Grammarly AI
Grammarly uses AI to check grammar, clarity, tone, engagement, and delivery in real time across emails, documents, and social posts. Its browser extension works everywhere you type online, making it the most ubiquitous AI writing assistant.
How to Get the Most Out of Grammarly AI
Set Goals to Tailor Suggestions to Your Audience and Tone
Before writing, click the "Goals" button and set your audience (expert, general, non-expert), tone (formal, informal, neutral), and intent (inform, describe, persuade). Grammarly adjusts every suggestion to match — it won't flag casual language as errors in a social post the way it would in a business report. This one step makes suggestions dramatically more relevant and reduces false positives.
Use Tone Detector to Calibrate Professional Emails
In the Grammarly Editor or sidebar, the tone detector shows how your email will read — "confident," "direct," "apologetic," or "concerned." For important client or stakeholder emails, check the tone label before sending. If it reads as more apologetic or hesitant than you intended, Grammarly suggests rewrites to project more confidence without changing the meaning.
Activate the Browser Extension for Consistent Writing Everywhere
Install the Grammarly browser extension and it works across Gmail, Slack, LinkedIn, Twitter, Notion, and virtually every web text input. Turn on real-time suggestions so you catch errors as you type, not after you've sent. For professionals who write in many different tools throughout the day, this ubiquitous coverage is Grammarly's biggest advantage over AI writing tools that only work in their own interface.
Our Take
Grammarly's browser extension that works everywhere is its strongest feature — no other AI writing tool comes close for day-to-day, in-context writing assistance across the web. It's the best choice for professionals who want consistent grammar and tone checking without switching tools. For generating content from scratch or long-form writing assistance, Claude or ChatGPT are more capable. Grammarly's premium plan is worth it mainly for the tone suggestions and advanced clarity rewrites; the free tier handles basic grammar correction well enough for casual use.
