What the Gemini research paper checker does
This tool reads a section of a research paper and reports the phrasing and formatting habits specifically associated with Gemini's academic writing, named and explained rather than compressed into one score. Gemini's formal register tends toward structured, scannable formatting even where continuous prose is expected: a discussion that collapses into a bulleted list, bolded key terms scattered mid-sentence, and an introduction that restates the research question almost verbatim.
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.
