Answers come with receipts

Marella answers from your documents, not the open internet — and every answer carries citations that open the exact source passage, highlighted on the page it came from. If it can't evidence a claim, it says so.

Public chatbots answer from confidence. Marella answers from your documents, with the receipt attached — that's the difference your compliance team signs off.

Every citation previews its source on hover — document, pages, matches and the passage itself.

What does our retention policy say about client files after an engagement closes?

Client files must be retained for seven years after the engagement end date, then reviewed for secure disposal. Files under legal hold are excluded until the hold is lifted.

Every decision is on the record

Behind every answer sits a decision trace — which agents were selected, how each citation was judged, what the reviewer checked and why, each with its reasoning and confidence. Kept, so your auditors can replay it.

Provenance travels with the answer itself: which specialists contributed, and how many of its citations verified.

It builds your organisation's memory

Behind every conversation, Marella maintains a knowledge network — the people, companies, documents and topics your organisation deals with, linked into concepts and an ontology you curate and own.

Enterprise search finds documents. Marella understands what's in them — and remembers.

[ 03.A ]

Specialists, orchestrated

One conversation, many specialists: an orchestrator routes each question to the right agents — knowledge base, web research, calculations, document drafting — and each agent works at the autonomy level you set, from observe to autonomous.

Need depth? Deep research plans first, then works the corpus. Want control? Review the plan before anything runs.

AI your organisation can actually adopt: private enough for your risk register, evidenced enough for your board.

BAiSICS — AI legal platform

“Our system analyses large, complex and poor quality documents with remarkable accuracy, surpassing solutions like GPT‑4 and other AI legal tools.”
Christopher Wright Director, BAiSICS

Control your auditors will recognise

Departments, roles and permissions decide who can see and ask what. Decision traces record what the AI did and why; security events land in an immutable audit log — governance is built in, not bolted on.

Private by design, runs where your data lives

Single-tenant and self-hosted: your deployment, your licence, your model provider keys — so inference routes through accounts you control. Multi-factor authentication can be enforced org-wide, tracing stays off unless you switch it on, and your data is never used to train shared models.

OpenKit is ISO 27001:2022 certified (UKAS, cert no. 24112), ISO 9001 certified and Cyber Essentials assured — UK-based, UK-built.

Do our savings terms meet Consumer Duty outcome four?

Two clauses need attention: the fee disclosure in §4.1 predates the 2023 guidance, and §7 lacks the required value assessment.
