Human knowledge usually lives in semantic containers, not in flat lists of links or isolated files.
Most software keeps knowledge trapped in separate apps, inboxes, and private silos. Most sharing tools also depend on centralized servers.
Subgrapher is an attempt to build for the open web and open communication instead: a system where references, research, messages, and agents can move across those walls without defaulting to closed platforms.
P2P plus local first for knowledge is such a values driven build. I'm building a consumer app right now in the same neighborhood (organizing the chaos of saved content) and the privacy first instinct is exactly right. Love seeing this framing get more traction with smaller launches like yours.
P2P knowledge sharing is genuinely interesting because the centralized model has so many failure points — the platform changes, goes down, or starts optimizing for things you don't care about. Local-first makes real sense as a counter to that. Curious how you're thinking about discovery though: how do people find relevant knowledge from others on the network without some kind of central index pulling it together?
