What the AI research paper checker does
This tool reads a section of a research paper and reports the writing patterns shared across AI chat tools generally, each signal named and explained rather than compressed into one score. It is scoped to a paper's own register: an abstract that oversells its contribution, a method section written in oddly uniform sentences, a results paragraph hedged in both directions before it commits to a reading of the data.
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 (a scene-setting opener, symmetric hedging, uniform sentence length) so the reasoning is available to inspect rather than taken on faith.
