Simple plans for watching, and for lessons built to order

We turn a single problem into a short animated video where a student persona and a teacher persona work through it together — with confusion, a mistake, a correction, and a breakthrough. You watch someone learn rather than being lectured at.

Today: Chemistry (ten domains including stoichiometry, acid & base, gas laws, and equilibrium), Algebra 1 (linear equations, systems, quadratics, functions, polynomials & radicals, and word problems), Algebra 2 (thirteen domains covering complex numbers, logarithms, exponentials, polynomials, and rational functions), Geometry (twelve domains spanning foundations, triangles, quadrilaterals, circles, similarity, transformations, coordinate geometry, and measurement), and Nursing (dosage and IV calculations). More subjects are on the roadmap, each added as a bounded set of problem shapes.

Dosage calculations and IV calculations — working out a dose from a patient's weight, converting that dose to a volume to draw up, and setting an infusion rate. These are the dosage topics from GOB (General, Organic & Biological chemistry), the course nursing majors take. The general-chemistry topics that course also covers are on the site under Chemistry. The organic and biochemistry halves are about drawing molecular structures rather than reaching a number, and are not covered. The lessons teach the calculation; they are not clinical guidance and no dose shown should be used to treat a patient.

Problems are matched to canonical shapes with defined reasoning, and technical notation is converted so it's spoken correctly. Every lesson can be reviewed before it's published, and pronunciation or content issues can be flagged and re-rendered — vetting is part of the workflow, not an afterthought.

No — you don't touch any software. You send the problems you want covered, in whatever form you already have them: a worksheet, a slide deck, a photo of your own handwriting. We build the lessons, check each one against your own answer and method, and send you finished files. There is no editor to learn, no timeline, and nothing to install.

1080p long-form MP4s and vertical shorts from the same lesson. Every lesson also comes with a persona-driven title, description, and hashtags ready for publishing. Packaging a lesson for a course platform additionally generates a WebVTT caption file and a scored knowledge check.

Yes — that is the case it is built for. Asynchronous means the learner works alone, at a time they choose, with nobody available to ask. Every lesson is a conversation in which the on-screen student asks the question the viewer was about to ask, so the common confusion is handled without a teacher present. A packaged lesson ships as files rather than as a page on our site: a 1080p MP4, a WebVTT caption file, and a scored knowledge check whose wrong answers come from more than 600 hand-written notes on the errors learners really make. For a course that has to record completion, lessons package as a SCORM zip — the format a Learning Management System imports — which reports a completion and a score, and still plays on its own outside a platform so you can preview it first. The full picture, including what it does not do, is here.

Yes, if your platform accepts SCORM 1.2 — nearly all of them do. A LessonSlate module has been imported into SCORM Cloud, the conformance service LMS vendors test their own products against, and run end to end: it played, it scored, and it reported a completion, with no errors. That is the same package your platform receives.

Platforms still differ at the edges, so if you are planning a rollout, tell us which one you use and we will confirm against it first. The package also plays on its own outside an LMS, so you can preview a module before importing anything.

Yes — that's exactly what the Institution & publisher plan is for. Each subject keeps one consistent house voice and notation style, so a full curriculum library feels coherent. Reach out to discuss licensing and distribution.

Right now lessons are being produced at no cost for a handful of instructors, while we work out what genuinely helps in a classroom. When there is a price it will be per course library rather than per video, and it will be a small fraction of what a studio charges for a single animated minute — a ten-lesson set is roughly fifty minutes of finished animated instruction, which is six figures at agency rates.

If you need a number to put in a budget request, ask and you'll get one for your specific scope rather than a range. Let's find out whether the lessons are any good first.

No. The Viewer tier is free and will stay free. Creator and Institution pricing is deliberately not published yet — join the Creator waitlist and we'll share plans, and any early-access offers, before they go live.

More subjects and domains, and continued refinement of voices and animation. Because LessonSlate scales by shape rather than by hand-authoring, each new discipline expands coverage without rebuilding the engine.
