Memdojo turns what you're learning into flashcards, then makes sure you actually remember them. Create cards with AI from your own notes and prompts, and a proven spaced repetition scheduler retests you on them over time, so a few minutes a day is enough to keep what you learn. GENERATE HUNDREDS OF FLASHCARDS IN SECONDS Create cards easily with AI, generated from your own notes and prompts. • Paste a page of notes or just describe a topic, and get a whole deck back • Review every card before it's added — nothing lands in your deck unseen • Add images, audio, equations, tables and code to any card • Hide parts of a diagram with image occlusion and recall them one at a time • Write your own cards too, in an editor built for long sessions LEARN ANYTHING. MASTER ANYTHING. Choose from public decks or create your own, in any language or subject. • Browse public decks and folders made by other people • Publish your own, or share privately with a link • Rate and comment on what you use • Organize everything with folders, tags and favorites STUDY SMART. REMEMBER MORE. Spaced repetition retests you over time, so you never forget. • Modern spaced repetition (FSRS) decides what to review and when • Rate a card Again, Hard, Good or Easy, and the schedule adapts to you • Study reminders, so the streak doesn't depend on remembering to open the app • Daily progress, retention and workload for every deck TURN WHAT YOU LEARN INTO WHAT YOU KNOW Easily swipe through cards and practice your recall. • Swipe through cards, or have them read aloud • Bury or suspend anything you're not ready for • Pick up an interrupted session exactly where you left it • Download a deck with Plus and study it offline — it syncs when you're back GOT STUCK? LET'S TALK ABOUT IT. Talk to an AI when you get stuck, then turn the answer into flashcards. • Discuss any card with AI in the middle of a session • Ask follow-ups until it makes sense • Turn the whole conversation, or a single reply, into new cards or a card edit REGENERATE UNTIL IT CLICKS AI quick actions write mnemonics, memory palaces, or a simpler explanation. • Add a mnemonic, or build a memory palace scene • Explain it more simply, add a concrete example, or fact-check it • Rewrite a card in your own words, and regenerate until it lands ON EVERY DEVICE Your decks sync between iPhone, iPad and the web at memdojo.com. Start on your phone on the bus, finish on a laptop. WHAT'S FREE Unlimited decks, unlimited cards and the full spaced repetition scheduler — free forever, with no ads. A monthly AI allowance is included, so you can generate cards without paying anything, and you can illustrate cards from Memdojo's gallery of free-to-use pictures. MEMDOJO PLUS Upgrade when you want the AI doing more of the work, and your own media on your cards. • Plus — around 400 AI generations a month, a faster model, your own photos, diagrams and audio, image occlusion, and decks you can download to study offline. $5.99/month or $34.99/year. Nothing about studying is ever paywalled. Decks, cards, the scheduler and stats are the same on every plan.

Verdict
The clearest difference is ads: Memdojo at none against Umi's shown. Umi's advantage is chart position (#191 vs unranked) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.
