Hey y'all! Logan here and it's my first time launching on PH 💪

So I built Thuki (Thư kí - Vietnamese for secretary) because I wanted a lightweight way to ask an AI a quick question without leaving what I was doing or paying for yet another subscription.

Double-tap `Control` key and it floats up right on top of whatever you're working on, even fullscreen apps. Highlight text on any app for pre-filled context, paste an image, or type `/screen` to instantly capture your full screen for even richer context.

Once Thuki's up, ask your question, get an answer, toss the convo, back to work. All in one Space.

Everything runs locally via Ollama, ships with Gemma 4 (Google's latest open source model) by default. No API keys. No subscriptions. No telemetry. No cloud. Your conversations live in a local SQLite database on your machine and nowhere else. Free and open source under Apache 2.0.

Built with Tauri v2, Rust, React, and TypeScript.

Still a WIP, but it works. And lots more features awaiting in the roadmap.

Would love your honest feedback! What would make this actually useful in your daily workflow?
