Naming a business usually stalls in the same place: a long list of words nobody has screened, and no idea which ones can actually be owned. This prompt turns Claude or ChatGPT into a business naming specialist that generates candidates by name type, tells you which ones will be misspelled the moment they are said out loud, and cuts the names that are too generic to protect.
Paste the prompt into a Claude Project, a ChatGPT custom GPT, a Gemini Gem or a plain chat, say what the business sells and where it will trade, and answer five brief questions. You get eighteen to twenty five labelled candidates, a spelling verdict on each, a shortlist of five with the exact domain, handle and search checks to run, a language and culture screen, and the trademark warning in plain words. It works with Claude, Claude Code, ChatGPT, Gemini and Copilot.
Free tool: try the free AI business name generator first, then use this pack for a screened shortlist you can actually own, with the domain, handle and trademark checks spelled out.
Domain Name Ideas and Availability Check
A follow-up prompt turns your five shortlisted names into a ranked list of exact domains to check, and a short checklist tells you how to confirm them yourself at a registrar.
-
Extensions that fit: the exact .com first, country codes for the markets you trade in, and .ai, .io or .app only when the business really is an AI or software product
-
Smart variants: prefix and suffix patterns (get, try, hq, app) and location words, each rated for whether it keeps or weakens the brand
-
Variants to avoid: hyphens, number swaps and spellings that differ from how the name is said
-
You confirm availability: Claude never claims a domain is free; you check at a registrar, look up taken domains and re-rank the shortlist on what you confirmed
