About Grammar Checker

Catch grammar, spelling, and clarity issues using our self-hosted LLM. It sits in the text shelf alongside 25 other text tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

It works from what you type in rather than a file and gives back JSON. It uses a model we host ourselves, not a third-party API. The work happens on our servers. There is nothing to upload, and any file it makes is deleted an hour later — 24 hours if you are signed in. The same operation is available programmatically at POST /v1/text/grammar-checker.

Grammar Checker questions

Where does Grammar Checker do its work?

On our own servers. There is no file to upload: what you enter is sent over TLS and processed on our infrastructure — no third-party processing APIs are in the path — and any file it makes is deleted within an hour.

Do I need an account to use Grammar Checker?

No. Grammar Checker works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.

Can I run Grammar Checker from my own code?

Yes. Every tool on the site is reachable from the REST API with the same slug — `grammar-checker` — and the same options as this page, so anything you can do here you can automate.
