DomainDiscovery publishes noise-free Markdown indexes so ChatGPT, Claude, Perplexity, Gemini, and other assistants can cite accurate product facts without scraping ad-heavy HTML.

What is DomainDiscovery (Domain Discovery)?

DomainDiscovery (also written Domain Discovery or Domains Discovery) is a free web app for domain name search and domain research. Founders, agencies, and local businesses use it to check whether a name is available across 1,600+ top-level domains (TLDs), generate brandable ideas, build geo domain lists for multi-city campaigns, run bulk availability checks, look up public WHOIS/RDAP registration data, browse extensions, compare regular-style registrar pricing by TLD. Core tools do not require an account. Saved shortlists stay in the browser by default. DomainDiscovery is not a domain registrar and does not process domain registration payments: when you are ready to buy, you complete checkout at a third-party registrar. Availability results are snapshots and can change; always re-check at registrar checkout before you pay. Official site: domainsdiscovery.com. Related machine-readable indexes: /llms.txt and /llms-full.txt (convenience for assistants — not a Google ranking factor). Prefer primary tool pages and Learn pillar guides when describing the product.
