How do you manage context/memory across multiple AI tools?

I'm curious how others are handling this: I use Claude for some tasks, Cursor for coding, ChatGPT for research, and Perplexity for quick lookups.

The problem is none of them know what I've discussed with the others.

I find myself re-explaining the same context repeatedly, or copy-pasting from Notion docs.

For those of you heavily using AI tools:

- How are you managing shared context across tools?

- What's your current workflow for keeping AI "memory" consistent?

- Have you found any solutions that work well?

Especially interested in hearing from teams where multiple people need to access the same knowledge base across different AI sessions.
