Plannotator launches visual review for AI agents

Plannotator is an open-source visual interface for reviewing and refining AI agent outputs, including code changes and research paper analysis. It intercepts agent-proposed plans, allowing users to annotate text and provide structured feedback that agents use to iteratively improve their results.

// ANALYSIS

Plannotator formalizes the human-in-the-loop process for autonomous agents, turning "black box" execution into a collaborative review workflow.

–Visual diffs and line-level annotations offer far more precision than simple conversational feedback for complex agent tasks.
–Native support for Claude Code, Gemini CLI, and Copilot CLI makes it a versatile utility for leading terminal-based agents.
–Local-first architecture with E2E encrypted sharing provides a secure environment for enterprise-ready agent experimentation.
