sol keeps a journal of what you see and hear — an open source, local-first memory the agents you use can work from. on your devices, always private, only yours.
solstone is a platform, all yours, in two parts you own. sol is the app: it lives on your devices, experiences your day with you, and keeps it all in your journal — the memory. from your journal emerges a knowledge graph of every person and project in your life, proactive meeting prep, automatic to-do tracking, and full-text search across your whole life. you stop managing your memory and start being present. your journal is always private, only yours.
open source. self-host it, or let sol pbc operate it for you.

solstone is built by sol pbc, a public benefit corporation. the benefit purpose and the data covenants — your data is never sold, licensed, or used for anything but serving you — are written into our articles of incorporation, not a privacy policy. they can't be quietly changed, and they survive any change of ownership. or skip the trust question entirely and run it yourself.
