ProWritingAid is a writing analysis platform built for long-form content. It runs 25+ specialized reports covering sentence length variation, passive voice density, pacing, readability, and structural issues — not just grammar and spelling. It integrates with Google Docs, Microsoft Word, Scrivener, and Chrome.
For content marketers producing in-depth articles or managing freelance writers, the depth of analysis goes well beyond what Grammarly's standard tier offers. The lifetime license is the standout value play if you plan to use it for 3+ years.
| Plan | Monthly | Annual | Lifetime |
|---|---|---|---|
| Free | $0 | $0 | — |
| Premium | $30/mo | $120/yr | $399 one-time |
| Premium Pro | $36/mo | $144/yr | $699 one-time |
The lifetime license reaches cost-parity with annual billing after about 3.3 years. If you're planning to use ProWritingAid long-term, the one-time purchase eliminates renewal costs entirely. The free plan caps analysis at 500 words per session — not practical for full articles.
