Export Chat History to Markdown/Notion Integration

[crazygo]

Is your feature request related to a problem? Please describe.

Currently, valuable information from AskMan chat conversations cannot be preserved long-term. Users need a way to export insightful conversations for future reference and knowledge management.

Describe the solution you'd like

Add two export options to AskMan:

1. Markdown Export

• Export button/command to save conversation as .md file
• Include metadata (date, participants)
• Preserve formatting (code blocks, lists, etc.)

2. Notion Sync

• One-click sync to Notion
• Auto-create new page in specified database
• Maintain chat structure and formatting
• Optional: Add tags/properties for better organization

Describe alternatives you've considered

• Manual copy/paste (inefficient, loses formatting)
• Screenshot (not searchable/editable)
• Browser extensions (unreliable, security concerns)

Additional context

This feature would improve knowledge retention and make AskMan more valuable for long-term learning and reference. Similar features exist in tools like Discord and Slack, proving their utility.
