Open five competitors' homepages side by side and the same words stare back from every tab: fast, easy, powerful, built for teams like yours, trusted by thousands. Yours says it too. Every company in the category has independently arrived at the same sentence, and the buyer comparing them has no basis to choose. It's a positioning problem wearing a copywriting costume, and rewriting the same claim more elegantly won't fix it. Doing it right means reading every competitor page closely, extracting what each actually claims underneath the adjectives, tabulating the overlap, and finding the claim that is both true of you and unoccupied. That's an afternoon per round, so it gets done once at founding and never again — even as the category shifts underneath.

Paste your own copy alongside what up to four competitors publish about themselves and get the whole set laid out — the claims everyone makes and are therefore worth nothing, the ground nobody has taken, and the specific lines in your own copy that could belong to any of them, quoted back at you. Every conclusion is built only on the text you paste, never on what a model thinks it remembers about a company. No monthly platform fee, no usage cap, full white-label PLR rights.

P2 tier: ANTHROPIC_API_KEY is REQUIRED. The generate route returns a 'Set your API key in .env.local' message and NEVER silently falls back to demo data. A user-initiated 'See a sample teardown' button renders seed/examples.json client-side, clearly labelled as sample output — a preview only, never wired into the API route.

• Pro upgrade — Full preset library, roster batch mode across all 25 comparison sets, and priority export formats — skip the setup and teardown at agency speed.
• Agency — Client-use rights, agency onboarding pack, and done-for-you vertical presets with the tired claims and live tensions per category — one set per client.
• Done-for-you — Ongoing drop of new vertical preset packs, refreshed sameness/whitespace references, and copy variants as categories shift — recurring amount, interval, first renewal date and cancellation stated before the button.
