What it is
A writing assistant that checks grammar, spelling, clarity, and tone across the apps you already use, with plagiarism and AI-detection checks on the paid tier.
The solopreneur use case
For most freelance writers Grammarly Free is enough until you’re shipping client deliverables daily and want the plagiarism and AI-detection safety net — the point at which Pro pays for itself in one avoided embarrassment.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | Free | Grammar, spelling, basic clarity |
| Pro | $12/month | Annual billing; rewrites, tone, plagiarism + AI detector |
| Business | $15/month | Per user; team styles |
Pricing correct as of last review. Check Grammarly's site for current plans.

Our verdict
The volume pick. Grammarly Free is enough for most writers; upgrade to Pro ($12/mo annual) once daily client delivery makes plagiarism and AI-detection checks worth the safety net.
