Sample prompt to Joy's Assistant
Check this draft against our brand guidelines in the Knowledge Center. Tell me what matches, what drifts, and suggest rewrites for anything off-voice. Here's the draft: [draft].
What it can look like
An illustrative example. Your output will reflect your own sources, data, and prompts.
Check this draft against our brand guidelines in the Knowledge Center. Tell me what matches, what drifts, and suggest rewrites for anything off-voice. Here's the draft: Big news!!! We just shipped the most revolutionary update in Fieldline history. Our game-changing AI engine will completely transform how you work. You'd be crazy to miss it. Sign up for early access before it's too late. The update also includes smarter search filters, faster load times, and a redesigned mobile app.
I checked the draft against the Brand Voice Guidelines v3 in the Knowledge Center. The short version: the second half sounds like Fieldline, the first half doesn't, and all four problems sit in the opening three sentences.
Verdict: close, but not on voice yet. The structure is right and the feature copy passes cleanly; the opening drifts into hype and pressure tactics the guidelines explicitly rule out.
Scored dimension by dimension, the split is stark: the draft lands on voice for showing rather than shouting (90) and its second-person address (88), but falls short on understatement (30), punctuation restraint (35), the banned-word sweep (40), and respect for the reader (45). Every low score traces back to the opening three sentences.

What matches. The closing line (smarter search filters, faster load times, and a redesigned mobile app) is concrete and benefit-first, exactly what the "show, don't shout" section asks for. Sentence rhythm and the direct second-person address are also within voice.
What drifts.
Big news!!!: the guidelines cap punctuation at one exclamation point per piece, and none in openers.
the most revolutionary update in Fieldline history: superlatives and self-congratulation are on the never list; the voice is confident but understated.
game-changing AI engine will completely transform how you work: game-changing is a banned word, and the AI section says to state what the feature does, not that it exists.
you'd be crazy to miss it and before it's too late: pressure-based urgency and casual ableist phrasing both conflict with the "respect the reader" section.
Suggested rewrites.
Opening: Fieldline just got a major update. Here's what changes for your team.
AI line: The new AI engine drafts your job summaries for you, saving crews about 20 minutes a day.
Close: Early access opens this week. Join the list and we'll walk you through it.
One thing to confirm with the campaign team: these citations come from the May 2026 revision of the guidelines. If anyone is still writing from the v2 deck, the superlative rule is the main change to flag.
Want me to apply the rewrites and return the full clean draft, or run the same check on the landing page copy?
From draft to verdict in one paste
Brand Voice Check reads your brand guidelines in the Knowledge Center and holds any draft up against them. You get a clear verdict, the passages that match, the exact lines that drift (quoted, with the specific rule each one breaks), and suggested rewrites that keep the writer's point intact.
Put the guidelines on file
Add your brand voice guidelines to the Knowledge Center: the voice principles, the banned words, the tone rules. Whatever governs how you sound.
Paste the draft
Drop in an email, a landing page section, a social post, anything at all. Say who wrote it or where it will run if that context matters.
Review the verdict
Get what matches, the exact off-voice lines quoted with the rule each breaks, and a suggested rewrite for every flagged passage.
Fix it where it lives
Accept the rewrites you agree with and copy the corrected lines back into your doc, or ask Joy to apply them all and return a clean version to copy in one go.
Make it one click for your team
Save this ask as a custom command on the assistant your team already uses, customize it with your own sources and wording, and anyone can run it in one click.
Make it yours
Line-Level Citations
Every flag quotes the exact phrase and names the guideline it breaks. No vague 'tone feels off' feedback.
Rewrites, Not Just Flags
Each drifting line comes with a suggested fix that keeps the writer's point and moves only the voice.
Banned-Word Sweep
Your no-go list (superlatives, jargon, competitor phrasing) gets checked on every pass, automatically part of the verdict.
Self-Service for Writers
Anyone with access can run the check before submitting, so review time goes to judgment calls, not comma-level fixes.
Audience Register
Check against a specific register (developer docs versus executive email), where your guidelines define more than one.
Sub-Brand Rules
Point the check at a product line's own voice addendum when it differs from the master brand.
Localized Copy
Review translated drafts against the local market's tone rules, not just the English original.
Batch Review
Paste a whole campaign's assets in one conversation and get a consolidated verdict per asset.
Frequently Asked Questions
How do I check if content matches our brand voice?
Put your brand guidelines in the Knowledge Center, then paste any draft and ask for a check. JoySuite returns a verdict with the passages that match, the exact lines that drift (each quoted with the rule it breaks), and suggested rewrites.
What kind of drafts can Joy check?
Anything text-based: emails, landing pages, social posts, ad copy, press materials, even sales one-pagers. Paste the draft into the chat or point Joy at a document already in the Knowledge Center.
Does the check just flag problems, or fix them?
Both. Every flagged line comes with a suggested rewrite that keeps the original point and changes only the voice. Ask Joy to apply all the rewrites and it returns a clean version of the full draft to copy back into your doc.
Can freelancers and agencies use the same check?
Yes, and that's where it pays off most. Anyone you give access can run the check before submitting, so external copy arrives pre-aligned and your brand team reviews for judgment, not for banned words.
What happens when our guidelines change?
Update the document in the Knowledge Center and every check from then on uses the new rules. Joy reads the guidelines at ask time. Verdicts cite the section and version, so writers always know which revision they're being held to.
