Grammarly
Grammarly is a writing assistant that lives where you already type — browser, email, docs, and desktop apps — correcting grammar, sharpening clarity, and (on paid tiers) rewriting and drafting with AI. Its distribution is the moat: it's simply everywhere you write.
The verdict
The free tier is the best zero-cost writing upgrade available, full stop. Premium is worth it for people whose writing is their work; casual writers can stay free forever without guilt.
A look at Grammarly

Best for
Anyone whose credibility rides on written English — email-heavy roles, non-native speakers, content teams.
Not for
You write rarely, or your organization restricts cloud text processing for confidentiality.
THE TRADE-OFFS
Pros & cons
- Works across virtually every surface you type on.
- Free tier covers correctness basics indefinitely.
- Tone and clarity suggestions genuinely improve business writing, not just fix typos.
- Premium's value over free is incremental if you only need correctness.
- Cloud processing of everything you type is a real consideration for sensitive work.
