Not another talking-head AI video tool
Turn any doc into a whiteboard explainer.
Paste a doc, a link, or one sentence. openCanviz draws the explanation on paper, idea by idea, narrated from your own source. Then you can change any single line of it.

The same idea, drawn in different styles.
Every sample below was generated from a doc or a one-line prompt, then drawn on paper by the pen you can see moving. Pick a style per video, or mix them scene to scene.

And here's the part they never show you
Watch one paragraph become a scene.
Anyone can show a finished reel. openCanviz shows the decisions behind it — and lets you change every one.
The paragraph you pasted
When you type a URL and press Enter, your computer first asks a DNS server where the site lives, then opens a connection and pulls the page down.
Concept → object
“type a URL”
A browser with an address bar, drawn first because the sentence opens on it.
Ordering & reveal
“asks a DNS server”
A labelled server the arrow draws toward, added as the narration names it.
Narration timing
“opens a connection”
One take, sliced on word timings so the voice lands as each stroke finishes.
Why openCanviz
They show you the output. We show you the wiring.
Most people never open the timeline. And if you want fine control, it's all there, no code needed.
For everyone
Watch first, tweak a little
You start with a finished video, not a blank editor. A few simple controls cover most changes.
✓
Change the tone or the voice in one click
✓
Swap the background, or drag to reorder chapters
✓
Redo any scene by describing it in a sentence
For the picky
Change one thing, not the whole scene
Here’s what other AI video tools can’t do: click one box, one label, one arrow, and change only that.
✓
Fine-tune how each element moves, and when
✓
A full timeline, tracks, and camera when you want them
✓
No code to learn, and none needed
