Export your memory from Perplexity
Perplexity keeps an editable list of what it remembers about you, viewable directly in settings.
1
Open your memory settings
In Perplexity, go to Settings → Personalize → Manage Memories. You'll see each individual memory it has stored, with the option to delete any of them.
2
Copy what's listed
Copy everything shown there as your portable profile.

Perplexity's help center confirms the Memory feature and its Settings → Personalize → Manage Memories location. We couldn't find a way to import memory into Perplexity from elsewhere, so this is an export-only guide for now.
