Hey r/tauri,

Sharing a Tauri 2 + React app I've been building: MelliLex, an MIT-licensed Windows desktop AI dictionary.

What it does differently from "wrap an LLM in a window" apps:

System-wide capture, no hotkeys. Ctrl+Right-click on any selected text in any app pops a lookup window — works in browsers, PDFs, Word, Electron apps, native Win32 controls.
OCR fallback for non-selectable UIs: Kindle desktop, Adobe Acrobat, Foxit, SumatraPDF, and Kindle Cloud Reader in the browser.
Bring your own provider: OpenAI, Anthropic, Gemini, or local Ollama
Structured output, not chat. Each lookup returns six rendered sections (meaning, usage, formality, domain, related words, common mistakes) plus an Explore mode with practice exercises.
Phrase + idiom support, not just single words.
Spell check before the request so typos don't waste a round trip.
Markdown + Capacities export so lookups become permanent notes.
Auto-updates via the Tauri updater.

Stack: Tauri 2, Rust , React + MobX, Vitest, SymSpell.

Happy to answer any questions about the project!
