​
What works here

  • Memory recall and save. Injected memories ride along with your question, so Perplexity keeps your context while it searches the web. New memories are saved back as you go.
  • Extract memory pill. Select text in a chat and click Extract memory to save that snippet.

​
Limitations

  • No chat history sync here. The extension captures new conversations only on ChatGPT, Claude, Gemini, Grok, DeepSeek, and TypingMind. You can still recall chat history imported from those tools while researching in Perplexity.
