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

How are credits calculated for this conversion?
Cost: 1 credit per minute
How it works:
- Files up to 1 minutes: 1 credit (minimum)
- 2 minutes: 2 credits
- 3 minutes: 3 credits
- 4 minutes: 4 credits
Example: A 10-minute file = 10 credits. A 180-minute (3h) audiobook = 180 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 |
|---|---|---|
| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
| Business | — | 25,000 credits/month |
Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.
Note: With 1 credit per minute, audio files under 1 MB cost 1 credit each. Pro users can convert 10,000 audio files per month.
