Simon Willison built a single-purpose browser tool that strips the '❯' prompt character and fixes wrapped-line whitespace from text copied out of the Claude Code terminal app.
The problem is specific: Claude Code terminal output pastes with formatting artifacts that make copied prompts unusable without manual cleanup. This tool runs entirely client-side, takes the raw paste, and outputs clean text with a one-click copy button.
It is a narrow fix for a narrow problem, but the implementation details, including how it detects and rejoins wrapped lines, are worth examining if you build tools around terminal output parsing.
