic and full-text arms run independently.
- Reciprocal rank fusion combines ranked results.
- Every query is scoped to the authenticated user.
```

ai_context_snippet

Use PostgreSQL + pgvector with HNSW indexing. Fuse semantic and full-text search with RRF. Keep results scoped to the authenticated user.

03 / ENGINEERED FOR CONTINUITY

## A second brain for your engineering stack.

### Passive Chat-to-Doc Distillation

Stay in Claude Code, ChatGPT, or Cursor. One capture turns your conversation into documentation that lasts.

### Model Context Protocol (MCP) Native

Capture, search, and recall from your AI client. Your engineering knowledge becomes a tool your model can use.

### Subtractive Noise Reduction (Zero-Fluff Code)

Keep the final implementation and the reasoning behind it. Leave the dead ends behind.

### Hybrid Vector & Full-Text Search (RRF)

Semantic understanding meets exact identifiers. Reciprocal rank fusion brings the right context to the surface.

### Local-First & Self-Hosted Privacy

Your infrastructure, your Postgres, your AI keys. Self-host with a local model to keep your knowledge on your machine.

### Prompt Real-Estate Optimization

Compact context snippets give your next session the facts it needs without the transcript it doesn't.
