Ask the assistants your buyers already ask — ChatGPT, Claude, Gemini, Perplexity, DeepSeek — the questions they type when they are choosing. SeenByLLMs counts where your brand shows up, ranks you against the names you compete with, and hands you a report you can send to a client.
Run a check No account, no server. Your OpenRouter key stays in your browser.
Here are the options I would look at first.
Paste an OpenRouter key, or connect with their OAuth flow. Set a spend limit on the key first.
Brand, domain, the other spellings of your name, and up to five competitors.
Write the questions, or let SeenByLLMs suggest twenty buyer questions. Edit them before you run.
Mention rate, average rank, share of voice and win rate, the sources the models cited, the questions you are missing from, and what to do next — as a one-file report or a CSV.
Monthly $12, or lifetime $49 for the first 100 buyers (then $79). You still pay OpenRouter for the model calls. A 20-question run on the five default models is about $0.30.
$12/month
$49
Early-bird for the first 100. Then $79 once.
In this browser. SeenByLLMs has no server and no account. Export the report before you switch machines, because nothing syncs.
The key is stored in this browser's local storage and is sent to OpenRouter and nowhere else. Nothing is proxied through us, because there is no us to proxy through. Give the key a spending limit so a mistake cannot cost more than you meant.
Score = round(100 × (0.5 × mention rate + 0.3 × share of voice + 0.2 × rank score)), where rank score is 100 for first place down to 0 at sixth or worse. Failed calls are left out of every number. The formula is published because the other tools in this market keep theirs secret.
Plain text matching on your brand name, the aliases you listed, and your competitors. It costs nothing extra and the same answer always scores the same way. Ranking reflects the order companies first appear in an answer.
Web search is on by default: each question is sent with OpenRouter's openrouter:web_search
tool, so answers come back with the pages behind them, and every source is labelled by what kind of
site it is — your own, a competitor, a review site, a forum, or editorial. It costs about $0.007 per
request on models that do not search natively, billed by OpenRouter to your account. Turn it off and
the answers come from the model's memory, with no sources to show.
They are different models with different training data and, for some, different search results. That disagreement is the finding. A brand that only Gemini names has a different problem from one that nobody names.
