Show HN: Notestorm – a privacy-first AI scratchpad I made for quick idea dumps (opens in new tab)

Hey all, I made simple note app for quick note-taking with AI text completion (just like GitHub Copilot) to get contextual writing suggestions that match the tone and voice.

I skip words or sentences often when I brainstorm. They're on the tip of my tongue but won't come out, and by the time I find them, I've lost my train of thought. So I made Notestorm where I can continue writing without breaking the flow.

Features: - Clean, markdown editor with VSCode keybindings - AI autocomplete that mirrors your writing style - Local-first. Notes saved in IndexedDB, no servers, no accounts - Works offline. nothing leaves your machine unless you use your own API key.

I use it for: - Brainstorming ideas before they're ready for my "real" notes - Drafting emails/messages quickly (then copy to Gmail) - Any temporary writing that I'll delete after copying elsewhere

Try demo (GPT OSS 20B 128k) or use your own key (OpenAI/Anthropic/Google/Groq).
