Outwrite
Rewrites sentences for clarity and length and shows a readability score as you edit, on top of standard grammar and spelling checks.
What you'd use it for
Tightening wordy sentences and watching a readability score improve as you edit, not just catching grammar mistakes.
- Rewrites a sentence to make it shorter, longer, or differently phrased, with alternatives to pick from
- Shows a live readability and grade-level score that updates as you edit
- Flags passive voice and points to an active-voice rewrite
- Checks spelling, grammar, and punctuation in English, French, and Spanish text
- Runs up to 50 plagiarism checks a month on the Pro tier
The verdict
Outwrite is a competent grammar and spelling checker with one real differentiator, sentence rewriting paired with a live readability score, so tightening prose becomes something you watch happen rather than a checklist. That differentiator sits entirely behind the $9.95/mo Pro tier; the free plan is grammar and spelling only, no better or worse than half a dozen other checkers. It suits someone who already knows their writing runs long or dense and wants to see the number move as they edit, not someone hunting for a free grammar checker, since plenty of those exist without a paywall on the interesting part.

Where it breaks
The Teams price ($7.95/user/mo) is lower per seat than the individual Pro price ($9.95/mo), which is a normal team discount, but Outwrite doesn't state a minimum seat count for it — confirm before assuming it applies to a two-person team.
Browser extension, Google Docs and Word integrations. Formerly known as GradeProof, with a long-running free user base. Monthly and yearly billing are both available, switchable in account settings.

When not to use it
Not for anyone who just wants free spelling and grammar corrections, since the free tier is unremarkable and the rewriting features that justify Outwrite's existence sit behind Pro. Also not for teams running heavy plagiarism screening, since Pro caps checks at 50 a month.
Outwrite’s real feature is sentence rewriting with a live readability score — beyond catching grammar errors, it suggests shorter or clearer phrasings and shows you a number that moves as you edit, which turns “improve your writing” from a vague instruction into something you can watch happen. That’s a genuinely different emphasis from a pure grammar checker like Linguix, which corrects but doesn’t restructure.
What the free tier leaves out
Free covers spelling, grammar, and a thesaurus — a solid basic checker — but the rewriting and structural suggestions, the actual differentiator, sit behind Pro at $9.95/mo. If sentence-level rewriting is the reason you’re looking at Outwrite specifically, budget for the paid tier; the free version won’t show you what makes this tool distinct.
The plagiarism check is capped
Pro includes 50 plagiarism checks a month, not unlimited — worth knowing if you’re a student or content writer running checks on every piece, since that cap could bind faster than the writing-assistance features do.
Where it fits next to Linguix
Outwrite and Linguix are close competitors at similar price points; Linguix’s edge is typing-shortcut automation for repeated text, Outwrite’s is sentence-level rewriting and readability scoring. Pick based on which problem you actually have — repetitive typing, or wordy writing that needs tightening.
