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.

Same request, same model, once with the skill and once without. Read both and judge for yourself.

“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.”

with the skill
**A: This is a brief-led draft, with HRIS compatibility and the two-week-to-two-day improvement as the core argument.** I’ve used `[Product]` as the name and assumed the primary CTA is booking a demo. # Homepage copy ## Hero ### Two weeks of onboarding. Done in two days. Automate employee onboarding with [Product]. Built for companies with 200–2,000 employees, it integrates with all major HRIS systems and cuts onboarding time from two weeks to two days. **CTA: Book an onboarding demo** Keep your current HRIS. ## Problem ### Your next hire shouldn’t mean another two-week process Every new hire starts another round of onboarding work for HR. When that process takes two weeks, it competes with everything else your team needs to get done.

[Product] automates employee onboarding so you can shorten the process and give your team time back. ## Integration ### Keep the HRIS you already use You’ve invested in your HRIS. [Product] integrates with all major HRIS systems, so you can add onboarding automation without replacing it. Bring your existing system to the demo. We’ll walk through how [Product] fits. **[Insert a verified HRIS integration logo strip here.]** ## Outcome ### Make two-day onboarding your standard Reduce onboarding time from two weeks to two days. Give HR directors at growing, mid-size companies a shorter process to manage as new employees join. **[Insert a customer example showing the two-week baseline, two-day result, and what “onboarding time” measures.]** ## Final CTA ### See how two-day onboarding could work at your company Tell us which HRIS you use and how onboarding works today. We’ll show you where [Product] fits. **CTA: Book an onboarding demo** --- ## Key copy choices - **Lead with the time reduction:** It gives HR directors a concrete reason to consider changing their process. - **Put HRIS compatibility in the hero:** It addresses a likely implementation concern before visitors need to scroll. - **Keep the draft focused:** Task assignments, reminders, compliance workflows, and other features aren’t specified, so they haven’t been invented. ## Alternatives ### Headlines - **Cut employee onboarding from two weeks to two days.** The clearest, most direct version. - **Two-day onboarding. Your existing HRIS.** Gives the outcome and integration benefit equal weight. ### CTAs - **See [Product] in action** — best if the demo is primarily a product walkthrough. - **Book a demo for your HR team** — emphasizes the intended audience. ## Before publishing The draft uses both claims supplied in your brief. Support the **two-week-to-two-day claim** with a documented customer result or representative dataset that defines the start and end of onboarding. If it reflects one customer’s experience, attribute it rather than presenting it as a universal result. Support **“all major HRIS systems”** with a current integration directory and clear coverage criteria. Until verified, the narrower alternative is: “Integrates with [verified HRIS names].” **SEO title:** Employee onboarding automation | [Product] **Meta description:** Cut employee onboarding from two weeks to two days with [Product]. Integrates with all major HRIS systems for companies with 200–2,000 employees.

“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.”
