Show HN: Echodot – Local-first AI that writes replies in your tone

I built echodot – a free, open-source desktop app that drafts replies in your personal writing style. Problem: Most AI writing tools either force you into their voice or require constant copy-pasting between apps. Tools like Cotype are useful but closed-source and cloud-only. What echodot does: - Press a global hotkey (⌘⇧E / Ctrl+Shift+E) - It reads the context (from clipboard) - Generates a reply that matches your tone - Auto-copies the result so you can paste it instantly Key points: - Local-first by default (works with Ollama) - Optional OpenRouter support (bring your own key) - Tone presets + writing samples for better personalization - Streaming responses - Completely free and MIT licensed - No account, no tracking, no subscription Tech stack: Tauri 2 + React + TypeScript + Tailwind Rust backend for hotkeys and system integration GitHub: https://github.com/ohkariku-boop/Echodot https://github.com/ohkariku-boop/Echodot Still early (v0.1). Looking for feedback on the core workflow, prompt quality, and what features would make this actually useful day-to-day.
