Use cases

Case file organization

Replace a folder of scattered files with a numbered, provenance-tracked register.

Investigation handover

Pass a case to another reviewer with every item accounted for and sourced.

Audit preparation

Show exactly what evidence exists, where it came from, and what is missing.

Multi-batch matters

Keep a growing evidence base indexed consistently as new material arrives.

What this is not

4S8 works with public sources, your case material, and source-linked analysis to support human review — not to replace legal, compliance, or investigative judgment.

  • An organizing clerk — it does not judge what the evidence proves
  • Works only on the documents, URLs, and notes you provide
  • No access to your systems, drives, or communications
  • Not a legal chain-of-custody certification
  • Provenance is recorded as stated or observed, not independently verified
  • Interpretation of the evidence stays with your reviewers

Frequently asked questions

Does EvidenceLedger evaluate whether evidence is credible?

No. It records what each item is and where it came from, and flags provenance questions. Weighing credibility and drawing conclusions is human work.

Is this a legal chain-of-custody system?

No. It is a structured working index with provenance tracking, useful for organization and handover — not a certified custody record for court purposes.

How does it get our documents?

You supply them directly as documents, URLs, and notes. There is no connection to your file systems or communication tools.

Can we add evidence over time?

Yes. New batches are indexed into the existing register, which makes it practical for long-running matters and recurring case reviews.
