Re ReasonBoard
Blackboard tutor

Lessons that draw themselves, speak your language, and work with no network.

Drop in notes, a PDF, or a photo. ReasonBoard writes the lesson out by hand on a chalkboard and teaches it aloud — step by step, with quizzes and a “raise your hand” button, in 13 languages. A teacher checks every lesson before the class sees it, and once it’s downloaded it plays with no connection at all.

Everything a tutor does — on one board

Narrated chalkboard

A teacher writes each step by hand and explains it aloud in a natural studio voice, synced to the writing.

Raise your hand

Pause anytime and ask. Your tutor sketches the answer on the board, then picks up exactly where it left off.

Quizzes & mastery

Every lesson ends with a quiz. Day streaks, completions and mastery are tracked for each student.

Multilingual lessons

Generates lessons in 13 languages, including Swahili, Afaan Oromo, Amharic, Hausa and Yoruba. Narration is most natural in English today; African-language voices are still improving.

Classes & assignments

Teachers create a class, share a join code, assign lessons, and watch every student’s progress roll in.

Math, figures & offline

Renders formulas, plots graphs, pins & labels your figures — and installs as an app that runs with no network.
