Brisk Teaching

A browser extension across the tools teachers already use

We publish a full Four-Mismatches fit assessment for the student-facing exam tools first. For this one, the facts below are what we have verified — run the Four Mismatches Test on it yourself for your own students.

Independence: Addestra builds learning products too (MathsTutor, TinkerWell). We never review or score our own, and no tool pays to be listed or to rank higher — how we assess fit.

What it does

What the AI actually does — A Chrome-extension LLM that generates feedback, rubrics and levelled text in-place, and detects AI-written student work via edit-history inspection.

Why it was built — Automate teachers' time-intensive tasks inside the tools they already use (Google Docs/Slides, the browser).
