Score any domain on four research-backed dimensions: Cognitive Fluency, Sound Character, Brand Signal, and Extension Intelligence. Discover your sound archetype and phonetically similar billion-dollar brands.
The Domain First Impression Test scores any domain name across four research-backed dimensions: Cognitive Fluency, Sound Character, Brand Signal, and Extension Intelligence. Each dimension is worth up to 25 points for a total of 100. Enter a domain and get an instant overall score, a verdict, your sound archetype, and the billion-dollar brands your name is phonetically similar to.
Cognitive Fluency measures how quickly the human brain processes your domain name, drawing on research by Alter & Oppenheimer (2006) showing that easier-to-process names are trusted sooner and recalled more accurately. Sound Character classifies your domain into one of five phonetic archetypes -- Bold, Warm, Sharp, Playful, or Enigmatic -- using phonosemantic research by Sapir (1929) and Ramachandran & Hubbard (2001). Each archetype maps to real-world billion-dollar brands with similar phonetic profiles.
Brand Signal evaluates whether your domain name is Invented, Abstract, Suggestive, Descriptive, or an Exact Match -- and explains why the most valuable brands in the world (Apple, Nike, Stripe) chose names with zero product keywords. Extension Intelligence scores your TLD choice against sovereign risk data from Grails' proprietary extension risk database, flagging geopolitical, policy, and operational risks that could affect your domain's long-term viability.
Results include a shareable score card you can download as PNG or share to Twitter/X with a pre-composed tweet. The scoring methodology section cites every peer-reviewed paper used in the analysis. Whether you are choosing a domain for a new venture, evaluating a rebrand, or preparing for a funding round, this tool gives you the research-backed first impression your domain makes.

The tool scores your domain across four dimensions -- Cognitive Fluency, Sound Character, Brand Signal, and Extension Intelligence -- each worth up to 25 points for a total of 100. The methodology draws on peer-reviewed research in phonetic symbolism, cognitive fluency, and brand naming theory.
Sound archetypes classify your domain's phonetic character into one of five categories: Bold (hard consonants, short), Warm (soft sounds, approachable), Sharp (crisp, cutting), Playful (repeated sounds, bouncy), or Enigmatic (invented, mysterious). Each archetype maps to real-world brands with similar phonetic profiles.
Scores above 75 indicate a strong first impression across all four dimensions. Scores between 50 and 74 are solid but have room for improvement. Below 50 suggests the domain may be creating friction with visitors, investors, or customers.
Brand Signal measures whether your domain is Invented, Abstract, Suggestive, Descriptive, or an Exact Match for your industry. Research shows that invented and abstract names (Apple, Nike, Stripe) score highest because they leave maximum room for brand expansion.
Extension Intelligence scores your TLD (.com, .io, .ai, etc.) against Grails' proprietary sovereign risk database. It evaluates geopolitical stability, policy risk, security incidents, and operational reliability of the country or organization that controls your extension.
Yes. The tool includes a copy-link button, a Twitter/X share button with a pre-composed tweet, and a Download PNG button that saves your score card as an image you can share anywhere.
