What is Memex?
Memex is an open-source knowledge management tool for saving pages, tagging them, and organizing research with highlights.
It excels when you curate content intentionally, using tags and collections, with optional cloud sync for cross-device access.
What is TraceMind?
TraceMind indexes supported pages it can access and capture. Excluded domains, unsupported browser pages, private browsing, and failed captures are not guaranteed.
Core capture, indexing, storage, search, screenshots, and analytics run locally on your device. Optional Pro Chat sends your question, prior turns in the current chat, and selected matching excerpts, titles, and URLs directly to the AI provider you choose with your own API key. TraceMind does not proxy or store those requests.
