SingleBrain Gateway

SingleBrain Gateway gives the assistant you already use one key to your own marketing accounts. Ask which pages lost traffic this week, and it pulls Google Analytics and Search Console and writes the answer in Claude, ChatGPT, or Cursor.

Free to start. Accounts you connect are not charged, and a new organization includes $5 in credits for paid tools.

Connects to Google Analytics, Search Console, Google Sheets, Slack, HubSpot, Stripe, Gong, Coda, Asana, OpenAI, and Perplexity.

For the team

What SEO and marketing ops use it for

The weekly question usually starts in Slack or a doc. Someone still has to open Google Analytics and Search Console and pull the numbers by hand.

SEO

Which queries lost clicks this week, and which pages drove them?

Your agent runs Search Console and Google Analytics and writes the brief. The brief names the page and the query.

Search Console Google Analytics

Marketing ops

What moved in the pipeline, and what did the calls say about it?

Your agent reads the HubSpot deals that changed and the Gong calls about those deals, then writes the summary in the chat where you asked.

Managed auth

OAuth, refresh, and revocation, handled. You grant access, and you can revoke it.

Nothing crosses between organizations

Each organization is separated in Postgres. A query for another organization's accounts returns nothing.

Questions

Common questions

What can the key reach?

Only the accounts your organization connected, and only the access you granted. Accounts you did not connect are not listed.

Do you store our data?

We store the encrypted credential and a short record of each call: who asked, which service, and what kind of request. We do not store the data that came back.

Can one customer's accounts be read by another?

No. Each organization is its own tenant. Row-level security in Postgres refuses a cross-organization query, and the application connects as a role that cannot bypass it and has no schema rights. Credentials are encrypted with AES-256-GCM, bound to the organization and the service. SOC 2 is in progress. The tests run against a real database as both roles.

What does Slack do here?

Mention the assistant in Slack and it replies in that thread. That reply does not pull your other accounts. The key you paste into Claude, ChatGPT, or Cursor can read Slack. It does not post, upload files, or add reactions.

How does this relate to a Single Brain deployment?

Single Grain sells managed revenue agents. The Gateway is how one reaches your accounts. This site is shared, and each organization is separated in the database. A dedicated deployment runs on infrastructure nobody else shares, for agents that act and not only read.

One key, and your agent finishes the job.

Connect an account, take a key, and ask the question in the agent you already use.
