Evidence-first document Q&A

Answers you can verify

Gnosis answers questions from an authorized document collection — and shows the exact passage, revision, and physical page behind every claim. When the documents don't answer, it says so.

The demo runs on a curated corpus in your browser — no account needed.

The evidence workflow

Ask with an explicit scope; inspect what actually supports the answer.

1. Ask with scope

Choose all current documents or an explicit selection. An empty selection never silently means everything.

2. Retrieve and fuse

Lexical and semantic candidates are rank-fused, optionally reranked, and budgeted — with every candidate recorded.

3. Validate claims

Strict mode checks each material claim against the retrieved passages before anything is shown.

4. Inspect the source

Citations open the exact stored passage with document revision and physical PDF page — never a paraphrase.

Honest outcomes, not confident guesses

Missing evidence is reported as missing evidence — never as "the fact is false."

Answered

Every material claim carries a valid reference to authorized evidence, or it is qualified or removed.

Partially answered

When documents cover only part of the question, the answer says exactly which part is missing.

Conflicting sources

When revisions disagree, both statements are shown with their revisions — no invented resolution.

Insufficient evidence

If nothing in scope answers the question, the result says so — even when retrieval returned passages.

Version-aware, by design

Source revisions are immutable; answers remember the snapshot they used.

Immutable revisions

Uploading a replacement never overwrites the bytes or evidence of the previous revision. A failed replacement never breaks the working one.

Safe activation

A new index build becomes searchable only after its checks pass — until then, queries keep using the active build snapshot.

Observable execution

Every run records stages, timings, candidates, and outcomes. Diagnostics show what happened without exposing private content.

Portfolio project — scope and limits

Gnosis is built for small technical teams consulting documentation and runbooks: text-bearing PDFs, English retrieval, workspace-scoped access. It is not an autonomous research agent and does not guarantee that every answer is true — it guarantees that you can inspect the evidence behind each claim.
