Frequently Asked Questions
How do I import Markdown into Obsidian?
Just save the .md file to your vault folder. Obsidian auto-indexes new files, so your transcript becomes instantly searchable.
Add YAML frontmatter (tags, date, source) for better organization.
The transcript integrates seamlessly with your existing notes.
Why Markdown instead of plain text?
Markdown works natively with PKM apps (Obsidian, Notion, Logseq, Roam).
It supports headers, links, and formatting that plain text doesn't.
Most importantly, Markdown syncs via any cloud service, renders beautifully in these apps, and future-proofs your notes.
Which apps support Markdown?
Popular apps with native Markdown support:
- Obsidian, Notion, Roam Research, Logseq
- Bear, Craft, Typora, iA Writer
- GitHub, GitLab, and documentation tools
It's the lingua franca of knowledge management.
Can I add tags or frontmatter?
The generated file includes an AI-formatted title as an H1 heading.
For Obsidian workflows, add YAML frontmatter (---) at the top with tags, date, or custom metadata.
The transcript body uses clean paragraphs — ready to link to your other notes.
When should I use Markdown vs Word vs EPUB?
- Markdown — PKM apps, developer tools, GitHub
- Word — Editing, collaboration, Track Changes
- EPUB — E-readers for offline reading

What is the difference between Fast and Quality models?
Two OpenAI Whisper models — choose speed or accuracy:
| Model | Engine | Speed | Cost |
|---|---|---|---|
| Fast | Whisper V3 Large Turbo (809M) | ~216x realtime | 2 credits/min |
| Quality | Whisper V3 Large (1.55B) | ~189x realtime | 5 credits/min |
Fast is the default — great for clear audio, podcasts, and lectures.
Quality uses the full 1.55B-parameter model. Independent benchmarks show ~10% WER for Quality vs ~12% for Fast (Artificial Analysis). Choose Quality for accented speech, noisy recordings, or technical content.
Both models support 99+ languages. Switch in the options panel above.

Can I use Meeting Intelligence with my notes?
Yes — Meeting Intelligence adds speaker labels to your Markdown transcript, making it easy to track who said what in your knowledge base.
When enabled, speaker attribution appears inline with the text:
# Meeting: Q4 Planning
**John:** Let's review the quarterly goals.
**Sarah:** Revenue is up 15% but we need to address churn.This is perfect for Obsidian, Notion, or Logseq workflows where you want to:
- Link speaker names to their profile notes
- Search for everything a specific person said
- Track decisions back to who proposed them
Our AI post-processing attempts to identify speakers by name when they're introduced or addressed in the audio. Important: Name detection isn't perfect — it works best when speakers introduce themselves ("Hi, I'm John...") or are called by name. If names aren't detected, you'll see generic labels like "Speaker 1" and "Speaker 2" which you can easily edit in your notes app.
Meeting Intelligence costs extra credits and is ideal for meeting notes, interviews, and any content where speaker attribution matters in your PKM system.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Guest/Free | 100 MB | 50 files | 3 at once |
| Pro | 1024 MB | 1000 files | 6 at once |

How are credits calculated for this conversion?
Cost: 2 credits per minute
How it works:
- Files up to 1 minutes: 2 credits
- 2 minutes: 4 credits
- 3 minutes: 6 credits
- 4 minutes: 8 credits
Example: A 10-minute file = 20 credits. A 180-minute (3h) audiobook = 360 credits.
Why per-minute? Audio conversion time scales with content duration, not file size. Longer audio requires proportionally more processing.
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Guest | 100 credits/day | — |
| Free | 100 credits/day | — |
| Pro | — | 12,000 credits/month |
Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) reset on your billing cycle date.
Note: With 2 credit per minute, audio files under 1 MB cost 2 credit each. Pro users can convert 6,000 audio files per month.
