Change it in a click
Turn on subtitles for your class, switch to the Chalkboard style or add music, free. The words and drawings stay exactly as they were.
For teachers and students
The whiteboard, without the chalk dust.
Type a topic or drop in your lesson notes. Chasca makes a short, narrated video that draws itself while it explains, and ends by asking your class a question.
Why it works in class
Designed around how people learn.
Short parts, even in a long lesson
Videos run from 30 seconds to 30:00. Past six minutes a lesson is told in chapters, each ending in a recap, so every part stays short enough to follow.
Lessons end with a question
Every lesson closes with a retrieval question and a pause to think before the recap. Remembering is where the learning sticks.
Made for younger learners
Leda, a bright young narrator, and the thick, cheerful Crayon style make K–8 topics feel like a friend explaining.
Crayon style and Leda
A friend explaining, not a lecture.
The Crayon style draws in thick, bright strokes that younger students love. Pair it with Leda, a bright, playful narrator who sounds like a slightly older kid explaining to younger ones, in any language.
Prefer something calmer for older students? Switch to Chalkboard or Pencil, and pick any of the 30 narrators. Same script, redrawn in seconds.
In the classroom
Four ways teachers use it.
-
Flip a lesson

-
Revise before a test
One short video per topic, each ending with a question to answer from memory.
-
Explain it back
Students make a video on a topic, then check every scene against their notes.
-
Reach every family
Send the same lesson home in any of 79 languages, in the same voice.
Quiz and math lessons
Every answer choice stays on the board.
Paste a question with its answer choices and say which one is right. The video keeps the question and every choice on the board, and circles the right answer in the color you ask for. Teaching in Arabic? Equations in Arabic-Indic digits are written right to left, the way your students learn them.
See Arabic math lessonsYes. A great exercise is to have students explain a topic back: they write the prompt, check each scene against their notes, and if something is wrong, improve the prompt and make the video again. Accounts are for ages 13 and up; for younger classes, the teacher runs the account and shares the videos.
Every video has a share link you can switch on or off, and you can download the MP4 with SRT and VTT subtitles for your LMS or a slide deck.
Chasca narrates in 79 languages, and every narrator keeps the same voice across all of them, which helps in multilingual classrooms and language departments.

Yes, two ways. Record a custom voice by reading for about a minute, and it reads any new lesson. Or attach a recording of you teaching and tick Use as the narration, and the board draws along with your words. Custom voices and your own voiceover explain both.
