Or let DollyAI™ block it in — then paint over the top.
Generate style-locked concept frames in seconds, drop them onto a Draw layer, and refine by hand. The AI does the heavy lifting; you keep the authorship.

Every drawing lands on the storyboard, linked to its scene.
Send a finished panel straight to the storyboard editor — annotated, versioned and tied to the shot it illustrates. No exporting, re-naming or re-importing.

Under the Hood
Built for artists who demand performance
World-Beating GPU-Accelerated Rendering
Our custom, proprietary GPU-accelerated drawing engine renders at 60fps in your browser — no plugins, no installs. Four-phase performance pipeline purpose-built for cinematic storyboarding.
- GPU compositor for layer blending at native framerate
- Web Worker off-thread brush computation — zero jank
- Dirty-region rendering — only re-composite what changed
- OffscreenCanvas worker — zero main-thread dab pixel cost
- Dynamic overscan with auto-resize for large brush radii
- Snapshot cache for instant compositor recovery

Custom Brush Builder + 450+ Brushes
Our in-house brush builder gives you full control: pressure, flow, scattering, jitter, tilt, texture, dual-brush blending — the works. Ships with a library of 450+ ready-to-paint brushes.
- 450+ stock brushes across ink, pencil, oils, watercolour, charcoal, airbrush, gouache, chalk, markers, and bristle sets
- Custom brush builder — tweak every dynamic: size, hardness, spacing, scattering, jitter, angle, flow, pressure gamma
- Dual-brush blending for complex, textured marks
- Import any .abr brush file — your favourite packs come with you
- MyPaint engine: full .myb preset support for natural-media feel
- Smart pressure gamma curves make every stroke feel intentional

- 120+ high-resolution paper and canvas textures
- Cold-press, hot-press, rough, smooth — every surface a working illustrator asks for
- Texture depth, scale, contrast, and invert controls
- Per-layer texture overrides — not just document-wide
- Custom texture import for bespoke surfaces
- Cinematic storyboard paper presets (16:9, 2.39:1, 4:3, square)

// Full pressure + tilt
Full Stylus Pressure + Tilt
Every tablet, every stylus. Pressure sensitivity, X/Y tilt, and barrel rotation with five smoothing modes for pixel-accurate tracking on any device.
- Full pressure sensing with normalisation (0.0–1.0)
- X/Y tilt angle detection and pen barrel rotation
- 5 smoothing modes: None, EMA, Weighted, Stabilizer, Pixel Perfect
- Stabilizer mode: lazy brush with 3-sample ramp-up
- Spatial calibration overlay for pointer verification
- Pressure stress test with real-time histogram and response curve
