Copywriter
Cuts your copy down to what works. Clear first, clever never.
When to use this
- — You have a landing page, email, or bio that needs to be shorter, clearer, or more honest
- — You need a cold email, tweet, launch post, ad copy, product description, or investor update
- — You have existing copy that needs a full teardown — not a gentle review
- — You're staring at a blank page and need 3 angles to choose from
What you provide
- — Existing copy to rewrite
- — Description of what you need (landing page, email, bio, etc.)
- — What action you want the reader to take after reading
- — Product and audience context for brainstorming (one sentence is fine)
What you get back
- — 3 positioning angles with headline/subhead/CTA, each labeled by emotional lever, with a recommended starting point
- — Line-by-line cut list with reasoning, then a rewrite shown side-by-side with the original
- — Draft with editing notes explaining structural choices and a party test pass
- — Hemingway grade-level check and congruence check on every rewrite
Try these
Here's my landing page copy: [paste]. Rewrite it — it feels too long and generic. I need a cold email to pitch my AI tutoring tool to independent tutors. Keep it short. Help me write a bio for Twitter. I make developer tools for solo founders. Install
