Finds out why the AI says "busy". It sends a tiny test message ("reply OK") to each AI model with your key and tells you, in plain words, which ones work. Your key is sent only to Google, from this page on your own computer. It is never saved or sent anywhere else.
Takes about a minute. Nothing here costs money beyond a few words of AI use.
Step 2 — Realistic test the real job
Step 1 only sends one word. This sends a full sample CV and job posting and asks for the full CV + cover letter, exactly like the app does, and times it. It shows whether slow "thinking" or the size of the request is what goes wrong. Takes about 2–5 minutes — keep this tab open.
