Three things you can check before you rely on it

Open the source

A citation opens the page and passage an answer came from, so you read the document rather than a summary of it.

See what it decided

Decision traces record which agent ran, what it drew on and what it concluded.

Set the boundary

You choose where Marella runs and who can reach what, and we write it down before anything moves.

Cited answers

An answer you can open

Ask across the documents your team has approved. When the answer matters, open the citation and read the passage it came from.

Passage highlighting depends on the file type, so bring your own documents to the evaluation.

Traces cover the decisions listed in the evidence pack, not every access or model step.

Deployment

Managed, in your cloud or on your servers

Managed by us, in your own cloud account, or self-hosted on servers you run. Before anything moves, we write down where data is stored, which model processes it and who is responsible for what.

Access is limited to your organisation, and each document is marked private or shared.
