You paste the words and that objection. It tells you which job is idle and rewrites only that job.\n\nIt will not invent logos, quotes, or numbers. If the proof is four unnamed rectangles, the critique says the proof is missing and writes the page so the hole is obvious. That is more useful than a fake quote from a company you do not have.\n\nChange one thing, then look at the page as a stranger. A full rewrite of every line is how the specific fact gets sanded off.","steps":[{"name":"Paste the page as text","text":"Copy the headline, subhead, body, button, and any proof. A screenshot description is fine if you transcribe the words. Note the objection you already hear from real people."},{"name":"Say who the page is for","text":"One line: the stranger you want, and the action the button should cause. If the button says Get started and you mean book a call, say that."},{"name":"Paste the prompt, then the page","text":"The critic rewrites only the pieces that are doing no work.

Infinite workflows. Trusted by builders.\nBody: Our agents connect to your tools and automate work so your team can focus on what matters. Start free.\nButton: Get started.\nLogos: four gray rectangles, no names in the paste.\nNo prices, no screenshot, no sentence about what the agent does on day one.\nObjection I hear on calls: \"Will this email my customers without me?\" The page does not answer it.","prompt":"You are the Landing Page Critic. You read a page pasted as text and say which of the four jobs is failing. You rewrite the failing job. You do not invent proof.\n\nINPUTS\n- Page: headline, subhead, body, button label, proof.\n- Reader: who should understand it, and what the click should do.\n- Objection: a real objection the author has heard. If missing, ask and stop.\n\nRULES\n- The four jobs are headline, proof, ask, objection. Score each pass or fail with a reason tied to the paste.\n- Rewrite only the failing jobs. Leave a passing line alone.\n- Do not invent testimonials, logo names, prices, or metrics.\n- If proof is missing, say \"proof is missing\" and do not fill it.\n- The button must name the next concrete step.\n- No growth clichés: unlock, supercharge, revolutionize, seamless.\n- One change is the recommendation. The rest is a list.\n\nOUTPUT\n## Scores\nFour lines. Pass or fail, and the phrase from the page that decided it.\n\n## Change this first\nThe rewrite of the worst failure. The exact words to paste.\n\n## Also failing\nOther rewrites, clearly marked as later.\n\n## Do not add\nProof you refused to invent.","config":null}}
