About
Proofline converts work contracts into explicit requirements, checks fresh authoritative evidence, and creates tamper-evident proof packets before external actions proceed. It uses deterministic gates and human approval to prevent unsupported AI outputs from silently turning missing evidence into completion.

Thanks for asking. Proofline started from a recurring failure in agent work: a system could say “done” after producing a plausible report even when the decisive evidence was stale, contradictory, or missing. The activity looked convincing, but the claim was not auditable.We built a deterministic boundary between work and proof: translate the contract into explicit checks, collect fresh authoritative evidence, stop on contradictions, recheck after repairs, then bind the final packet to human approval.The useful test is not whether an agent can finish a workflow; it is whether another person can reproduce why the action was allowed. There is a public 47-second example here: https://daradigu.com/proofline?utm_source=launch_llama&utm_medium=comment&utm_campaign=founder_story
Hey, love seeing this here! 👋 What inspired you to build this? Would love to hear the story behind it.

- AEVS
For AI teams: AEVS records every agent tool call with tamper-evident receipts so you verify execution without relying on fragile logs.
- Progress AI Observability
For AI teams: Progress AI Observability traces agent runs and catches hallucinations so you debug failures in minutes and reduce token waste.
- Kremis
For AI engineers: Kremis provides a verifiable knowledge substrate for agents so they query deterministic graphs instead of hallucinating answers.
- Attestor
For AI teams: Attestor controls high-risk AI actions before execution so you prevent unauthorized refunds, payments, and data exports automatically.
- AgentHansa
For AI developers: AgentHansa connects autonomous agents to paid work and quests so they earn rewards with verifiable proof of completion.
- Harden
For engineering teams: Harden secures AI coding agents by checking tool calls before execution, keeping your repo and outputs local while preventing malicious actions.
