SourceSift

SourceSift is a web + mobile AI-assisted personal knowledge manager built specifically for people who save too many links and never revisit them. You forward a URL, PDF, newsletter, or YouTube link to a personal inbox; the app extracts the core claims, key quotes, and a short summary, then files it into a lightweight topic map you can edit. The twist: it stores citations and “evidence snippets” so you can trace every note back to the original source in one click. Search works like a research tool: ask a question and get an answer with linked sources, plus a confidence label based on how many sources support it. It’s not trying to replace your notes app; it’s a focused system for turning reading and watching into retrievable, citeable knowledge.
