Cogni vs Mochi

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.

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. Pro adds synchronization of cards and notes across devices, 10 GB of cloud storage for synced materials and attachments, and the ability to publish decks by link or in the deck library. 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. Pro costs $5 per month when billed annually; monthly Pro is also listed at $5 per month. Documentation and forum support are included, with email support on Pro. After downgrading, cards and notes remain usable offline, but Pro features stop at the billing period’s end.
