Practical details
What this MVP does and does not do
Private by default
In this static version, subtitle text is processed in your browser. There is no upload or login flow.
Creator formats
Use it for standard SRT and simple WebVTT files from YouTube, editors, course platforms, and caption tools.
Translation guardrails
The prompt keeps numbering, timestamps, and line breaks visible so AI translation is less likely to break structure.
Manual review still matters
Names, brand terms, reading speed, and cultural phrasing should be checked before publishing localized subtitles.
FAQ
Subtitle localization basics
Can I convert SRT to VTT in the browser?
Yes. This page converts timestamps and adds the WebVTT header without sending subtitle text to a server.
Why do AI subtitle translations break timestamps?
Many prompts send plain text only. Keep caption numbers, timestamps, and line breaks in the prompt so the model returns the same structure.
What should I publish after the tool page?
Publish pages for format comparisons, common subtitle errors, language-specific translation workflows, and platform-specific subtitle guides.
Does this page upload subtitle files?
No. The current MVP processes pasted subtitle text in the browser. Add a formal privacy policy before adding accounts, uploads, or paid translation.
