Rulebook vs Agentforce and HubSpot Agent Hub

Agentforce is the agent product of Salesforce, and Agent Hub is where HubSpot runs its agents. Rulebook is an AI work agent that works with HubSpot or Salesforce and also in Slack, Gmail and Google Drive. It finds the work in your meetings and requests, asks the owner and checks each change in the tool.

What Salesforce and HubSpot say on their own pages

What Rulebook does today

The same five questions on each compare page. These results come from Brightloop, our demo company with synthetic data, on real HubSpot, Salesforce, Slack and Google accounts. They are not results from customers.

Where does the work come from?

From meeting transcripts, Slack request channels and direct messages, inbound email and the regular tasks in your playbooks. Rulebook finds the work by itself: nobody has to write a prompt.

Live-checked: a regular task made a usage summary with 8 of 8 numbers right

Who approves a change?

The owner of the work item. By default, Rulebook asks the owner before it changes a record. It always asks a person before it sends an email to your customers or does a legal or financial step.

Does it do the work in your tools?

Yes: in HubSpot, Salesforce, Slack, Gmail and Google Drive, Docs and Slides. See the integrations.

Live-checked: a Slack request changed a deal amount in HubSpot and in Salesforce

How do you know that it is done?

Rulebook reads each change back from the tool. The work is done only when the values match, and each run keeps a receipt.

Live-checked: the values read back from HubSpot matched, 3 of 3 receipts complete

Where does each fact come from?

Each fact cites its source. A second model checks each claim, and a fact with no source becomes "Unknown: needs a human". See the trust page.

Live-checked: a planted false price was blocked in a follow-up email

Which one fits your team

If your work lives in one CRM and you want agents that the CRM vendor builds and supports, look at the agents of your CRM. If you want the work from your meetings, Slack and email to be done across your CRM, inbox and documents, with the owner's approval and proof, that is what Rulebook does.
