Bottom line: Grammarly is still the most convenient writing assistant in 2026 because it works almost everywhere you type: email, documents, browsers, and chat apps. The free plan handles spelling and grammar well, and Pro adds rewrites, tone adjustments, and generative AI. It is now part of the Superhuman suite, but you can still buy Grammarly Pro on its own. If you already pay for a general AI assistant, weigh whether you need both.

Strengths
- Works everywhere. Suggestions appear in email, documents, forms, and chat without copying text into another app.
- Strong free plan. Covers the basics for most people.
- Team consistency. Style guides and brand tones help a team sound like one company.
- Low friction. Almost no learning curve.
Weaknesses and Watch-Outs
- Overlap with AI assistants. If you already pay for ChatGPT or Claude, much of Pro’s generative AI duplicates what you have.
- Monthly pricing. Paying month to month costs more than twice the annual rate.
- Suggestions are not always right. Accept rewrites selectively so your voice does not flatten.
- Sensitive text. Grammarly reads what you type in supported apps; set rules for confidential documents with our AI governance policy template.
Who Should Choose Grammarly
- Anyone who writes a lot of email and client communication and wants polish without switching apps.
- Teams that want consistent tone and terminology across staff.
- Non-native English writers who want real-time guidance.
