What it does

Everything a cartoon needs

A hand-drawn line that boils, and a stroke drawing itself on

Lines with character

Vector drawing that feels hand-made — and can stay alive.

  • 12 line brushes: solid, ink, calligraphy, pencil, marker, chalk, dry brush, sketchy, wavy, splatter, dotted, dashed
  • Animated “boiling” lines
  • Per-point line width and per-branch visibility for draw-on effects
  • Smooth, Bézier and NURBS curves
  • Masking, with outlines on the clipped result
  • 26 palette presets, skin tones included
  • Gradient fills and lines, feathered fills, boolean shapes and text layers

Rigs that behave

Bones, controllers and IK, built for cartoon characters.

  • IK with pole targets, angle limits and an IK/FK switch without a jump
  • Joysticks that blend up to nine poses from one handle
  • Blend shapes and correctives driven by bones or joysticks
  • Rig templates: humanoid, face, 360° head, spring hair, soft belly
  • Follow-through springs, wobbling flesh and shape-keeping physics with collider bones
  • Meshes with smooth weights; controllers with 25 handle shapes

Timing you can see

A timeline and a graph editor made for posing, not for spreadsheets.

  • A graph editor with tangents (auto, spline, linear, flat, free) and extrapolation: cycles, offsets, ping-pong
  • Motion paths you edit on the stage: drag keys, bend the path with handles
  • A tween slider and curve tools: simplify, smooth, bake, Euler filter
  • A timeline with markers, a play range, hold bars and stretchable timing
  • Onion skin, and moves in one click: bounce, anticipation, overshoot, wiggle, walk cycles

Mouths that talk

Switch layers swap whole drawings — made for mouth charts.

  • A drawing strip to pick the shape for each frame
  • Automatic lip-sync from audio, re-run when the sound changes
  • Blinks through a whole shot, and blend-shape mouths on a joystick
A camera frame shaking over a night scene

A camera with nerves

Moves and shakes that make a shot feel held, driven or hit.

  • Shakes: handheld, walk, run, vehicle, earthquake, impact, vibration, drift
  • Moves: push in, pull out, pan, tilt, Dutch angle, snap zoom, Ken Burns
  • Follow a layer or a bone; smooth the camera; impact frames
  • Guides, safe areas and aspect masks; an overview of the camera over the scene

Render and ship

From a quick preview to the final master, soundtrack included.

  • Quick render, and final MP4 (H.264), ProRes 4444 or WebM with transparency
  • PNG and OpenEXR sequences, GIF
  • Presets, a render queue and burn-in for review copies
  • Render jobs split across workers, with a report
  • Review notes and approval: in progress, in review, approved, published
Commands flowing over MCP between an AI agent and ToonFlick AI MCP

Ready for AI agents

Every one of its 130+ commands can be driven over MCP, so AI agents can work in the studio too.

GPU from the ground up

Rendered with wgpu, written in Rust, built from modules.

Performance

Fast by design

ToonFlick is built GPU-first. Rendering runs on the GPU (wgpu, 4× MSAA), the CPU work — rig, IK, tessellation — is spread over all cores, and nothing is redrawn while nothing changes.

1.3 ms
of work per frame for one character
4.9 ms
for 5 characters + 1,000 shapes
500k triangles
at about 20 fps — 20 characters + 5,000 shapes
2M triangles
still interactive at about 7 fps — 50 characters + 20,000 shapes
Frame budget at 24 fps

At 24 fps a frame has about 42 ms, so typical scenes use only a small fraction of the budget.

Measured during playback on an RTX 5080 with 16 CPU threads, at 1920×1080.

A look inside

Screens

The ToonFlick window in Animate mode: tools on the left, the stage with Pip in front of the motel and the Controls panel in the middle, layers and properties on the right, the timeline at the bottom

Three leg rigs side by side: A FK keyed by hand, B IK moved by the foot controller, C IK with a pole target and a knee limit
Knees three ways: FK, IK, and IK with a pole.
The Graph editor under the stage: a bouncing ball’s curves with four keys picked and their tangent handles, and the ball’s motion path on the stage with a picked key’s handles
