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.
Describe it, or paste a doc

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.
What Happens When You Type a URL

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

Redo the whole scene and hope; the good parts change too.
Long-form: 60-second explainers to 45-minute deep dives.
Short clips only.
Grounded in your own docs, README, or a link.
Guessed from a one-line prompt.
A narrated video in seconds, no long render, no black box.
Minutes per clip, then you wait.
In their words
People who made something with it.
Every quote below is from someone who built a real video here.
I had a forty-slide deck I had been reading out loud to students for two years. I pasted it in, fixed about six scenes by hand, and had the narrated video the same evening. The drawing is the part they actually comment on.
I had tried three other AI video tools and all of them gave me stock footage with a voice over the top. This is the only one that drew the diagram I described, which was the whole thing I wanted.
Not everything lands first time, I rebuilt two scenes and redrew a label. But being able to grab one box, move it, and re-render only that scene is what I could not do anywhere else.
For AI agents
Let your coding agent write the video.
Our free agent skill teaches Claude Code, Codex and Cursor to write an openCanviz video as a project file. Import it here to watch, narrate and export.
Agent skill
Available nowFree · MITA SKILL.md with the rules, a JSON schema, a Python builder that checks every file before it saves, and 22 example videos. It covers text that writes itself on, 22 scene transitions, math, charts and tables.
