ProWritingAid is what you graduate to when Grammarly stops being enough. Where Grammarly focuses on catching errors in short, everyday writing, ProWritingAid — built by UK-based Orpheus Technology — is a full manuscript-editing suite. Its 20+ reports analyze style, sentence-length variety, pacing, overused words, clichés, sticky sentences, dialogue tags, and consistency of spelling and hyphenation across an entire document.

That last part matters for fiction writers: ProWritingAid will notice you spelled a character’s name two ways in chapter 3 and chapter 17. It’s also the only mainstream editor with a native Scrivener integration, which is why it dominates among novelists — Scrivener is where most books get drafted, and Grammarly can’t open its files. Integrations also cover Microsoft Word, Google Docs, browser extensions, and a desktop app for Windows and Mac.

Recent versions added AI features under the “Sparks” name: rephrasing sentences, adding sensory detail, and continuing text — plus critique reports that read a chapter and give feedback like a beta reader would. A plagiarism checker is available on higher tiers, aimed at students and content agencies.

Key Features

  • 20+ specialized reports: style, readability, pacing, echoes, clichés, and more
  • Document-wide consistency checking (spelling variants, hyphenation, capitalization)
  • Native Scrivener integration alongside Word, Google Docs, and browser extensions
  • Sparks AI tools for rephrasing and expanding text
  • Chapter critique reports with novel-specific feedback
  • Genre comparison — measures your prose against published books in your genre
  • Plagiarism checks on Premium Pro plans

Pricing

  • Free: core suggestions with a 500-word analysis limit
  • Premium: roughly $10/month billed annually (around $30 month-to-month) for unlimited word counts and all reports
  • Premium Pro: adds plagiarism checks and higher AI usage limits
  • Lifetime: a one-time purchase around $399 — frequently discounted — that many authors treat as the real deal

Best For

Novelists and long-form writers doing structural self-editing, especially Scrivener users; content teams enforcing style consistency; and budget-minded writers drawn to the lifetime license, which no direct competitor offers.

Limitations

The depth cuts both ways — first-time users face a wall of reports and settings, and working through them on a full manuscript takes real time. For quick real-time corrections in email and Slack, Grammarly remains snappier and less intrusive. The 500-word free limit also makes the free tier more of a demo than a usable tool.
