BuildSeal — Signed records for AI systems

For teams building AI applications and agents

Signed decision records for AI systems.

When a decision is questioned, show what your application recorded. BuildSeal captures the decision, its reason and input references in a signed record that a reviewer can inspect.

  • Decision + reason + references
  • Signed evidence
  • Shareable verification link
FROM APPLICATION TO REVIEWER

A decision needs a record.

  1. 1Your application supplies the decision.
  2. 2BuildSeal creates the signed record.
  3. 3A reviewer opens the verification link.

See the actual checks for a real service record.

How it works

Capture. Seal. Inspect.

01 · Capture

Your application supplies the record.

Send the decision, its reason and relevant input references. Keep the context you need for a later review.

02 · Seal

BuildSeal signs the captured version.

The record is hashed and signed. A record ID connects it to the evidence workflow and its verification link.

03 · Inspect

A reviewer checks the evidence.

Open the link to inspect package integrity, signature, timestamp and record-binding results. Signer trust is shown separately.

Try the real service

See a record before integrating.

Explore a live memory write or create a record for a small file. Each flow links to the service records behind the result.

BuildSeal LIVE FILE RECORD

Try it with a file version.

Create a real record for a file version, then inspect the checks reported by the service.

Verification scope

Clear evidence. Explicit limits.

What the record can support

  • Detect changes to the captured content through hash checks.
  • Check a signature against the signing key.
  • Inspect the reported timestamp and record-binding checks.
  • Give a reviewer a stable reference to the recorded version.

What it does not establish

  • That a statement is true or a decision is correct.
  • That an external action happened as described.
  • That a signer is trusted merely because its signature is valid.
  • That a chain of records was checked by the public lookup.

The hosted page displays service-reported checks. Independent package verification requires a compatible verifier and an expected signer key.

Logging requirements and official references

Requirements depend on the system and its role. A signed record alone does not establish regulatory compliance. Refer to the European Commission for the current AI Act implementation timeline.

Pilot access

Bring one decision flow.

Tell us what your application decides, what evidence it captures and who needs to review it. We can discuss the record format, access and verification scope for a pilot.

Pilot access is arranged directly. Self-service accounts and API-key issuance are not yet available.

Advanced architecture

Records across memory writes and agent handoffs.

Explore the deeper mechanisms: recorded context and memory (VEDM), evidence assessment for write authority (A10), and commitment outcomes with separate proof finalization (A9).

Developer entry point

Access and deployment details

Keep API keys on your server. The browser demonstration uses a fixed demo actor. Configure storage, access, retention and sharing before submitting sensitive data.
