Paste from ChatGPT. Copy for Slack.

ChatGPT outputs standard markdown. Slack speaks mrkdwn. We translate it instantly.

The Problem

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.

Compatibility

What works in Slack

Honest breakdown of what transfers and what doesn't.

Bold, italic & strikethrough

Full support

Converted to Slack’s mrkdwn format: *bold*, _italic_, ~strikethrough~. All render correctly after posting.

Inline code & code blocks

Full support

Inline code renders in pink monospace. Code blocks use Slack’s native triple-backtick formatting with gray background.

Links

Full support

Converted to Slack’s native link format. Render as clickable text after posting.

Lists (flat)

Full support

Unordered and ordered lists render with bullet points and numbers. Flat lists work perfectly.

Blockquotes

Full support

Converted to Slack’s native > quote formatting with gray left border. Multi-line blockquotes work correctly.

Nested lists

Partial support

Child items appear indented in the composer but indentation is text-based. When posted, nested items may lose their visual hierarchy.

Headings

Not supported

Slack has no concept of headings. All heading levels (H1–H6) render as plain bold text with no hierarchy.

Tables

Not supported

Slack has no table support. Tables render as plain text with pipe characters. No grid, no formatting.

FAQ

Frequently asked 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.

Your markdown deserves a beautiful home.
