Source Detection Patterns

Use these patterns to identify document source types from plain text content.

Detection Priority

Check patterns in this order (first match wins with high confidence):

1. Zoom transcripts (most distinctive patterns)
2. Slack conversations
3. JIRA tickets
4. Confluence/wiki pages
5. Email threads
6. Meeting notes
7. General notes (default)

Zoom Transcript

High confidence indicators (any 2+ = zoom):

• WEBVTT header at start of file
• Multiple speakers with consistent formatting

Medium confidence indicators (supporting evidence):

• Phrases: "you're on mute", "can you hear me", "let me share my screen"
• "unmute", "muted", "screen share"
• Time-based speaker transitions

Example patterns:

WEBVTT

00:00:15.000 --> 00:00:20.000
