Paste from Gemini. Copy for Slack.

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

The Problem

Slack mangles your markdown into raw symbols

You copy a Gemini response to share in Slack, and the formatting doesn’t work. Gemini’s markdown syntax doesn’t match Slack’s mrkdwn format, leaving broken formatting in your message.

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 Gemini response, paste it into Unmarkdown™, click "Slack", then paste into your Slack message. Gemini’s markdown is converted to Slack’s native mrkdwn format automatically.

Gemini uses standard markdown (double asterisks for bold, # for headings). Slack uses a different format called mrkdwn (single asterisk for bold, no headings). Unmarkdown™ translates between the two.

Slack has no table support. Unmarkdown™ converts tables to a readable plain text layout. The data stays clear, but there’s no grid or cell structure in Slack messages.

No. Unmarkdown™ runs 100% in your browser. Your Gemini responses are converted locally and copied to your clipboard. Nothing is ever sent to any server.

Your markdown deserves a beautiful home.
