● NTLSN · Concept · in design
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
Local-first tools Live today
Every NTLSN “try it now” tool already runs entirely in your browser — open one and turn off your wifi; it still works. That is the foundation everything else builds on.
Your own open-source LLM In design
Open models (e.g. Llama, Mistral, Qwen) run on your hardware via tools like Ollama or llama.cpp — no commercial AI API, no prompts or data leaving your network.
On-premise hosting In design
Serve the suite from a local server or workstation; staff reach it on the campus network, or each person runs it locally. No public internet required.
Local storage, your files Live today
Records stay on the device or your own server. You own the files; there is no NTLSN account and no server-side copy.
Air-gap capable In design
For the most sensitive settings, it can run with no internet connection at all.
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.
