Watch it explain itself.
Most AI video is built for cinematic clips. Chalk is built for useful videos that teach and explain.
One line in — a narrated, hand-drawn whiteboard video out: a real script, clean scene diagrams, and every icon drawn as it’s spoken.
Every icon above comes from Chalk’s own image-model icon library — one style, hundreds of concepts, with new concepts added when needed.
How it works
Type one line
“Explain how credit scores work.” That’s the whole brief — no timeline, no editor, no assets to hunt down.
Agents write & design
A scriptwriter drafts a real narrative, an editor makes every sentence drawable, and a designer lays out each scene as a clean diagram.
Watch it stream in
Progressive playback can begin while rendering continues, and the board reveals each idea in sync with the narration.

Prompt: “How does the water cycle work?” Chalk created the script, scenes, narration, and icons.
Read the water-cycle video transcript
Water on Earth
Earth holds a fixed amount of water. Ninety-seven percent of this water is salty ocean water. Only three percent of Earth's water is fresh water. Only one percent of this fresh water is accessible on the surface.
Evaporation
Step one begins when the sun heats the ocean surface. Liquid water absorbs this heat and transforms into invisible gas. Eighty percent of all water vapor comes from our oceans. This warm gas rises high into the sky.
Transpiration
Step two is transpiration, where plants release water vapor. First, roots pull liquid water up from the soil. Then, leaves release this water through tiny pores. One single oak tree releases forty thousand gallons of vapor every year.
Condensation
Step three is condensation, where rising vapor cools down. The temperature drops three point five degrees Fahrenheit for every thousand feet. This cold air forces the rising vapor to clump together. The vapor turns into liquid droplets to form clouds.
Precipitation
Step four is precipitation, when clouds get too heavy with water. Gravity pulls this stored water back down to the ground. Above thirty-two degrees Fahrenheit, water falls as liquid rain. Below thirty-two degrees Fahrenheit, water freezes into snow.
Collection
Step five is collection, which divides water into two main paths. Path one is runoff, where water slides into rivers. Path two is infiltration, where water sinks deep into the soil. Both paths eventually empty back into the ocean.
Recap
Let us review the five steps of the water cycle. First, water evaporates from oceans and transpires from plants. Second, the rising vapor cools and condenses into clouds. Third, precipitation falls and collection returns it to the sea. This same water has recycled for four billion years.
Built to explain
Scripts that teach
A hook, a guiding analogy, real numbers put on screen — not a bullet list read aloud.
A hand-drawn icon library of its own
Every icon comes from Chalk’s style-locked library, and missing concepts can be generated, checked, and added when needed.
Deterministic layout engine
Flows, comparisons, cycles, and timelines are placed with geometry, collision repair, and automated quality checks.
Speech-timed draw-on
Icons wipe in outline-then-fill from measured narration beats. The narration is the storyboard.
Live playback
An HLS stream starts while the render is still running — no waiting for the full video.
Reliable by construction
Checkpointed jobs, resumable renders, and a watchdog that fails loudly instead of hanging.
