Grammarly
Grammarly is an AI writing assistant that checks grammar and clarity, suggests tone and rewrites, and generates text across apps and browsers.
About this tool
Grammarly started as a grammar checker and has become a broader AI writing assistant. It reviews what you type in the browser, desktop apps and many websites, flags spelling, grammar and clarity issues, suggests changes of tone and can rewrite whole sentences or paragraphs. It can also generate text from prompts, with the number of prompts depending on your plan.
Recent additions include agents that estimate whether text looks AI-generated and that rework writing to sound more personal. Grammarly is now part of the Superhuman company. For organisations, the Enterprise plan adds style guides, brand terms, administration and security controls, and Grammarly publishes a SOC 2 Type 2 report.
What you can do
Proofreading and clarity
Grammarly checks grammar, spelling, structure and clarity as you write and explains each suggestion so you can accept or ignore it.
Tone and rewrites
Paid plans suggest how to adjust tone for the context and offer full-sentence or paragraph rewrites for smoother writing.
Generative prompts
You can ask Grammarly to draft or transform text; the Free plan includes a small monthly number of prompts and paid plans many more.
AI detection and humanizer agents
One agent highlights passages that may read as AI-generated, and another helps revise text so it sounds more like you.
Who is it for?
- A non-native English speaker polishes emails and reports before sending them.
- A team keeps product names and style consistent with a shared style guide.
- A student checks clarity and tone in an essay draft before submission.
Before you choose
AI detection estimates are not proof of how a text was written; avoid using them alone to judge someone’s work.
Because Grammarly reads what you type in many apps, review its privacy settings and your organisation’s policies before using it on confidential material.
