ProWritingAid has a free tier and two paid plans as of July 2, 2026: Premium at $30/mo and Premium Pro at $36/mo, both dropping about 67% annually to $10/mo and $12/mo. Free caps you at 500 words a check; paid plans lift the limit and open the full report set. A one-time Lifetime option exists too. The cost easy to miss is Story Credits, the manuscript and beta-reader analyses bought separately and in no plan, though paid tiers get up to 40% or 65% off. Deep author features are sold a la carte.
At $30/mo to start, ProWritingAid sits 3% above the $29/mo median across 9 ai writing tools tools we track.
The annual price is the headline saving. The line most authors forget is Story Credits, which sit outside every subscription.
Independent analysis · ProWritingAid
ProWritingAid is cheap where it counts: Premium at $30/mo, or about $10/mo on the annual plan, with Premium Pro a few dollars more. For long-form writers who want unlimited word counts and the full set of style reports, the annual rate is strong value against generalist AI tools. A one-time Lifetime license exists too, which suits writers who would rather avoid a recurring bill entirely.
Users report the tool slowing badly on large documents, which undercuts the "unlimited" word-count promise for exactly the novelists it targets. The browser extension is also described as buggy, and there is no mobile app, so the paid experience is uneven outside the desktop tool.
Based on analysis of recent Reddit and G2 discussions.
Casual writers can live on the free tier, but novelists and serious long-form editors get real value from Premium at roughly $10/mo annually, or the Lifetime license if they hate subscriptions. Budget separately for Story Credits if you want the manuscript analyses. If you need a stable browser extension and a mobile app more than deep reports, Grammarly is the steadier pick.
