Features

Everything you need.
Nothing that shouldn't be there.

Four integrated modules, built for regulated professional practice — not for the generic enterprise.

E2EE messaging
Encrypted conversations and attachments. Zero metadata exposed to the server.
Files & mandates
Role-based access control, full history, encrypted vault per file.
AI concierge
Summaries, drafting, research — without ever leaving your network.
E2EE calls
End-to-end encrypted audio and video. External clients join without a third-party app.
Why it matters

Practice without wondering
where your data goes.

The invisible risk
Your current tools are American
Slack, Teams, Google Workspace — subject to the CLOUD Act. The US government can access your data without notifying you.
Your obligation
Professional secrecy doesn't negotiate
For a lawyer or a physician, a client data leak isn't an inconvenience — it's a real disciplinary risk.
The AI problem
ChatGPT may have seen your files
Every cloud AI request transits through foreign servers. Without your clients' explicit consent, that's a potential Law 25 violation.
The Tisio answer
Everything stays within your walls
The app, the AI, the files — hosted on your infrastructure, in Canada, under your physical and legal control.
"The majority of our data used in AI leaves our borders or is governed by other countries' privacy regimes."
— Prime Minister Mark Carney · National AI Strategy · June 4, 2026

Frequently asked questions

What we get asked
most often.

Tisio is a mobile app combining encrypted messaging, client files, calls and an AI concierge for regulated professionals. It connects to the sovereign infrastructure deployed in your firm by Silio rather than to an external cloud: your data never leaves your walls.
Yes, and it goes further. Tisio covers the same ground: messaging, team channels, department groups, audio and video calls. On top of that comes something no office suite offers — a workspace per file: the mandate, the patient, the client. Each with its own encrypted vault, role-based access and complete history, even when the file brings together people from several departments. Plus an AI concierge that reads that specific file to summarize, draft or retrieve a clause, without anything leaving your network. Then there's the legal question: Slack, Teams and Google Workspace are American services subject to the CLOUD Act. For a professional bound by secrecy, that isn't a technical detail.
No. The AI concierge runs on the infrastructure deployed in your firm. Summaries, drafting and document search happen without your file contents leaving your network — unlike a request sent to a cloud AI service, which transits through foreign servers.
Tisio is designed for professionals bound by a legal duty of confidentiality in Quebec: lawyers and notaries, physicians and clinics, accountants and CPAs, and independent pharmacies.
