WritingProductivity
Writing assistance that edits, rewrites, and checks tone in context. Grammarly works where you write—browser extension, desktop apps, mobile keyboards, and the Grammarly Editor or docs. Real-time suggestions cover grammar and clarity; generative AI and agents help you draft, rewrite, and adjust tone on demand.
Write naturally in any supported app. Review red underlines for grammar/spelling and blue underlines for clarity/tone. Click a suggestion to accept or dismiss.
What to provide
Details that improve the result
Example prompt
Draft a client email in Gmail with Grammarly enabled. When a blue underline appears on a long sentence, open the suggestion and choose a clearer rewrite. Keep product names and dates exactly as written.
If the first output is not good
Common mistakes
Highlight text, click the pencil or lightbulb icon, pick a suggested prompt or type your own instruction. Insert the rewrite or continue editing with Rephrase.

If the first output is not good
Common mistakes
Open docs in the Grammarly Editor. Use AI Chat to brainstorm or outline, write in the main surface with real-time suggestions, then open agents on the right for paragraph-level rewrites.

If the first output is not good
Common mistakes
Open Paraphraser in docs or Superhuman Go, pick a preset or custom voice, review paragraph-level suggestions on the left panel, accept or dismiss each rewrite.

If the first output is not good
Common mistakes
Open Humanizer on the agents tab, choose a voice or create one, hover left-side bars for actionable feedback, apply edits line by line.
What to provide
Details that improve the result
Example prompt
Paste an AI-drafted partnership email. Open Humanizer, select your custom voice, review bar hints on stiff phrases, apply edits until the tone sounds sincere and specific.
If the first output is not good
Common mistakes
Open AI Chat in Grammarly for Mac, Windows, or docs. Describe the task, iterate on the response, then move the result into your document for Grammarly review.
What to provide
Details that improve the result
Example prompt
AI Chat: “Draft three subject lines for a webinar invite. Audience: HR leaders. Under 50 characters. No exclamation marks. Offer: async interview training.” Pick one, paste into the email body, refine with generative rewrite.
If the first output is not good
Common mistakes
Grammarly prompts work best when you highlight specific text and state the change you want—shorter, clearer, more formal, or in your voice. In AI Chat and docs, lead with audience, purpose, length, and what must not change.
Highlight the paragraph. Goal: clearer and more direct. Audience: existing customers. Constraints: keep the March 15 date and pricing; under 120 words.
Generative rewrites target selected text. Smaller, focused selections produce more controlled edits than selecting an entire document.
Example
Highlight one paragraph, click the lightbulb, choose “Make it clearer” or type “Shorten by 25% while keeping all product names.”
Audience, formality, and domain goals steer real-time suggestions and tone detection before you invoke generative AI.
Example
Set audience to Expert and domain to Technical Documentation, then draft. Blue suggestions will favor precision over simplicity.
Paraphraser and Humanizer share voice profiles. Add writing samples so rewrites match your tone instead of a generic preset.
Example
Create a voice named “Support tone” with three past support replies, then select it in Paraphraser for new ticket responses.
Paraphraser changes style presets; Humanizer softens AI stiffness; Grammarly agent categorizes full-document issues; AI Chat drafts from scratch.
Example
AI Chat for outline → draft in docs → Paraphraser Professional → Humanizer with custom voice → Grammarly agent final pass.
After a generative rewrite, use Rephrase or a new prompt on the same selection instead of rewriting the whole document.
Example
After “Make more formal,” follow with “Keep formality but shorten the second sentence.”
Write where Grammarly is installed
Grammarly works in browser extensions, Windows/Mac apps, mobile keyboards, and the Editor/docs. Suggestions appear in context—no copy-paste loop for supported apps.
Understand underline colors
Red underlines flag grammar, spelling, and critical word-choice issues. On paid plans, blue underlines suggest clarity, engagement, and delivery improvements.
Highlight for generative AI
Select text, click the pencil or lightbulb icon, and choose a prompt or type your own. Paragraph-level rewrites work best on focused selections.
Use Rewrite in my voice
Grammarly builds a voice profile from your writing. Highlight text, choose Rewrite in my voice, and insert or rephrase from there.
Pick the right agent in docs
AI Chat for brainstorming; Paraphraser for style presets; Humanizer for natural-sounding AI text; Grammarly agent for categorized full-document review.
Create shared custom voices
Name a voice, add writing examples, and use it in both Paraphraser and Humanizer. Delete voices you no longer need.
Set goals before you draft
Audience, formality, and domain settings steer suggestions. Adjust them when switching from, say, a blog post to a legal email.
Protect must-keep facts
Grammarly improves writing—it does not verify truth. State which dates, numbers, names, and claims must appear verbatim before rewriting.
Review Paraphraser suggestions individually
Paragraph rewrites appear on the left panel overlaid on your text. Accept, dismiss, or undo each edit—you stay in control.
Humanize AI drafts before sending
Humanizer targets robotic phrasing in AI-generated emails, proposals, and posts. Hover left-side bars for specific edit hints.
Use AI Chat for structure
Ask AI Chat for outlines, subject lines, or first drafts, then paste into docs and run inline Grammarly plus agents for polish.
Iterate with targeted follow-ups
After a rewrite, use Rephrase or a new prompt on the same highlight instead of restarting the whole document.
Check team admin settings
Enterprise, Business, and Education admins enable docs, agents, and paragraph rewrites on Feature access and Agent access pages.
Do not confuse clarity with accuracy
A clearer sentence can still be wrong factually. Verify numbers, policies, and quotes yourself after Grammarly edits.
Match preset to audience
Professional for business email, Academic for papers, Streamlined for docs, Creative for marketing, Simple for general readers, Humanize for conversational tone.
