Paste from ChatGPT.
Copy forSlack
ChatGPT outputs standard markdown. Slack speaks mrkdwn. We translate it instantly.
Slack mangles your markdown into raw symbols
You copy a ChatGPT response to share in Slack, and the formatting is wrong. Double asterisks instead of bold, hash marks sitting in the message, tables breaking into unreadable pipe characters.

Bold, italic & strikethrough
Full supportConverted to Slack’s mrkdwn format: *bold*, _italic_, ~strikethrough~. All render correctly after posting.
Inline code & code blocks
Full supportInline code renders in pink monospace. Code blocks use Slack’s native triple-backtick formatting with gray background.
Links
Full supportConverted to Slack’s native link format. Render as clickable text after posting.
Lists (flat)
Full supportUnordered and ordered lists render with bullet points and numbers. Flat lists work perfectly.
Blockquotes

Nested lists
Partial supportChild items appear indented in the composer but indentation is text-based. When posted, nested items may lose their visual hierarchy.
Headings

Tables
Not supportedSlack has no table support. Tables render as plain text with pipe characters. No grid, no formatting.

Questions?
Copy the ChatGPT response, paste it into Unmarkdown™, click "Slack", then paste into your Slack message. The markdown is converted to Slack’s native mrkdwn format so bold, code, and links all work correctly.
ChatGPT uses standard markdown (double asterisks for bold, # for headings). Slack uses its own format called mrkdwn (single asterisk for bold, no headings). Unmarkdown™ translates between the two automatically.
Slack has no table support. Unmarkdown™ converts tables to a readable plain text layout so the data is still clear, but there’s no grid or cell structure in Slack messages.
No. Unmarkdown™ runs 100% in your browser. Your ChatGPT responses are converted locally and copied to your clipboard. Nothing is ever sent to any server.
