Brainstead learns each client's brand voice from their own material. Paste the client's website and the brain reads up to 25 pages into knowledge; add brand files and skills, and every account manager drafts from the same source.
Every draft names its voice sources in the reviewer notes and marks unsupported claims as [NEEDS-FACT]. A brain is plain markdown files; export, so you can take it with you, is in development. It runs on Claude by default, or another frontier model your client chooses.
Design-partner stage · priced per client brain, not announced
How to
Add the address when you create the brain. It reads up to 25 pages into knowledge/website/, one markdown file per page.
Put tone-of-voice guides, approved copy, product sheets and do-and-don't lists into brand/ as markdown files.
Skills such as /draft set the house rules for each kind of request: length, structure, what to check. Edit them as markdown.
In the client's Slack channel: @brain-harbour /draft a short LinkedIn post about the new roastery.
Each draft lists where its voice came from, phrase by phrase, and flags anything it couldn't source as [NEEDS-FACT].
Good to know
If the client's site is mostly images or a single page, the brain has little to learn from. It says so in the reviewer notes, for example "no brand/ folder yet, voice taken from site copy", rather than inventing a style. Two or three pieces of approved copy in brand/ usually fix it.
Inside the brain
A brain is a folder of plain markdown. knowledge/ holds what the brain has read, starting with up to 25 pages of the client's website, one file per page. brand/ holds the files you add: tone guides, approved copy, product sheets. skills/ holds the instructions for each kind of request, such as /draft.
Nothing is hidden in a model's memory. If a draft sounds wrong, you can open the file it learned from and change it, and the next draft follows.
Handovers
In most agencies a client's voice lives in the heads of the two or three people who work on the account, plus a style guide nobody opens. When one of them moves on, the next drafts drift. With Brainstead, the voice is in the client's brain, so the next person starts from the same sources and the same reviewer notes.
What it adds
[NEEDS-FACT] markers instead of invented claims.Questions
Yes. Everything the brain knows is markdown in knowledge/, brand/ and skills/, and you can edit any of it.
The brain tells you in the reviewer notes. Add approved copy or a tone guide to brand/ and the next draft uses it.
Not automatically. You decide what goes into brand/, so the voice changes only when someone changes it.
A brain is plain markdown any tool can read. Export, so you can take it with you, is in development.
Brainstead is priced per client brain, not per seat. Pricing isn't announced yet.
It isn't a design or asset tool, and it doesn't publish. It drafts text in the client's voice for a person to review.
