+# SecondBrain
+
+**A local-first, privacy-scrubbing personal memory.** Point it at everything you produce —
+notes, code, agent transcripts, event logs — and get one command back:
+
+```bash
+brain recall "what did we decide about pricing" --hybrid
+```
+
+- 🔒 **Secrets scrubbed before storage** — PEM keys, JWTs, `sk-…`/`ghp_…`/AWS keys, `password:`/`token=` patterns are redacted *before* a chunk is ever embedded.
+- 🏠 **100% local** — embeddings via your own [Ollama](https://ollama.com) (`nomic-embed-text`); storage is one portable `brain.db` ([sqlite-vec](https://github.com/asg017/sqlite-vec)). No cloud, no API keys, no egress.
+- 🎯 **Hybrid recall** — dense KNN + FTS5/BM25 fused by reciprocal-rank-fusion, so *meaning* and *exact identifiers* (invoice #, IBAN, paths) both hit.
+- 📦 **Redeployable anywhere** — single file, env-configured, systemd + Docker included.
+
+## Pages
+- **[[Architecture]]** — data model, ingestion, scrub guarantees, RRF fusion math
+- **[[Deployment]]** — local, systemd timer, Docker, GPU offload
+- **[[Components-Roadmap]]** — sister components being extracted from the Atlas stack
+
+## 60-second start
+```bash
+ollama pull nomic-embed-text
+git clone https://git.atlascorporation.nl/atlas/secondbrain && cd secondbrain
+bash deploy/install.sh && . .venv/bin/activate
+python3 brain.py ingest-files ~/notes
+python3 brain.py embed
+python3 brain.py recall "your question" --hybrid
+```
+
+## The senses
+| Sense | Command | Ingests |
+|---|---|---|
+| Files | `ingest-files <dir>` | code, docs, config (60+ extensions) |
+| Transcripts | `ingest-transcripts <dir>` | `*.jsonl` agent sessions |
+| Events | `ingest-events --db <sqlite>` | structured `events(ts,sense,subject,payload)` |
+
+Adding a sense is ~10 lines: `chunk → scrub() → _stage()`.
