Only 16% of AI-generated brand names pass a live domain availability check

A solo founder running a rebranding sprint tested 187 AI-generated names across four naming strategies and found just 30 — about 16% — had available .com domains. The core problem identified is that AI generates names based on meaning and language patterns, but has no visibility into domain registries, creating a loop of appealing names that are already owned. To break the cycle, the team automated live RDAP domain checks so every candidate was flagged as available or taken before anyone reviewed it. Descriptive names performed worst with a 6.5% availability rate, while metaphor-based and audience-mirror strategies each cleared roughly 25–27%. The winning name ultimately came from the audience-mirror round, where real phrases used by the target audience were fed back to the AI as raw naming material.
