Hey Product Hunt! 👋

I'm the creator behind Stellisle (知屿星信).

I started this project because I wanted a calm, conversational presence on my desktop—something that sat quietly in the corner of my Mac, truly remembered small milestones across weeks and months, and never asked me to surrender my privacy to an external API.

A few engineering choices we committed to from day one:

1. Zero Cloud Telemetry: When you unplug your Ethernet and turn off Wi-Fi, Stellisle still operates.

2. Tactile Craftsmanship: Instead of another sterile SaaS form, we built a physical dot-matrix teleprinter desk where every mechanical stepper motor hum, needle impact, and paper feed friction is synthesized via real-time Web Audio math.

3. No Subscription Lock-in: Desktop companion software should feel like a reliable possession, not an ongoing rental.

Today, we've opened our interactive web portal and Starlight Atelier on Cloudflare Pages so you can test the interaction design and generate keepsake cards directly in your browser:

I would love to hear your thoughts on the card studio, the teleprinter acoustics, or our local-first approach. Any feedback, questions, or critiques are warmly welcomed! ✦
