Stop re-explaining yourself to Claude.

Brain gives Claude lasting, organized context about you — who you are, what you're working toward, how you like to work — so it's there in every conversation, instead of vanishing when the chat ends.

Your best thinking is trapped in old chats.

Every new conversation starts from zero — your context, your goals, the way you work, all re-explained from scratch.

A brain is more than memory.

It's the context that makes Claude actually know you — kept in one place, organized the way you think.

Identity

Who you are — your role, your world, the facts that hold steady.

Goals

What you're working toward, on the horizons that matter.

Strategies

How you operate — your playbooks for the things you do often.

Preferences

How you want AIs to work for you, kept as standing rules.

People

Who's in your world, and what matters about each of them.

Voice

How you sound, so anything written for you sounds like you.

Two ways to remember, the way you actually think.

Thoughts for what you want to remember

Just need to get something down? Tell Claude — it's kept: flat, taggable, instant. No filing, no deciding where it goes.

Pages for what's worth keeping

Some conversations are too good to lose in a thread. Turn them into a page — organized, durable, easy to find again.

Jot it down now. Organize it later — only when it's worth keeping.

You just keep talking to Claude.

01 Claude fills it

Durable facts become thoughts and pages as you talk — nothing to file by hand.

02 Claude recalls it

“What did we decide last week?” It reads your brain back when it's relevant.

03 It goes with you

Your context travels to every chat, device, and agent. Build it once.

Start remembering instead of re-explaining.

Connect Brain to Claude in a minute. From your next conversation on, it knows you.
