- <300ms
- added latency per prompt.
Problem
Every UK business has the same conversation in 2026. Staff are using ChatGPT and Claude because they make the work faster. The board wants a policy. Compliance wants an audit trail. IT wants something that does not require rewriting a year of working habits.
Blocking the public AI tools does not work — staff use their phones. SaaS-based DLP forwards your data through a third party. Running everything on local-only models means giving up the AI your team actually wants to use. The Trinito AI Gateway is the third option: a small appliance that sits in your office, watches what goes out, and removes what should not leave.
How it works
Three stages. One appliance.
-
Prompt
A staff member types in the Trinito chat window or via the browser extension.
-
Sanitise
The Gateway scans the prompt, finds confidential information, replaces it with placeholders, and shows the result for one-click approval.
-
Send and rehydrate
The sanitised prompt is sent to the chosen LLM. The response comes back, placeholders are restored, the user sees the original context.
What it protects

Who it is for

Recruitment
Sanitise candidate names, salaries and CVs before they reach the LLM — rewrite specs and screen CVs with confidence.

Customer story
"We could not block ChatGPT and we could not let staff keep pasting client addresses into it. Trinito is the only thing on the market that solves both."

Frequently asked
The five questions every IT buyer asks first.
Will it slow my team down?
No. The Gateway adds under 300 milliseconds per prompt on the default plan — most of which is the LLM you would have called anyway. Sanitisation runs on the appliance and is built to be invisible. The browser extension and chat UI both stream tokens as they arrive.
Can the redaction be trusted?
It is layered. UK-specific regex (postcodes, NI numbers, IBANs, Luhn-checked cards) catches the things you can write down. A local NER model catches names, organisations and places. A custom rule pack covers your specific client list. Every finding is logged. Every prompt can be reviewed before sending — by default on regulated tiers.
Which LLMs does it work with?
ChatGPT (OpenAI), Claude (Anthropic) and Gemini (Google) out of the box. Local models running on the appliance — Qwen, Llama, Mistral. New models added by the admin from a curated catalogue, or by bringing your own keys.
What happens if you go out of business?
The appliance keeps working. Local models run locally; your own OpenAI or Anthropic keys keep routing through the same redaction pipeline. The audit log is yours. We commit to a source-available fallback build for active customers if we ever close.
Is this for regulated industries?
The Sovereign tier ships with an air-gapped deployment option, suitable for FCA-supervised advisers, SRA-regulated firms, and healthcare admin. Audit logs are hash-chained on the appliance. Compliance can export the last 90 days as a signed CSV.
