Check and clean marketing copy before you publish

Have one agent grade your copy against a strict rubric and another remove claims it cannot back up.

What they did
A builder wired together two agents and kept them deterministic with low temperature and fixed seeds. The reviewer handled landing pages, cold emails, and pitch decks with separate scoring rules, and it would not let specificity climb above 7/10 unless there were verifiable metrics. The writer then produced a revised version that avoids strengthening claims, converts shaky percentages into safer language, and strips Markdown.
How it went
The launch post shared no outcome data from live use. It says the tool gives harsh feedback, includes 5 free credits after sign-in, and uses a hidden watermark so already-cleaned copy is not run through the process again by accident.
Tips
Use a mode-specific rubric so the review matches the format you are editing. Add a pause before any action that would send, publish, or otherwise commit the text.

Try it yourself with Claude Code

Take my draft at [file path] for a [landing page / cold email / pitch deck]. Review it section by section with a strict rubric: mark any claim that is vague, unverified, or padded with fluff, and keep the specificity score capped at 7/10 unless I provide hard evidence. Then rewrite the draft so every line stays defensible, removing unsupported percentages, hype, and Markdown, and list the edits in a table with the reason for each one. If the next step would send, submit, or publish anything, stop first and ask me to approve it.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
