Frequently Asked Questions
Everything you need to know about SubKun.
How do I get a transcript of a YouTube video?
Install the SubKun Chrome extension and open any YouTube video — the full transcript appears beside it automatically, cleanly segmented into readable sentences. No setup, no copy-paste.
Can SubKun summarize a YouTube video?
Yes. SubKun gives you a plain-language summary up front, so you know what a video covers before you commit — and you can click any point to jump to that moment. Summaries are part of Pro.
Can I ask questions about a video?
Yes — Ask AI answers questions about that specific video. And when you don't know what to ask, it hands you the exact questions a sharp student would, so you just click to go deeper. Unlimited on Pro.
Is SubKun free?
Yes! The basics — the readable transcript and clean AI segmentation — are completely free. Pro adds summaries, unlimited Ask-AI, full transcription for videos without captions, and downloads.
Does it work for videos without captions?
Yes. SubKun cleans up and re-segments YouTube's auto-captions into readable text. If a video has no captions at all, SubKun Pro transcribes the audio from scratch using state-of-the-art ASR technology.
Is my personal data safe?
We take privacy very seriously. SubKun only processes the audio/transcript of the videos you watch, in order to provide the service. We never sell your personal data or browsing history to any third party.
