A studio for lessons that teach themselves
Everything you need to turn a problem into a polished, watchable lesson — the pedagogy, the animation, and the production, in one pipeline.
Socratic dialogue engine
Two AI personas hold a real teaching conversation — attempts, mistakes, guiding questions, and breakthroughs — instead of a scripted monologue.
Animated Thinking Canvas
A clean digital whiteboard draws each step in sync with the speech: units cancel, equations balance, grids and parabolas come alive.
Natural, distinct voices
Expressive synthesized speech gives the student and teacher their own voice, with human pauses, hesitations, and affirmations.
Notation-aware speech
Formulas, subscripts, ionic charges, exponents, and units are spoken the way an expert would say them — not read out character by character.
Publish-ready metadata
Every render ships with a persona-driven title, description, and hashtags, formatted for YouTube out of the box.
Creator controls
Tune student confidence and error rate, teacher pacing and style, visual density, avatar presence, and transcript visibility.
Daily production pipeline
Batch multiple problems a day through the full flow and upload them for review — a repeatable engine, not a one-off tool.
Multiple output formats
Chaptered long-form MP4s and vertical shorts from the same lesson, at cinema-standard 1080p / 24 fps.
Built-in vetting
Review lessons before they go public, flag pronunciation issues, and re-render — quality control is part of the flow.
Dial in the lesson
- Student: confidence, curiosity, error rate, persistence
- Teacher: patience, explanation depth, Socratic vs. direct
- Visuals: light, standard, or dense
- Presence: avatar anchors on or off
- Transcript: visible or hidden
One problem, several watchable variants
Because you control the personas and the pacing, a single problem can become a gentle, slow walk-through for a struggling learner or a brisk, confident recap for revision — without rewriting anything.
The reasoning stays deterministic; only the delivery changes.
17 domains, 100+ problem shapes
LessonSlate scales by mapping every problem to a finite set of canonical shapes — so new problems need new data, not new code.

Personas per subject
Chemistry is taught by Sam & Dr. Chen. Algebra 1 is taught by Maya & Ms. Rivera. Each subject keeps its own voice, notation handling, and branding — no cross-contamination.
Coverage is actively growing. Because each new discipline adds a bounded set of shapes rather than endless bespoke lessons, subjects come online quickly:
