Which one is for you
Pick Grammarly if
- Fits if you write in lots of places and want the same checks in each
- Works for people writing English as a second language, and students who want citation and plagiarism checks in one place
Look elsewhere if
- Skip it if a spell checker is all you need, as your browser has one
- Pricey if you pay month to month: $30, against $12 on yearly billing
- Not for you if you write in a language outside its main six, which only get spelling and basic grammar
- Tight if you lean on AI for free, with 100 prompts a month and no full-sentence rewrites or tone changes
- Watch out: Pro stops at 149 seats, Enterprise has no public price, and reviewers say it flags correct text and nags you to upgrade
Pick Sapling if
- Fits if you write support replies or sales emails all day and want saved snippets
- Works for developers who want a grammar or AI-detection API
Look elsewhere if
- Skip it if you need it on every site for free, as unlimited use on premium domains needs Pro
- Tight if you stay on Free: 20 snippets and AI checks capped at 2,000 characters
- Watch out: the API is billed separately, per character, with a $5 minimum
- Pricey if you're buying for a team, as Enterprise starts at 10 seats and chat assist is only there

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
