Our take
Pick ChatGPT if everyone who wants a hosted general assistant — writing, Q&A, light research, images. Pick OpenAI Deep Research if analysts and students who already pay for ChatGPT Plus or Pro and want a sourced memo. Skip ChatGPT if teams that cannot send prompts to OpenAI, or developers who need a repo-aware IDE (Cursor) or a local runtime (Ollama).
