Our take
Pick ChatGPT if everyone who wants a hosted general assistant — writing, Q&A, light research, images. Pick Perplexity Comet if people who already use Perplexity Search and want the same assistant inside the browser. Skip ChatGPT if teams that cannot send prompts to OpenAI, or developers who need a repo-aware IDE (Cursor) or a local runtime (Ollama). Skip Perplexity Comet if teams that cannot leave Chrome, or users
