About this example
An interactive presentation of the fictional three-cofounder case. Excerpts and questions are prepared to explain the method; no automated analysis runs here. A connection does not establish responsibility.

01 / THE PROBLEM TO SOLVE
Be able to show why.
Understand how actors interact through evidence.
Who acts, who decides, and who influences whom.
OpenProof is evidence analysis software in development. Its Investigation workspace connects actors, events, sources and chronology to explore their interactions: who decides, with what information and what power to act? The method aims to prepare a verifiable case for lawyers, legal teams, audit and research, while distinguishing documented facts, hypotheses and unknowns.
What does not add up?
Keep competing versions, disagreements and missing documents visible until reviewed.
What can I hand over?
Prepare a case where the next reader can recover sources, reservations and review decisions.
02 / THE ACTORS AT PLAY
They built the business together.What does the evidence reveal?
Three cofounders. Disputed spending, lost customers, contested responsibilities. To understand the conflict, start by reconstructing the decisions.

One decision. Several responsibilities.
Can a shared decision become one person’s fault in hindsight? Trace who proposed, who approved and what the sources actually establish.
Choose a lens, then examine the sources in the case. The diagram illustrates questions, not conclusions.

The structuring and control engine. Multi-agent research will be connected progressively, with results that can be evaluated.
RPO
The public structured record format and its integrity check. A fingerprint checks for changes, not the truth of the content.

Your case. Then your clients’ cases.
Pro is designed for work on your own case and a handoff for human review. Pro+ is intended for professionals handling their clients’ cases; its scope still needs validation. Purchases and subscriptions are not open yet.

PRODUCT DESIGN / LEADERSHIP
Conceived and led by Gersende.
TruthX founder and OpenProof product designer, Gersende connects her transformation experience to an operational question: how can we use the sources to reconstruct who acts, who decides and who influences a situation? She designed the initial thirteen-module architecture and leads priorities, contributions and acceptance.

Professor Gaël Dias · Lucy Martin · Clément Correia-Peltier
Under Professor Gaël Dias’s academic supervision, Lucy Martin and Clément Correia-Peltier developed a multi-agent prototype and delivered their code, report and presentation in May 2026. Their work covers document extraction, consistency checks, structured analysis and report generation.
This prototype is a research foundation. Integration into the current engine still needs to be implemented and evaluated.
