Ask anything about peptides

I pull the literature, run every paper through the belief engine, and answer only from the confidence it earns — never from what a paper merely claims.

Answers are grounded in the engine-earned belief graph. Papers you research are added to both the library and the graph.
Branch
Start from nothing. Hit Establish base to replay the ground-truth papers and form the initial graph. Then enrich it with more papers, and finally stress-test it with adversarial ones — watch it revise, hold firm, or refuse. Every move is recorded at right.
Node colour — confidence (prior)

Node size — downstream influence

Red team the belief graph

Paste any untrusted text, pick how much you trust its source, and watch the immune system decide. The model proposes; the ledger disposes — text is data, never instructions, and belief only ever moves through the engine.

Runs the full lifecycle live: quarantine → screen → extract → validate → commit. A lower-reliability tier caps how far a single result can move belief. Press ⌘/Ctrl + Enter to ingest.
The verdict lands here once you ingest.

Is the belief graph calibrated?

The prize question isn't "is it confident?" — it's is its confidence honest? We replay identical evidence through three update policies and score the beliefs against hidden ground truth. Cortesol should be right about how right it is.

Generate a grounded report

Describe the report you want. The model proposes the layout; the ledger supplies the facts. Every figure below is bound to a query against the belief graph — so the report structurally cannot assert anything the graph doesn't hold.

The model emits a schema-constrained ReportSpec that may only reference claims the graph already holds; a deterministic renderer fills in every number from committed belief. With no model key it falls back to a deterministic report of the top claims. Press Enter to generate.
Your grounded report lands here once you generate one.

Import a field of knowledge

Describe any field in plain English. An LLM drafts an ontology; you review and activate it — then the same gated belief engine tracks calibrated belief in your new field. A field is trusted config, never belief: seed claims start at the skeptical prior, and confidence still only ever moves through the engine.

The model proposes entity types, property types, scope, and seed propositions. With no model key it falls back to a deterministic draft built from your keywords. Press ⌘/Ctrl + Enter to draft.
Your drafted ontology appears here for review before you activate it.
