ChatGPT

ChatGPT is OpenAI's conversational AI assistant that's transformed how people work with information. It can write, analyze, code, research, brainstorm, and explain complex topics in natural conversation. The technology behind ChatGPT is GPT-4, one of the most capable language models ever built. It understands context, follows complex instructions, and generates human-quality text across virtually any domain. Upload images for analysis, PDFs for summarization, or data for insights. For coding, ChatGPT is remarkably capable. It writes functions, debugs errors, explains code, and suggests improvements across most programming languages. Many developers use it as a pair programming partner, talking through problems and iterating on solutions. Writing assistance spans from email drafts to full articles. It adapts tone and style to your needs - professional reports, casual social posts, or technical documentation. The editing capabilities help tighten prose, fix grammar, and improve clarity. ChatGPT Plus ($20/month) adds GPT-4 access, plugins, code interpreter, and DALL-E image generation. The free tier uses GPT-3.5, which is less capable but still useful for many tasks. Enterprise plans add privacy, admin controls, and higher limits.
