Frequently asked questions
Company context, plainly explained.
Sources, agents, editing, sharing, and pricing.
What is Substrate?
Substrate keeps company context for you and your agents. It reads Gmail, Notion, uploaded files, and your agent sessions, and keeps one current page per person, organization, project, product, repository, and routine. You can read and edit every page. Your agents get the relevant facts on every turn.
Who is it for?
Founders who have customers but no sales or marketing setup yet, and consultants or freelancers running several projects at once. Anyone who uses agents daily and is tired of re-explaining.
What does it cost?
Substrate is in open beta with one plan at $20 a month, everything included. Free and Pro plans are coming. There is no free tier or trial during the beta.
Which agents can use it?
Any MCP client, including Claude Cowork, Claude Desktop, Claude Code, ChatGPT, Codex, Grok, and OpenClaw, plus Hermes through the plugin. Connections are approved by you in the browser.
Which sources can I connect?
Gmail and Notion, both read-only, plus Markdown and text upload. Agent sessions are captured with your consent.
Can I read and edit the memory?
Yes. Every page is an editable document. Publish a change and it becomes a durable fact with the authority of a human. Deleting a sentence is a correction that stays in force.
How do I check where a sentence came from?
Each sentence is built from atoms that keep their source, date, and confidence. Agents can open the atoms and the original excerpt with one call.
Is every memory guaranteed to be correct?
No. Sources can be wrong and extraction can be wrong. Citations and confidence help you inspect a sentence; durable correction lets you repair it.
Can I share with someone else?
Yes. Share a page and everything under it with another Substrate user, live or frozen, with or without the raw files. Their agents see the shared pages and nothing else. Revoke at any time.
What happens to my data if I disconnect a source?
Nothing is deleted. Imported content stays, and Substrate stops syncing. Confirmed deletions in the source are marked no longer relevant.
