a memory your agents can work from.
the solstone app takes in what you share with it, from your screen and your audio to the places you go and your terminal. all of it goes into your journal, on a computer you own, and the agents you choose work from it.
free and open source. your journal lives on an Apple silicon mac, a windows PC or a linux computer, and phones pair with it.
- asked
- What did Paris Duke ask for, and how did the versioning rule change during the week?
- answered
- Paris Duke from Ducal Freight asked for three things, and the versioning rule went from "both sides must approve every change" to "silence for 48 hours counts as approval."
the answer came from Claude Code, reading the demo journal on the same computer. this is the opening of its answer, as it came back.
how your agents read it →how it works
what you get
the people and projects in your days
remembered across days, with the moments that connect them.
your meetings, transcribed
on your computer by default. once you confirm your voice, your journal names your own lines from then on.
a briefing each morning
your day ahead, written from your own material.
search across all of it
from the command line, or from your agents.
what your agents get
the agents you already use can work from your journal. you choose which ones.
on the same computer
a local connection for any agent that speaks MCP. on linux, your journal also adds a solstone skill for Claude Code, Codex and Gemini CLI.
on your wifi or VPN
pair an agent with a code from your journal's agents app.
from anywhere
through a tunnel of your own, or through solstone.me.
yours, by structure
your journal keeps the originals in open formats, in a folder on your own disk. you can back it up, hand it down, and take it anywhere.
sol pbc can't sell or license your data, even anonymized or aggregated, and can't use it for targeted advertising or behavioral profiling. that's written into our articles of incorporation, and it can't be amended without the personal signature of our founder, jer miller. after him, the language can only get stronger, never weaker.
there's no telemetry, no analytics vendor, and no behavioral tracking. on its own, solstone only reaches out to fetch its updates, models and tools, which leaves the same kind of logs as visiting any website. the privacy policy
open source
solstone is open source and free, all of it: the solstone app on every platform, your journal, and the connection between them, under the AGPL. solstone itself never asks you to sign in.
you don't have to take our word for any of it. read the code and build it yourself. trust.solstone.app walks through the signed records we publish, including the journal's releases on mac, windows and linux, and links back to the originals.
optional services
sol pbc runs a few services, if you want them. each one has a free way to do it yourself that we fully support, there's no lock-in, and you never have to pay us.
private network $20/yr
reach your journal from your phone, from anywhere.
or your own: your wifi, or your own VPN.
encrypted backup $48/yr
a copy of your journal, encrypted before it leaves, that only you can read.
or your own: any storage bucket you choose.
solstone.me $5/yr
an address for your journal, so an agent you already use can reach it.
or your own: a tunnel that only passes the bytes through.
confidential processing $96/yr
thinking off your device, on confidential hardware sol pbc runs, with no content retained.
or your own: a model on your computer, the default, or your own model.
early days. on a mac, on windows and on your phone, solstone installs like any app. on linux, setup takes a step in the terminal. expect a few rough edges, and tell us when you find one.
