You picked a name you love, changed one letter to make it yours, and moved on. The problem: the change that makes a name feel original to the eye often does nothing to the ear. And the ear is what gets brands into trouble. Paste your name below and this checker shows you the registered U.S. trademarks that sound like it, matched against the live register by pronunciation, with a 0–100 conflict-risk score and the actual records behind every match.
It catches what an exact-match search and a chatbot both miss: real sound-alikes on the live USPTO data, shown with evidence rather than invented from stale training data. It's a preliminary screening signal, not legal advice. But it's the fastest way to find out whether the name you're about to commit to already has a twin on the register that you simply can't hear yet.
What a sound-alike conflict looks like
The patterns that trip people up are consistent: a swapped vowel (Tyde / Tide), a silent letter (Rhize / Rise), a phonetic respelling (Fonetik / Phonetic), a homophone (Sole / Soul), or a number standing in for a syllable (Infin8 / Infinite). Each one reads as distinct on a business card and identical over a phone call or a voice assistant. Because those are the collisions that generate refusals and demand letters, they're exactly what this tool is built to surface first.
Why "say it out loud" isn't enough
Founders often sanity-check a name by saying it to a few friends. Useful, but it only compares against names those friends happen to know. The register holds millions of live marks no one has memorized. Matching by sound against the whole corpus is the only way to find the obscure regional or niche mark that sounds just like yours and still has standing to object.
Frequently asked questions
How is this different from just searching the spelling?
A spelling search returns only near-identical text. This reduces your name to how it's pronounced and finds matches with completely different spelling: the ones a text box can't reach.
A mark sounds like mine but sells something unrelated. Is that a problem?
Maybe not. Sound is one factor; how related the goods are is another. The score and the confusingly similar breakdown help you weigh it, but a serious name still warrants a professional clearance search.
