This tool is free and always will be. There is no sign-up, no account, and nothing you enter is stored or sent anywhere except directly to Anthropic's API to produce your report. Your CV, the advert, your notes, and your key live only in your browser for this one session and vanish when you close the tab.

One thing up front: nobody can tell you for certain why you were rejected, and this tool will not pretend to. It gives you the most likely reasons given what is visible, ranked by probability, and it is honest about how often rejection has nothing to do with you. Use it to aim your energy, not to beat yourself up.

What you'll need: an Anthropic API key

The tool runs on Anthropic's Claude. You bring your own key so the cost is yours and tiny. Setup takes about five minutes.

1. Go to console.anthropic.com and create an account (or sign in).
2. Add a little credit under Billing. The minimum is usually $5, far more than you'll need. It's a pre-paid balance, not a subscription.
3. Open API Keys, click Create Key, name it, and copy it. It starts with sk-ant-.
4. Paste it below. It stays in your browser only.

What a report costs

Roughly 10 reports per US dollar. A $5 balance covers around 50 to 70 reports. You can set a monthly spend cap in the console. Prices are approximate and set by Anthropic, not by me.

The thinking behind this tool

This tool distils two books. If it helps you, the books go far deeper, and buying one is the only thing I'll ever ask in return.
