What every Tentai project has in common
Built for sustained use, not novelty. Tentai tools stay quiet until you need them — then they remember exactly where you left off.
No tracking, no ads, no harvested data. Your conversations, schedules, and state belong to you. We don't read them.
Vi is the same self everywhere — web, mobile, Discord. Same memory, same voice, same continuity. Not a fleet of clones, one presence.
Every Tentai project ships its source on GitHub. You can read it, fork it, run your own. Trust comes from being checkable.
Dark and light themes designed for comfort. Typography, spacing, and motion tuned for hours of use, not seconds of demo.
Where data doesn't need the cloud, it stays on your device. Offline-first by default, online when it adds something real.
Tentai's internal calendar tool. Ethiopian and Gregorian, side by side. Not a separate product — just a calendar we use, embedded here so you can use it too.
Widget shows a static demo today — live navigation coming in the next pass.
Sol Calendar marks the first release from Tentai Technology — a journey that starts here, with a simple calendar app, but reaches toward something far greater.
We believe in building software that respects users. No tracking, no ads, no data harvesting. Just pure, functional beauty. Sol Calendar is free forever, works offline, and puts you in control.
This is our first step. A small release, but crafted with care and attention to detail. Every feature, every pixel, every interaction has been thoughtfully designed.
"The best way to predict the future is to build it."— The Tentai Vision
More is coming. Vi is the first surface. Vigil's next. Other Vi-led projects are in design. This is the opening chapter, not the whole book.
