Is Memex safe?

Clean risk

Curate, annotate, search, and discuss websites, PDFs, and YouTube videos for deep reading.

It also supports summarizing and chatting with websites, PDFs, and YouTube videos, sharing Spaces with others, and syncing to Obsidian, Readwise, and Logseq. The store listing says data is stored on the user’s device and can be backed up through file system sync to a chosen cloud provider.
