TrustDoc is an AI-powered document management and evaluation platform. Teams upload documents, compare them against approved templates, and let AI score each submission, generate written justifications, and summarize content — turning slow manual review into an auditable, repeatable workflow.
Upload, analyze, and retrieve documents in a few clicks, with AI reviewing each file against your approved headers and templates instead of relying on manual spot-checks.
Generate consistent numerical scores for every submission so reviewers and stakeholders can compare documents objectively rather than relying on gut feel.
AI writes the reasoning behind each score, giving you an audit trail that explains why a document passed or fell short, which is especially valuable in compliance contexts.
Standard and premium plans condense long documents into digestible summaries, so reviewers can triage a large batch quickly before reading in depth.
