Our own AI product
Lyncat Tria
The AI we use to sort our own paperwork, now for the Mac: it reads invoices, payslips and contracts, names them and files them following your rules. It never deletes anything and everything can be undone. We designed and built it ourselves.
- Mac app
- Open-source engine
- Built-in AI or your own key
Agents and agentic systems
Specialised agents, orchestrated like a team.
We build agents that do one specific job —reading invoices, preparing reports, handling customers, keeping the CRM up to date— and connect them into an agentic operating system: an orchestrator that hands out the work, reviews every result and tells you when a human decision is needed.
- One role per agentEach agent does one thing and does it well. Easier to test, to improve and to replace.
- Whoever does the work doesn't sign it offA reviewer agent checks every result against the data before accepting it.
- You have the final sayHuman approval where it matters, a log of every action and cost limits. Nothing happens behind your back.
