How it works

Paste the claim you need to support. The classifier detects the claim type - statistical, scientific, medical, policy, financial, technical, historical or opinion - and returns the four source archetypes that carry the most weight for that category. Each archetype ships with a pre-built Google, Scholar and Bing query with the right site: filter baked in.

Why match archetype to claim

  • Claim-weighted authority. Retrieval layers use different trust models per claim type - a .gov beats a newspaper for stats but not for narrative.
  • Primary over secondary. Every archetype here points at primary sources, not aggregators, so your citation chain stays short.
  • Query pre-scoped. The site: operators cut the search space to the sources that actually matter.
  • Tier visibility. The Tier 1/2/3 rating tells you whether this claim deserves a premium source or whether a trade pub is enough.

Pair with

Once you have a source, run it through the Citation Builder to format it, the Evidence Block Generator to wrap the claim, and the Trust Signal Analyzer to verify the overall page carries enough weight. Deep dive: how AI assistants choose citations.
