Choose Glean if

Choose Perplexity if
Researchers, analysts and anyone who wants answers with sources rather than a chat.
- Fast, sourced answers beat ten blue links
- Model choice and Deep Research on Pro
- Clean, focused product
Look elsewhere if: Long creative writing or agentic coding (Claude, ChatGPT).
