What Startup Name Spell Checker does

Startup Name Spell Checker, also called The Radio Test, is a free brand-validation tool from VNTA. It checks whether people can spell your startup or product name correctly after only hearing it spoken aloud. The idea comes from a classic marketing problem: if a listener types flicker.com instead of flickr.com, you leak organic traffic to the wrong domain or get buried in search results.

How it works

You type a candidate name and click Run Spelling Test. The tool analyzes the name and flags potential issues such as spelling ambiguity, pronunciation blocks and verbal confusion before you commit to buying a domain. It also ships with pre-loaded example names, including Slack, Flickr, Klaviyo, Xero, Scribd and Stripe, each labeled Easy or Confusing so you can compare your name against known cases.

Spelling ambiguity: highlights names that can be typed several plausible ways.
Pronunciation and verbal confusion: surfaces names that are hard to say or easy to mishear.

Who it is for

The tool is aimed at founders and marketers evaluating a name before a domain purchase. Public information about the underlying scoring method is limited, so treat results as a quick sanity check rather than a definitive verdict; the final decision stays with you.
