# ChatGPT > AI chatbot built on the GPT large language models that enables natural conversations and assists with a wide range of tasks. ChatGPT is an AI-powered conversational assistant developed by OpenAI that leverages advanced large language models from the GPT family. The system is designed to understand and generate human-like text based on the conversations and prompts it receives, making it capable of assisting with a wide range of tasks from answering questions and drafting content to solving problems and generating creative ideas. ChatGPT's interface is structured as a chat dialogue, allowing for natural back-and-forth conversations that maintain context over multiple exchanges. What distinguishes ChatGPT is its versatility and ability to understand context and nuance in natural language. The system can perform tasks across diverse domains, from explaining complex concepts in simple terms to writing code, creating content in specific styles, or helping brainstorm ideas. ChatGPT is built on increasingly sophisticated models (initially GPT-3.5, later GPT-4) that improve its reasoning abilities, factual accuracy, and comprehension of user intent. OpenAI has implemented various safety measures and content moderation systems to reduce harmful or misleading outputs, though these remain ongoing challenges. Over time, ChatGPT has evolved to include additional capabilities beyond text responses, including web browsing for access to current information, data analysis, image understanding, and document processing capabilities. The system operates in multiple tiers, with a free version offering basic functionality and subscription options providing access to more advanced models, enhanced features, and higher usage limits. As one of the most widely adopted consumer AI products, ChatGPT has become a prominent example of how large language models can be applied to everyday tasks and professional workflows across numerous fields. ## Features - Natural language conversation - Multi-turn dialogue with context retention - Web browsing capability - Code generation and explanation - Document analysis and summarization - Image understanding and generation - Plugin ecosystem for expanded capabilities - Cross-domain knowledge and reasoning ## Integrations Web browser (for browsing mode), DALL-E (for image generation), Microsoft Office (via Copilot), Various plugins (Wolfram Alpha, Zapier, etc.), Custom GPTs, Code interpreters, Third-party applications via API, Browser extensions ## Platforms WEB, IOS, ANDROID ## Pricing Freemium — Free tier available with paid upgrades ## Version GPT-4o ## Links - Website: https://chat.openai.com - Documentation: https://help.openai.com/en/collections/3742473-chatgpt - EveryDev.ai: https://www.everydev.ai/tools/chatgpt
