01 · Auto Layering
Drop an image. Get every layer ready.
Charios auto-detects every alpha island — head, torso, limbs, accessories — and exports each one as a transparent layer ready to rig.
- Auto alpha-island detection
- Joint magnets snap to bones
- Multi-select scale & rotate
02 · Easy Rigging
Move, edit, repaint — watch it live.
Drag a layer near a joint, snap it to the bone, see the deformation update in real time. Every edit ripples through the preview with no re-bake.
- Live-preview deformation
- Per-layer repaint
- Per-bone length & thickness
03 · Animation Library
Hundreds of mocap-ready animations.
Curated humanoid mocap ships in the box, plus drag-drop for any .bvh from CMU, Truebones or Rokoko. Bone lengths normalise automatically.
04 · Play test
Run your characters right in the editor.
Flip the test-run modal, pick Idle / Walk / Run / Jump / Attack from the chip selector, then drive the character with arrow keys. WASD, shift to run, space to jump.
- Action chip selector
- Live keyboard control
- 60 FPS in your browser

Frequently asked
Questions before you sign up.
Does Charios need a build step or install?
No. Open the editor in your browser, drop a PNG, you're rigging within seconds. Charios is a Next.js app on the public web — there is nothing to download, compile or configure.
Can I use my own mocap?
Yes. Drag any humanoid .bvh from CMU, Truebones or Rokoko, or any humanoid .fbx, onto the page. The retargeter normalises bone lengths automatically and extrapolates hand and foot bones when the source rig doesn't expose them.
Is it really free?
Yes. The whole editor is free — sign in with Google and your projects save to the cloud. There are no paid plans or credits.
Which game engines can I export to?
Unity prefab and a JSON skeleton today. GIF and PNG sequence for devlogs and itch.io. Godot import is on the roadmap; until it ships you can use the JSON skeleton with the open-source loader on GitHub.
Does Charios work on mobile?
The marketing site and dashboards are fully responsive. The editor itself is desktop-first because rigging needs precise pointer input and a roomy canvas — but viewing your projects, sharing previews and managing your account works on any device.
