About ChatGPT
ChatGPT is OpenAI's conversational assistant: writing, research, coding, image generation and data analysis in one interface, with web browsing, memory, custom GPTs, and API access to the same models. It is the most widely used AI assistant, which matters practically: it is the tool your clients and collaborators already have open, so it sets the baseline everything else is measured against.
It is in daily rotation here. We use it for first-draft copy, quick research passes, throwaway scripts, and summarising long documents. Custom GPTs cover the jobs we repeat with the same instructions every time. Once work moves into a repository it hands off to our coding agents rather than staying in a chat window.
Claude is the alternative we reach for on long-context reasoning and code review. Google Gemini is the easier call if your documents and mail already live in Workspace. Perplexity is better when the job is genuinely search with citations rather than generation. Microsoft Copilot wins on Office integration and enterprise procurement. ChatGPT is the right default when you want one assistant that does most things well and can be handed to a non-technical colleague. It is the wrong call when you need one specialised capability done best — use the tool built for that.
