The world's most popular AI assistant for everything.
ChatGPT is the most widely used AI assistant in the world, built on OpenAI's GPT-4o and o-series reasoning models. It handles writing, coding, analysis, research, image generation, voice conversations, and agentic tasks through a single conversational interface.
ChatGPT by OpenAI is the AI assistant that introduced the world to conversational AI. Powered by GPT-4o for general tasks and o3/o4 reasoning models for complex problem-solving, it covers an extraordinary range of use cases — from drafting emails and writing code to generating images with DALL-E, conducting deep research across 50-100 web sources, and executing multi-step agentic tasks via Codex. The free tier is genuinely powerful, while Plus ($20/mo) and Pro ($200/mo) unlock the frontier models, unlimited image generation, voice mode, and priority access. In 2026, ChatGPT's ecosystem depth — memory, custom GPTs, Actions, and Canvas — makes it the most feature-complete AI assistant available.
Use ChatGPT Deep Research to generate comprehensive, cited reports on any topic. It browses 50-100 sources, reasons over them, and delivers a structured document in 5-15 minutes — replacing hours of manual research.
ChatGPT writes, explains, refactors, and debugs code across all major languages. The code interpreter runs Python in a sandbox, and Codex (Pro) can autonomously build full features in cloud environments.
From blog posts and marketing copy to professional emails and academic essays, ChatGPT generates and refines written content quickly. Canvas enables side-by-side document editing with inline AI suggestions.
Upload a CSV or Excel file and ChatGPT's Advanced Data Analysis mode runs Python to produce charts, statistical summaries, and actionable insights without needing to write a line of code.
Free gives you GPT-4o with usage limits and basic features. Plus ($20/mo) unlocks unlimited GPT-4o, o3 reasoning model, Deep Research, Advanced Voice, Canvas, image generation, and Sora video. Pro ($200/mo) removes all limits and adds o1 Pro, extended thinking, and the Codex cloud coding agent.
It depends on the task. ChatGPT has a broader feature set (voice, video, image gen, custom GPTs, Deep Research all in one). Claude is generally preferred for long-form writing quality, very long document analysis, and nuanced reasoning. Most power users subscribe to both.
Yes — ChatGPT's Memory feature stores facts about you and your preferences across conversations. You can view, edit, or delete memories anytime. Memory is available on Plus and Pro plans. You can also disable it completely if you prefer privacy.
Yes — ChatGPT can search the web in real time using Bing Search integration. Deep Research goes further, autonomously browsing 50-100 sources to produce cited reports. Both features are available on Plus and Pro plans.
