In their own words
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.
StudyGlen
StudyGlen turns study materials into AI quizzes, flashcards, educational comics, and live quiz competitions. It accepts PDFs, text, images, handwritten notes, YouTube links, and Anki decks; quiz creation can use image OCR and YouTube captions.

Quiz generation can also be tried without an account, with five free questions and no card required. Paid packs are one-time purchases starting at $4.99; the Mini Pack has 10 study credits, and each credit generates one complete quiz or deck. Quizzes can be exported to PDF, Word, CSV, Anki, or QTI.
