The same Synantic in every case — the same citations, the same approval step, the same permissions. What changes is where your documents sit and whose model keys answer the question.
Create a workspace and start on the free plan. Nothing to install and nothing to keep patched. Each organization's data is isolated from every other one, and the plan you choose is the only thing that differs.
Best for a team that wants the product rather than the infrastructure.
The same build, as containers on your own machines or inside your own cloud account. Kubernetes manifests and Compose files ship with it. Your documents never leave the network you put them on, and storage is your own disk rather than a plan limit.
Best for a data residency rule, an air gap, or a security review that ends with “not off-site”.
Point it at your own OpenAI, Anthropic or Google account, so model usage bills to you directly under agreements you already signed. Or serve the small, frequent calls from a model on your own GPU, and most of the work never crosses a network at all.
Best for an existing provider contract, or a privacy floor you set yourself.
The question every security review asks, answered plainly for each combination rather than left to a diagram.
| Setup | What leaves |
|---|---|
| Managed cloud | Your documents are stored by us and model calls are made by us, under the permissions and policies your organization sets. |
| Your infrastructure, hosted models | Documents stay on your disk. What goes out is the text of a question and the passages needed to answer it, to the provider you chose. |
| Your infrastructure, local models | Nothing goes out. Retrieval and generation both happen on hardware you control. |
Every answer cites the sources it came from and you can open them. Nothing is sent, booked or replied to until a person approves it. Permissions and policies are your organization's, and every action lands in an audit trail. None of that is a tier you buy — it is the product.
Managed cloud is self-serve: create a workspace and start on the free plan today. On-premise and bring-your-own-key deployments are part of the Enterprise plan, priced against the deployment rather than a list, because its shape is the price.
