About Prooftext

Grammar help without the clutter

Prooftext is a free grammar checker designed to fix mechanical writing issues first and keep the original message intact.

Minimal edits Single-purpose checker Structured text preserved

What it does

Prooftext reviews writing for grammar, punctuation, spelling, apostrophes, and sentence-level cleanup. It is designed as a focused grammar checker rather than a multi-mode rewriting tool. Try the free grammar checker to run a draft through it directly.

What it protects

The service is designed to preserve meaning, names, URLs, email addresses, dates, numeric values, money values, percentages, bullet lists, and important line breaks.

How it behaves when unavailable

If the grammar provider is unavailable, Prooftext reports a visible warning instead of pretending to generate edits. Go back to the checker page to test the current provider status.

Next step

After reviewing how Prooftext handles grammar and provider warnings, head back to the main checker and run your own text through it.
