Everything
you've seen.
One search away.
Email, chat, tickets, docs — Third Brain's local AI sits with you across every tool, remembers it all, and tracks every promise you make. One place to ask. Nothing leaves your machine unless you say so.
One loop. Zero chaos.
Pulls every signal from the surfaces you touch — email, chat, meetings, GitHub — with more connectors on the way.
AI summarizes, links related items, extracts commitments, tags context, and kills noise.
Your personal AI agents score urgency using your priorities and past behavior. Only real work reaches you.
Drafts replies, creates tasks, files the noise, and queues follow-ups for your review — you stay in control.
Where did you see that ask — email, chat, a commit? One search box finds it, no matter which system it lives in. Never dig through four apps to find one thread.
Spots every "I'll do X by Friday" in any channel — yours and theirs — and turns it into tracked tasks with gentle reminders.
@all, FYI threads, low-priority pings = auto-muted or summarized. You set the rules once. It handles the rest.
Runs on-device (Qwen, Gemma via Ollama — or bring your own model) by default. Zero training on your data. Your brain, your rules.
Timed deep-work blocks where the noise waits for you. When you surface, everything that arrived is already triaged — not screaming.
Markdown notes, [[wiki-links]], backlinks, and a graph view — a knowledge base you own, in open formats you can export anytime.
Third Brain is also an MCP server: the context it builds — your notes, pages, tasks, and calendar — can plug into any AI you choose. A local model for sensitive work, a frontier model when you want the horsepower, whatever wins next year. The intelligence is swappable. Your context isn't — because you own it.
Big tech. Your laptop.
Audience of one.
The stack a SaaS company runs in a datacenter, running quietly on your machine.
SQLite FTS5 + sqlite-vec ANN + knowledge graph, fused into one ranked answer.
llama.cpp built in, Metal & CUDA. Qwen, Gemma, Ollama — or bring any frontier model.
Loro CRDT as source of truth. Offline-first, conflict-free, one SQLite file you own.
Entities, relationships, and communities extracted from your work — traversable in search.
Whisper speech-to-text and on-device TTS. Dictate and listen — no audio leaves your machine.
Device-to-device over your own LAN (QUIC + mDNS). End-to-end encrypted. No server involved.
A real tool-calling loop that searches your data before it reasons. Receipts, not vibes.
Your context, served to any AI client you choose — with tag-scoped allow/deny access.
AES-256-GCM secrets vault in your OS keychain, plus a BIP39 24-word recovery phrase.
Free forever for local use.
Pay only when you want more.

Your context is the most valuable thing you produce.
Keep it.
Every AI assistant wants your work context — your inbox, your channels, your files — accumulating in their cloud. Third Brain makes the opposite bet: your context builds up on your machine, works with any model, and never becomes someone else's moat.
