Humanly: A Configurable and Traceable Environment for Human-AI Collaborative Writing
For educators and evaluators, Humanly offers a configurable, traceable environment to verify authorship in human-AI collaborative writing, addressing the problem of indistinguishable final text.
Humanly is a writing platform that records the entire writing process, including AI assistance, to provide verifiable evidence of authorship. A user study confirmed its usefulness across roles, and a red-teaming study showed its typing detector can distinguish human typing from automated typing.
Teachers, conference chairs, and public readers all judge writing from limited evidence, seeing only a finished document and not the process that produced it. Final text alone cannot reveal whether a document was produced through human typing, AI generation, or mixed human-AI collaboration. Existing process-tracking tools help, but many are tied to host-document histories, provide coarse activity records, and offer limited control over the writing environment. Humanly is a writing platform that makes the writing process itself the evidence. Users configure writing environments for personal documents or assigned tasks and draft in a workspace that records writing activity and in-platform AI assistance. Humanly can package a completed session into a sealed writing certificate with configuration-aware anomaly behavior review. It can support writing scenarios such as course assignments, peer review, and personal certification. Our user study shows that Humanly is helpful across roles, and a red-teaming study shows that the Humanly Typing Detector distinguishes human hand typing from automated typing.
