StudyFetch chats with your notes. Synapsi proves you learned them.
StudyFetch's tutor is grounded in your materials, like Synapsi's. The difference is measured mastery: Synapsi's Feynman teach-back is judged by an AI and your concepts advance only on real study signals. Plus a free start with no card.

StudyFetch and Synapsi both ground their tutor in your own materials. Where StudyFetch stops at chat, Synapsi measures whether you learned the thing: an AI-judged teach-back, a concept-mastery journey, and FSRS spaced repetition.
Use StudyFetch for a grounded chat tutor. Use Synapsi when you need proof of learning, not just a conversation.
Prove you actually learned it.
