It files itself
Name a few interests — your reno, a research thread, tabletop games. Every capture auto-routes to the right one. No folders, no filing, no empty-bucket guilt.
Pre-launch · Your second brain
Save anything. It files itself — and brings it back.
Text it, email it, share a link or an AI chat, snap a book cover, pipe it from your terminal — BrainTrellis reads whatever you send, auto-files it to the right interest, and sorts it into three simple lanes: Inbox, To-Do, Keep. Untended notes quietly compost away, and anything you kept is one plain-language question from coming back.
- No card to start
- Learns what to skip
- Export anything, anytime
just captured · 3 things → filed
- a link about GLM-5.2 open weights AI Tools
- a photo of a book cover Reading · book card
- a link you keep skipping muted · learned
Everything files itself. And it learns what to ignore — so it gets quieter, not noisier.
Every door in — including ones nobody else has.

Saving things is easy. The hard part is everything after.
Every app gives you a place to dump links. BrainTrellis does the three things that actually turn a pile of saves into something you use.
It learns what to ignore
Wave a card away and it remembers. BrainTrellis stops resurfacing what you keep skipping — the only second brain that gets quieter the more you use it.
It brings it back
A 5-card daily review and time-boxed catch-ups bring things back when you have time — so what you keep actually grows into something.
Every kind of capture, in one place.
A stray thought, a checklist, a link, a photo, a clip, a book you snapped, even a shared AI chat — auto-tagged and routed to the interest it belongs to.
A second brain that thinks with you.
Save anything — even AI chats
Links, photos, videos, voice notes — and shared ChatGPT, Claude, or Gemini conversations, captured as first-class notes. The thinking you do with AI finally has a home.
It pre-chews for you
An LLM summarizes and clusters what you save, so a tangle of fragments becomes a few coherent threads — ready to actually read, not just re-stack.
Find by meaning
Semantic search across everything you've kept. Search "that pricing idea" and get it — even if you never wrote the word "pricing."
Ask your brain
Pose a question in plain language — "what did I find about onboarding?" — and pull a synthesized, cited answer straight from your own captures.
Inbox → To-Do → Keep
Three simple lanes, no folders to babysit. Triage the Inbox, work the To-Do, and what you Keep stays put — untended notes quietly compost to Trash, so your interests get lighter, not heavier.
Folders inside interests
Group the notes inside an interest into named folders — Gear, Trip planning, Trail journal. One tap, no upkeep.
Share a corner of your brain
Invite your partner into an interest or folder. Their notes wait in a review lane until you wave them in — then catch up together.
Make it yours
A dozen hand-tuned themes — Dracula, Catppuccin, Nord, Tokyo Night — or import any VS Code theme. Light, dark, or match your system.
BrainTrellis vs. a pile of saved links.
Saving things is a great start. It's also where most apps stop — and where your best finds go to die.

For builders & AI power users
Your interests have an API. So does your AI.
BrainTrellis was designed agent-first. Capture, recall, map, and update over a clean four-verb API — secured by OAuth 2.1 with device flow. Wire it into Claude in one command, or drive it from your terminal.
- Hosted MCP server — Claude reads & writes your trellis
-
trellisCLI with device-flow login - OAuth 2.1 — PKCE, scopes, refresh tokens
- Personal API tokens for scripts & Shortcuts
# plug your trellis into Claude $ claude mcp add braintrellis # capture from anywhere — even a shared chat $ trellis capture "https://chatgpt.com/share/…" ✓ routed to "Tabletop RPGs" # pull a thread together $ trellis map "monster of the week" → synthesizing 9 related captures…
Three steps. Then it runs itself.
1
Capture anything
Type it, text it, share a link or an AI chat, pipe it from your terminal, or let an agent drop it in. One door for everything.
2
It routes & learns
Each capture files itself under the right interest, gets summarized into threads, and learns from what you keep — and what you skip.
3
You tend it
A daily review, a weekly nudge, and one-tap catch-ups bring it back when you have time — so what you kept grows into something.
Pairs with NewsTrellis. Drowning in newsletters too? If you also use NewsTrellis, hand any story to your Inbox in one tap — and your To-Do items can bubble up into your daily Brief. It plugs into the rest of your stack over MCP, CLI & a REST API, too. Two calm tools, one account — each great on its own.
Give your interests a place to grow.
Stop drowning your best finds in a feed you never revisit. Fire them in, and let BrainTrellis do the filing — and the forgetting.
