A second brain that writes itself — and reminds you.
Dump in notes, docs, and screenshots. HeyBrian turns them into cited, interlinked pages you can ask anything — and resurfaces what matters before you forget.

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).
