ChatGPT is OpenAI's flagship conversational AI assistant, used by hundreds of millions of people for writing, coding, research, analysis, and image creation. It works through a chat interface on web, desktop, and mobile: you ask in plain language, and it can also browse the web, analyze uploaded documents and spreadsheets, generate images, hold natural voice conversations, and carry out multi-step tasks on its own.
Among its capabilities, Deep Research runs extended investigations across many sources and returns structured, cited reports; memory carries your preferences and context across conversations; Projects organizes related work; and Custom GPTs let anyone build a tailored assistant without writing code. The Codex agent writes, explains, and debugs code, while voice mode supports low-latency back-and-forth spoken interaction. Integrations with tools like Canva and PowerPoint extend ChatGPT into everyday creative and office workflows.
ChatGPT suits individuals, students, and professionals who want a general-purpose assistant for drafting, brainstorming, learning, and light automation, while Business and Enterprise tiers add shared workspaces, admin controls, and stronger data protections for teams. It runs on OpenAI's current model family, with paid tiers unlocking stronger reasoning models, higher usage limits, priority access at peak times, and an ad-free experience; a free tier with usage caps is available.
Plan lineups change often, so it is worth checking the official pricing page before subscribing: recent 2026 reviews describe a free tier, a budget Go tier, Plus at $20 per month, higher-usage Pro tiers, and per-seat business plans. For anyone exploring AI assistants, ChatGPT remains the default starting point: approachable, broadly capable, and closely tied to OpenAI's newest model releases.
