copywriting

what it does

When the user wants to write, rewrite, or improve marketing copy for any page, including homepage, landing pages, pricing pages, feature pages, about pages, or product pages. Also use when the user says "write copy for," "improve this copy," "rewrite this page," "marketing copy," "headline help," "CTA copy," "value proposition," "tagline," "hero section copy," "this copy is weak," "this sounds like AI," "AI slop," "make it sound human," or "help me describe my product." Drafts never use AI tells like "it's not X, it's Y" reveals, "no X, no Y, no Z" lists, or sentences that trail into extra comma clauses. For email copy, see emails. For popup copy, see popups. For editing existing copy, see copy-editing. For the offer underneath the copy (bonuses, guarantees, value framing), see offers. Claims must be supportable, and a declined claim names the evidence that would unlock it. Diagnoses the input first (blank brief, real voice, or point edit) and changes only what it calls for.

“Write a short feature section for Pinpoint's new scheduled reports feature.”

Source material given with the request

with the skill
**Diagnosis:** A. One-line brief, no draft or voice to preserve. I'm building from the facts you gave and adding none. ## Feature section **Headline** Send any saved chart to up to 20 people, on schedule **Subhead** Pick a chart, choose a day and time, and Pinpoint emails it as a PNG and a CSV. Recipients can be anyone with an email address, including people who have never had a Pinpoint login. **Body** 1. Pick any saved chart. 2. Choose the day and time it goes out. 3. Add up to 20 recipients. Each gets a PNG to drop into a deck and a CSV to open in a spreadsheet. Your execs, contractors, and partners get the numbers on time without creating an account or asking someone to export them. **Availability line** Scheduled reports are included on Team and Business plans.

**CTA** Schedule a report ## Annotations - **Headline:** States the feature as a new ability ("Now you can send any saved chart to up to 20 people on schedule"), with the two hard numbers up front. - **Subhead:** The "no login needed" fact is the real differentiator, so it gets its own sentence instead of a trailing clause. - **Steps:** They mirror the actual setup flow you described, so there's nothing to invent. - **"PNG to drop into a deck / CSV to open in a spreadsheet":** This is my inference about use. Cut it if it doesn't match how customers use the files. - **Closing line:** Plain on purpose, with no tagline. The section ends on the plan note and CTA. ## Alternatives - **Option A:** "Email your saved charts to people who don't have a Pinpoint login." Rationale: leads with the differentiator, which suits a page aimed at teams who report to outsiders. - **Option B:** "Your Monday retention chart, in everyone's inbox before standup." Rationale: more vivid, but it assumes weekly sends and a specific chart. Use it only if both are true. ## Flags - `[NEED: recurrence options]` I kept the headline neutral because "day and time" doesn't say whether sends are weekly, daily, or monthly. If it's weekly, "every week" would sharpen the line. - `[NEED: proof]` There are no customer quotes or usage numbers here. A named customer saying what they replaced (manual exports, screenshots) would strengthen the section. - `[NEED: CTA destination]` Confirm whether "Schedule a report" goes into the product or to a plans page for visitors not on Team or Business.
without
## Scheduled Reports **Your metrics, in their inbox, right on time.** Pick any saved chart, choose a day and time, and Pinpoint emails it automatically. Each report arrives as a PNG you can drop straight into a slide or Slack thread, plus a CSV for anyone who wants to dig into the numbers. **Share with people outside Pinpoint** Send each report to up to 20 recipients. They don't need a Pinpoint login, so execs, clients, and cross-functional partners stay in the loop without another seat or password. **Set it up in seconds** 1. Open a saved chart 2. Choose a day and time 3. Add your recipients After that, the report sends itself. *Scheduled reports are available on Team and Business plans.* **[Schedule your first report →]**

The creator’s own tests

creator-1

“Write homepage copy for a SaaS tool that automates employee onboarding. Target audience is HR directors at mid-size companies (200-2000 employees). Main differentiator is that it integrates with all major HRIS systems and cuts onboarding time from 2 weeks to 2 days.”

creator-10

“Can you make this homepage hero better? I wrote it myself and it feels rough. Headline: Your agency doesn't need another dashboard. It needs to get paid. Subhead: We got sick of chasing clients for money, so we built the thing that does it for us. Invoices go out when the work ships. Late payers get nagged. You get your evenings back. CTA: Try it free”

creator-2

“Rewrite this headline: 'An Innovative AI-Powered Platform for Streamlined Business Operations' — it's for a B2B SaaS tool that helps small businesses manage invoicing and payments.”

creator-3

“i need copy for my pricing page. we have three plans: starter ($29/mo), pro ($79/mo), business ($199/mo). it's a social media scheduling tool for marketers”

creator-4

“Write copy for our About page. We're a 3-person startup that built a developer tool for database migrations. Founded because we kept losing data during migrations at our last jobs. Tone should be professional but human.”

creator-5

“Can you improve this CTA? We currently have 'Learn More' on our feature page for our analytics dashboard product.”

creator-6

“Write me a 5-email welcome sequence for new trial users of our project management tool.”

creator-7

“Review this copy and tell me what's wrong: 'We are extremely excited to announce our revolutionary, cutting-edge platform that will totally transform how businesses optimize their workflows! Sign up now!!'”

creator-8

“Write above-the-fold copy for a calendar scheduling tool. Our differentiator is that the recipient gets to overlay their own calendar on the invite, so picking a time feels fair to both people instead of one-sided. Same product needs to work for indie founders AND for enterprise ops teams.”

creator-9

“Write a homepage hero (headline, subhead, CTA) and a short launch post for X for our Shopify inventory app. It installs from the Shopify App Store in one click, needs no signup form or credit card, and runs low-stock alerts, reorder emails, and supplier purchase orders off the product and sales data the store already has, so there's nothing to import.”
