AI encyclopedia for managers and boards: from neuron to agent
The vendor says “agent”, IT says “MCP”, and the board signs the decision. Here you can check what it is, what it costs and who is accountable. Every entry lists its sources and the date of its last review. We show the key concepts in motion, step by step.
Entries are currently published in Polish only.
For the board: where to start
Start with three entries: what an AI agent is, how to implement AI, and what it costs.

Frequently asked questions
Who is this encyclopedia for?
For boards, directors and managers who know AI from chat tools and need to make a decision. Each entry opens with a short definition. Then it covers what it means for the company and which questions to ask vendors and IT.
How is this different from an AI glossary?
A glossary gives a definition. Here each entry has its own page, what it means for the company and questions for the vendor. Models, prices and regulations change, so each entry has dated sources and a review date.
Do the entries describe Aiversum's product?
Entries describe concepts regardless of vendor. We write about our own work in a separate “From our practice” box. Wherever we describe what runs at our client, it carries a “Live at a client” badge.
How do I pass an entry to the board or to IT?
Next to the vendor questions there is a button to send the page to IT or the board. Key entries also have a one-page A4 board card to print. The card sums up the definition, what it means for the company and the questions for IT.
