Engaging lessons, without an animation team
Teachers, tutors, and curriculum designers get scalable instructional video that models real thinking — built from the problems you already teach.
The AI is in the authoring, not in the classroom
Districts are increasingly restricting AI that students interact with directly — chatbots, tutors, companion apps and monitoring tools. Those rules are written about software a child talks to. LessonSlate is not that, and the distinction is worth having in writing before anyone asks you for it.
By the time a lesson reaches a learner it is a video file, a caption file and a scored quiz. Nothing runs during playback. There is no prompt box, no account, no login, and no student data of any kind is sent to us. You review the lesson, then you assign it — exactly as you would a worked example you wrote on the board yourself.
- No student-facing model — nothing for a learner to chat with, in any subject
- No student data collected — the LMS package makes no outbound calls; completion and score stay in your gradebook
- A person approves every lesson — after an automatic checker recomputes the arithmetic and refuses to publish a lesson that does not add up
- Quiz distractors written by people — 661 hand-recorded learner mistakes, not model-invented filler
- AI authorship disclosed — plainly, on the lesson and on the site
Where it fits in your week
Every one of these moments is asynchronous — the learner is working through it without you standing next to them. Drop a LessonSlate video into the places where a worked example does the most good.
Flipped classroom
Assign the lesson as homework so class time is freed for practice, questions, and the harder conversations.
Pre-teaching
Give struggling learners a gentle first exposure before the concept lands in a whole-class setting — lowering anxiety, raising confidence.
Remediation & catch-up
Point a student to the exact problem shape they're stuck on, and let them re-watch the reasoning as many times as they need.
Sub & absence plans
A consistent, patient teacher on screen means learning continues even when you can't be in the room.
Mistakes on screen so they're not a risk in the room
When a student watches the on-screen learner get something wrong and recover, they absorb the correction without ever feeling exposed. That psychological safety is the whole point — and it's especially powerful for learners carrying maths or science anxiety.
"Students learn best when they see confusion modelled and watch mistakes corrected in real time."
- Consistent, patient explanations every single time
- Notation spoken correctly — real chemistry and algebra
- Colour-coded reasoning that's easy to follow and re-teach
- Re-watchable at the learner's own pace
- Aligned to the exact problem types you assign
What a lesson has to carry when you are not there
Asynchronous instruction is the part of teaching that leaves the room with the student. Four things have to travel with it, and each of them ships with every render.
The question gets asked for them
At home there is no hand to raise. The on-screen student hesitates, guesses wrong and asks it instead — and the lesson is built around the mistakes learners actually make on that problem type, so the one they were about to make is usually the one on screen.
Captions on a real track
Packaging a lesson generates a WebVTT subtitle file, timed off the same clock as the audio so it cannot drift. It rides on a real caption track rather than being burned into the picture, so a learner can turn it on. Nobody working alone can ask for an accommodation, so it is there by default.
A check that says whether it landed
A scored set of questions attached to the lesson. The wrong options are not invented — they come from more than 600 hand-written notes recording the errors learners really make, so a wrong answer tells you which misunderstanding they are carrying, not just that they missed one.
It records who did it
Lessons package as a SCORM zip — the format a Learning Management System accepts. Your platform gets a completion and a score per learner, so you are not chasing it by hand. The package also runs on its own outside an LMS, so you can preview it before importing.
