Frequently Asked Questions
Why choose Word over PDF?
Word documents are fully editable — correct transcription errors, reformat text, add headings, insert comments, and collaborate with Track Changes.
PDF is fixed; Word is for when you need to work with the content before finalizing.
Can I edit the transcription in Word?
Yes, completely. The .docx file opens in Microsoft Word, Google Docs, or LibreOffice.
Correct errors, reformat paragraphs, add speaker labels, insert timestamps, or highlight key sections.
Use Track Changes for collaborative review workflows.
Can I convert Word to PDF later?
Yes. Once you've finished editing, export to PDF from Word (File → Save As → PDF) or Google Docs (File → Download → PDF).
This gives you the best of both worlds: editable draft, then polished final document.
When should I use Word vs PDF vs Markdown?
Choose the format that fits your workflow:
- Word — When you need to edit, collaborate, or use Track Changes
- PDF — When you need a polished, uneditable document to share or archive
- Markdown — When importing into Obsidian, Notion, or other notes apps

How does the AI title formatting work?
Our AI analyzes your filename and generates a professional, human-readable document title.
For example, 'meeting_2024_01_15_final_v2.mp3' becomes 'Meeting - January 15, 2024'.
This title appears at the top of your Word document.

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.
