About Markagent

Markagent is a privacy-first UI/web feedback annotator that captures screenshots, highlights UI elements, records user journeys, and produces one-ready Markdown artifacts you can drop into AI agents. Use it to leave notes tied to DOM/UI sources, copy annotations as Markdown, export CSV, and generate prompts compatible with Claude Code, Codex, Cursor, OpenCode and similar agents. Runs locally as a Chrome extension — no account, zero telemetry, and free forever.
