Watch your explainer video draw itself a minute from now

Chasca, also known as Chasca AI, is an AI whiteboard video generator. Give it a prompt, a document, a recording or a link, and it writes the script, storyboards every scene and draws each one stroke by stroke in time with the narration, usually in under a minute. You get a narrated explainer to download as an MP4 with subtitles or share with a link, and you can change one thing at a time, such as the subtitles, the style or the music.

A short video that explains one idea by drawing it while a narrator talks it through. Each picture appears at the moment it is named, which is what makes the format easy to follow: in controlled studies, diagrams drawn in step with the narration were remembered better than finished ones. More on the format.

Sign up and make 2 videos, up to a minute each, with the whole product: the script, the drawing and the narration, every voice and every style. Free videos carry a small “Made with Chasca” mark in the corner. No card, no trial clock.

Most videos are ready in under a minute from the moment you press generate. Long videos take longer, roughly as long as they run. Changing the subtitles, style or music keeps the script and the narration, so only the drawing is done again.

Paid plans start at $9.99 a month for 30 rendered minutes, billed monthly. Rendered minutes are the only thing we meter; seats and shared workspaces are unlimited. See every plan.

Yes. Your first 2 videos are free, up to 1 minute each, watermarked. No card required. You get the full product, every voice and every style, so you can judge it on a real video about your own topic.

A one-line prompt, your own script, or a source: PDF, Word, PowerPoint, Markdown or plain text; an image, such as a photo of a worksheet, a slide or your notes; audio (MP3, WAV, M4A and more); video (MP4, MOV, WebM); or a link to an article. Chasca reads the whole thing, every line and table of an image included, finds the idea worth explaining and writes the script from your material, so the numbers in the video match the numbers in the document. A script you wrote is spoken word for word, and a recording can narrate the video itself: tick Use as the narration.

Yes. Paste your script and the narrator speaks it exactly as written, scene by scene, with nothing added or dropped. Put the words you want on screen in quotes, such as a title card or a closing “Follow for more”, and they are drawn on the board exactly as given. Your facts and numbers stay as you wrote them. How it works.

Yes. Pick a Drawing hand in the Look tab, or ask for one in your request: a real hand follows the pen as every line and word is drawn, the classic whiteboard animation look. There are five hands, a marker in a light, medium or dark skin tone, a pencil and a sketched hand, on every plan and board style, and you can switch the hand on or off on a finished video for free. More on the drawing hand.

No. Chasca makes narrated whiteboard videos: drawings, words and diagrams appear on a board as a voice explains. It can’t make 3D, realistic or cinematic footage, characters who act out a scene, speak or move, avatars or lip sync, sound effects or silent videos. If your request asks for one of these, Chasca says so before it makes anything: nothing is charged, and changing the request doesn’t use up a free video.

30 expressive narrators, led by Sulafat, the default, and every one of them speaks all 79 languages in the same voice, so a course keeps one narrator from English to Japanese. They perform with feeling: each scene gets its own tone, and the script can ask for a whisper, a laugh or a pause. Leda is a bright voice for younger audiences. You can also narrate in your own voice: read out loud for about a minute and Chasca makes a custom voice from it, on every plan. Browse the voices.

Yes. Attach the recording on the Create page and tick Use as the narration: the video keeps every word as you said it, and the board draws in time with it. Recordings can run up to 1 minute on Free and up to 30 minutes on paid plans. How it works.

Yes, on Pro, Max, Team and Enterprise. In Settings, Branding, add your logo, colors and font, and a credit line of up to 80 characters, such as an author or copyright line, shown small on every scene. More on branding.

From 30 seconds to 30:00 on paid plans, and up to 1:00 on Free, or leave it on Auto. Attention falls off sharply after about six minutes, so past six Chasca tells the video in chapters, each with its own opening and a short recap. On Auto, it asks before making a video longer than ten minutes. Here is the research.

Free videos run up to a minute. When your request needs more, the free video makes its first part exactly as you asked, your first scenes in your words, and shows what’s still to come, with Unlock them with a plan. On a paid plan, Make the whole video makes all of it in one go, up to 30 minutes. See the plans.

Yes, from day one: a REST API, a TypeScript SDK and CLI, and an MCP server, so Claude, Cursor or any MCP client can make and change videos for you. API access comes with Plus and above, and videos made with an API key use plan minutes at 2x; the connector for Claude and other assistants works on every plan and counts like the app. Read the docs.

Chasca is built by a small, independent team that got tired of watching good ideas get lost in long documents. The drawing on this page is the real thing: the same engine that renders your final MP4.
