Second Brain Service
A "save everything" knowledge management backend. Captures links, notes, PDFs, images, and documents. AI classifies everything automatically. Supports keyword, semantic, and hybrid search.
Architecture
brain-api → FastAPI REST API (port 8200)
brain-worker → RQ background processor
brain-db → PostgreSQL 16 + pgvector
brain-redis → Redis 7 (job queue)
brain-meili → Meilisearch (keyword search)
brain-browserless → Headless Chrome (JS rendering + screenshots)
Quick Start
cd services/brain
# Copy and edit env
cp .env.example .env
# Add your OPENAI_API_KEY
# Start the stack
docker compose up -d
# Check health
curl http://localhost:8200/api/health

Gateway Integration
The platform gateway proxies /api/brain/* to brain-api:8200/api/*.
Auth is handled by the gateway injecting X-Gateway-User-Id header.
The brain-api container joins the pangolin Docker network so the gateway can reach it.
Processing Flow
- User submits URL/note/file → stored immediately as
pending - RQ worker picks it up → status becomes
processing - Worker: fetches content, takes screenshot, extracts text
- Worker: calls OpenAI for classification (folder, tags, title, summary)
- Worker: generates embedding via OpenAI
- Worker: indexes in Meilisearch
- Status becomes
ready(orfailedon error)
Storage
Files stored locally at ./storage/. Each item gets a subdirectory:
storage/{item_id}/screenshot/screenshot.png
storage/{item_id}/archived_html/page.html
storage/{item_id}/original_upload/filename.pdf
S3-compatible storage can be added by implementing S3Storage in app/services/storage.py.
