🧹 Cleanup Claude Code Paste — The Tiny Tool Every Claude Code User Needs

Ever copied text from Claude Code's terminal and ended up with a mess of broken lines, rogue ❯ symbols, and bizarre whitespace?

You're not alone. Simon Willison — the creator of Datasette and one of the most respected voices in the developer tooling space — ran into this exact frustration. His solution? A dead-simple web tool called Cleanup Claude Code Paste.

Here's what it does:

• Strips out the ❯ prompt characters that cling to every pasted line
• Fixes whitespace artifacts caused by terminal line wrapping
• Rejoins broken lines into clean, readable paragraphs
• One-click "Copy to clipboard" for instant use

The workflow is effortless — paste your messy terminal output into the input box, and the cleaned version appears instantly below. No sign-up, no install, runs entirely in your browser.

Willison himself calls it a "super-niche tool," but if you're among the growing number of developers who live inside Claude Code daily, this small utility saves real minutes of manual cleanup every single day.

Sometimes the best tools aren't the biggest — they're the ones that remove just enough friction to keep you in flow.
