โ€” Writing Tool

ProWritingAid

Last updated June 20, 2026 ยท Reviewed by ToolForge Editorial

The editor that fixes grammar, style, and structure โ€” not just spelling.

โ˜… 4.5/5 ยท 3M+ writers ยท Since 2012 ยท Free tier (500 words/check)

The editor that thinks like a book coach

ProWritingAid isn't a Grammarly clone โ€” it's a 25-report style editor that catches things the spelling checkers miss. Passive voice overuse, sticky sentences, cliche density, pacing problems, dialogue ratio, readability grade level, sentence variety. The reports feel like having a developmental editor reading over your shoulder.

Who it's for: Novelists, journalists, content marketers, and non-fiction authors who care about craft. Less useful for casual email.

Key features

25+ Reports Style diagnostics

Real-time reports on sticky sentences, pacing, dialogue, readability, repeated words, vague adjectives. Goes way beyond grammar to structural editing.

Rephrase AI sentence rewriter

Click any sentence, get 5 rewrites in different styles (concise, formal, fluent). Saves you from staring at the same paragraph for 20 minutes.

Word Explorer Thesaurus on steroids

Double-click any word โ€” get definitions, synonyms, rhymes, alliterations, pronunciation. Built-in dictionary that thinks like a writer.

Integrations Scrivener, Word, Google Docs

Plug into Scrivener, MS Word, Google Docs, Chrome, Edge, Firefox, iOS, Android. Works where you already write.

The honest take

โœ“ What works

  • 25+ writing reports โ€” most thorough in the category
  • Rephrase AI is genuinely useful for stuck sentences
  • One-time $399 lifetime option (rare in 2026 SaaS)
  • Privacy-respecting โ€” your text isn't used for training
  • Better than Grammarly for fiction and long-form

โœ— What doesn't

  • Free tier is limited to 500 words per check
  • UI can feel overwhelming โ€” 25 reports is a lot
  • No tone-of-voice detection like Grammarly has
  • Slower than Grammarly on real-time checks

Verdict

If you're writing anything longer than an email โ€” a blog post, a novel, a whitepaper โ€” ProWritingAid will make you a better writer. The 25 reports feel like having a writing teacher. At $30/mo Premium (or $399 lifetime), it's a solid investment for serious writers. Casual email users should stick with Grammarly's free tier.
