Compare who owns the reference with who owns the agent’s behavior.
A team agent needs both useful references and a clear job. Dust documents customizable agents with instructions and tools over company data. Include HeyBrain when you want to evaluate a separate knowledge reference for an AI workflow you already use. Consider how much agent behavior you need to configure and maintain alongside the knowledge. Do not assume that one product automatically makes the other governed. Method: primary vendor documentation reviewed on 6 October 2026; no hands-on head-to-head benchmark. Diagrams are fictional evaluation examples, not product screenshots or measured results.
In a fictional campaign workflow, a reference owner approves the brief while an agent owner maintains instructions and tools. Record both responsibilities. A current brief does not guarantee a good draft, and a polished agent does not fix a stale brief.
Ask for a draft based on an accepted reference. Review its evidence and then inspect whether the workflow can take an external action. Consultation and publication need separate acceptance criteria and authorization.
Evaluate Dust first when the task involves configuring and sharing a specialized team agent. Its documentation describes agent instructions and tools; test the configured job rather than expecting default behavior to fit every workflow.
Not necessarily. Start with the failure you want to fix: missing references, inconsistent instructions or an action the workflow cannot complete.
Use the same owned brief to compare a reference lookup and an agent-generated draft. If the lookup solves the problem, additional agent configuration may add little. If the job needs maintained instructions and tools, evaluate those explicitly.
Dust documents open and restricted spaces, with agent availability tied to the spaces used by its tools. Do not treat that description as proof that every source permission is inherited unchanged.
Record intended space members and agent users. Test a harmless restricted reference with an allowed and excluded reader, then remove access and record what changes. Apply comparable checks to the actual HeyBrain workflow.
Only if a specific integration is supported and verified. This comparison demonstrates neither a HeyBrain-to-Dust connector nor a combined permissions boundary.
First decide whether you need both a separate reference service and an agent platform. Evaluate the data flow, exposed tools and ownership before combining them; adding a second system also adds operating and access-review work.
Dust’s builder documentation includes tools alongside instructions. Treat a tool’s ability to perform an action as a separate boundary from its ability to consult knowledge.
For a fictional campaign task, accept a source-backed draft before permitting any publication. Record the destination, approver and expected effect for a write test. Use only an authorized disposable fixture; this page claims no tested write-back capability for HeyBrain.
| Attribute | HeyBrain | Dust |
|---|---|---|
| Primary evaluation | A separate knowledge reference for the existing AI workflow you choose. | Customizable team agents over company data. |
| Behavior ownership | Determine where instructions, drafting and actions are configured in your chosen client. | Agent creation includes instructions and tools. |
| Team access | Require observed reader and access-removal behavior for your configuration. | Open/restricted spaces and space-linked agent availability are documented. |
| External action | Knowledge consultation does not establish source write-back or publication support. | Evaluate each configured tool and its separate authorization. |
| Combined deployment | Do not assume an available HeyBrain-to-Dust integration or shared permissions boundary. | A combined workflow needs a verified integration and clear operating owners. |

Dust documents customizable team agents over company data and an agent-building workflow with instructions and tools.
Dust’s agent-creation guide describes setting instructions and configuring tools for an agent.
Dust documents open and restricted spaces, administrator-managed access and agent availability linked to the spaces used by its tools.
HeyBrain publishes its processing and storage of submitted content in its privacy policy; policy text is not an independent access-boundary test.
Choose an owned fictional brief and assign a reference owner and an agent owner. Ask each candidate for the current reference and, separately, the draft you need.
Record source edition, human corrections, excluded-reader behavior and the actions available to the workflow. Choose based on the job you can operate responsibly, not an untested promise that combining tools makes every agent secure.
