Outwrite

Outwrite works across multiple platforms, so the grammar and style checks follow you into the places you already write instead of living in a single editor.

Outwrite is an AI writing assistant and grammar checker that corrects spelling and grammar, paraphrases sentences, and proofreads text for clarity.

The free plan covers basic grammar checking, which is enough for tidying emails and short documents.

Go further and you hit the paywall.

Advanced style and structure suggestions come with the premium plans, and plagiarism checks are limited on the free tier, so anyone who needs to check originality regularly will probably end up paying.

Team features sit only in the Teams plan, which matters if several people need to work from the same setup.

Outwrite is a reasonable starting point if you want a no-cost proofreader and may later want deeper editing help.

As with most tools in this category, the free version handles the basics and the more useful editing feedback costs extra.

Try the free plan first and see whether the basics are enough for you.
