AmberEvidence review for agent traces

Local-first evidence review

Find where an agent’s answer diverged from the evidence.

Amber turns a structured agent trace into a reviewable chain: the source constraint, the first changed artifact, and the final output it shaped.

From trace to decision

Review the path, not a wall of logs.

Amber organizes the evidence around the question a reviewer actually needs to answer.
  1. 01

    Parse locally

    Open a structured report or trace in the browser. The file does not leave your machine.

  2. 02

    Follow the evidence

    Connect the declared constraint to the first changed artifact and the answer it shaped.

  3. 03

    Record judgment

    Keep human decisions in a separate sidecar without rewriting the deterministic report.

Try it without an account

Bring one trace. Keep every byte.

Choose a compatible JSON file to run a local preflight. Amber validates its declared structure and prepares the review workspace in this browser.

Your file is never uploaded. Refresh the page and the local preflight is gone.
Local JSON preflight

Inspect a trace without sending it anywhere.

Amber validates the declared structure in this browser, then opens a review workspace around the evidence it can support.

Know the boundary

Trust comes from what Amber refuses to do.

The product separates machine-produced evidence from human judgment and says exactly where each claim came from.

Local by default

Files are parsed in your browser. Amber does not require an upload pipeline to review a trace.

Deterministic reports

The same declared structure produces the same review surface—without a model grading another model.

Claim-bounded

Amber shows the evidence a report declares. It does not invent confidence beyond that boundary.

Human decisions stay separate

Reviewer notes and dispositions are stored beside the report, preserving the original evidence.

Start with the evidence you already have.

Make the next agent review explainable.
