What the Llama research paper checker does
This tool reads a section of a research paper and reports the phrasing habits specifically associated with Llama's academic writing, named and explained rather than compressed into one score. Because Llama is an open-weight model that reaches people through many different fine-tunes and front-ends rather than one hosted product, its output varies more than a single company's assistant, but a flatter, more generic register and occasional prompt-echoing wording still recur often enough to check for.
It is a server tool by necessity. The pattern model doing the scoring is too large to run in a browser, so the text is sent to our server, forwarded to the model for the run, and the result returned. Nothing from that run is stored afterward. Each check accepts between 1 and 12,000 characters, and you get 5 free checks in any rolling 24 hours.
The output is a list, not a percentage. A checker that returns a bare number is asking for unearned trust; this one names each pattern so the reasoning stays open to inspection rather than taken on faith.
