ChatGPT

ChatGPT is an AI-powered conversational assistant developed by OpenAI. Launched in November 2022, it quickly became one of the fastest-growing consumer applications in history, reaching 100 million users within two months. The service allows users to interact with large language models through natural conversation, enabling tasks like answering questions, writing assistance, coding help, brainstorming, and creative content generation.

Key Features

Conversational AI: Natural language understanding and generation powered by GPT models
Multi-modal capabilities: Support for text, images, voice, and file uploads (in premium tiers)
Code assistance: Programming help across multiple languages with explanations
Plugins and integrations: Browse the web, analyze data, and connect to third-party services
Custom GPTs: Users can create specialized AI assistants for specific tasks

Technical Infrastructure

The domain is hosted behind Cloudflare infrastructure:
