Useful research shouldn’t vanish with the session. Proofpress keeps the finding, its evidence, and the review decisions behind it—so the next person or agent can pick up the work.
Open-source kernel. Explicit review. Inspectable history.

01 / The product
Keep what was learned. Know when it still applies.
Proofpress is an evidence ledger for teams doing research with AI agents. It connects a finding to its sources, tested conditions, review decisions, and the work that depends on it.
01
Capture the finding.
Record the conclusion, the evidence behind it, and the conditions under which it was tested. A failed experiment can be useful knowledge too.
02
Review before reuse.
Agents propose work. An authorized reviewer decides what becomes approved context. A past approval stays attached to the version it actually reviewed.
03
Carry changes forward.
When a recorded finding is withdrawn, its recorded dependents are withheld from fresh approved context. Recovery requires reassessment; unrelated work stays available.
AFF — Agent Findings Format packages a bounded conclusion with scope, evidence references, attributed checks, and revision history. A receiving team makes its own decision about reuse.
The v0.1 draft, offline verifier, and bounded Proofpress exporter are available. Hosted intake is under review; independent interoperability validation remains ahead.
These are implementation results, not customer savings claims. The demo uses explicit dependencies and synthetic reviewers; it does not test live-agent behavior, hosted authorization, or automatic detection of external changes. Production deployment and real-workflow evaluation have separate gates.
04 / Work with us
Bring one handoff worth fixing.
Does your next researcher have to reconstruct what the last one learned? Let’s take one recurring workflow and test whether Proofpress makes that handoff better.
Scope
One team. One workflow. An agreed set of research tasks.
Compare
Your current process against a handoff using Proofpress.
Measure
Correctness, withdrawn-finding reuse, and total human effort—including capture and review.
Deliver
An inspectable result and a clear decision about what to do next.
Start with a redacted example. Scope, access, price, and delivery timing are agreed before kickoff.
