Prices may change. These are correct as of 8 Nov 2026. Please confirm on the vendor's own page before you pay.

Unverified: Sources disagree. The plans page and help centre say Pro is $12 per month billed yearly or $30 billed monthly. Grammarly's Superhuman-suite help article lists Pro at $12 yearly but $15 when billed monthly. The yearly price agrees; the monthly price does not.

Free plan

Free plan: 100 AI prompts per month. Free also covers basic grammar, spelling and tone detection.
