Before you choose
Start with the price model
Check the Free plan field before entering payment details. A free plan and a free trial are separate listings, so review both fields.
If you need paid features, compare the published Paid from amount and its billing note. Linguix lists $11.67 per month with annual billing; iGrammar lists $10 per month and a 3-day trial; GrammarCheck.ai lists $2.50 per month with annual billing.
Match your devices
Choose the platform where you write most. The list covers web tools, browser extensions, Windows and macOS desktop apps, plus Android and iOS mobile apps.
Check the platform fields for the tool you are considering. A web option may suit shared computers, while a desktop or mobile app can fit a device-based workflow.
Compare the editing features
Use Style suggestions to see how a tool handles revisions. Tone detection can matter when your message needs a specific voice.
Review Languages supported if you write in more than one language. Compare these fields together rather than relying on a pricing label.
Check licensing needs
Harper is listed as free, while LanguageTool, Grammarly, Cordial, Linguix, MerciApp, iGrammar, Ginger, Scribens, GrammarCheck.ai, Typlx and Corrector.app use the pricing models shown in their entries.
If you need open-source software, use the Open source field and verify the licence details before adopting a tool.
Questions
Can I start with a free grammar checker?
Use the Free plan field to find tools that let you begin without a paid subscription. The list marks that option for qualifying entries.
Is a free trial the same as a free plan?
No. Free plan and free trial are separate fields. Check the pricing note for trial length and billing terms.
Which platforms do grammar checkers support?
The list covers web, browser extensions, Windows, macOS, Android and iOS. Check an entry's platform fields for its available apps.
What features should I compare besides grammar fixes?
Compare style suggestions, tone detection and languages supported, along with browser, desktop and mobile availability.
Do any listed tools use an open-source licence?
Use the Open source field to identify entries marked open source, then read the maker's licence terms before use.
