must be proven.
Probandum is case-building software for legal matters: state your claims, attach your evidence, and keep custody that holds. Every fact gets a receipt.
A matter holds the positions you carry the burden for — assertions first, paper second.
Every exhibit links to a claim with its polarity — and its reasoning on the record.
The letter that lands today meets the case you are building tonight.
A refuting document moves your claim the moment it is read — before you could have looked.
Agents suggest supports and refutes with reasons; you confirm, edit, or invalidate.
Original reasoning is preserved verbatim. Edits never overwrite judgment.
Support, ranked. Attack, ranked. Gaps, exposed — per claim, always current.
Every claim carries a live standing — a derived balance, never a hand-wave.
Append-only, hash-chained events follow every artifact from first capture to exhibit.
Each capture is timestamped onto Bitcoin — independent of us, and of anyone.
Where it came from, what read it, when it landed — one click from every claim.
Gmail and IMAP connectors file what matters the moment it arrives.
Fax-quality PDFs run through vision readers; every field becomes searchable.
Verbatim key-values stay in the record, so search never goes blind on the details.
Claims, ranked evidence, exhibit list, custody proofs — one deliverable.
Tax files, insurance disputes, HR investigations — the burden of proof is universal.
Where evidence lives and who controls its storage is surfaced — never hidden.
Isolated trust domains per matter — no cross-linking, no cross-leakage.
