About SchweizGPT

SchweizGPT is a Swiss-first digital reference and utility hub: 15 deterministic statutory calculators, 12 private in-browser file utilities, the verified Top 100 Swiss AI Directory, 10 live public Swiss data feeds, and a keyless REST API and 23-tool Model Context Protocol (MCP) server (schweizgpt).

Every calculator runs deterministically on published federal formulas (ESTV, BSV, BAG, BJ, SECO, SEM, SIX, SBB) and links directly to its primary source. Every browser file utility runs locally on your device so confidential documents never touch a remote server.

Built in Zurich

SchweizGPT is built and maintained in Zurich by Terence La (AI Lead at Zurich Airport & Founder of Leistera).
