ChatGPT by OpenAI is the most widely adopted general-purpose AI assistant. It handles drafting, editing, coding, document analysis, live web browsing, image generation and voice conversations from a single interface. Because the ecosystem of Custom GPTs and integrations is so deep, most professionals treat it as their default thinking partner — the first tab they open when a task is ambiguous. Free users get access to a strong baseline model with meaningful daily limits; paid tiers unlock the newest reasoning models, higher usage, larger file uploads and priority speed. It is not the best at every specialty, but the breadth, reliability and pace of updates make it the safest starting point for anyone new to AI.
