Frequently Asked Questions
Q1What is the best free YouTube transcript generator?
NoteLM.ai offers the best free YouTube transcript generator with unlimited usage, no account required, timestamps included, and multiple export formats (TXT, SRT, JSON). It's faster than most alternatives at 2-3 seconds per transcript.
Q2Are YouTube transcript generators accurate?
Accuracy depends on the source captions. When extracting YouTube's auto-captions, expect 85-95% accuracy. Manual captions provide 99%+ accuracy. The transcript generator itself doesn't affect accuracy—it extracts existing caption data.
Q3Do I need to pay for YouTube transcripts?
No. YouTube's built-in transcript feature is completely free. Third-party tools like NoteLM.ai also offer free unlimited transcripts. Paid tools like Rev.com or Otter.ai offer additional features but aren't necessary for basic transcript extraction.
Q4Can these tools transcribe videos without captions?
Most YouTube transcript generators extract existing captions. For videos without captions, you need AI transcription tools like Otter.ai or Rev.com that process the audio directly. This typically requires a paid account.
Q5Which format should I download transcripts in?
Choose TXT for reading and note-taking, SRT for video editing or creating subtitles, and JSON for developers who need structured data. Most users prefer TXT format for its simplicity.
Q6How do I get timestamps with my transcript?
Use an external tool like NoteLM.ai. YouTube's built-in transcript removes timestamps when you copy the text. Online generators preserve timestamps in all export formats.
Q7Can I edit the transcript after downloading?
Downloaded TXT and SRT files can be edited in any text editor. Some tools like Otter.ai and Sonix include built-in editors. NoteLM.ai provides clean output that's easy to edit in your preferred application.
Q8Are these tools safe to use?
Reputable transcript generators like those listed here are safe. NoteLM.ai doesn't store your data, and YouTube's built-in feature is entirely on-platform. Avoid tools that require suspicious permissions or excessive personal information.
Conclusion
For most users, NoteLM.ai provides the best free YouTube transcript generator experience with its unlimited usage, instant results, and no-signup-required approach. YouTube's built-in feature works well for quick viewing, while specialized tools like Otter.ai and Tactiq suit users with specific needs like live transcription or meeting notes.
Start with NoteLM.ai for your transcript needs—it's free, fast, and requires no commitment. If you find you need advanced features like editing or live transcription, explore the paid options we've reviewed.
