When Does Self-Hosting an AI Tutor Actually Pay Off?
The idea sounds appealing: your own AI model running on a server in-house, full control, and seemingly lower costs than the big cloud providers. But is that really the whole picture?
This calculator goes beyond surface-level price lists. It reveals the Total Cost of Ownership (TCO) — from expensive server hardware and hidden staffing overhead to the electricity costs nobody mentions upfront.
Enter your expected figures and find out at which point self-hosting genuinely pays off — and what price you pay for independence, not just in euros, but also in quality and scalability.
