ChatGPT is an advanced AI-powered chatbot that engages in human-like conversations, answers questions, and assists with a wide variety of tasks. This versatile tool uses natural language processing to help users with writing, coding, analysis, and creative ideation, making it a valuable resource for individuals and businesses across various industries.

Key features:
- Natural Language Conversations: Engages in human-like dialogue on a vast range of topics
- Task Assistance: Helps with writing, coding, research, analysis, and brainstorming
- Multimodal Capabilities: Processes text input/output, understands and analyzes images, and conducts voice conversations (for Plus/Enterprise users)
- Customization: Allows creation of custom versions (GPTs) for specific use cases
- Web Browsing: Accesses and analyzes current information from the internet
- Data Analysis: Analyzes uploaded data files and creates visualizations
- Code Generation & Debugging: Writes and fixes code in various programming languages
- Language Support: Communicates in multiple languages
- Memory & Context Retention: Maintains context within conversations
- Mobile App: Available on iOS and Android devices

How it works:
1. Users access ChatGPT through a web interface or mobile app
2. Users type or speak their queries/prompts to ChatGPT
3. The AI processes the input using its large language model trained on vast amounts of text data
4. ChatGPT generates a relevant response based on its training and understanding of the query
5. Users can have back-and-forth conversations, asking follow-up questions or providing additional context
6. For tasks like coding or data analysis, users can input specific requirements or upload files for ChatGPT to work with
7. Plus and Enterprise users can utilize additional features like image analysis by uploading images

Integrations:
Plugins, API, Zapier, Slack, Microsoft Office
