OpenAI Perplexity
On what the policies say, there's nothing between them. Both are graded D.
OpenAI
ChatGPT trains on your content by default on Free, Plus and Pro, with an opt-out that binds new conversations only. Business and API do not train by default.
Verdict
D
- Trains on you by default
- A self-serve opt-out exists
- On by default. An opt-out exists, but you have to go looking for it.

Perplexity
Perplexity trains on your searches by default on Free, Pro and Max. The switch is real and free — but it is in a help article, not the privacy policy, and it does not reach data already taken.
Verdict
D
- Trains on you by default
- A self-serve opt-out exists
- On by default. An opt-out exists, but you have to go looking for it.
