Granola Performance Tuning

Overview

Optimize Granola output quality across three dimensions: audio/transcription accuracy, AI enhancement quality, and integration speed. Granola's AI (GPT-4o/Claude) produces better output when it has clean audio, well-typed notes, and structured templates.

Prerequisites

  • Working Granola installation with meetings captured
  • Willingness to improve audio setup and meeting practices
  • At least 3-5 meetings captured to establish baseline quality

Instructions

Step 1 — Optimize Audio for Transcription

Granola captures system audio from your device. Transcription accuracy depends entirely on audio quality:

Hardware recommendations (by priority):

SetupAccuracy ImpactRecommendation
Wired headset with micHighestBest for solo/remote meetings
USB condenser micHighBest for in-office, multiple speakers
Laptop built-in micMediumAcceptable for quiet environments
Bluetooth headsetVariableMay cause dropouts — test first
Speakerphone in roomLowEcho and distance degrade accuracy

Audio configuration checklist:

  • Correct input device selected in System Settings > Sound > Input
  • Input volume at 75-100% (not too low, not clipping)
  • Audio enhancements disabled (Windows: right-click device > Properties > disable enhancements)
  • No conflicting virtual audio software (Loopback, BlackHole, etc.)
  • Bluetooth device stable (or switch to wired if experiencing drops)

Room setup:

  • Minimal background noise (close doors, turn off fans)
  • Soft surfaces to reduce echo (avoid glass-walled conference rooms)
  • Mic within 12 inches of speaker(s)
  • Meeting participants using headsets (reduces echo and crosstalk)

Step 2 — Improve Meeting Practices

These behaviors directly improve Granola's output:

PracticeImpactWhy It Helps
State names when assigning workHigh"Sarah, can you handle the API spec?" enables correct attribution
Use explicit action languageHigh"Action item: review by Friday" — AI detects structured language
One speaker at a timeHighCrosstalk confuses speaker diarization
Summarize decisions verballyMedium"So we've decided to go with option B" — AI captures decisions
Spell technical terms first timeMedium"We'll use Kubernetes, K-U-B-E-R-N-E-T-E-S" — improves accuracy
Type notes during the meetingHighYour notes give the AI critical context for enhancement
Brief recap at meeting endMedium"To summarize, we agreed on X, Y, and Z" — improves summary

Step 3 — Optimize Templates for AI Quality

Template structure directly affects the quality of enhanced output:

High-quality template design:

## Summary
[2-3 sentence overview of the meeting]

## Key Decisions
[Bullet list of decisions made, with reasoning]

## Action Items
[Format: - [ ] @person: task (due date)]

## Open Questions
[Items that need follow-up or weren't resolved]

## Next Steps
[What happens after this meeting]

Template optimization tips:

  1. Use 5-7 sections max — too many sections dilute content
  2. Include format hints[Format: - [ ] @person: task] guides the AI
  3. Put Action Items near the end — AI processes sequentially, actions at the end capture the full meeting
  4. Add "Verbatim Quotes" section for customer calls — AI will pull exact language from the transcript
  5. Avoid generic sections — "Notes" and "Discussion" produce vague output; be specific

Step 4 — Post-Meeting Quality Review (5 Minutes)

After enhancing notes, spend 5 minutes on quality assurance:

  • Summary accurate? Does it reflect what actually happened?
  • Action items complete? Are all commitments captured with correct owners?
  • Decisions correct? No hallucinated decisions or mixed-up attributions?
  • Sensitive content? Remove anything that shouldn't be shared before posting
  • Missing context? Add background the AI couldn't know

Step 5 — Use Granola Chat to Fill Gaps

After enhancement, use Chat to improve the notes:

"What did Mike say about the timeline?"
→ Searches transcript for Mike's statements about timeline

"Were there any disagreements that aren't captured in the summary?"
→ Analyzes transcript for conflicting viewpoints

"Add the budget numbers that were discussed"
→ Pulls specific figures from the transcript

"Rewrite the action items with more detail"
→ Expands terse action items with transcript context

Step 6 — Measure and Track Quality

MetricTargetHow to Measure
Transcription accuracy>95% word accuracySpot-check 2-3 min of transcript vs. audio
Action item detection>90% capturedCompare enhanced notes to manual list
Decision accuracy100% correctVerify all listed decisions actually happened
Processing time<2 min for 30-min meetingTimestamp when meeting ends vs. when notes are ready
Enhancement usefulness4+/5 team ratingMonthly survey: "How useful are Granola notes?"

Track these monthly. If accuracy drops below target:

  1. Check audio setup (most common cause)
  2. Review template structure
  3. Verify meeting practices are being followed
  4. Contact Granola support for persistent issues

Output

  • Audio setup optimized for maximum transcription accuracy
  • Meeting practices improving AI output quality
  • Templates structured for effective enhancement
  • Quality measurement process established

Error Handling

IssueCauseFix
<85% transcription accuracyPoor microphone or noisy roomUpgrade to wired headset, reduce background noise
Action items missedVague language ("someone should...")Use explicit format: "Action item: @person does X by Y"
Wrong speaker attributionCrosstalk or no name usageState names, avoid overlapping speech
Slow processing (>5 min)Long meeting or server loadNormal for 2+ hour meetings; check status.granola.ai
Hallucinated decisionsAI filling template sectionsReview before sharing; remove decisions that didn't happen
