Brainscape vs Mochi

Brainscape is a flashcard study platform that uses AI to create cards and spaced repetition to organize review. Learners rate their confidence on a 1–5 scale, and the platform uses those ratings to adjust when cards return. AI can turn PDFs, documents, and presentations into flashcards. Cards can contain formatted text, images, sounds, and animated GIFs; users can invite students or instructors to contribute edits or feedback. Its library includes user-created and expert-certified cards across exams, languages, and professional certifications. Integrations support work with apps and tools, while the Ghost API can be used to create custom integrations. Brainscape is available on web, iOS, and Android. The individual Basic plan is free and includes 2,500 pre-loaded flashcards; the listed Pro (Individual) price is $7.99 a month, billed yearly. Enterprise group licensing has custom pricing. Brainscape says its AI features are opt-in and only raw study materials go to AI providers, which do not use Brainscape data to train their models. It also says it does not sell personal data or run personalized ads.

Mochi is a flashcard and note-taking app for making study materials with Markdown and reviewing them through spaced repetition. It is available on Mac, Windows, Linux, iOS and Android. The Free plan is free forever, does not require sign-up, and includes unlimited cards and decks, import and export, and unlimited offline use. Data stays on the user’s device and syncs when online.

It also includes AI completion, AI integration and language services subject to monthly limits. Limits reset at the start of each calendar month, unused amounts do not carry over, and a service stops when its limit is reached.

After downgrading, cards and notes remain usable offline, but Pro features stop at the billing period’s end.
