Audit and rewrite marketing copy to strip unverified claims
A dual-agent system scores landing page, cold email and pitch deck copy against strict rubrics, then rewrites it to remove fluff and unsupported claims.
Done with a custom-built or unnamed agent
- What they did
- The builder made two agents on gpt-4o-mini with low temperature and fixed seeds. The evaluator scores copy against mode-specific rubrics (landing page, cold email, pitch deck) and caps Specificity at 7/10 when no verifiable metrics exist. The rewriter is forbidden from strengthening claims, turns unproven percentages into defensible outcomes, and strips Markdown.
- How it went
- The source is a launch post and reports no results or numbers from real use. It invites users to try to bypass the guardrails and gives brutal feedback, with 5 free credits on sign-in.
- Worth knowing
- A hidden watermark in the rewritten text stops users re-auditing already optimized copy and wasting credits; credit deductions use Firestore transactions to avoid race conditions.
Try it yourself with Claude Code
Read my marketing copy in [file path for landing page, cold email, or pitch deck]. Score each section against a strict rubric: every claim must be specific and verifiable, with no fluff, superlatives, or unsupported numbers. Then write a revised version that removes or flags every unsupported claim, and give me a table of what you changed and why.
