What is ChatGPT? Complete Beginner Guide 2026

TamilTech AI summary

ChatGPT is an AI chatbot from OpenAI that launched in November 2022 and now helps over 100 million people chat naturally, answer questions, write content, code, and learn new topics. It works like a super-smart assistant trained on huge amounts of text, so it gives direct conversational replies and remembers context better than a regular Google search, though it can still make mistakes or miss very recent events. You can sign up free at chat.openai.com or pay $20 a month for ChatGPT Plus to get faster access, stronger models like GPT-4o, and extras such as image generation. It is generally safe for everyday use if you avoid sharing passwords or sensitive data, double-check important facts, and skip it for medical or legal emergencies. Overall it is a simple way for students, professionals, and curious beginners to try powerful AI, with alternatives like Google Gemini, Claude, and Microsoft Copilot also worth exploring.
