Some of these tools are built specifically for domain brainstorming, others are general-purpose word tools that happen to be useful for coming up with names.
Domainr
The best tool for finding domain hacks and creative TLD combinations. Type in a word and it instantly shows available options across hundreds of TLDs, including synonyms. Fast and smart.

Namecheap Bulk Domain Search
Enter a word and check availability across 1,000+ TLDs at once. Activate “beast mode,” select all TLDs, and hide unavailable domains. This is how I found handle.horse and followup.fish.

AI Chatbots
Tools like ChatGPT, Claude, and Grok are great for generating keywords, synonyms, and word associations related to your industry. Give them a few example words and ask for more — they’re surprisingly good at surfacing terms you wouldn’t think of.
OneLook
More than a dictionary. You can search for words that start or end with specific letters — useful when you’re trying to find words that work with a particular TLD.
