Common Questions from Reddit Users
Which free app gives the most minutes per month?
VocalScribe offers a 10-minute free tier to test the service. For regular use, the Pro plan ($12.99/mo, 60 min) works for students with fewer lectures, while Premium ($19.99/mo, unlimited) is best for heavy users. Google Recorder is technically unlimited but only works on Android.
Is Otter.ai still worth it in 2025?
Otter.ai remains popular but has been surpassed by VocalScribe for student use. Otter's 300-minute free tier often runs out mid-semester, forcing upgrades. It's still good for business meetings but not ideal for lecture transcription compared to newer alternatives.
Can I use these apps for Zoom lecture recordings?
Yes! VocalScribe, Otter.ai, and Notion AI all support Zoom recordings. You can either paste the Zoom cloud recording URL or upload the downloaded MP4 file. Real-time transcription during live Zoom lectures works with Otter and Notta.
Which app is best for Android users?
Google Recorder is unbeatable for Android users—completely free, unlimited, and works 100% offline. If you need study tools (flashcards, summaries), use VocalScribe's Android app which offers both transcription and study material generation.
Do any free apps work completely offline?
Google Recorder (Android) and VocalScribe's offline mode work without internet. This is crucial for lecture halls with poor WiFi or when you want privacy. Other apps require internet connection for cloud-based transcription.
What's the most accurate free transcription app?
VocalScribe (90-95%) and Google Recorder (85-90%) offer the highest accuracy among free options. Otter.ai averages 80-85%. For 99% accuracy, you'd need Rev's paid human transcription at $1.50/minute.
