- Does Slack support full Markdown?
- No — Slack uses mrkdwn (Slack's variant). *bold* (one asterisk), _italic_, ~strike~. Different from CommonMark. This tool translates.
- What about Discord?
- Discord supports a larger subset — closer to standard Markdown but with its own quirks (spoilers, @mentions). Toggle between Slack and Discord modes.
- Are code blocks preserved?
- Yes — both platforms support ``` fenced blocks. Language hints are dropped (neither platform does syntax highlighting).
- What doesn't convert?
- Tables, task lists, and images with URLs. Slack and Discord don't support these; the tool either strips them or shows a text representation.
