ReportArk is a delivery and review platform for HTML reports generated by AI agents. It allows agents to publish a finished HTML file and receive a single browser link to share with teammates for review. Reviewers can pin comments directly to headings, tables, charts, or specific findings within the report. The agent can then read that anchored feedback in its next run, enabling precise, context-aware revisions. ReportArk also supports access controls, password protection, and version updates without changing the report link.
