Windows SmartScreen

The Windows installer is not code-signed yet. Windows may show “Unknown publisher.” Verify that you downloaded it from the official Brainwrite releases repository before choosing More info → Run anyway.

Install an agent CLI

Brainwrite needs at least one supported agent engine installed and signed in. Claude and Codex are the most common starting points.

  1. Install the CLI from its official provider.
  2. Run it once in a terminal and complete sign-in.
  3. Restart Brainwrite.
  4. Open the model picker. Available engines appear normally; unavailable engines explain what is missing.

See Agent engines for the complete list and explicit path overrides.

Where data lives

Brainwrite stores its application data under ~/.brainwrite. Electron window and browser data use the normal per-platform application data directory.
