Exploring AI that respects your data.
A blog about artificial intelligence and digital privacy — written for people who want to understand both, use capable AI tools, and stay in control of their data. Posts here are practical and grounded: what is actually being built, what it means in use, and what is worth paying attention to.

Signal Replaces Telegram in Our Automation Stack
Until now, automated notifications from our AI workflows arrived on Telegram. It’s convenient, but it isn’t private: Telegram bot messages travel through Telegram’s servers in plaintext, with no end-to-end encryption at any point. We’ve now built our own Signal Messenger integration — self-hosted, running locally on our own server — to move these notifications, and…

We Audited Our Server and Closed Every Exposed Port
Running a self-hosted platform means the security of every service on it is entirely our own responsibility — there’s no cloud provider quietly patching things in the background. This week we ran a full audit of our server’s network exposure and followed it up with a hands-on remediation pass. The result: every service that had…

Testing Claude’s New Fable 5 on a Real Infrastructure Problem
When Anthropic released Claude Fable 5 in June, its first Mythos-class model made generally available, I had a task sitting on the shelf that felt like a fair test: a phone-to-AI-agent SIP bridge I had started, stalled, and restarted with earlier model generations more than once over the past few months. It never quite got…

Our Voice Agents Can Now Answer Calls
Phone calls have always been the one channel bacher-ai’s voice agents couldn’t reach — everything ran through the web app or the LiveKit Playground. That’s changed. A new SIP bridge now connects real phone numbers directly into the platform’s LiveKit voice agents, and the first agent built for it is already live: a phone-answering assistant…

LiveKit Is Now Live on bacher-ai
Real-time voice AI is no longer a cloud-only game. The bacher-ai platform has just deployed a self-hosted LiveKit instance — a significant infrastructure milestone that opens the door to a new generation of voice-driven AI experiences, all running under full data sovereignty. What LiveKit Is LiveKit is an open-source, WebRTC-based platform for building real-time audio…

Self-Hosting Your Git Repos with Forgejo
Most developers don’t think twice about pushing their code to GitHub. It’s convenient, it’s fast, and everyone’s on it. But convenience always comes at a price — and with code repositories, that price is handing over your intellectual property to a platform you don’t control. We recently completed the migration of our own repositories to…

Preparing for the Quantum Threat to Encryption
Quantum computers do not need to exist at full scale today to be a threat to your privacy today. That is the uncomfortable reality driving one of the most significant shifts in cryptography in decades. Governments, intelligence agencies, and well-funded adversaries are already collecting encrypted internet traffic — emails, VPN sessions, cloud data — with…

Run AI on Your Computer, Privately
Every time you type a question into ChatGPT or Claude, that conversation travels over the internet to a distant server — and stays there. It may be read by employees, used to train future AI models, or stored indefinitely. For most casual queries that might feel harmless. But when you ask an AI to help…

Protecting Kids Online Without ID Checks
Online age verification is having a moment. Governments around the world are pushing platforms to check users’ ages before granting access to adult content, social media, and other restricted services. The idea sounds reasonable — keep children away from harmful material. But the way most age verification systems work today creates a new set of…
