Your sector. Your data.
Your hardware.

A privacy-first option for the security-conscious: run NTLSN’s tools — and an open-source AI assistant — entirely on your own machine or campus. Nothing is sent to, or stored by, anyone. Built for individuals and schools who need genuine data sovereignty and a clean IT review.

Personalise it — two ways in

👤

For an individual

Download it; run it on your own laptop. The tools work offline. Add a local open-source model and your AI teaching coach runs on your machine — your drafts, your students’ work and your reflections never leave it.

🏫

For a school

Host the whole suite on one high-end on-prem machine. A single open-source LLM serves the school; IT keeps full control and can run it fully air-gapped. No cloud contracts, no data-residency questions, no per-seat AI bills.

How it stays private

Why IT and leadership say yes

Data sovereigntyStudent work, assessments and peer reviews never touch a third party — Privacy Act 1988-friendly by design.
A clean IT reviewNo external data processor to vet; open-source and auditable, not a black box.
No lock-in, no token billsYou own the model and the data — predictable, with no per-use AI charges.
ResilientWorks offline and isn’t dependent on any vendor’s uptime or pricing.
Already half-real, today. The privacy claim isn’t marketing — every tool in the NTLSN toolbox already runs 100% in your browser with nothing sent or stored. This concept simply packages that local-first suite together with a self-hosted open-source AI coach as a one-box option you own.

Concept / in design. This articulates an option, not a shipping product. The client-side tools are live now; the self-hosted open-source-LLM bundle, on-premise hosting and air-gap mode are on the roadmap — scoped and sized to your hardware (and any cost) with you, never assumed. Nothing on this page is collected, stored or sent.
