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. New accounts start with a 7-day free trial, no card needed. Free and Pro plans are coming.
Which agents can use it?
Claude Code, Cowork, Codex and Hermes get a plugin that adds memory to every answer. Claude, ChatGPT, Cursor, OpenClaw, the Grok CLI and other MCP clients connect by link and use memory when asked. You approve each connection in the browser.
Which sources can I connect?
Gmail and Notion, both read-only, and WhatsApp, linked from your phone by QR code. You can also upload documents, PDFs, spreadsheets, images, audio, video, archives, Markdown and text, up to 50 MB per file. 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, live or frozen, with or without the raw files. Invite people by email and they can view it, and their agents see the shared pages and nothing else. A page shared with "Anyone with the link" is public: no sign-in is needed, and search engines and AI assistants can index it. Revoke at any time; search engines and assistants may keep copies for a while.
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.
