How to Use Grammarly AI Chat for Drafting and Ideation

Grammarly AI Chat helps you brainstorm, outline, and draft inside Grammarly Docs. It is the agent to open when you need ideas or a first pass, not when you only need a tone tweak. After Chat produces structure, you can move to Paraphraser, Humanizer, or inline review. For the product overview, start at /explore/grammarly.

This guide shows a drafting workflow: brief, ideation prompts, section drafts, fact checks, and handoff to other agents. Pair it with Docs setup at /blog/how-to-use-grammarly-docs-and-ai-agents-for-writing and with Humanizer polish at /blog/how-to-use-grammarly-humanizer-for-natural-sounding-ai-drafts. Generative AI prompt limits differ by plan, with Free, Pro, and Enterprise signals listed on grammarly.com/plans.

When to use AI Chat

Use AI Chat when the page is blank, when you need title options, when you need an outline, or when you need a rough section to edit. Skip AI Chat when the draft already exists and only needs style. In that case use Paraphraser or generative rewrite tools instead. Chat is also a good place to pressure test objections and agenda options before you spend time on polished prose.

AI Chat can invent confident details if your brief is thin. Your job is to supply facts, exclusions, and output shape. Grammarly checks writing quality later. It does not certify that Chat invented numbers are true.

How Chat fits with other Docs agents

Think of Chat as the starting engine. Paraphraser changes style while preserving meaning. Humanizer makes AI assisted prose sound more natural. The Grammarly agent supports broader review. Other Docs agents such as Reader Reactions, Citation Finder, AI Detector, Plagiarism Checker, and AI Grader may appear depending on plan and admin Feature access. Explore those inside the product when relevant rather than forcing them into every draft.

Step by step AI Chat workflow

1. Write a drafting brief first

Include audience, length, must keep facts, forbidden claims, and deliverable shape. Paste the brief into Chat as the first message.

Drafting brief
Audience: operations managers
Deliverable: 700 word process blog
Must keep facts: weekly risk review, single onboarding owner, kickoff template
Forbidden: invented ROI percents, fake customer quotes
Tone: practical
Output first: title options and H2 outline only

2. Ideate before you draft full prose

Ask for outlines, angle options, or objection lists first. Full prose too early locks you into a weak structure and spends more prompts to repair.

Ideation prompt
Using the drafting brief, propose:
1) 5 title options under 8 words
2) 3 H2 outlines
3) For each outline, one risk if the article stays too generic
Do not draft full paragraphs yet.

3. Draft one section at a time

Choose an outline, then ask Chat for section 1 only. Edit facts. Then request section 2. Section sized drafts are easier to verify than a full essay dump.

Section draft prompt
Draft H2 1 only in about 160 words.
Use only facts from the brief.
If a needed detail is missing, insert [[NEED FACT]] instead of inventing.
End with one practical checklist of 3 bullets.

4. Lock facts and remove placeholders

Search for any [[NEED FACT]] markers. Replace them with real sources or delete the claim. Never publish placeholders or invented fills.

Fact cleanup checklist
[ ] No [[NEED FACT]] left
[ ] No statistics without a source note
[ ] Names and dates match the brief
[ ] Plan claims point to grammarly.com/plans when relevant
[ ] Quotes attributed or removed

5. Hand off to rewrite agents, then inline review

Send stiff paragraphs to Humanizer. Send wrong tone paragraphs to Paraphraser. Finish with red and blue underline review. That sequence keeps ideation, style, and correctness in separate passes.

Handoff sequence
AI Chat -> structure and draft
Humanizer -> natural sounding stiff sections
Paraphraser -> tone mismatches
Inline review -> critical and clarity marks
Final read -> protected facts still true

Copyable AI Chat prompts and samples

Use these prompts in Docs AI Chat. Swap bracketed parts. Keep the no invention lines.

Brainstorm angles

AI Chat prompt
Topic: reducing onboarding confusion for new engineers
Audience: engineering managers
Give 6 article angles.
For each: one sentence promise, one audience pain, one section to exclude.
Do not invent survey data.

Outline with exclusions

AI Chat prompt
Create an outline for a 800 word guide on writing better incident updates.

AI Chat prompt
Turn these bullets into a professional email under 120 words:
- Beta opens 3 September
- Invite list capped at 50 companies
- Need security review approval by Friday

Then pick the clearest one and tighten to 35 words.
Must include: hotfix live, watch payments for 1 hour, owner Sam.

Blog section with fact gaps labeled

AI Chat prompt

Then mark your top 3 with one reason each.

Rewrite brief for Chat when draft is messy

AI Chat prompt
Here is a messy draft. Do not expand it. Reorganize into:
1) decision needed
2) context
3) risks
4) ask
Keep all existing facts. Delete repetition. Flag unknown items as [[NEED FACT]].

DRAFT:
We maybe need a template and also owners are unclear and Friday might work for publishing if Priya is okay and security might be a blocker.

Customer story without fake quotes

AI Chat prompt
Draft a 120 word customer story framework for Acme onboarding.
Use only these facts: 80 seats, 62 active in 14 days, SSO still pending for 2 admins.
Do not invent quotes. Use placeholders like [QUOTE PENDING] if a quote is needed.

Help center outline

AI Chat prompt
Outline a help center article: reset password.
Sections: before you start, steps, troubleshooting, when to contact support.
Style: imperative bullets.
Do not invent product menu names. Use [CONFIRM IN UI] where a label is unknown.

Length target 700 words later.
Must include kickoff template and single owner model.
Forbidden: ROI stats, vendor rankings.
First response: outline only.

Tips and verification

Chat quality tracks brief quality. Short vague asks produce generic essays. Strong briefs produce usable outlines. Keep Free and Pro prompt allotments in view during long ideation sessions. On managed Enterprise, Business, or Education accounts, confirm Docs and AI assistant access on the Feature access page if Chat is missing. Save strong briefs as reusable templates so teammates start from the same constraints and spend fewer prompts on vague regenerations. Review every draft for protected facts before you hand it to Humanizer or Paraphraser.

• Ideate outlines before full prose
• Draft section by section with [[NEED FACT]] markers
• Never publish invented metrics
• Hand off to Humanizer and Paraphraser for polish
• Verify plan limits at grammarly.com/plans

Common mistakes

• Asking Chat to write everything in one vague prompt
• Accepting invented statistics because the prose sounds polished
• Using Chat for a tone tweak that Paraphraser should handle
• Skipping fact cleanup for [[NEED FACT]] markers
• Regenerating entire documents instead of editing one section
• Ignoring Free generative AI prompt limits on plans pages
• Publishing Chat drafts without inline review
