Turn prompts into editable 2D animations with Claude or Codex via MCP. Fine-tune layers and keyframes in the visual editor, add particles and motion paths, then save and reopen your project. Free, open source, and runs locally.

Hi Product Hunt! I’m Engin, the maker of Chorono.

Chorono is a free, open-source 2D animation editor built around a simple idea: create with an agent, then keep control over the result.

Connect Claude or Codex through MCP to turn a prompt into an editable scene. Then refine the typography, shapes, motion paths, particles and keyframes in the visual editor.

You can also create animations manually, save a portable project and reopen it for your next revision. The editor runs locally on your computer.

The demo shows the initial creation process at 8× speed, followed by a refined clock animation.

I’d love feedback on two things:

• How easy is it to create and refine your first animation?

• What would make Chorono useful in your own workflow?

Thanks for taking a look!

The create-with-an-agent-then-keep-control split is the part that got me. Agent-generated motion is usually 80% there, and the last 20% is all keyframes and pacing — exactly where most tools lock you out. Does the MCP round-trip preserve manual keyframe tweaks when the agent re-edits a scene, or does a re-prompt overwrite the hand-tuned parts? That's the thing that would decide whether I'd trust it in a real workflow. Free, open source, and local makes it an easy try either way.
