Evidence-grounded document intelligence

Extract meaning from documents, not just text.

SignalExtract turns inconsistent PDFs, emails, and reports into structured, evidence-linked signals — findings, recommendations, amounts, and more — with a hybrid engine and human review you can actually trust.

LLM lock-in

Built for messy, real-world text

Reliability that single-pass LLMs can't match

Inconsistent formatting, ambiguous language, implied recommendations — handled by layering deterministic rules, LLM understanding, grounding, and review.

Evidence on every signal

Each extracted signal links back to a verbatim source span with offsets. No black-box outputs — claims that can't be grounded never survive review.

Hybrid by design

Deterministic rules and LLM understanding, merged. If the model is offline or over quota, rule-based extraction still delivers. Never dependent on one path.

Human-in-the-loop

Calibrated confidence routes uncertain signals to a fast approve, reject, or edit queue — so reviewers spend time only where it matters.

Structured & exportable

Typed signals with full provenance — document, page, span, method, confidence — exportable to JSON or CSV for any downstream system.

How it works

Recall first, precision second

Generate candidates broadly, then ground and verify strictly — the arc that turns inconsistent extraction into something you can ship.

“Rule-based was too brittle. Strict pipelines failed on variability. Basic LLM extraction was inconsistent. SignalExtract is the approach that works in practice — broad recall, grounded evidence, and review where it counts.”

The problem this was built to solve.
