You have been clicking Accept for years and you still make the same mistakes.
Grammar Coach explains every correction in plain language and makes you read the explanation before it will let you apply the fix. Same red underlines you are used to — except this time something sticks.
Free tier, no card required. Pro is $6/month.
Hi team, I have push the fix to staging and their is still a issue with the login flow.
Grammar
“their” is a possessive pronoun. You want “there”, which introduces the existence of something.
→ there
Accept is disabled until the explanation has been on screen. You can turn the delay off — but it is on by default for a reason.
How it works
You write, anywhere
Gmail, Slack, Notion, a GitHub issue, a text box on some random admin panel. If you can type in it, it gets checked.
It flags what is wrong — and why
Hover a highlight and you get the actual reason: which rule, what it should be, and what makes it wrong. Not just a replacement word.
Accept unlocks after you read
The Accept button stays disabled for a beat. Long enough that you have to look at the explanation before the fix lands. That pause is the whole product.
Your patterns surface over time
Every correction is filed by category. After a week you can see that you keep doing the same three things — which is the part that actually changes your writing.
Pricing
The free tier is a real tier, not a teaser. If 25 checks a day covers you, stay on it.

Questions
How is this different from Grammarly?+
Grammarly optimises for making the correction disappear as fast as possible. One click and it is gone. That is great for output and useless for learning — you can use it for years and make the exact same mistakes. Grammar Coach deliberately adds friction: you read why before you accept, and it tracks which mistakes you repeat.
Does it work offline?+
No. Corrections come from a language model running on our server, so it needs a connection.
Is my writing stored?+
By default, no. We store the category of each mistake (for example "subject-verb agreement") and whether you accepted it — not the text itself. Keeping the actual flagged text is an explicit opt-in you control, and turning it back off erases what was kept. See the privacy policy for details.
What happens when I hit the daily limit?+
Checking pauses until the next day. Nothing is lost and nothing is charged — the cap exists so a runaway loop cannot generate a surprise bill.
Which browsers are supported?+
Chrome today. Other Chromium browsers are likely to work but are not tested. Firefox and Safari are not supported yet.
Can I cancel?+
Any time, from your account page. You keep Pro until the end of the period you already paid for, then drop to Free.
