We Redefine How We Work
Forty years of staring at screens is enough. Tjess is a personal AI assistant that gives you back your time and helps you focus on what matters.
The Product
Tjess. Your own AI assistant.
Deploy a personal assistant that reaches you via phone, Signal, email, and the Tjess app. Set it up in three minutes. Everything included.
Ready in three minutes
Install the Tjess app on your phone. Connect your AI model. Start working. No infrastructure to manage.
Phone, Signal, email, app
Your assistant reaches you through the channels you already use. Start a conversation in one, continue in another.
Your data stays yours
European infrastructure, full data sovereignty. We do not train on your data and we do not sell it.
Lightweight by design
Built in Rust to run on minimal resources. Lower cost for us means a better product at a lower price for you.
Why We Exist
Give people their time back
Most technology is built to take your attention. We are building the opposite. An assistant that does the work so you can be present for the things that matter. Your family, your health, your growth.
Less screen, more life
Every feature we build is measured by one question: does it give you back time? If it does not, we do not ship it.
Your workflow, your choice
Tjess adapts to how you work. Bring your own models, set your own rules. No one-size-fits-all.
The best product wins
No shortcuts. We are building the most reliable, most thoughtfully designed AI assistant on the market. That is how we plan to earn your trust.
Based on academic research into screenless work.
What Makes Us Different
Not just faster. Better.
Most AI assistants do your work for you. Tjess does that too. But it also helps you get better at what you do.
Most assistants
Do the task, move on
You give it work. It finishes. You give it more. The output goes up but you stay the same. The task gets done, but nothing changes about how you work.
Tjess
Do the task, grow from it
Your assistant knows what you are working toward. Sometimes that means handling the task. Sometimes it means leaving it to you, because doing it yourself is how you get better.
An assistant with a wider view
Tjess does not just look at the task in front of it. It holds your direction. What you want to learn, what you want to spend your time on, what you want to get better at.
Efficient by design
We do not sell tokens. We sell the platform. So we are incentivised to make your assistant efficient, not chatty. Your interests and ours are the same.
You own everything
Your data, your model choice, your goals. All stored on European infrastructure. Nothing locked in, nothing hidden, nothing trained on.

Channels
The minimum you need. Nothing more.
Phone, SMS, Signal, email, and the Tjess app. These are the channels that matter. We are not building integrations for the sake of a feature list.
Works on any connection. Bad signal? Tjess works over SMS just as well. No app required for the basics.
Signal over noise. Your assistant handles the routine and only reaches out when something needs your attention.
Jump in, step back. Take over when you want to. Hand it back when you are done. You stay in control.
