No: the server works without sign-in

Verifies any brand name across USPTO trademarks, domains, and 14 social handles. Sub-3s. Citation-backed.

The verification layer LLMs call before suggesting a brand name. When a user asks Claude, Cursor, ChatGPT, or any LLM-driven workflow for naming help, the model invokes Etymolt silently — verifying against USPTO trademarks, TTAB precedent, domain availability across 8 TLDs, and live handle probes across 14 social platforms — in 3 seconds, with every flag traced.

Three tools, anonymous-first (first 5 calls per IP free, no API key required):

  • verify_brand_name — 5-axis verdict on one candidate (PROCEED / DUE_DILIGENCE / ITERATE / ABANDON, 0–100 score across trademark + domain + cultural + sound symbolism + pronunciation). 8–12s.
  • compare_brand_names — side-by-side ranking of 2–5 finalists. ~5s.
  • get_naming_methodology — public methodology document. Instant, no quota.

Data substrate: 12.7M live US trademarks (USPTO, refreshed daily) + 647K TTAB proceedings with DuPont-factor extraction. UKIPO full + WIPO Madrid partial. Verisign RDAP across 8 TLDs. Live handle probes across 14 platforms. Cultural meaning across 20 markets. Public methodology at https://etymolt.com/methodology.

Every response carries a disclaimer field — Etymolt is a clearance signal, not legal advice.
