What is an AI educational video
The lesson plan, production-ready.
An AI educational video is a long-form YouTube lesson — voiceover, animated visuals, diagrams, chapter markers — generated from a prompt, a syllabus or a transcript. Built for teachers, coaches, professors, edu-brands and side-channels that want to turn knowledge into a daily upload.
Lesson-aware AI
Postcrest scripts in a teacher's voice: hook, explain, recap. Optimized for retention.
Auto chapter markers
Every lesson ships with YouTube chapter markers, ready for SEO and skim-watchers.
Diagrams + visuals
Generate diagrams, animations, photo b-roll — matched to the line being spoken.
Captions + transcripts
Word-level captions and a full transcript every video. Great for SEO and accessibility.
Why educators switch
Teach more. Re-record nothing.
The old YouTube way
Re-recording the same lesson
Every cohort, every season, every typo. You record "the water cycle" for the fifth time and your soul leaves your body.
Diagrams take hours
Drawing diagrams, animating arrows, exporting to MP4, syncing to your voiceover — five hours per lesson.
Stuck in one language
Your French students want a French version. Your Spanish students want one too. You don't have time.
No chapter markers
YouTube viewers skip around. Without chapter markers your retention tanks and your search ranking suffers.

Curriculum-aware AI
Bring your syllabus, lesson plan or transcript. Postcrest respects it — facts, terminology, examples — and structures the video around it.
Diagrams + labelled animations
Process flows, anatomical labels, equation walkthroughs — Postcrest generates them per concept and animates them to the narration.
Chapter markers automatic
Every lesson exports with YouTube chapter markers. Retention up, time-on-page up, search ranking up — at no extra effort.
Translate + re-narrate
One lesson → 29 languages with consistent pacing and prosody. Build a multilingual edu channel from a single script.
Captions + transcript export
Word-level captions and a full transcript shipped with every video — great for accessibility and lesson summaries.
Optional AI teacher
Use a faceless narrator, or train an AI teacher character to host every lesson. Same face, same voice, every video — students recognise them like a real teacher.
