Overview

Local AI SRT Subtitle Generator is a browser-based tool that creates accurate, synchronized subtitles for videos and audio using OpenAI Whisper models. It processes files entirely on your device, supporting 90+ languages and exporting to SRT, VTT, ASS, or TXT formats. Designed for content creators, educators, podcasters, and YouTubers who need private, secure subtitle generation without uploading their media. This is an independent third-party service and is not operated by the company behind the model it is built around.

How it works

The tool runs OpenAI Whisper models directly in your browser using WebAssembly, so no files are uploaded to servers. You start by selecting media files in mp4, webm, mov, mp3, or wav format, then download the AI model once to your browser. After running the model locally, you can edit the generated subtitles and export them in SRT, VTT, ASS, or TXT formats.

The free Basic plan includes 5 generations per month, access to basic local AI models, and essential editing features. Paid plans unlock unlimited subtitle generation, premium AI models, advanced styling and animation, subtitle burning, translation into 60+ languages, and batch processing. Pricing options include a $6 weekly plan, $12 monthly plan, $69 annual plan, and a $129 lifetime access option.

Who it is for

The tool is built for content creators, YouTubers, educators, podcasters, and video marketers who need subtitles for tutorials, lectures, podcasts, and screen recordings. It is also suitable for developers and businesses that value privacy and want to avoid cloud-based transcription services. The local processing ensures that sensitive content never leaves the user's device.

Key capabilities

Beyond basic subtitle generation, the tool includes an advanced subtitle editor for creating styled and animated subtitles with ASS support.
