Save voice memos, notes, PDFs, articles and YouTube videos the moment they matter. Months later, ask a question in plain words and get back the ideas you'd forgotten you had, instead of researching it all again.
An example: 500 thoughts saved over five months. A voice memo, a YouTube video, a PDF of market research, a note about pricing, a thought recorded at 1 a.m. Then one question.
You've had five, spread over five months:
Every idea links back to where you saved it. Ask in your app, or from your own Claude.
Speak, type, drop a PDF or paste a link. Articles and YouTube transcripts are fetched for you and kept whole.
Every thought, and every passage of a long video or PDF, is indexed by meaning. Search “pricing” and find the voice memo where you said “what to charge”.
Ask in plain words, in your app or from your own Claude. It answers from what you saved and shows where each idea came from.
A brain this useful holds everything you think. So it lives on your own accounts, and the locks are built into the database itself.
Lock one: anyone holding only your public key can't touch your data at all. Lock two: a signed-in person sees only their own rows. Both live in your database, so they hold whatever app or tool connects.
Your notes go from your browser straight to your database, never through our servers. The coach sees only what you send it, and it never needs your notes, passwords or keys.
A coach walks you through each click and checks that every step works before moving on. Two months of coaching are included.
Your own database, login and web address, with both locks on.
Voice, PDFs, articles and videos saved in two taps, on any phone.
Search by meaning, links between related ideas, every passage findable.
Ask your own Claude about your notes, and save to your brain from any Claude chat.
Labels on every thought, and a weekly look-back of what you saved and what connects.
The coach tells you which tab to open, what to click and why, and checks each step works before moving on. Stuck? Drop in a screenshot. Nothing to install to get started.
The coach sees your steps and any screenshot you choose to share. It never asks for your notes, passwords or secret keys, and your brain never runs through our servers.
Your $25 is a one-time payment and never turns into a subscription. When your 2 months end, coaching simply stops unless you choose to continue for $14.99 a month, and you can cancel that any time. Your brain keeps working either way.
Your brain runs on services you sign up for yourself. Here's what each one costs you.
| Tool | What it does | Cost to you |
|---|---|---|
| Supabase | Holds your database, your login and the small server programs | Free |
| GitHub | Keeps your app's code and turns it into a website | Free |
| VS Code | Where you create and save your app's files | Free |
| Claude | Reads and adds to your brain when you ask (Stage 4) | Free plan works |
| Anthropic API | Labels every thought and writes your weekly look-back (Stage 5) | Pay as you go: about 10 cents per thousand thoughts |
| Supadata | Fetches YouTube transcripts automatically (optional) | Free for 100 videos a month |
A notes app finds the words you typed, in the notes you typed them in. Your brain searches by meaning across voice memos, YouTube videos, PDFs, web pages and notes together, down to a single passage in a long transcript. Ask your own Claude and it pulls what you saved into one answer, with where each idea came from.
No. They live in your own Supabase project, behind the two locks you set up in Stage 1, and they never pass through our servers.
Nothing on GitHub's and Supabase's free tiers. Stage 5's labels and look-backs run on your own Anthropic API key, billed to you per use: a few cents a month for most people.
Not for the coach, which is built into the site. You'll connect your own Claude in Stage 4, and a free account is enough.
No. The coach tells you what to click and why, and checks each step works before you move on.
Nothing, unless you want it to. Your $25 doesn't renew, and you're never charged automatically. If you're still building and want your coach, you can choose to continue for $14.99 a month and cancel any time. Your chat, progress and brain stay yours either way.
Yes. Add it to your home screen and capture by voice wherever you are.
Your first thoughts can be saved tonight: about an hour and a half from no accounts to your own app at your own web address.
