How Nombrio checks name viability

What “viability” means here

A name can be available as a domain and still be a poor name to build on — already taken as a trademark, unusable on social, or confusingly close to an existing brand. Nombrio runs a first-pass screen across the signals that decide whether you can launch on a name, then summarizes them as one viability score. Whether you bring your own name or have Nombrio generate options, every candidate runs through the same checks.

Every name gets one 0–100 viability score that summarizes observed risk and practical usability across the live checks below. Trademark risk carries the most weight — it’s the hardest blocker to undo, so a real conflict caps the score low no matter how clean everything else looks. Crucially, a check we couldn’t complete (an outage, a rate limit, a registry we didn’t run on your plan) never counts as “clear” — it lowers our stated confidence, never inflates the number. Each score shows how many signals we actually verified, so you always know how complete the picture is.

A name that is already someone’s product can’t read “strong” either. If an iOS app already uses the exact name, or our web scan finds an existing business using it in your space, the score is capped below 80 even when no trademark is registered — prior use in the market is a real conflict the registries don’t show. The gauge tells you which finding caused the cap, so the headline never contradicts the checks beneath it.

Running a Clearance Check on a finalist from a Naming Session reuses that session’s profile, cached checkers, and score inputs — so the number you see on /analyze matches the one on your results page unless something has genuinely changed since, which we label “changed since <date>” rather than showing a silently different score.
