What is Trueears?

Trueears is a minimalist, context-aware AI voice dictation application built with Tauri and Rust. It runs as a lightweight background process (<15MB RAM) and activates with a global hotkey.

When you press Ctrl+Shift+K, Trueears:

1. Detects your active application (VS Code, Slack, Outlook, etc.)
2. Records your speech via the Web Audio API
3. Transcribes it using Groq’s Whisper API
4. Optionally formats the text with an LLM based on the active app context
5. Pastes the result directly into your focused text field

No switching windows. No copy-paste. Just speak and keep working.

Key features
