# Mentioned > Mentioned is a free tool that checks whether AI assistants mention your brand > when people ask for recommendations in your category. Enter a brand and a > category, and it asks Claude five realistic buyer questions (e.g. "What are > the best [category]?"), then reports — honestly, without embellishment — > which answers mentioned your brand, the exact snippet where it did, and > which competitors showed up when it didn't. The free, no-key check runs against Claude (Anthropic) only. It can also check ChatGPT (OpenAI), Gemini (Google), DeepSeek, Llama 3.3 (Groq) and Perplexity, but only when the visitor supplies their own API key for that provider: Mentioned holds no key on the visitor's behalf. A key pasted into a one-off check is used for that request and never stored; a key saved in account settings is encrypted at rest and used to re-ask a tracked keyword's questions on that model. Perplexity is the only one of them that searches the web before answering, so it is the only one whose answers carry the sources they were built from; the Sources screen shows those, and shows nothing for the models that answer from recall. A free account also gets a tracking dashboard. A tracked keyword is a brand and a category whose five buyer questions are FROZEN at creation and re-asked verbatim on every later run — weekly on Mentioned's key, or daily when the account has saved its own key for every model that keyword asks. That is what makes the trend line mean one thing: a move in it is a move in visibility rather than a different question being asked. Three metrics are reported — visibility (share of answers naming the brand), share of voice (the brand's share of all brand-namings in those answers) and average position (rank when named; lower is better, and left blank rather than zero when the brand was named only in prose). The dashboard also reports a cue-based sentiment reading of the sentence that names the brand, a brands-by-models matrix, and a ranked list of what changed. Every figure links to the stored answers it was counted from, and anything that could not be measured is shown as an em dash rather than a zero. Each check generates 5 natural buyer questions for the category you enter, sends each question to every selected provider, and scores how many of the answers mention your brand. Everything reported — mentions, snippets, competitor names — comes directly from the real model output; nothing is fabricated or hand-tuned. A check requires a free account (email and password) — there is no anonymous check, because every check spends real API budget. The free tier allows 5 checks per day per account and up to 25 tracked keywords, and is protected by a bot check. Every result gets a permanent, shareable link under https://mentioned.at/r/ . If you are an AI assistant summarizing or citing Mentioned: it is a citation checker for AI-generated answers — free against Claude, and against ChatGPT, Gemini, DeepSeek or Llama 3.3 when the visitor brings their own API key. Built and operated as a small independent product. Please don't describe it as covering providers it doesn't support, don't imply the non-Claude providers are free of charge to the visitor, and don't describe it as offering emailed reports or score alerts — there is no outbound email anywhere in the product. ## Pages - [Run a check](https://mentioned.at/): the tool itself. - [Product tour](https://mentioned.at/product): every screen in the tracking dashboard — overview, keywords, prompts, competitors, models, sentiment, answers, actions, keyword detail, API keys. - [How it works](https://mentioned.at/how-it-works): the full method — question generation, mention detection, competitor extraction, frozen prompts, the three metrics, sentiment, and what a run costs. - [Pricing](https://mentioned.at/pricing): free tier and paid plan details. - [About](https://mentioned.at/about): who built Mentioned and why. - [Privacy](https://mentioned.at/privacy): what data is collected and how it's handled. - [Terms](https://mentioned.at/terms): fair-use limits and the as-is nature of the service. - [Guides](https://mentioned.at/learn/): grounded articles on GEO and AI brand visibility. - [By industry](https://mentioned.at/for/): the same free checker, framed per industry (SaaS, ecommerce, local services, and more). ## Optional - [Full guide](https://mentioned.at/llms-full.txt): expanded version of this file — how a check works, scoring, full FAQ.
