The Brain / Compare / Build your own
2026Updated 15 September 2026
You can build this. It costs someone a year.
Elasticsearch, a vector database, a RAG framework or an agent framework and a team: every competent platform group raises it, from public product information, not a controlled test.
The short answer
Building your own gives full control, data sovereignty, model choice and no licence dependence. The Brain skips the year of connectors, permission work and evaluation that never finish, and judges from day one.
Six rows to cost before you commit
Bold is our row, the right column is the honest cost of the alternative.
| The Brain | Build your own | |
|---|---|---|
| Time to something real | A two-week Diagnostic Sprint, then a build at $30K–$100K fixed | A demo in weeks. Trusted writes take much longer |
| Connectors | Built from what your systems already record | Yours to write and keep working |
| Permission fidelity | It can only act as the person who signed in. Nothing in a document, an email or the AI’s own output can change that | The hardest part, discovered late |
| Judgment and interruption | Built in. It decides what is worth your time and sends a short ranked list | Rarely built. Most projects stop at retrieval |
| Action layer and approvals | Built in. Anything that sends, deletes or shares waits for a yes | Every action is yours to implement, secure and approve |
| Control and sovereignty | Data scoped to your organization, never used to train third party models | Complete. If it is a hard requirement, the strongest row |
Component rows reflect public capability, not a controlled test. Your build will be as good as the team you put on it.

Questions buyers ask
Is building your own or WorkElate Chief better for a 500-person company?
If sovereignty is a hard requirement or this capability is your product, build it, and use our rows as the requirements list. If you want it judging in weeks, the Brain, because the connectors, the permission work and the evaluation suite are the year most builds never finish. At 500 people, that year is usually your best engineer's.
Can I use what I built and the Brain together?
Yes, where your own system records something the Brain can read. The Brain reads what a connected system emits, and a service you built that records its changes is one such system; connecting it is engagement work in the Sprint, not a switch in a settings page.
What does building your own cost?
A demo in weeks; trusted writes take much longer. Cost the connectors, the permission work and the evaluation suite before you start, since those are the rows most projects discover late.
What does the Brain cost?
A two-week Diagnostic Sprint first, then a fixed build of $30K to $100K on your stack. The Sprint fee is not published; it is scoped on the first call, and the build price is fixed before it starts.
