v3.1: WebLLM summarization, improved translations, copy button, removed mini player
Some checks failed
Docker Build & Push / build (push) Has been cancelled

- Added WebLLM service for client-side AI summarization and translation
- Improved summary quality (5 sentences, 600 char limit)
- Added Vietnamese character detection for proper language labels
- Added Copy button for summary content
- Key Points now extract conceptual ideas, not transcript excerpts
- Removed mini player (scroll-to-minimize) feature
- Fixed main.js null container error
- Silent WebLLM loading (no overlay/toasts)
- Added transcript service with yt-dlp

# KV-Tube
**A Distraction-Free, Privacy-Focused YouTube Client**
# KV-Tube v3.0
> [!NOTE]
> Designed for a premium, cinematic viewing experience.
> A lightweight, privacy-focused YouTube frontend web application with AI-powered features.
KV-Tube removes the clutter and noise of modern YouTube, focusing purely on the content you love. It strictly enforces a horizontal-first video policy, aggressively filtering out Shorts and vertical "TikTok-style" content to keep your feed clean and high-quality.
KV-Tube removes distractions, tracking, and ads from the YouTube watching experience. It provides a clean interface to search, watch, and discover related content without needing a Google account.
### 🚀 **Key Features (v2.0)**
## 🚀 Key Features (v3)
* **🚫 Ads-Free & Privacy-First**: Watch without interruptions. No Google account required. All watch history is stored locally on your device (or self-hosted DB).
* **📺 Horizontal-First Experience**: Say goodbye to "Shorts". The feed only displays horizontal, cinematic content.
* **🔍 Specialized Feeds**:
* **Tech & AI**: Clean feed for gadget reviews and deep dives.
* **Trending**: See what's popular across major categories (Music, Gaming, News).
* **Suggested for You**: Personalized recommendations based on your local watch history.
* **🧠 Local AI Integration**:
* **Auto-Captions**: Automatically enables English subtitles.
* **AI Summary**: (Optional) Generate quick text summaries of videos locally.
* **⚡ High Performance**: Optimized for speed with smart caching and rate-limit handling.
* **📱 PWA Ready**: Install on your phone or tablet with a responsive, app-like interface.
- **Privacy First**: No tracking, no ads.
- **Clean Interface**: Distraction-free watching experience.
- **Efficient Streaming**: Direct video stream extraction using `yt-dlp`.
- **AI Summary (Experimental)**: Generate concise summaries of videos (Currently disabled due to upstream rate limits).
- **Multi-Language**: Support for English and Vietnamese (UI & Content).
- **Auto-Update**: Includes `update_deps.py` to easily keep core fetching tools up-to-date.

You can run KV-Tube easily using Docker (recommended for NAS/Servers) or directly with Python.
## 🔧 Installation & Usage
### Option A: Docker Compose (Recommended)
Ideal for Synology NAS, Unraid, or casual servers.
### Prerequisites
- Python 3.10+
- Git
- Valid `cookies.txt` (Optional, for bypassing age-restrictions or rate limits)
1. Create a folder `kv-tube` and add the `docker-compose.yml` file.
2. Run the container:
```bash
docker-compose up -d
```
3. Access the app at: **http://localhost:5011**
### Local Setup
1. Clone the repository:
```bash
git clone https://git.khoavo.myds.me/vndangkhoa/kv-tube.git
cd kv-tube
```
2. Install dependencies:
```bash
pip install -r requirements.txt
```
3. Run the application:
```bash
python wsgi.py
```
4. Access at `http://localhost:5002`
**docker-compose.yml**:
```yaml
version: '3.8'
### Docker Deployment (Linux/AMD64)
services:
kv-tube:
image: vndangkhoa/kv-tube:latest
container_name: kv-tube
restart: unless-stopped
ports:
- "5011:5000"
volumes:
- ./data:/app/data
environment:

```bash
docker pull vndangkhoa/kv-tube:latest
docker run -d -p 5002:5002 -v $(pwd)/cookies.txt:/app/cookies.txt vndangkhoa/kv-tube:latest
```
### Option B: Local Development (Python)
For developers or running locally on a PC.
## 📦 Updates

The HTTP protocol is the foundation of data communication for the World Wide Web.
Hypertext documents include hyperlinks to other resources that the user can easily access, for example, by a mouse click or by tapping the screen in a web browser.
HTTP is an application layer protocol for distributed, collaborative, hypermedia information systems.
Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989.
Standards development of HTTP was coordinated by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), culminating in the publication of a series of Requests for Comments (RFCs).
The first definition of HTTP/1.1, the version of HTTP in common use, occurred in RFC 2068 in 1997, although this was deprecated by RFC 2616 in 1999 and then again by the RFC 7230 family of RFCs in 2014.
A later version, the successor HTTP/2, was standardized in 2015, and is now supported by major web servers and browsers over TLS using an ALPN extension.
HTTP/3 is the proposed successor to HTTP/2, which is already in use on the web, using QUIC instead of TCP for the underlying transport protocol.
