Which one is for you
Pick ProWritingAid if
- Fits if you write fiction and want feedback on a chapter, not only on your commas
- Works for editing in Scrivener, Word or Google Docs with the checks inside them
Look elsewhere if
- Pricey if you pay monthly, at $30 for Premium against $120 for the whole year
- Tight if you're staying free, since it checks at most 500 words at a time and runs each report twice a day
- Not for you if you edit offline, because the web editor and every integration, desktop apps included, need a connection
- Watch out: Manuscript Analysis and the other full-story tools need Story Credits, bought apart from the subscription
- Watch out: plagiarism checks are sold separately in bundles of up to 2,000 words a check, and there are no phone apps
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

|---|---|---|
| Value for money | CPremium is $10 a month billed yearly ($120), which sits in the middle band for writing tools, where plans run from about $5 to $12.

Fine for an email, not a chapter. | CThe free plan gives basic suggestions, 20 snippets and AI checks up to 2,000 characters, on free domains only. A 1-month Pro trial needs no card. |

The listing puts chat assist on Enterprise only. |

Everything needs a connection, the desktop apps included. | CNo store rating on record. You install an extension or add-in and connect it to each place you write. |
| Platforms and integrations | BA web editor, desktop apps for Windows and Mac, Chrome, Edge and Firefox extensions, and a real list of places it works inside: Word, Scrivener, Google Docs, Atticus, Vellum, Apple Notes, Notion and Wattpad. No phone apps, which keeps it off an A. | BBrowser extension and add-ins for Google Docs, Word, Outlook, Gmail and Slack, plus an API. No desktop or phone app listed. |

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.
