Desktop AI you actually talk to

DrLarz — your voice-controlled assistant for Windows.

Say "Hey Larz" and start a conversation. DrLarz hears you, speaks back, reads and writes your files, and runs every model through your DrLarz account — so the bill is predictable and the credentials never leave your laptop.

What it does

An AI that lives on your desktop, not in a browser tab.

🎙 Wake-word activation

Say "Hey Larz" anywhere on your machine. No tab to find, no shortcut to remember. The mic listens locally — your voice never leaves the box until you talk.

🔊 Spoken responses

Replies are streamed back through your speakers. Drive, code, cook — whatever you're doing, DrLarz keeps up without stealing your screen.

🛠 Local file tools

"Open my project. Find the file I edited last. Add a logging line near the error handler." DrLarz reads, edits, and writes on your machine — with confirmation prompts before anything destructive.

💸 One predictable bill

Every model call rides your DrLarz API key. Set a hard cap. Top up with crypto. Watch usage by alias. No surprise invoice on Monday morning.

🧠 Multiple model speeds

Pick Smart for thoughtful answers, Fast for snappy back-and-forth, Think for the hardest stuff. Switch mid-conversation.

🔒 You own the keys

Your API key sits in Windows Credential Manager. Your conversation history sits on your disk. No vendor account, no cloud lock-in.

Under the hood

Open, inspectable, no surprises.

DrLarz speaks the same protocol your other AI apps do — so the gateway can route your request to whichever model is cheapest, fastest, or just happens to be working. You never hardcode a model name and you never re-port your prompts when prices change.

Voice runs locally on faster-whisper; TTS uses Windows SAPI; tool calls go through DrLarz's confirmation layer before touching your filesystem. No phoning home, no telemetry you didn't opt into.
