A second brain that writes itself — and reminds you.
Dump in notes, docs, and screenshots. Brian organises them into cited, interlinked pages, keeps them current as you add more, and resurfaces what matters before you forget. Not a chatbot you query — a brain that works while you don't.

Brian drafts interlinked, cited wiki pages — and keeps them current as you add more. A knowledge graph, not a folder.

reminds youIt works while you don't
Ask anytime and get cited answers — and Brian resurfaces what matters before the deadline, or before you forget.
Seed a brain, ask it, and watch the answer walk your own pages — no edits, no setup. This is the real interface.
The brain doesn't tell you what it knows. It tells you which page said it.
Your Q2 goals (wiki/goals/2026-q2): finish the investor deck — due Friday (wiki/admin/calendar) — and book the Japan trip for spring (wiki/travel/japan-2026, capped at $1,400).
Every claim opens a page in your vault. No sources = it says so. Nothing borrowed from training data.
Hand it the mess. An agent decides what each fact deserves — a page, an update, a cross-link.
New facts update pages instead of duplicating them. Cross-linked. Editable. Exportable as plain markdown.
It remembers what you've been thinking, not just what you've uploaded.
“What was my position on long context vs RAG?”
You concluded they compose (wiki/ideas/open-questions). You said it three weeks ago in chat.
Half-formed takes, the question you asked once and forgot — all retrievable the same way as your formal notes.
Same engine, different vault. Each is a brain with its pages cross-linked — ask a question that spans them and the answer traverses the graph and cites every source.
What did I decide about the Tokyo trip, and what's still open before I go?
The decision, from your notes: spring, not autumn — for the cherry blossoms and the cheaper Mar–Apr fare window; budget capped at $1,400; Kyoto for a few days mid-trip (wiki/travel/japan-2026). It also closes the "visit Japan" line on your Q2 list (wiki/goals/2026-q2). Still open, in order of lead time: 1. Renew your passport now. It expires in May; Japan wants 6 months' validity, and renewal runs ~4–6 weeks — that's the long pole (wiki/admin/documents). 2. Refill your prescription before you go — last refill was January, so you'll run out mid-trip (wiki/health/checkups). 3. Your car-insurance auto-renew hits while you're away — card on file expires this month, so update it or it'll bounce (wiki/admin/finance). 4. Mum's birthday is the 14th — you'll be in Kyoto. Send something ahead (wiki/people/family). 5. Book flights — still unbooked, and you're already over the $1,400 ceiling on current prices (wiki/travel/japan-2026).
Did I settle on travel insurance?
Not yet — you compared two providers last month and parked the decision until flights are booked (wiki/admin/finance). The cheaper option excludes adventure activities, so if the Hakone hike is still on the itinerary, the upgrade matters.
How am I tracking against Q2 goals overall?
Three of five on track, two slipping (wiki/goals/2026-q2): Japan trip is committed, the investing-reading list is half done (wiki/learning/investing), and the daily-routine cadence is holding. Slipping: the strength-training block (missed two weeks per wiki/routine/daily) and the family-call cadence (last entry was three weeks ago in wiki/people/family).
