What is Grammarly?
Grammarly is the AI writing assistant that works everywhere you type — browser, email, Docs and Word. Beyond catching grammar and spelling, it rewrites for tone, clarity and concision, and its generative features can draft or reply from a short prompt. For professionals, students and anyone who writes email all day, it is the most frictionless way to sound more polished without changing tools. The free tier handles the essentials; Premium adds full rewrites, tone control and more.
When to stay on Free vs stack QuillBot or Claude for line edits without sanding off your voice: best AI for proofreading.
Best for: Polishing everyday writing — email, docs and messages — as you type.

What Grammarly is good at
- Catching mistakes in email and documents before you send them
- Softening or sharpening tone when the stakes are high
- Keeping a team writing consistently with a shared style guide
- Second-language writers wanting confidence, not just correctness
Use it without losing your voice
- Accept the mechanical fixes — spelling, agreement, punctuation — without thinking.
- Read every clarity and tone suggestion before accepting. This is where voice gets sanded off.
- Reject anything that makes a sentence more generic, even when it is technically "clearer".
- For important pieces, run it last rather than while drafting. It interrupts thinking.
Who should skip Grammarly
- Strong writers who find the suggestions homogenising — it nudges everything toward the same neutral register.
- Creative and literary writing, where its instincts actively work against you.
- Anyone unwilling to grant a browser extension access to what they type.
