How to Generate Subtitles in 3 Steps
No timeline editor, no typing to the beat of the audio — the subtitle generator handles the timing for you.
Upload your video or audio
Drop in MP4, MOV, WebM, MP3, WAV, and more — up to 30 minutes and 100MB on the free plan, 210 minutes and 500MB on paid plans. A captioned YouTube link works in the same box.
Let the AI transcribe it
The AI subtitle generator transcribes the audio into clean, timestamped segments — punctuation and casing included, each line anchored to its exact moment.
Download SRT or VTT
Export as SRT for YouTube and most editors, VTT for web players, or TXT with timestamps for review. Need a tweak? Every subtitle format opens in any editor.
What You Get from Every File
One upload, every deliverable a subtitle workflow needs.
SRT subtitles
The universal format — accepted by YouTube, editing suites, and practically every video platform. Numbered cues with millisecond timing, downloadable with or without timestamps depending on where they're headed.
VTT subtitles
The web-native WebVTT format for HTML5 players, LMS platforms, and modern streaming embeds.
Timestamped transcript
The full transcript with clickable timestamps — verify any line against the recording before you publish it under your video.
Translation built in
Translate the transcript into major languages inside the result page — the starting point for multilingual subtitle tracks.
Clean text export
TXT with or without timestamps, for show notes, blog posts, or a script archive — from the same file.
Who Uses an AI Subtitle Generator?
Anyone who publishes video — because most viewers will meet it with the sound off.
YouTube & course creators
Upload accurate SRT files instead of trusting auto-captions with your terminology. Cleaner captions read better, index better, and stop your product names turning into nonsense on screen.
Short-form & social video
Sound-off scrolling is the default. Generate subtitles for every cut and keep the message intact on mute — the same SRT drops into CapCut, Premiere, or your editor of choice.
Accessibility compliance
Subtitles make content usable for deaf and hard-of-hearing audiences — and for classrooms, libraries, and offices where audio isn't an option. For many organizations, captions are a compliance requirement, not a nice-to-have.
Training & internal video
Caption onboarding and training recordings so they're searchable, skimmable, and watchable anywhere — and keep the transcript on file as the text version of the same material.
TurboCast vs Other Subtitle Generators
Where this subtitle generator is genuinely different — and where it honestly isn't.
| Feature | Typical subtitle tool | TurboCast |
|---|---|---|
| Export formats | Often SRT only | SRT + VTT + TXT |
| Timestamped transcript to verify against | Rarely | Always, with clickable timestamps |
| Translation of the transcript | Paid add-on | Built into the result page |
| Summary, flashcards & podcast from the same file | One click | |
| Built-in subtitle timeline editor | Sometimes | Not yet — export and refine in any editor |
| Burned-in (hardcoded) captions | Sometimes | Not offered — subtitle files only |
| Free tier | Varies | 3 generations a day, files up to 30 min / 100MB |
Subtitles Are One Output of Many
The transcription behind your subtitles is reusable material. The same upload gives you an AI summary with chapters and takeaways, turns into flashcards or a quiz if the video is study material, or becomes a narrated podcast episode. Caption the video today, repurpose it tomorrow — without processing the file twice.
AI summary
TL;DR, chapters, and highlights from the same transcription.
Flashcards & quiz
Turn lecture videos into study material in one click.
AI podcast
A narrated audio version for listening on the move.
Why Subtitles Matter
Most video is watched without sound — on feeds, in offices, on commutes. A video without subtitles simply loses those viewers at the first silent second.
Subtitles also do double duty: they make content accessible to deaf and hard-of-hearing audiences, and they give platforms and search engines text to index.
The old cost was the typing: captioning by hand runs several minutes of work per minute of video. An AI subtitle generator collapses that to an upload and a download.
What Is an AI Subtitle Generator?
An AI subtitle generator is a tool that transcribes a video or audio file and outputs subtitle files — timed text cues in formats like SRT and VTT that players render over the video.
TurboCast transcribes your file into timestamped segments, then formats them as numbered SRT cues or WebVTT blocks. The full transcript stays attached to the result, so you can check any line against the recording before publishing.
SRT is the universal interchange format; VTT is its web-native sibling for HTML5 players. TurboCast exports both from the same job — no re-processing, no second upload.
