STONE
Up to 91%
less token usage
A compression architecture that reduces token usage in AI traffic by up to 91%. Lower cost and lower energy use per AI operation.
Data sovereignty
Your data stays in Europe.
Lexico Academy is hosted in the EU, runs on renewable energy and is built on an architecture that uses a fraction of the resources of ordinary AI platforms.
Hosting
Hosted in the EU, with Hetzner
All data and all processing for Lexico Academy stays within the EEA, in Hetzner's data centres in Germany and Finland. No data leaves Europe, and the platform is not exposed to the US Cloud Act. Data processing is GDPR-compliant, and a data processing agreement (DPA) is available.
EEA
All data is stored and processed within the EEA.
No Cloud Act
The platform is not exposed to US legislation.
GDPR
Compliant data processing with a DPA available.
Green AI
Compliance with a small footprint.
Hetzner's data centres run on renewable energy. But the biggest environmental gain lies in the architecture: the LexiCo ecosystem is built on STONE and an O(1) memory system that cuts computational needs dramatically. Less processing means lower energy use per course, per certificate and per AI response.
The technology underneath
STONE and O(1) memory
Lexico Academy runs on the same engines as the rest of the LexiCo ecosystem — built to make AI both cheaper and more resource-efficient.
O(1) memory (Lexi)
0.34 ms
recall at 1M conversation turns
A memory system that retrieves context in 0.34 milliseconds — even at one million conversation turns. Constant response time regardless of volume.
Try it yourself
Download Lexi Desktop Command
Lexi Desktop Command (LDC) is the desktop app that lets you use STONE and the O(1) memory directly on your own machine. Download it and see for yourself how few resources modern AI actually needs.
