| Documentation support | Comments only, limited formatting | Rich text, headings, tables, links, lists |
| GitHub integration | Displayed as raw code | Renders beautifully in GitHub READMEs and wikis |
| Code blocks | Plain SQL statements | Syntax-highlighted code blocks with language tags |
| Schema visualization | CREATE statements only | Formatted tables showing columns, types, constraints |
| Comments and annotations | Limited to SQL comment syntax | Rich annotations with markdown formatting |
| Team collaboration | Requires database knowledge to read | Accessible to all team members, technical and non-technical |
| Use case | Database development and queries | Documentation, README files, API schemas, team knowledge sharing |
