A macOS menu bar app that helps developers collect context from the frontmost app (GitHub, GitLab, Jira, Linear, Slack, Notion, Confluence, docs, and web pages) with ⌃ ⌘ C, then paste one clean brief into coding agents with ⌃ ⌘ V.
- Captures context from the frontmost selected app or browser tab, including page content beyond what is currently visible.
- Cleans and densifies raw captures into a high-signal context your coding agent can use immediately.
- Lets you build one context from multiple snapshots, then paste the compiled result into any LLM or coding agent.
