Make your mark.

Open Brush settings from the brush toolbar and you get a draggable panel with a live preview stroke at the top that re-renders as you drag sliders, so you can see what a setting does before committing a single mark. A few things to know up front:

• Lite and Pro — The panel opens in Lite mode showing the essentials. The Pro toggle in the header reveals everything else: shape dynamics, smudge, color dynamics, anti-overflow, and more. The choice sticks per device.
• Brush type — The dropdown at the top swaps the brush onto a different archetype baseline (line art, paint, tone, fill, decoration) while warning you before discarding tweaks.
• Engine note — The deepest sections run on the GPU brush engine. On devices without WebGPU the panel says so and shows a simplified set, and brushes fall back gracefully.
• Control sources — Most jitter sliders have a small companion dropdown choosing what drives them: pure random, stylus pressure, tilt, rotation, stroke direction, or a fade along the stroke. That dropdown is the secret to brushes that respond to your hand.
• Save and reset — The bottom bar saves the current state as a named preset, or resets your tweaks back to the preset's defaults.

Built-in brushes are grouped by job: line art, painting, tone, fill, and decoration. Pens stay crisp at speed, paint brushes blend, tone brushes lay down screentones, and decoration brushes stamp patterns. In pixel art mode you get a separate hard pixel brush that never anti-aliases.

Tone brushes like Comic Dots put their own Quick Mix controls at the top of the panel: dot size, brush width, softness, strength, spread, and variation, plus a tile picker for the pattern itself (dots, lines, verticals, diagonals, grid, crosshatch, stipple, or an image you upload).

Quick size from the keyboard, anywhere: ] bigger, [ smaller.

A stroke is a row of stamps. This section shapes the stamp itself, before any randomness:

• Tip image — The artwork being stamped. Pro mode lets you swap in a custom tip image.
• Hardness (0-100%) — Edge crispness. 0% is a soft airbrush bloom, 100% is a hard pencil-like circle.
• Roundness (10-100%) — Squashes the tip into an oval. 10% is a thin sliver, which is your calligraphy nib.
• Angle (-180 to 180) — Rotates the tip. Low roundness at 45 degrees gives you a chisel point.
• Spacing (1-200%) — Gap between stamps as a percentage of brush size. 5-15% reads as a solid line, 50%+ becomes visible dots for stippling.
• Blend mode — How strokes composite onto the layer: Normal, Multiply (darkens, used by Charcoal and Watercolor), Screen (lightens, for glow), Overlay, Darken, Lighten, Color Dodge, Color Burn, Hard Light, Soft Light, Difference.
• Flip X / Flip Y — Mirrors the tip for the whole stroke, so asymmetric tips point the other way.
• Brush projection — Stylus tilt warps the tip into a perspective ellipse, like a flat brush leaning over. Needs a tablet that reports tilt.
• Orient to screen — Locks tip rotation to your screen instead of the canvas, so a nib keeps pointing the same way even after you rotate the canvas.
• Subpixel rendering — Smooth interpolated stamp edges (default). Turn it off for crisp aliased pixels on pixel-art style brushes.

Pattern

• Pattern — A tileable image stamped along the stroke: procedural dots, hatch, lines, or your own uploaded tile. Off for plain brushes.
• Pattern scale (4-128px) — Size of one tile. Smaller is denser, larger is chunkier.

Per-stamp variation, so strokes stop looking machine-made. Each jitter can be driven by its Control dropdown (pressure, tilt, fade, and so on):

• Size jitter + Min size — Random size per stamp, with a floor so the brush stays legible.
• Angle mode — Fixed (uses the fixed angle), Follow stroke (rotates with your motion, good for leaves and hair), or Random.
• Angle jitter — Extra random rotation stacked on any angle mode.
• Roundness jitter + Min roundness — Random per-stamp squash. With angle jitter you get the scattered-petals look.
• Flip X / Y jitter — Probability of mirroring each stamp, for breaking up repeated texture.
• Bristle splay — With a tilted stylus, sibling stamps fan out sideways like fraying bristles. Inker and Brush Pen use this.

Scattering

• Scatter — Flings stamps off the stroke spine. Grass, sparks, splatter.
• Both axes — Scatters along the stroke too, for chaotic spray.
• Count (1-16) + Count jitter — How many stamps drop per spacing tick, and how much that varies.

The tooth. This is what makes charcoal feel like charcoal:

• Grain + Grain scale (4-128px) — Paper-grain noise punched into each stamp, and how fine the tooth is.
• Grain source — The built-in procedural noise, or upload your own paper texture (tileable greyscale works best).
• Grain brightness / contrast — Tune an uploaded paper scan without re-uploading: shift the grain lighter or darker, flatten it or punch it up.
• Grain movement — Rolling (paper fixed under the stroke), Per stroke (paper shifts each stroke so valleys never line up forever), or Stamped (each stamp re-samples its own patch).
• Depth + jitter + min — How strongly the pattern modulates each stamp, with optional per-stamp variation.
• Texture each tip — On: every stamp gets its own decal-like texture. Off: texture is anchored to the canvas so overlapping strokes line up like real paper.
• Texture mode — How pattern combines with the stamp: Multiply reads as paper tooth, Screen and Overlay turn it into glow tricks.
• Dry threshold — Skips paint where the grain dips under a pressure-scaled threshold, which is the stuttery dry-brush skip in Chalk and Charcoal.
• Directional darken — Pencil physics: strokes perpendicular to the lead deposit darker than strokes along it. Cross-hatching gets that for free.
• Noise — Per-pixel film-grain speckle on soft edges. Different from Grain, which is the paper.

Dual brush

A second tip stamped on top of every primary stamp:

• Enable + Size (1-200px) — Turn it on and size the secondary tip, usually smaller so it reads as detail.
• Spacing, Scatter, Count — The secondary gets its own packing, spread, and stamps-per-tick.
• Mode — How it composites onto the primary: Multiply for grain, Screen for shine, Hard Light for chunky overlay.

Color dynamics

• Per stroke — Roll the color variation once per stroke instead of per stamp. Foliage without confetti.
• FG / BG jitter + Secondary color — Each stamp blends between your brush color and a second color you pick. Two-tone grass in one pass.
• Hue / Saturation / Value jitter — Per-stamp color wobble in each channel. Hue at 100 can swing the full color wheel.
• Purity (-100 to 100) — Pushes every stamp toward grey or toward full saturation before the jitters apply.

Transfer

• Opacity — The ceiling: the darkest a single stroke can get no matter how much you scrub.
• Flow — The per-stamp deposit rate. Opacity 100 with Flow 20 builds slowly to black; Opacity 30 with Flow 100 slams instantly into light grey.
• Opacity / Flow jitter + mins — Per-stamp variation on both, with floors. Low flow plus jitter feels like soft graphite.
• Build-up (airbrush) — Removes the per-stroke cap entirely so paint keeps accumulating while you hover and scrub, like a real airbrush.

Pressure

• Pressure to size / opacity / flow — Three independent toggles for what stylus pressure controls.
• Response curves — Each of the three mappings has an editable curve. Bow it up so light pressure already hits hard, or down for an inker-style snap from thin to thick.
• Min pressure size — The size floor at zero pressure. Around 5% gives line art its sharp tapers.

No stylus? Pressure simply reads as full, and everything still works.

Smudge / wet

Mixer-brush behavior: the brush picks up canvas color as it moves.

• Smudge — Master strength. 0 deposits pure paint, 100 purely smears existing pixels.
• Smudge length — How wet the load stays: 0 picks up new color instantly, 100 never lets go of the first pickup.
• Mix — The deposit ratio between carried canvas color and your brush color.
• Wet edges + width — Watercolor tide-lines: pigment pools and darkens at the stroke perimeter, from a hairline rim to a fat pool.
• Wet diffusion — Periodically bleeds the in-progress stroke into surrounding paint for the wet-on-wet halo.
• Burnt edges — Darkens stamp edges like graphite buildup or scorch. Different from wet edges, which is about pigment pooling.
• Wet mix only — The brush deposits no fresh color at all, it only pushes pixels around. That is the Smudger preset in one toggle.

Brush pose

Mouse user borrowing a tilt-dependent brush? Pose locks pressure, tilt, and rotation to fixed values of your choosing, so every tilt trick works without a tablet.

How your raw cursor movement becomes a stroke:

• Smoothing — Stabilizes wobbly hands by letting the brush trail the cursor. Higher is smoother but laggier. Great for line art, wrong for loose sketching.
• Stabilizer style — Streamline (springy Procreate-style catch-up, with its own falloff slider for how stiff the spring is), Weighted (light moving average, lowest latency), or Lazy mouse (the brush hangs behind the cursor on a string, best for long deliberate curves).
• Wobble + scale — Drifts the stroke centerline smoothly off your path while keeping edges clean. Syrupy cartoon ink and hand-drawn imperfection on demand.
• Width wobble + scale — Breathes the stroke thickness up and down even at constant pressure, for chunky ink that fattens and thins naturally.
• Taper start / end (0-60 stamps) — Fades the stroke in and out so lines start and finish in a point instead of a blunt cap. Quick taps are protected, the taper never eats more than half a stroke.
• Fade steps — How many stamps a Fade control source takes to ramp from full to zero.
• Pencil only — Ignore fingers and mouse for drawing so a resting palm can't leave marks. Pan, zoom, and eyedropper still work by touch.

• Anti-overflow (Strength, Threshold, Close gap) — Don't-cross-the-lines mode: the brush clips itself against your line art so flats can't escape the outline. Threshold decides how faint a line still counts as a wall, and Close gap (up to 12px) seals small holes in the lines so color can't leak through. Soft edges and pressure survive.
• Decoration tips — Particle-hose brushes carry a set of tip images (sparkles, leaves, hearts) and either cycle through them in order or pick randomly per stamp.

Dialed in something you love? Save it as a custom preset with its own name. Custom presets keep everything: settings, dynamics, and the brush tip. They're stored in your browser, so they follow the device you saved them on. The stock presets themselves never change, your tweaks live on top, and Reset takes you back to baseline any time.

The brush browser is a public shelf of brush packs made by other bakas. Browse by newest or most installed, search by name, and install with one click. Installed brushes show up alongside your custom presets, and you can remove a pack whenever you like.

• Publishing your own: a pack bundles up to 12 brushes with a name and description, and custom tip images ship inside it, so your brushes look identical on everyone's canvas.
• Packs are self-contained copies. Updating or deleting your pack never breaks anyone's installed setup mid-drawing.
• Installs are checked and cleaned: settings get clamped to safe ranges, and a pack can never touch your own tool preferences.
