Built by someone who had to learn the hard way.

I've been a career linguist for over 20 years. That means sitting down and committing massive amounts of vocabulary in one setting — not casually picking up a few words a day, but grinding through hundreds of terms under real pressure. Most popular tools were too gamified. They beg for your attention, reward streaks, and treat studying like a mobile game. The tools that weren't gamified were too technical — dense configuration, steep learning curves, and setups that felt like a project before you ever studied a single card. I just wanted to sit down and learn. So I built something that gets out of the way.

Because typing works. I firmly believe that physically typing a definition — not just recognizing it — is one of the fastest ways to commit vocabulary to memory. Writing by hand is even better for retention, but typing is fast enough to keep momentum. The act of producing the answer, rather than passively confirming you recognized it, creates a reinforcement loop. You get through material quickly, and it actually sticks.

Speed matters. When you're in a flow state with a deck, the last thing you want to do is reach for a mouse. Every action in a drill session — submitting an answer, overriding a result, editing a card, skipping — is reachable from the keyboard. You should be able to get through an entire session without touching the mouse once. That's intentional.

On mobile, the same fast-moving philosophy was built into a swipe system. Swipe to mark correct, swipe to flag, move through cards quickly without tapping around menus. It's not identical to keyboard drilling, but the principle is the same: keep the pace up, keep the friction low. Keyboard is still better for memory retention in our view, but mobile should feel just as purposeful.

Duolingo is great for casual exposure, but it's engineered to keep you coming back through notifications, streaks, and gamification — not to get you fluent fast. For serious vocabulary acquisition, that model gets in the way. There are no treasure chests here, no streak penalties, no leaderboards. Just decks, drills, and the feedback loop of typing until it sticks.

Anki is powerful, but it asks a lot of you before you can even start. Custom note types, sync configuration, a plugin ecosystem, and a UI that hasn't changed much in years. Mnemio is designed to get you from content to drilling in minutes, with sensible defaults and real structure — courses, folders, deck organization — without requiring you to learn the tool before you can use the tool.

No. The system works for any subject that benefits from definition-style recall — medical terminology, law, history, certifications, anything. Language learning is where it was built and tested, but the drill format is general enough to handle whatever you need to memorize.

Typing is the core, but not the only channel. Every card supports audio playback, so you hear the word as you study it. Neural text-to-speech (Pro) gives you natural pronunciation rather than robotic output. The combination of reading, typing, and hearing the same content at once engages more of the learning process than any single method alone — without turning it into an overstimulating experience.

Yes, and we mean it. This was built by someone who uses it seriously, and we have no interest in building features for the sake of a marketing page. If something is missing, confusing, or broken, we want to know. User input has shaped nearly everything in the current build, and that is not going to change.

Yes. The free tier includes unlimited manual decks, CSV import and export, full session customization, keyboard-first drilling, and browser audio. AI deck generation is capped at 3 lifetime uses on the free plan. Pro unlocks unlimited AI, neural TTS, spaced repetition controls, and offline mobile.

Yes. CSV import is available on all plans. You can also import directly from Anki — just export your deck as an .apkg file and bring it straight in. If you have content in any other app, a CSV export will work too.

Yes, at any time from account settings. You keep Pro access through the end of your billing period. Your decks and data are never deleted.
