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

Developer ohkariku-boop released echodot v0.1, a free, MIT-licensed, open-source desktop app that drafts replies in a user's personal writing style via a global hotkey (⌘⇧E / Ctrl+Shift+E) that reads clipboard context and auto-copies the generated result. Echodot runs local-first by default with Ollama and offers optional OpenRouter support with a user-supplied key, plus tone presets and writing samples for personalization, streaming responses, and no account, tracking, or subscription. Built on Tauri 2, React, TypeScript, and Tailwind with a Rust backend for hotkeys and system integration, the app is positioned as an alternative to closed-source, cloud-only tools such as Cotype, and the developer is seeking feedback on the core workflow and prompt quality.

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.
