It fills itself
Second brains fail because filing is a second job. Here the meetings, the dictation and the agent fill it, so it stays current without discipline.

Free · No account · No cardYour workspace is a folder of plain Markdown files on your Mac: one note per person, company, project, meeting and decision. Your agent writes and links them while you work, and reads them before it answers.
Second brains fail because filing is a second job. Here the meetings, the dictation and the agent fill it, so it stays current without discipline.
The agent reads the relevant notes before answering, so “did we promise SSO?” is answered from the decision you took, not guessed.
Open them in Obsidian, a text editor or Finder. Back them up by putting the folder in iCloud Drive, Google Drive or Dropbox. Change agent tomorrow and the memory comes with you.
Switch the right column from Memory to Documents and the whole vault is there: one folder per kind of thing, the notes your agent wrote, and anything you added yourself. Open a note to read or edit it in place, with its links to everything else.
A folder appears when its first note arrives, never before. Every note has a short header (type, status, who’s involved), which is what lets the agent answer questions instead of only searching text.
What Glowstone shows you is a normal folder on your disk: people/, companies/, projects/, meetings/, decisions/, daily/. Open it in Finder, Obsidian or any text editor and you find the same files with the same names. Nothing lives in a database you can’t open.
Mention that Maya’s export passed QA and the agent updates Atlas.md, Maya’s note and today’s. Every change is shown under the answer, and you can review it line by line and undo it.
Notes mention each other with [[links]]. That’s what lets you ask “what do I know about Marta?” or “what does the data team have open?”, and what the graph on the right draws. It lights up as the agent reads.
Glowstone is an app on your Mac, not a cloud service. Your notes are a folder on your disk and your chats are stored on your Mac. There’s no Glowstone account, and no Glowstone server that receives any of it.
Not your notes, not your chats, not your meetings. Nothing is uploaded to us, so there is nothing for us to read, lose or hand over. On its own the app only checks for updates and downloads the speech model once.
When you ask something, your agent reads the notes it needs to answer: Claude Code sends that to Anthropic, Codex to OpenAI, under your own account and their terms. Choosing the agent is choosing who sees your work, and that’s your call, not ours.
It’s plain Markdown in a folder. Open it in Obsidian, put it in iCloud or Drive, copy it to another Mac. No export step, no lock-in, nothing to cancel: stop using Glowstone tomorrow and every note is still yours, where it was.
Two things only leave your Mac if you set them up: connectors (they belong to your agent) and Telegram (messages go through Telegram). And if you ever send us a problem report, you see everything it contains before it’s sent.
Yes. Glowstone uses plain Markdown and wiki-style links, so you can point it at your vault or have it copied. See the guide on bringing your memory.
No. The workspace is a folder, so put it inside iCloud Drive, Google Drive or Dropbox if you want it everywhere, and point Glowstone at it in Settings → Change folder.
