+Meeting transcripts, AI-generated notes, action items, and coaching feedback from Grain's meeting intelligence platform.
+
+### Query Patterns
+
+**Meeting search:**
+- Use `list_attended_meetings` or `list_meetings` to discover recent customer-facing calls, strategy sessions, and brand planning meetings
+- Use `search_in_transcripts` for query terms: "brand", "positioning", "messaging", "value prop", company name, product name
+- Use `search_persons` / `search_companies` to surface meetings with marketing leads, executives, agency partners, or specific customer accounts
+
+**Transcript and notes retrieval:**
+- `fetch_meeting_transcript` returns the full timestamped transcript
+- `fetch_meeting_notes` returns Grain's AI-generated summary, which often surfaces brand-relevant themes already extracted
+- `fetch_meeting_action_items` surfaces commitments and decisions — frequently the source of brand-positioning shifts
+- `fetch_meeting_coaching_feedback` (where available on the workspace) surfaces patterns around message effectiveness
+
+### Tips
+- Grain captures both AI-generated notes and full transcripts — notes are higher-density signal for brand themes; transcripts are higher-fidelity for voice/tone analysis
+- Cross-reference Grain meetings with Gong or Granola when multiple sources are connected — the same call may appear in different systems with different summaries
+- Attended meetings (calls the user was in) carry first-person source authority for brand decisions
+- Recurring meeting series (weekly customer calls, design-partner syncs, strategy sessions) are high-yield for brand evolution
+- Coaching feedback (where surfaced) reveals which messaging frames consistently land or fail
