Who wins the AI answer; you or them?
One buyer question, four AI engines, head to head. We query each provider’s API once and score which of the brands you enter, yours plus up to three competitors, gets named in the answer and cited in the sources. The headline share is a mention share (the portion of answering engines that name each brand); citations are counted and shown separately. That’s your AI share-of-voice for that question; a single-run snapshot (engine answers vary run to run; tracked, repeated runs give the reliable trend).
What is Competitive Citation-Share Checker?
The Competitive Citation-Share Checker is a free, bring-your-own-key tool that runs one buyer question through Claude, ChatGPT, Gemini, and Perplexity and scores which brands, yours against up to three competitors, each engine names in its answer and cites in its sources. The headline share is a mention share, the portion of answering engines that name each brand, with citations counted and shown separately, side by side for that question.
How it works
You enter a buyer question, your brand and domain, and up to three competitors, then add an API key for any engine you have. The tool queries each provider's API once and checks every brand against both the answer text (named) and the returned sources (cited).
It shows each brand's mention share, its citation count separately, and each engine's actual response. Add a domain for any brand to measure its citations; without one, that brand's citation status shows as not measurable.
Keys travel over HTTPS for the single request and are then discarded, never logged or saved.
Who it’s for
For marketers, SEO and GEO teams, and founders who suspect a rival owns the AI answer for their money questions; the outcome is a concrete head-to-head read, who wins each buyer question today, so you know exactly where content work will move share.
In practice
An agency owner enters "best CRM for a small agency," their brand, and two rivals; three of four engines name a competitor and none cite the owner's site, so they now know which question to target, and the pages they publish get re-checked here until the share flips.
Questions, answered.
Yes, the tool itself is free; you bring your own API key for the AI runs it performs.
Yes, this is a bring-your-own-key tool. Your API key is sent over HTTPS to NYFTY's server only to make the request(s) for that single run, is never logged or stored, and is discarded immediately after.
It compares the AI engines available in the tool at the time you run it. The same buyer question is tested across those engines so you can see which brands are named and cited in each answer.
It outputs a head-to-head report for one buyer question, comparing your brand against up to 3 competitors. The headline percentage is a mention share; the share of the answering engines that named each brand. Citations (whether an engine returned that brand's domain as a source) are counted and shown separately, since a brand can be named without being cited. Use it to spot who is winning the answer and where your visibility gaps are.
Named means the AI answer mentions the brand in its response. Cited means the answer includes a source or reference connected to that brand, which is usually a stronger signal than a mention alone.
AI answers can change because models, retrieval results, prompts, and source availability can vary between runs. Treat the report as a snapshot for research and comparison, not a guarantee that your brand will appear, rank, or be cited in future AI answers.
