Teachfy
A study app that made flashcards from your own material. Discontinued, gladly.
You gave Teachfy your own material, a PDF or text you typed in, and it generated flashcards and questions from it using the ChatGPT API.
The idea was to take friction out of studying. Turning your notes into something you can study from takes time, and the app did that step for you.
How it was built
It ran on mobile and on the web. The mobile app was React Native, the web app was React, and the backend was Laravel and Node.js.
A good part of the work was getting text out of PDFs reliably enough to make useful cards from it. The rest was fitting the AI into an actual study workflow.
Why I let it go
Teachfy is discontinued, and I'm glad to say why. Google's NotebookLM later built the same idea, flashcards and quizzes generated from your own sources, and did it much better. It also put the idea inside a product where it makes more sense.
I have no problem with that. They did great work. Knowing when someone else has solved your problem better than you did is part of building with intent.
