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.
diStudero
diStudero is a web-based study aid that turns uploaded material into AI-generated learning resources. It accepts PDFs, DOCX and PPTX files, photos, plain text and links, including scanned notes, and can produce flashcards, quizzes, notes, podcasts and infographics. Its tools also include mock exams, games, mind maps, assistants, timers and progress statistics. Generated flashcards can be edited, extended, printed or shared; the FSRS algorithm uses card performance to schedule reviews. A Chrome extension can analyze selected webpage text, translate in 15 languages, write with AI and import Google Docs documents up to 50,000 characters. On iPhone and Android, it installs from a browser as a progressive web app. The free tier allows 5 folders, 5 MB of storage, one file per upload, 10 AI flashcards and 10 quiz questions per day, plus 10 chat messages per day. Pro Monthly is €11.99 a month and includes 20 credits per month; a 5-day trial is listed.
