ViralMint is an AI YouTube chapter generator that uses local Whisper transcription to automatically create video timestamps and logical segment headers for your description.
Most 'auto-chapter' tools just split a video every 5 minutes. ViralMint reads the actual Whisper transcript and identifies semantic shifts in the conversation, placing chapters where the topic actually changes. This results in chapters like 'The Setup' and 'Final Comparison' instead of 'Part 1' and 'Part 2'.
By using local faster-whisper, ViralMint identifies the exact millisecond a speaker changes topics. This precision ensures that when a viewer clicks a chapter in your YouTube description, they land at the beginning of the sentence, not in the middle of a breath.
Processing happens entirely on your machine. No need to upload your unreleased video to a cloud service. Generate your chapters, copy the text into your YouTube upload, and you're done. No per-minute cloud billing.
Drag your finished mp4 into the Downloaded Videos or Tools section. ViralMint works with any source file, even those not yet published.
Select the Auto Chapters tool. Whisper will begin transcribing your audio locally to find the word-level timestamps needed for accurate segmenting.
The AI will suggest 5-15 chapters depending on video length. You can tweak the titles or adjust a timestamp if you want a segment to start slightly earlier.
Click 'Copy to Clipboard'. The output is formatted in the standard '00:00 - Title' format that YouTube recognizes to automatically generate the video scrubber segments.
