What the DeepSeek assignment checker does
This tool reads coursework and reports the patterns typical of DeepSeek's writing, with each signal named and explained rather than compressed into a single score. It exists for a specific, pre-submission question: does my own assignment carry the reasoning scaffolding and phrasing habits of DeepSeek, and where exactly.
It's a server tool by necessity. The pattern model is too large to run in a browser, so the assignment is sent to our AI server to be scored, and the result is returned to the page. You get 5 free checks in any rolling 24 hours, no account required.
The output is a list rather than a percentage. A checker that returns a bare number is asking for unearned trust; this one names each pattern (leftover step markers, exhaustive checklist-style coverage, a restated prompt) so the reasoning is available for inspection rather than taken on faith.
