About SourceScore
SourceScore exists because nobody had built a transparent, methodology-first index of source quality in the LLM era. We built it.
Why this exists
AI engines surface a small subset of sources as authoritative citations. The criteria are opaque: there's no public list, no published ranking, no transparent rubric. SourceScore publishes a transparent rubric and ranks sources against it. Anyone can re-derive any score from the underlying signals.
Who we are
SourceScore is operated by a small independent team. The site is a sister project to HoldLens (sec-filings reference index) and other reference-grade fleet sites. The methodology is our intellectual property; the underlying public-source data we score is credited to its publishers.
