Integrations: Grammarly Wins Clearly

Grammarly works everywhere: every browser, every platform, iOS and Android keyboards, Gmail, Notion, Slack, Google Docs, Word. It's invisible and automatic.

ProWritingAid's integration is more limited — Chrome extension only for browsers, no mobile keyboard. For freelancers writing across multiple platforms daily, this is a significant disadvantage.

Depth of Analysis: ProWritingAid Wins

ProWritingAid offers more detailed writing reports — overused words, sentence length variation, readability scores, style consistency, pacing. For novelists and serious long-form writers, this depth is genuinely useful.

Grammarly's suggestions are more surface-level but more actionable for everyday writing.

Price: ProWritingAid Wins Long-Term

ProWritingAid's lifetime deal at ~$399 is exceptional value. Compared to Grammarly at ~$144/yr, you break even in under 3 years — and then it's free forever.

For freelancers confident they'll use a writing tool long-term, the lifetime deal is worth considering seriously.

Who Should Use Each Tool?

Grammarly is better for:

• Freelancers writing across many platforms daily
• Email, Slack, social media, and browser-based writing
• People who want AI-assisted rewrites (GrammarlyGO)
• Non-native English speakers who need constant assistance

ProWritingAid is better for:

• Long-form writers (bloggers, authors, copywriters)
• Writers who want deep style improvement, not just error-catching
• Budget-conscious users who can use the lifetime deal

Final Verdict: Grammarly for Most Freelancers

For the typical freelancer writing emails, proposals, and content across multiple platforms — Grammarly's superior integrations win. It's the tool that actually gets used because it's always there.

ProWritingAid is the better choice if you write mostly in one editor and want serious style improvement for long-form work.
