Building a privacy-first, EU-hosted AI chat in Rust (Leptos)

Hi HN,

I’m a DevSecOps based in London. I’ve been getting increasingly frustrated with the "black box" nature of current AI chat tools, specifically regarding data sovereignty and GDPR compliance (I work in RegTech, so I’m paranoid by trade).

I decided to build a European alternative that doesn't route prompts through US servers.

The Stack:

- Core: Rust

- Frontend: Leptos (WASM) - wanted to try something other than the usual React bloat.

- Infra: Cloudflare Workers (trying to keep it edge-based).

- Models: Strictly EU-hosted inference.

Current Status:

I have the auth flow and basic infrastructure up. I threw together a landing page (yes, the design is a bit "AI-vibed" while I work on the backend) to see if others actually care about this, or if I'm just shouting at clouds.

I’m looking for feedback from European devs/users: Does "Data Residency" actually matter to you for personal use, or only for B2B?

Link is above if you want to follow the progress.
