In their own words
Brainscape
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.
Cogni
Cogni combines study notes, AI-generated flashcards and spaced-repetition reviews. It can make editable question-and-answer or cloze cards from text, PDFs, web pages and photos of notes. Notes support headings, bold, highlights, lists and images, and cards created from a note remain linked to it. During review, learners rate cards Again, Hard, Medium or Easy; Cogni adjusts each card’s review schedule based on those ratings. Progress views show daily streaks, retention by deck, cards due tomorrow and a forecast of upcoming weeks. Cogni is available on the web and in Android and iOS apps. The mobile apps support offline review and sync reviews across web and mobile when the device reconnects. The mobile app can import Anki .apkg decks, including subdecks, cloze cards and media, but does not transfer review history. Free access includes notes, spaced repetition, device sync and Anki import, subject to a daily review limit. Cogni says it does not sell study content or personal information, use study content for third-party ads, or use notes and cards to train a Cogni model.
