Make subtitles for a video without uploading it
Online subtitle tools need your video on their server. KinoFlux Whisper Studio finds the words on your own computer and gives you an SRT file or a video with captions.

You have a video and you need subtitles. Most results on Google are websites: upload the video, wait, then download captions. Many limit the length or add a watermark unless you pay.
The problem with online subtitle tools#
- The whole video goes to their server.
- Long videos take a long time to upload.
- Free plans are short or watermarked.
- Some videos are private: family, clients, lectures, meetings.
Do it on your computer#
KinoFlux Whisper Studio runs speech-to-text with Whisper models on your own machine.
- Open the video or audio file (MP4, MKV, MOV, WebM, WAV, MP3, M4A and more).
- Pick a model. Tiny is fast for a first draft; larger models are more accurate but slower.
- Let it find the words, then fix any lines in the editor.
- Export an SRT file, a TXT transcript, or an MP4 with the captions burned in.
Your project saves itself as you work.
