a memory your agents can work from.

on your machine, owned by you.

solstone is an open source, local-first journal of what you see and hear. it runs on your own machine and turns your day into context the agents you already use can work from, so they stop starting blind. always private, only yours.

every agent you run inherits nothing. every session starts cold. solstone is the memory they can finally read: your projects, the people, what you decided last time. none of it leaves your control.

two parts, all yours: your observers and your journal, where sol lives and tends your memories.

open source and yours. all processing on your machine. sol pbc can never sell your data, and any future acquisition is conditional on the successor being legally bound to preserve the same protections. these aren't promises; they're irrevocable covenants in the articles of incorporation.

early days. solstone is open source and hands-on, so expect time in the terminal and a few rough edges as we build.
