Subtitle Generator for YouTube Video
Generate subtitle files for YouTube videos before you publish. SubSmith creates editable SRT subtitles from local video files, so you can clean them up before upload.
What It Does
This route targets people who want subtitles for a YouTube workflow but still need control over the underlying file. Instead of relying on auto-captions after upload, generate and review the subtitle file first.
- Generate subtitles before publishing to YouTube
- Edit the subtitle text before export
- Export SRT for upload in YouTube Studio
- Useful for tutorials, lectures, and long-form content
How It Works
- Open the source video file in SubSmith
- Generate subtitles with Whisper AI
- Correct names, terminology, and timestamps
- Export SRT and upload it with the final video
See the Workflow
These are the parts of the app that matter most for subtitle generation: importing media, reviewing subtitles, looking up words, and saving useful lines for later study.


Best For
- Creators who want cleaner captions than default auto-captions
- Educational and tutorial channels
- Anyone publishing local video files to YouTube
Why SubSmith
YouTube auto-captions are fine for rough accessibility, but they are not ideal when you care about terminology, names, or foreign-language content. SubSmith gives you a review step before the video goes live. After subtitles are finalized, tools like YouTube description generators can help streamline the rest of your publishing workflow.
Built for Learning, Not Just Export
Most subtitle tools stop at transcription and export. SubSmith also supports popup dictionary lookup while you read through subtitles and lets you turn useful lines into flashcards for later review.
- Popup dictionary support for quick word lookups while reviewing subtitles
- Flashcard creation from subtitle lines for Anki-based study workflows
- Useful if you want subtitles and a language-learning workflow in the same app
