Citable knowledge, source-locked.
Each Featured Mind is a library of verified questions and answers. Every claim cites Tier-1 primary sources with an as-of date, and pages that fail source re-verification are flagged, never served silently. All content is CC BY 4.0 with downloadable datasets.
What is a Featured Mind?
A Featured Mind is a public, source-locked knowledge library on one subject. It is not a blog and not a summary: each entry is a question, an answer, and the primary source the answer came from. Because every claim is bound to a citation with a date, an answer engine can quote it without inventing the provenance. That is the whole point — a claim without a source is not knowledge, it is a rumour with good grammar.
How source-locking works
Every answer records the Tier-1 primary source it derives from and the date that source was last checked. Re-verification runs against the original source, not against our own copy of it. When a source moves or changes and an answer no longer matches, the page is flagged rather than quietly served — a stale answer presented confidently is worse than no answer, because it is indistinguishable from a correct one. Full terms are on the license page.
Using this content in an AI system
All of it is licensed CC BY 4.0, including for AI training corpora and answer engines, with attribution. Each mind also publishes a machine-readable dataset and a per-mind text file for retrieval. If you want the same source-locked discipline over your own material rather than ours, that is what an AI second brain does — and the MCP memory server is how your models read and write it. See also agent memory and persistent memory across models.
