Intro
AI Avatar is a VRM 3D character in your VS Code sidebar that reacts to Claude Code / GitHub Copilot AI activity and Enter key.
Hooray!๐ I released version 4 of AI Avatar! My last post was about version 2, and there have been 2 big updates since then. Version 3 is the release of the Chrome Extension version, and version 4 is the release of the Animation Editor. Now, AI Avatar has popped out of VS Code and into the web. Let's take a look at how they are.

Chrome Extension Version
AI Avatar was working only on VS Code. But wait. Users might want to stay with their beloved avatar and get cheered not only when coding but also when browsing websites. This is really a serious problem, and I rushed to create a Chrome extension version.
The Chrome extension also runs on Edge. I heard that about 70% of users use Chrome and about 10% use Edge, so making a Chrome extension version can cover most of the users waiting for website support.
Creating both the VS Code version and the Chrome version will be quite hard, but my mission is to make people happy, so I proceeded while imagining the smiles of the users. I tried to make the coding process efficient and not create two full versions, but only code the diff for Chrome since I had already created the VS Code version.

Animation Editor

The previous Pose Editor could only set one pose per animation, for example, the avatar could only extend its arms. But now, with the Animation Editor, the avatar can set several poses in one animation, so it can do things like bend its arms first and stretch them out later. The Animation Editor can make your avatar more lively! I rewrote all the default animations included in AI Avatar from a single pose to full animations, so please enjoy the moves. This is a sample animation demo.โ
AI Avatar CodePen Demo
This is a minimal CodePen demo of the AI Avatar. Check out the angel-like smile and the avatarโs awkward movements! The actual AI Avatar has a Animation Editor, so you can make the movements less awkward. โ
