What if every object around you could teach you a language? CaiQi Talk lets you scan real-world objects to get vocabulary, then turns them into AI spirit companions for conversation practice. Generate stories from your daily words, track progress, and build fluency through natural interaction — not textbook drills. For learners who want to practice with the world around them, not just a screen.

Time is cultural — yet every app gives you the same Gregorian default. Era Workshop lets you build your own time layer: name your eras, mark special days ("Voyager Era, Day of Brilliant Dawn"), and visualize life as a personal historical scroll. AI-powered naming + multi-calendar support (Gregorian, Lunar, custom) included. For journalers, worldbuilders, and teams — because meaningful moments deserve names only you could give them.
