The world's most popular AI assistant
by OpenAI · Founded 2022
ChatGPT by OpenAI is the most widely used AI assistant in the world, capable of writing, coding, analysis, and reasoning.
ChatGPT is the AI tool that introduced the world to conversational AI, and it remains the most widely used AI assistant with over 200 million weekly active users. Built on OpenAI's GPT-4o model, it can write, code, analyze data, summarize documents, translate languages, solve math problems, and engage in nuanced reasoning across virtually any topic.
The GPT-4o model (now available to free users) represents a significant advancement — it processes text, images, and audio natively, enabling multimodal conversations where you can share a photo and ask questions about it, or upload a document and have it analyzed.
ChatGPT Plus ($20/month) unlocks the full GPT-4o experience with higher rate limits, access to the DALL-E 3 image generator, Advanced Data Analysis (upload spreadsheets and get AI-generated insights and charts), and the ability to create custom GPTs — personalized AI assistants trained on your specific instructions and data.
The GPT Store allows Plus users to access thousands of community-built custom GPTs for specific use cases — from legal document review to recipe generation to coding assistance — extending ChatGPT's capabilities far beyond its default behavior.

ChatGPT Plus is the one tool I'd keep if I could only keep one. I use it for research, first drafts, editing, brainstorming, and coding help. The Advanced Data Analysis feature alone has saved me dozens of hours analyzing client survey data. Indispensable.
I use ChatGPT for debugging, code review, architecture discussions, and learning new frameworks. GPT-4o's reasoning is genuinely impressive — it catches subtle bugs that I've been staring at for hours. The free plan is surprisingly capable for basic coding tasks.
ChatGPT is my first stop for almost everything. The capabilities are remarkable. My only caution is that it occasionally states incorrect facts with complete confidence. Always verify important claims, especially for recent events or specific statistics.
Yes, ChatGPT has a free plan with access to GPT-4o (rate limited). ChatGPT Plus at $20/month provides full GPT-4o access, DALL-E 3, Advanced Data Analysis, and higher rate limits.
GPT-4o ("o" for omni) is OpenAI's most advanced model. It processes text, images, and audio natively in a single model, is faster than GPT-4, and is available to free users (with limits). GPT-4o is the recommended model for most use cases.
By default, OpenAI saves your conversations and may use them to improve their models. You can disable this in Settings > Data Controls > Improve the model for everyone. ChatGPT Team and Enterprise plans have stronger data privacy protections.
