Rechi —
personal dictionary that remembers for you

Rechi is a personal vocabulary that tells you which words to review today. You learn only your own words — from a course, a book, a TV series or a chat — and Rechi takes care of the review schedule.

After a break, Rechi rebuilds your queue on its own: it shows the words you have most likely forgotten first and sets a realistic pace, without a pile of hundreds of overdue reviews. You don’t have to start over, remember where you stopped or decide what to review. And if you still remember a word after a long pause, its next interval grows more than usual, because the word has clearly stuck.

Spaced repetition is a memorisation method in which you review a word at gradually increasing intervals, shortly before you would forget it. This moves the word into long-term memory and takes far less time than cramming.

Rechi uses an improved SM-2 algorithm — the classic spaced repetition algorithm with our own refinements. The interval before a word comes back depends on how easily you recalled it and on how you actually study, for example on breaks and your current workload.

Rechi is powerful on the inside and effortless on the outside. Unlike Anki, there is nothing to set up: Rechi decides which words to review and when. After a break, it rebuilds your queue on its own, so you never have to start over. Adding a word is easy and takes just a few seconds, and we keep looking for ways to make it even easier and faster. For every word you can save the phrase where you met it. Words are learned in both directions, each with its own statistics. And the app installs on your phone without the App Store or Google Play. The less effort learning takes, the easier it is to stick with it — because the best language-learning app is the one you use.

You can learn words in any language with Rechi, because you enter the word and its translation yourself — any language pair works. English, Serbian, German, Spanish, Chinese or any other language works the same way. The app interface is available in English, Russian and Serbian.

Yes, Rechi works on iPhone and Android: it is a web app (PWA) that installs on your home screen without the App Store or Google Play. On iPhone, open app.rechi.app in Safari and choose Share → Add to Home Screen. On Android, open it in Chrome and choose Install app from the menu.

Yes, Rechi opens on any device with a browser, but you can study on only one device at a time. Your vocabulary and progress are tied to your account, so you can, for example, add words on your computer and review them on your phone on the go.

5–10 minutes a day is enough. Consistency matters more than duration: a short daily session does more than an hour once a week. To avoid overload, Rechi shows at most 20 new words and 180 reviews a day in each direction.

Yes, Rechi imports words from CSV and TXT files where the word, its translation and, optionally, context with its translation are separated by tabs. You can upload up to 3,000 words at a time. An Anki deck or a Quizlet set can be moved over by exporting it as a tab-separated text file.

Yes, you can save the phrase where you met each word, along with its translation. A word seen in a real example is remembered faster than one learned in isolation.

Yes, every word can be practised in two directions: from the foreign word to its translation and from the translation back to the word. Each direction has separate statistics, and you switch between them in the settings.

The phonetic association method is a way to remember a foreign word through a similar-sounding word in your native language and a vivid image. For example, the Russian word кот [kot] means “cat” and sounds like “coat”: picture a fluffy cat strutting through the snow in a tiny winter coat. Rechi’s Help section has a detailed guide to the method.

Yes, you can start using Rechi for free. The free plan has enough features to understand whether Rechi is right for you.

Yes, we are preparing a dedicated programme for teachers and language schools: students learn words from your curriculum, and you see their progress. You can apply on the For teachers page.
