Provenance is a free AI writing tool built by 15degreesnorth, adapted from Siqi Chen’s AI pattern research published under MIT licence in 2025. Chen’s work, drawn from Wikipedia’s Signs of AI Writing project, catalogued the specific linguistic habits that every major AI model consistently produces: the inflated vocabulary, the hollow conclusions, the em dashes, the sycophantic openers, the rule-of-three padding.
The standard approach: generate content with AI, publish it, hope nobody notices. Provenance: run it through 19 documented AI writing patterns, strip the machine fingerprints in a two-pass process, and get copy back that sounds like it was written by someone who actually knows what they are talking about.
Built specifically for B2B content teams where voice is a commercial asset, not an afterthought.
