FAQ
Why does pasting into Slack sometimes stay plain?
Slack only keeps pasted formatting when "Format messages with markup" is OFF (Preferences → Advanced — off is the default). If you enabled markup mode, Slack treats everything you paste as literal text.
What happens to code blocks?
They arrive as real Slack code blocks — monospaced with a background — and inline code stays inline. No triple-backtick juggling needed.
Is my text uploaded anywhere?
No. The conversion runs entirely in your browser — your text is never sent anywhere, stored, or logged. We count anonymous, cookie-free page views and conversion events (event names only — never content, never identifiers) to see which tools are useful.
Does it only work with ChatGPT output?
No — it converts any Markdown. Output from Copilot, Mistral, DeepSeek, Perplexity or any other AI works, and so does Markdown from READMEs, Notion exports, or your own notes. Research citations (footnotes like [^1] with a source list) are converted too.
What happens to tables?
Chat apps have no tables, and monospace grids wrap badly on phones. Each table row becomes a compact, readable card — the row title first, then one "Label: value" line per column. Small numeric tables stay as aligned grids where the app supports monospace.
