Cogni vs Lernoa

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.

Lernoa is a study application for turning documents or topics into structured courses and for building, importing, and studying flashcard decks. Upload a PDF or DOCX, or enter a topic, and it can create chapters, quizzes, and a final exam. AI features include summaries, flashcards, quizzes, and narrated audio with read-along highlighting. Course and document chat answers are based on the supplied material and include source citations, within a small daily question allowance. Review uses an Anki-style SM-2 scheduler and retires cards recalled reliably over long intervals. Anki and CSV decks can be imported, decks exported as CSV, and courses moved in Markdown or text formats. Lernoa connects to Claude, ChatGPT, and other Model Context Protocol assistants; generation uses credits. The first chapter of each course is free, while later chapters cost one credit each. It runs on Android, iOS, and the web, with a free plan and no free trial.
