Learn from courses your own mistakes — right where you make them.
Reading articles and watching videos is easy. Writing without the same old mistakes is the hard part. YabLab lives in your browser and on your Mac, turns your day into exercises — and you can review them from your phone.
Videos, blogs, emails, chats — you don’t change a thing about your day.
Slips become explained corrections in your error profile. New words become flashcards.
Spaced repetition brings each mistake back right before you’d forget it — until it’s gone.
Mastered, fading, or at risk — every rule has a status. Wins get celebrated; a slipping rule gets a quick rescue drill.
YabLab tracks more than study time: which mistakes keep coming back, which rules are improving, and how the quality of your language changes over time.
Underlines a slip, explains it in your language and fixes it — in the browser and on a Mac.
Select a word on any website for its translation, meaning and examples. Works on a Mac too: ⇧⌘Y in any app.
Words come back as flashcards just as you start to forget them.
Translate it, and it’s a card.

No chatbot tab, no lost context.

On any site — even on your Mac.

No. Checking is off until you explicitly turn it on, and you can pause it or disable it per site in one click. Text is sent for checking only while it is on, and is never sold or used for advertising.
The dictionary, flashcards, spaced repetition and your error profile are free for good. Daily AI allowances (30 checks today) may be tuned during the alpha as we learn real usage — but a useful free tier is part of the model.
English, Russian, German and Spanish are available today — learn English with explanations in your native language, or the other way around. French and Italian follow.
Most grammar checkers fix the current sentence and stop there. Courses give everyone the same pre-written material. YabLab saves the words and mistakes that are actually yours, turns them into a personal learning profile, and brings them back through targeted practice and spaced repetition. The goal isn’t just to correct today’s sentence — it’s to help you stop making the same mistake. Your error profile is also a ready-made track of your weak spots — a perfect starting point for working with a tutor.

Everywhere you learn: the Chrome extension (and other Chromium browsers) and the Mac app — it translates any text on screen and checks your writing in any app. On iPhone — flashcards and drills for practice on the go. The web app works in any browser; Firefox is next.
