Pesura
Trust & preventive-health infrastructure for EdTech AI

The Trust Layer
for AI Agents in Education

Pesura records what your AI agents do, checks every decision, and stops harm before it reaches a student.

Think of it as preventive care for your AI agents: we keep the record, spot problems early, and shield students before damage happens.

The Problem

AI agents now make decisions about students. No one can show why.

Agents grade exams, flag proctoring sessions and recommend learning paths. When a parent or a school asks "why did the AI do this?", ordinary logs can't answer.

—Why did the agent make this decision?
—What data did it use, and which tools did it call?
—Where did a human step in?
—Can we prove what happened?

How Pesura Works

Record → Diagnose → Protect → Improve

01

Record

Every action an agent takes is captured step by step in a tamper-evident, hash-chained trail.

02

Diagnose

Every decision is scored for quality. Errors are categorized, and trust scores move with evidence.

03

Protect

A policy shield checks actions before they run: block, require human approval, or log.

04

Improve

Recurring problems become clear recommendations for your product and engineering teams.

Everything you need to trust AI

Agent Identity

Every agent gets a stable, verifiable identity and an owner.

Verifiable Evidence Trail

Tamper-evident, hash-chained events you can inspect and audit.

Decision Verification

Every recorded action is digitally signed (Ed25519). Recompute hashes and verify signatures at any time to confirm a record is authentic and unchanged.

Policy Shield

Rules that block or pause risky actions before execution.

Independent Audit Log

Every shield decision is recorded in its own tamper-evident log, separate from the agent's trace.

Trust Scores

Transparent, rule-based scores and integrity alerts.

Founder

Built by a former teacher.

I spent twenty years as a teacher. Every grade I gave had evidence behind it, and if a parent asked why, I could put it on the table. AI agents in education should be held to the same standard. That's why I built Pesura.

Gülşah Demir, Founder

Education has always run on evidence.

Make your AI agents accountable, auditable and verifiable.

Pesura provides structured evidence, cryptographic integrity mechanisms, verification and investigation workflows. It is not a legal determination, universal safety certification, or proof of an AI's internal reasoning.
