AI for the people.

Mac with Apple Silicon (M1 or later).

Download blu

Version 0.2.1 · 7.1 MB

Installing

  1. Open the downloaded file, then drag blu onto the Applications folder.
  2. Open Applications and double-click blu.
  3. macOS asks once whether you're sure, because it came from the internet. Click Open.

blu is signed with an Apple Developer ID and notarised by Apple, so there is no security warning to work around and nothing to change in System Settings.

Before it can do anything

blu needs a model to talk to. In Settings, either paste an API key (Anthropic, OpenAI, GLM, Kimi, DeepSeek) or start Ollama or LM Studio to use a model already on your Mac.

Updates

blu checks for a new version when it opens and asks before installing one. If a chat is running, it says so first — installing restarts the app and ends that work.

What's in this version

A test of the update path itself. If you are reading this inside blu, the thing it was testing worked.

Fixed: an update could fail if it was installed in the first minute or two after a new version went up. blu would offer the new version, download the previous one from a cache, and refuse it because the two did not match. Each release now has its own address, so there is nothing stale to serve.

Nothing else has changed from 0.2.0.
