aftr connects Adobe After Effects to AI coding assistants — Claude Code, Cursor, and Google’s Antigravity — through a single open-source bridge on GitHub.
The project, posted on Show HN with 6 points and 2 comments, lets you work with After Effects from inside an AI coding session instead of manually keyframing in the GUI.
What it connects:
- Claude Code — Anthropic’s terminal-based coding agent
- Cursor — the AI-first IDE built on VS Code
- Antigravity — Google’s newer entry, described by early users as closer to Claude’s conversational style than Cursor’s IDE-integrated approach
The pitch: motion design workflows that normally require clicking through After Effects’ layer panels and effect controls can instead be driven through natural language in your coding environment. After Effects runs $22.99/month on top of whatever AI tool subscription you’re already paying for.
Most AI coding tooling targets web development and app building. Motion graphics has stayed mostly untouched by the vibe-coding wave because After Effects’ automation surface — ExtendScript, CEP panels — is obscure enough that most AI agents don’t know it exists. aftr gives that surface an AI front-end.
NOTE
Antigravity is Google’s play in the AI coding space, launched after Cursor and Claude Code established the category. It’s early — comparisons are anecdotal so far, with one user calling it “more of a vibe code like Claude.”
The repo is live and open source. If you’re already scripting After Effects with ExtendScript, aftr wraps that API for AI assistants. If you’re not, the learning curve is AE’s scripting model itself — aftr just changes who writes the code.
