AI writing assistant for grammar, tone, and rewriting — works everywhere you type via browser extension and desktop app.

DEV-TOP · horizontalOur take
Best for anyone who wants lightweight, always-on writing help embedded directly into their existing apps rather than a separate chat window — Pro's $12/mo is one of the more affordable entries in this category.

| Plan | Monthly | Annual | Key limits |

| Free | Free | Free | Spelling/grammar correction, tone detection, 100 AI prompts |
| Pro | 12 USD/mo | — | Full-sentence rewrites, tone adjustment, unlimited personalized suggestions, plagiarism and AI detection, 2,000 AI prompts; 7-day free trial available |
| Enterprise | — | — | Custom pricing; proactive AI everywhere, dedicated support, BYOK encryption, custom roles/permissions, data loss prevention, cost center visibility |
Free plan gives real, everyday grammar/spelling correction and 100 AI prompts/month across supported apps and browsers — enough for casual use, but heavier AI rewriting and plagiarism/AI detection require Pro. No separate self-serve Business/Team tier was shown between Pro and Enterprise on the current pricing page — VERIFY whether that tier still exists.
