Show HN: I Built an Extension That Writes Emails in Seconds Using Gemini 2.5 Pro

After getting tired of spending 20+ minutes writing one email, I spent 7 days building a Chrome extension that helps me draft clear, confident emails in under 30 seconds — powered by Gemini 2.5 Pro.

I call it Email Draft Accelerator. It's a lightweight Chrome extension with a simple popup interface (popup.html, style.css, popup.js) and uses manifest v3.

It’s AI-powered by Gemini 2.5 Pro, but also supports Gemini 2.5 Flash, Flash-Lite Preview, and even the older 2.0 and 1.5 Pro versions (via API calls). No server—just local front-end + Gemini API.

Here’s how I use it daily:

I type a few ideas → it expands them into a full, personalized email.

I choose a tone (professional, casual, persuasive).

I tell it who I’m writing to → the AI adapts the message for them.

It helps me move fast, sound confident, and stop overthinking. Total game-changer for solo builders like me.

I’d love feedback from other developers who write lots of emails but hate the drag. You can try it here:https://chromewebstore.google.com/detail/email-draft-acceler...
