Nowadays we are all lost in a sea of thoughts.
And every new AI chat starts from zero.
Hindbrain gathers what mattered from your sessions into a project brief that stays current over time.
Join the waitlistWhere was that project left?
A brief holds one named project
What it is, constraints, and only the context you wrote, plus a thin next list. If it is not in the brief, Hindbrain does not invent it.
What should we build next?
The brief already has the current focus for this project, and a short follow-up list after that.
Hindbrain brings clarity.
Take the brief with you
A local hop writes it for another tool today. You attach that file so the next session already has the project.
When the same attach works in a web chat, we send a short note.
Leave an email
We write when you can attach a brief from a browser, in the tool you already use.
How it works
Gather
What mattered in your sessions becomes one named project brief. A coding chat, a design pass, and a research dump can all feed the same brief for that project.
Keep
You confirm what can enter the brief. A constraint you accepted, or the next task you named, can land after the chat ends. The brief stays current.
Attach
The project brief is formed and you can take that same brief into the next tool, where it will keep evolving. The project is already there.
Why Hindbrain
Your hindbrain is older than planning. It keeps breath, balance, and practiced motion going so the rest of the brain can do the new thing.
Hindbrain keeps what mattered in one brief: what the work is, what you confirmed, what is next. You attach that brief and start on the new work.

Questions
- What can I use today?
- A project brief format and a local hop in this repo. This page is the waitlist for hosted attach.
- Do I install a CLI to join?
- No. The waitlist is for attaching a brief in a web chat. You do not install anything to join.
- Is this a notes app?
- No. You do not come here to file notes or run a general task list. The unit that travels is a project brief.
