Drop a borrower's file into AI and get back a clean pre-approval letter on your letterhead — NMLS line, the "not a commitment to lend" language, and the disclosures a compliant letter needs. No blank page, no re-typing the same three paragraphs. Two ways to run it: • On a paid Claude plan? Install the free Mortgage Broker plugin and type /pre-approval-letter. One command, done. • Any other AI — free Claude, ChatGPT, Gemini? Copy the built-in prompt (a sample borrower is prefilled), paste it in, swap your numbers. Inside: the full prompt with sample borrower, the one-command Claude path, built-in compliance rails, and a two-minute setup walkthrough. Opens in your browser. AI writes a fresh letter every time — read it before it goes out. The compliance rails keep it on track, not replace your review. Want the rest of your week handled — rate comparisons, refinance analysis, borrower updates? The Loan Officer AI Prompts pack is the full system: 58 ready-to-run skills. This free tool is a real slice of it.
