PulseTimer – AI-Powered Work Timer with Smart Presets and Privacy-Focused Design

Hey HN,

I built PulseTimer, a clean, responsive work timer that uses AI to recommend optimal session settings based on your goals. Whether you're studying, coding, exercising, or in meetings, it gives tailored Pomodoro-style presets to help you stay focused.

Why I made it: I was tired of rigid timer apps. I wanted something fast, private, pretty — and smart enough to adapt to what I’m working on.

Tech:

    Frontend: Vanilla JS, HTML5, CSS3

    Backend: Node.js + Express

    AI: OpenRouter GPT-3.5 API

    Audio + Notifications: Web APIs

    Privacy: No tracking, no accounts, all data stays local
