Compare Proofreading Software
Proofreading software checks writing for errors; the right choice depends on supported languages and where you write. Tools in this category can be compared by platform, browser extensions, document integrations, style and tone suggestions, team features, and offline mode.
Check the free-plan and paid-price details before choosing, and look for the API, open-source, and free-tier marks when those matter to your setup. A free plan and a free trial are different: check the listing for the option it offers.

How to choose
Which platforms does it need to run on?
Choose a tool that works where you write. Compare its supported platforms and check whether it offers a browser extension if you want proofreading in a browser.
Does it work with the documents and apps I use?
Check the document integrations listed for a tool against the apps you already use. A browser extension may suit browser-based writing, while an integration may connect proofreading to a document workflow.
Does it support my language and writing style?
Compare supported languages and look for style and tone suggestions if you want help beyond spotting errors. The available facts do not specify which languages or suggestions a particular tool includes.
Can I use it for free, and what does paid access cost?
Check whether a listing offers a free plan, a free trial, or both, and compare the paid starting price and billing terms. For example, DeepL Write lists a free plan and paid access from €6.99 per user per month on annual billing; Hemingway Editor lists a free plan, paid access from $8.33 per user per month on annual billing, and a 14-day trial.
Do I need team features or offline access?
If you work with a team or need to write without an internet connection, compare the team-features and offline-mode details. Confirm the specific support in the listing before choosing.
