ChatGPT
The world's most used AI assistant
Overview
ChatGPT is developed by OpenAI and remains the world's most widely used AI assistant in 2026. What started as a text chatbot has evolved into a comprehensive multimodal platform handling text, images, voice, files, and video.
For business owners, ChatGPT's greatest strength is its breadth — it covers almost every use case, from drafting marketing copy and analysing spreadsheets to writing code and generating visuals. Its memory feature learns your preferences and brand voice over time.
The GPT-4o and o3 reasoning models represent a significant leap in accuracy, particularly for logic-heavy tasks.
ChatGPT is the safest first choice for any business new to AI. Its combination of writing quality, image generation, voice mode and sheer versatility makes it the most complete AI assistant available. The free tier alone will transform how you work.
