DistilBook turns computer science material, lecture notes, a PDF or a typed topic, into a narrated explainer with one illustrated scene per concept or step, such as how a hash table resolves a collision or how a packet travels through a network. You review the script first. A 10 slide video takes about 15 to 25 minutes.
You start free: signing up gives you 10 credits with no credit card, a slide costs 10 credits, so the first slide of your video generates free and you can watch it in full; the rest unlocks on a paid plan. DistilBook accepts PDF, Word, images, plain text, a web article link, or a written prompt, and you approve the AI narration script before anything renders. Paid plans start at $20 per month for 230 credits, roughly 23 slides, which removes the watermark and unlocks MP4 export at up to 1440p. Narration is available in 20 languages, and the computer science explainer video maker output can carry your own logo and brand colors. Whiteboard and motion videos can be made in 16:9 landscape or in 9:16 vertical for Shorts, Reels and TikTok. Since April 2026, more than 1,400 people have made over 2,800 videos with DistilBook, most of them from PDFs.

Who is this for?
CS lecturers and teachers
Give each lecture topic a short visual explainer students can watch before class.
Tech educators and bootcamps
Explain the concept behind the code, from APIs to machine learning, in a consistent visual series.
Students and self-learners
Turn your notes into a narrated recap of a topic you need to understand, not just memorise.
Frequently asked questions
Can it show code?
It is best at explaining the concept: what an algorithm does, step by step. For line-by-line code, a screen recording of your editor is still the better tool.
Does it work for AI and machine learning topics?
Yes. Topics like neural networks, embeddings or how a transformer works suit one scene per idea.
Can I make it in another language?
Yes. Narration is available in 20 languages, chosen before you generate.
Is there a free trial?
Signup gives 10 credits with no card, enough for the first slide. Paid plans start at $20 a month, or $14 a month billed yearly.
