Paint with light. Hear every stroke.
SYNTHLUCIDA Canvas is a drawing app for your browser where a soft ambient tone follows your brush while you paint. Higher up the canvas sounds higher, lower sounds deeper, always in a calm scale. Add glowing brushes, 34 coloring pages and gentle animation, with no sign-up.

What it is
Canvas is a free drawing app that runs right in the browser, and a quiet instrument at the same time. You don't install anything or create an account: open it and start painting. Every stroke plays a soft tone, so drawing turns into a slow, calming little piece of music. Use the glowing brushes on a blank canvas, or pick one of the coloring pages and fill it with a tap.
Painting with sound
This is what makes Canvas different. The moment your brush touches the canvas, a soft ambient tone starts to follow it.
Height is pitch. Higher up the canvas plays a higher note, lower plays a deeper one, gliding smoothly as you move.
Always in tune. The tone is locked to a calm five-note scale, so nothing you draw can sound "wrong".
Left and right. The sound pans with your brush across the stereo field, which is lovely on headphones.
Soft edges. Each note blooms in slowly and fades out when you lift your finger, with a light touch of reverb.
Every brush has a voice. SOFT, INK, CHALK and NEON each color the tone a little differently. The eraser plays its own muted note, and every fill rings a small chime.
You set the volume. Turn the sound off with the speaker button, or set the level with the slider (40% by default). Both choices are remembered.
34 coloring pages
Mandalas, animals, nature scenes and more, drawn with lots of small areas to fill. Tap an area with πͺ£ FILL and it fills with your color, which always stays under the outline. Drag to paint freely with any brush instead.
These were colored in the app itself, just by tapping. CLEAR wipes only your painting, never the page, and βΊ UNDO takes back any step.
What's inside
Four brush feels
SOFT is a gentle watercolor wash, INK a tapered brush pen, CHALK a dry grainy pastel and NEON a bright glowing light trail. Add a β¨ sparkle trail if you like.
One-tap fill
πͺ£ FILL colors a whole area with one tap. It works on coloring pages and on your own closed shapes on a blank canvas.
Bring it to life
Mark a part of your drawing, like a wing or a leaf, and give it one of 10 gentle motions: flap, sway, spin, bob, pulse, fade, drift, twinkle, shake or rainbow. Press π¦ LIVE and watch it move.
Text & emoji
Write words in 12 graphic styles such as neon, gold, fire, ice or synthwave, or drop in any of 70 emoji. Text can animate too.
Replay & export
βΆ ANIMATE replays your drawing stroke by stroke. Save it as a PNG image, an animated GIF or a video (WEBM, or MP4 in browsers that only record MP4).
12 moods
Themes like SPACE, AQUA, LAVENDER or the calm ZEN change the backdrop and glow around the canvas without touching your colors.
Phone, tablet, desktop
Paint with a mouse or a finger. On a phone in portrait the canvas stays at the top while the tools scroll underneath, and fullscreen mode hides everything but your picture.
Free, no account
No sign-up, no ads, nothing to install. Your color, brush, theme, sound and volume stay as you left them for next time.
A calmer mind: pair it with breathing
Slow painting with a soft sound is a nice way to switch off for a while. To go a step further, combine it with a few minutes of guided breathing in UklidniTo. It's a free breathing app from the same family, with techniques like 4-7-8, Box and Coherent breathing and a pulsing orb that sets the pace.
Breathing slowly first and then painting with sound, or the other way round, can help quiet the mind and lower stress. It makes a short break you can take anytime.
Open UklidniTo βHow it works
Open Canvas in your browser. There's nothing to install and no account.
Pick a color and a brush feel, then paint. Listen to how the tone follows your hand.
Or choose a page under CHOOSE A PAGE and tap its areas to fill them.
Bring it to life with β MARK PART and π¦ LIVE, or add a word or an emoji.
Save it as a PNG, a GIF or a video of the stroke-by-stroke replay.
Questions
Is it free?
Yes. There's no account, no ads and no in-app purchases.
What does the sound do?
While you paint, a soft ambient tone follows your brush: higher on the canvas plays a higher note, lower a deeper one, and it pans left and right with your stroke. It's always tuned to a calm five-note scale, so it never sounds wrong.
I don't hear anything on my iPhone.
Check that the ring/silent switch isn't set to silent and that the volume is up. In the app, the π button toggles the sound and the slider next to it sets the volume.
Is my drawing saved?
Your settings are remembered, but the painting itself isn't kept after you close the page. Save it as a PNG, GIF or video before you leave.
Does it work on a phone or tablet?
Yes. You can paint with a finger, and on a phone in portrait the canvas stays at the top of the screen while the tools scroll underneath.
