Subtitlr (Experimental)

AI-assisted subtitle generation CLI for Youtube

Description

This application, a subtitle generator for YouTube, utilizes OpenAI's Whisper API.

This tool leverages artificial intelligence to efficiently transcribe speech in YouTube videos into text, thereby generating accurate subtitles (in SRT format).

It's designed to improve the accessibility and convenience of video content, ensuring that no matter your language or hearing ability, you can fully engage with and comprehend the material.

Features

Generate subtitles - The simplest way

The simplest way to use Subtitlr without configuration is to use the following command:

Subtitlr generate --id qJpR1NBx4cU --lang fr --output output.srt --apiKey sk-****************************

Generate subtitles - With configuration

You can also use a .env file to store your API key (in OPENAI_API_KEY variable) and use the following command:

Subtitlr configure --apiKey sk-****************************

And after that, you can use the following command without the --apiKey parameter:

Subtitlr generate --id qJpR1NBx4cU --lang fr --output output.srt

Translating subtitles

For translations we offer you the possibility to use the DeepL API with a free account only (500000 per month).

Subtitlr translate --input input.srt --lang EN --output output_EN.srt --apiKeyDeepl ****************************
