Grow your existing customers.
Every customer gets a page that stays current: what they asked for, what is blocked, what changed since you last looked. Renewal risk stops hiding in a thread.
Three sources. One page.

What it does for you
Your next customer may already be in your inbox.
People who write to you become pages too, with what they wanted and when. Nothing to file.
Stay on top of your tasks.
Open tasks, decisions, and procedures are collected as Routines, one page each, from the same sources.
Right now, your context is scattered.
The renewal risk is in an email. The decision is in a Notion page. The workaround is in yesterday’s Claude session. Your agents start every session without any of it, and so do you when you switch tasks.
Your agents aren't forgetful. They just have nowhere to remember.
The artifact
The page you never had to write.
One page per entity — a client, a project, a codebase, a person you work with. It reads like a document you'd be proud of. You didn't write a word of it.
Every sentence is a verified fact, distilled from your real sources. Hover any sentence and its evidence unfolds: the email it came from, the Notion page, the session — each one dated, each one scored for confidence.
It's not a search result. It's not a transcript. It's the current state of what you know, written down.
How it works
One loop. It runs while you work.
Capture.
Gmail, Notion, uploaded files, and your agent sessions stream in as you work. Every source is kept exactly as it arrived.
Distill.
Sources are broken into atoms: people, organizations, projects, tasks, decisions. Each atom keeps its evidence, its date, and its confidence.
Correct.
Each page is a clean document. When something is off, you edit it and publish. Your edit becomes a durable fact with the authority of a human.
Recall.
The next time any of your agents starts a session, the relevant facts are already in its context. It begins knowing.
Every day you work makes every future session smarter.

Every sentence shows its work.
Hover any sentence in a summary and its sources unfold — dated, with confidence. If a fact is wrong, correct it once; the correction is durable and your agents use it from then on.

Sharing
Share a branch, not your whole memory.
Pick a page and share it, with everything under it, to another Substrate user. They and their agents see exactly what those pages say and nothing else. Keep it live or freeze it. Take it back at any time.
