BrainHash: a digital brain you control.
BrainHash is a free product we built and run: a private notes and knowledge workspace for individuals and small teams. Capture ideas, keep them organised, and share them only with the people you choose.

The problem
Ideas end up scattered across sticky notes, screenshots, chat messages and draft emails, and sharing them usually means a public link anyone can forward.
What we built
Smart sharing
Share with selected users. No public links.
Controlled comments
Owners manage discussion; shared users stay focused.
Works everywhere
Mobile, desktop and tablet; log in from anywhere.
Security decisions
Private by default
A note is visible to the account that created it.
Named users only
Sharing is with people you choose, not a public link.
Roles
Owners and shared users don't get the same actions.
Account recovery
A lost device doesn't have to mean lost notes.
Session cookies
Sessions use secure, http-only cookies.

We started minimal on purpose. Each feature ships when it's solid.
What this means for your project
The same process we used here, a tight scope, security decisions made early, and a product we can operate after launch, is what we bring to your app.
