LearnFastAI Finds the First Wrong Line in Your Homework
An AI study tool that checks maths and STEM working, identifies the first mistake, names the missed rule, and stops short of completing the answer.
Field notes
The product analyzes a student’s captured working rather than treating the exercise as a blank problem: its example stops at the missing inner derivative in a chain-rule calculation and asks the student to supply it. The desktop interface is presented as an overlay for OneNote, PDFs, Word, and browser assignments, with four keyboard commands for checking, hinting, explaining, and asking. The homepage names Windows 10 and 11 and shows calculus and classical mechanics examples.
