Content Summarizer

A tool to summarize YouTube videos using AI

Content-Summarizer is a simple CLI program that summarize Youtube videos using Google Gemini.

⬇️ Installation

Prerequisites

You need to have Python 3.11+ and FFmpeg installed on your system.

Recommended Installation

The best way to install is using uv to keep the environment isolated:

uv tool install content-summarizer

Or if you prefer to use pipx:

pipx install content-summarizer

You can also use the standard pip, but be aware that it will install the package in your global or current environment:

pip install content-summarizer

Usage

The application has two main commands: summarize and config.

• summarize: Fetches and summarizes a given YouTube URL. This is the main command.
• config: Sets default values for flags, so you don't have to type them on every run. These settings are saved in a system-specific user configuration directory.

For a full list of all commands and flags, run content-summarizer --help.

The summarize Command

Basic Usage

content-summarizer summarize "YOUR_YOUTUBE_URL_HERE"

Common Summarize Flags

# Change the audio speed factor for faster transcriptions
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -s 2.5

# Change Whisper (Faster-Whisper) Model
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -w large-v2

# Change Gemini Model
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -g 2.5-pro

# Decrease console verbosity (shows only warnings and errors)
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -q

# Make the console output completely silent (summary output still works)
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -qq

# Disable the summary output in the terminal
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" --no-terminal

# Specify an output path for the creation of an output summary file alongside the normal terminal output
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -o "YOUR_OUTPUT_PATH_HERE"

# Keep the cache directory after execution for re-runs
content-summarizer summarize "YOUR_YOUTUBE_URL_HERE" -c

The config Command

Common Config Flags

# Specify default output path
content-summarizer config -o "YOUR_OUTPUT_PATH_HERE"

# Specify default speed factor
content-summarizer config -s 1.5

# Specify default API KEY
content-summarizer config --api-key "YOUR_OWN_WHISPER_API_KEY_HERE"

# Specify default Google AI Studio API KEY
content-summarizer config --gemini-key "YOUR_GOOGLE_AI_KEY_HERE"

🛠️ Configuration

The application resolves settings with the following priority order:

1. Command-line Flags: Always takes top priority for the current run.

2. Environment Variables: Loaded from an .env file or system environments.

3. User Configuration: Defaults set via the config command.

4. Application Defaults: The program's default values. You can see them right here.

📡 Using the Remote Transcription API

The --api flag allows you to offload transcription to a remote server. This project includes a simple Flask API in the flask_api/ directory that you can deploy yourself.

To set up the API, you will need to install its specific dependencies:

# Navigate to the api directory
cd flask_api/

# Install the API dependencies
uv pip install -r requirements.txt

To use this feature, you must:

1. Deploy the application found in the flask_api/ folder to a server of your choice.
2. Use the --api-url and --api-key flags (or set them as defaults using the config command) to point the CLI to your deployed API.

Fell free to use your own API key, you just need to put it in the API .env. I recommend the use of the following script to generate a safe API key, just copy and paste in any terminal:

python -c "import secrets, string; print(''.join(secrets.choice(string.ascii_letters + string.digits) for _ in range(30)))"

A detailed deployment guide is beyond the scope of this README.
