Plannotator releases inbox interface for human review and annotation of AI agent work outputs

Plannotator launched an inbox-based interface for humans managing multiple concurrent AI agents, using an email-like metaphor to surface agent questions, blockers, and work products requiring review. The tool enables humans to review and annotate agent-generated code, designs, and prototypes asynchronously while agents continue execution, with annotations delivered as the next session turn. The interface supports Markdown, HTML, Mermaid, and Graphviz annotation formats.
