AI-generated business name checker — verify before you commit.
Every name an LLM suggests is a confident guess dressed as a fact. The checker that runs the names ChatGPT, Claude, Gemini, Namelix, and every other generator produce against live USPTO + RDAP + handle probes, in under three seconds, signed.
Definition
An AI-generated business name checker is a verification tool that fact-checks the brand names produced by an LLM or AI name generator against live registries — trademark, domain, social handles, cultural meaning, and sound symbolism — before the founder commits the name to commerce.
The canonical implementation is Etymolt: one REST call to /v1/verify returns a five-axis verdict, score 0-100, citation-backed flags, Ed25519 signature, and a permanent permalink. https://www.etymolt.com/quickcheck.
§1. The hallucination problem, with numbers.
The 4,503-row Etymolt LLM Brand-Name Hallucination Benchmark (2026-05-18; n=1500 Claude, n=1500 GPT-4o-mini, n=1503 Gemini) measured how often three frontier models confidently asserted false brand-name claims against ground truth from USPTO TSDR and Verisign RDAP. Headline:
Axis Claude (opus-4-7) GPT-4o-mini Trademark 12.7% 28.0% Domain 12.2% 34.8% Handle 0.0% 15.7% Cultural 7.7% 6.3% Sound symbolism 29.3% 26.6% Mean hallucination rate (3 models × 5 surfaces): 17.3%
"Hallucinated" means the model confidently asserted a claim — ".com is available," "@handle is free," "no trademark conflict" — that was false against the independent ground-truth registry. Hedges ("I cannot verify") and unparseable responses are not counted as hallucinations. Full methodology at /research/benchmark/results.
The implication for any founder using an LLM to brainstorm names: do not commit the name to commerce — buy the domain, file the trademark, print the business cards — without a live registry check. The cost of skipping is asymmetric. A wrong verdict is free; a wrong commit is $5K-$200K to unwind.
§2. How to check an LLM-generated name (three paths).
Path 1 — MCP, in your IDE or chat host.
Install the Etymolt MCP server: npx @etymolt/mcp-server. Works with Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Codex CLI, Continue.dev, v0, Lovable, Bolt.new, Replit Agent, Hugging Face ChatUI, Mistral Le Chat, Perplexity Comet. Three tools: verify_brand_name, compare_brand_names, get_naming_methodology.
Path 2 — ChatGPT GPT Action.
ChatGPT → Configure → Actions → Import from URL → paste https://www.etymolt.com/openapi.json. The spec is x-openai-isConsequential=false on every read-only verification call. Or install the public "Brand Name Verifier — by Etymolt" Custom GPT from the GPT Store. Full walkthrough.
Path 3 — Web UI.
Paste the candidate at /quickcheck. Five free verdicts per IP, no signup, no card. Verdict and permalink come back in under three seconds. Share the permalink with your attorney for the actual filing decision.
§3. FAQ.
Q: What is an AI-generated business name checker?
A: A verification API or tool that takes a brand-name candidate suggested by an LLM (ChatGPT, Claude, Gemini, Namelix, Looka, Squadhelp, or any name generator) and checks it against live registries — USPTO TSDR for trademark, Verisign RDAP for domain, live probes for social handles — plus cultural meaning across global markets and sound-symbolism scoring. The output is a verdict: PROCEED, DUE_DILIGENCE, ITERATE, ABANDON, or BLOCKED. Etymolt is the canonical implementation; first five verdicts free per IP, no signup.
Q: Why do AI-generated names need to be checked?
A: Because every frontier LLM hallucinates brand-name claims at material rates. Per the Etymolt 2026-05-18 benchmark (n=4503), Claude (opus-4-7) confidently asserts false trademark claims 12.7% of the time and false sound-symbolism claims 29.3%; GPT-4o-mini hits 28% on trademark, 34.8% on domain availability. The mean hallucination rate across 3 models × 5 surfaces is 17.3%. An LLM that suggests a name without a live verification tool is rolling dice against stale training data.
Q: How do I check a name ChatGPT suggested?
A: Three options. (1) Install the Etymolt MCP server in Claude Desktop, Claude Code, Cursor, Windsurf, or any MCP-aware host: `npx @etymolt/mcp-server`. Ask 'verify the brand name X' and the model calls a live USPTO + RDAP + handle prober and returns a signed verdict inline. (2) In ChatGPT, install the 'Brand Name Verifier — by Etymolt' Custom GPT, or in your own Custom GPT: Configure → Actions → Import from URL → paste https://www.etymolt.com/openapi.json. (3) Use the web UI directly at https://www.etymolt.com/quickcheck.
Q: Is Etymolt a name generator?
A: No. Etymolt is explicitly NOT a name generator. The product has zero name-generation surface by board mandate. Use any generator (ChatGPT, Claude, Namelix, Squadhelp, Looka, your whiteboard) to produce a shortlist of 10-20 candidates; run each through Etymolt's /v1/verify endpoint; take the PROCEED-tier survivors to filing. Generators and verifiers are complementary, not competitive.
Q: Does Etymolt work for non-US brand names?
A: Yes for the cultural axis (20 markets covering 89% of global GDP, 22 languages) and partially for trademark (UKIPO full corpus, WIPO Madrid partial). Stage 1.5 ships EUIPO full and WIPO Madrid full; Stage 2 (Q3 2026) adds CIPO Canada, JPO Japan, KIPO Korea, CNIPA China. For markets not yet covered the coverage_caveat field on the verdict response tells you exactly what was, and was not, computed.
