NodeBrain v0.4.0

Setup no longer requires an API key, and the app guides you to your first agent.

Getting started is easier

Run AI locally, no account needed. Set up a private AI during onboarding — one download, nothing leaves your computer. Cloud providers still work if you prefer.
Guided API key setup. If you'd rather use an online service, NodeBrain walks you through getting a free key and stores it for you.
Simpler onboarding. The six-screen tour is gone. Setup ends with one button, and Agent Studio opens with examples you can click.

Chat and Agent modes. Chat answers questions; Agent builds and runs things.
Agents remember the conversation — you can ask follow-up questions.
Responses stream as they're written, with a model picker built into the input.
Agents read spreadsheets and Word documents in addition to PDFs and text files.
Agents get names and icons that reflect what they do.
Execution logs group into per-run cards showing what happened and whether it worked.

Integrations verify your credentials before showing as connected, with plain-language errors.
Local Filesystem has a folder picker instead of typing a path.
Web search is now free and needs no API key.
Agents can only read files inside the folder you authorize.
MCP integrations are pinned to specific versions so they can't silently change.
Credentials are better protected from the integrations running alongside them.
Interrupted tasks no longer sit stuck as "running".
Faster startup, a splash screen instead of a blank window, and a smaller download.

Optional usage data. NodeBrain can send anonymous counts and error types — off by default, chosen during setup or in Settings. Never your prompts, files, or credentials.
Code signing is still pending, so Windows may show a SmartScreen warning (More info → Run anyway).
