Sketchie is built on the published science of how people learn from video. Not as a marketing line. As hard rules in the generator.
Lesson notes, a chapter PDF, a lab procedure, a study guide. Sketchie draws it out stroke by stroke, narrated, timed to the words.
Spotted an error during first period? Open the scene, correct it, re-render in seconds. Teach the fixed version second period.
The engagement research is unambiguous: attention collapses after 6 minutes. Sketchie caps videos at 6 minutes and turns a full unit into a chaptered series. 30-second length steps mean a bell-ringer clip is actually 30 seconds.
A retrieval prompt appears, the video pauses, then a one-line recap. Retrieval practice is one of the most robust effects in learning science, and Sketchie builds it into every single video automatically.
Sketchie’s voice library includes voices designed for the audience, not just adult narrator defaults. The kid-explains-to-kids voice narrates like a slightly older student walking a younger one through it. Peer-style explanation, on demand, in every video you make for young learners.
And if you want your own voice in your students’ videos, paste an ElevenLabs or Fish Audio voice ID and every explainer sounds like you.
Feed Sketchie the chapter, get a drawn, narrated explainer, then quiz yourself on the retrieval question at the end. The trial gives you your first 3 videos with the full product, so the topics that refuse to make sense from the textbook cost you nothing to test. It does take a card at signup, and you pay nothing if you cancel before the trial ends.
We are careful with this claim, so here is exactly what it means. We reviewed the published research on learning from video: progressive drawing versus static diagrams, segmenting, signaling, the 6-minute engagement cliff, seductive details, narrative structure, retrieval practice. We turned the findings that survived scrutiny into numeric rules the generator must obey, and we test every video against them automatically. The full spec, with citations and the things we could NOT verify clearly marked, is public.
The trial covers your first 3 videos with everything included, editor and all. For a single classroom, the Plus plan is the usual home. If you are a school or district that needs volume, email us. A human answers, there is no sales call gate, and we will quote you a number in the first reply.
