Choose Perplexity for cited research and ChatGPT for a general work assistant; ChatGPT Business lists below Enterprise Pro. Perplexity builds every answer around inline citations and offers models from several providers, while ChatGPT runs on OpenAI's models and adds ChatGPT Work and Codex on the same plan. Each sells business seats with web search, file analysis, connectors, admin controls, and an agent for multi-step work.

Choose Glean for questions about the company and Perplexity for questions about the outside world. Perplexity answers from the public web first and adds the files each user connects or adds to a Project. Glean indexes company apps through 275+ connectors with each source's permissions enforced, and adds web search as an admin-configured tool.
