solstone

observes what you see and hear and gives you an AI co-brain — searchable memory, meeting prep, a knowledge graph of every person in your life. nothing to connect, no services to authorize. it just experiences your digital world alongside you.

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 — expect time in the terminal and a few rough edges as we build.
