Trained on your knowledge. Answers with sources.

Pull in a PDF, website or Notion export — your bot answers from your content and shows where each answer comes from. Watch a few example questions roll through.

The best available answer,
not the cheapest model

Many tools train a cheap in-house model and call it AI. Zeptix routes every request to leading AI labs and wraps complex topics in a clear, simple conversational style. When limits hit, a fallback steps in seamlessly.

Zeptix is the project I've put the most of myself into — a full multi-tenant AI platform where anyone can turn their knowledge into a hosted, branded chatbot without writing a line of code. Behind the simple "go live in minutes" promise sits a real engineering stack: a retrieval pipeline over PostgreSQL with pgvector, smart routing across four frontier model providers, per-tenant branding and billing, EU hosting and a transparent data-protection architecture.

Today, June 1, 2026, the first public version — v0.01 — goes live. It's an early, honest first step, and I'm genuinely proud of it. Read the full launch story →
