PlainText for Claude is a Windows system-tray utility that squishes multi-line, indented text from Claude or any AI assistant into a single clean, paste-ready line — no more broken URLs, commands, or file paths.
If you use Claude Code, ChatGPT, or any AI assistant in a terminal, you've hit this: the AI spits out a URL or a command, and your terminal wraps it across multiple lines with leading whitespace. You select it, copy it, paste it into a browser or another terminal — and it doesn't work. There are line breaks in the middle, spaces that shouldn't be there, and the whole thing is broken.
This is different from the formatting-stripping problem that PlainText solves. That tool removes HTML and RTF formatting from copied text. This tool fixes the structural problem — text that got split across lines and indented by a terminal emulator.
PlainText for Claude monitors your clipboard. When it detects multi-line text with leading whitespace on continuation lines — the telltale sign of terminal-wrapped output — it collapses everything into a single line. Newlines are removed, leading and trailing whitespace on each line is trimmed, and the result is a single unbroken string. Paste normally with Ctrl+V.
You copy this from Claude Code's terminal output:
PlainText for Claude turns it into:
One line. No spaces. Ready to paste into a browser.
PlainText for Claude is free and open source. It requires Python 3.10+ on Windows 10 or 11.
