Grammarly is a proofreader: it makes today’s email clean. YabLab is a coach: it fixes the same mistakes — then explains them in your native language, tracks them, and drills them until next month’s email doesn’t need fixing.
Grammarly
Its job is a polished document right now: grammar, tone, clarity, team style. It corrects you every day — and expects to correct the same mistake again tomorrow. For professional writing that’s exactly what you want.
YabLab
Its job is that you make fewer mistakes next month. Every correction becomes a rule card in your error profile: explained in your language, scheduled for review, drilled in short sessions until the rule is defeated.
Side by side, without the marketing fog.
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.
YouTube in two languages.
No chatbot tab, no lost context.
Any paragraph, at your level.
On any site — even on your Mac.
Practice what you get wrong.
Fewer mistakes every week.
For a language learner — yes: it checks your writing across the browser and explains every fix. If you need professional-grade tone rewriting for work documents, Grammarly still does that better. Some people run both: Grammarly for polish, YabLab for progress.
YabLab checks what you type in Chrome — email, chats, forms, social media. Passwords and sensitive fields are never read.
Each one lands in your error profile as a rule. YabLab schedules reviews with spaced repetition and builds short drill sessions from the rules most at risk.
Yes — the free plan includes writing checks and practice. Pro removes the limits when you want more.
