Just 3 seconds. No complicated editing — your daily vlog, effortlessly stylish. For your own record, or to share with family and friends. This is kirok. "I want one habit that actually sticks." "I take photos, but I never look back at them." "I want to stay loosely connected with someone far away." All of that, in 3 seconds. ■ Three ways to use it. All free. [Solo vlog] Capture the moment in 3 seconds. As many times a day as you like. Every clip stays in your library, ready to revisit anytime. [Themed Solo Rooms] Your cat. Gym. Meals. Your kid growing up. A trip. Make a private Room for each theme and collect only what fits. Just for you. No one else sees it. [Group Rooms with friends, partners, family] Share your daily 3 seconds on an invite-only timeline. Everyone's "today" lines up by time of day. Use it only when you feel like it. Shared videos auto-delete after 7 days. Toss them in, let them flow. Save what you want to keep to your own library. ■ How people actually use it Solo: - A small daily record - A Room dedicated to your cat - Daily running or workout logs - Daily food and cooking logs - A Room collecting 3 seconds from each trip - Watching your kid grow up With others: - Trading daily 3 seconds with a long-distance partner - A family group sharing daily moments with parents back home - Daily vlogs with your closest two or three friends - Sharing events and gigs with hobby friends ■ Why 3 seconds? Short enough to keep going. Short enough to stay fun. Tap, and it stops by itself — no overthinking the shot. But when you look back, the feeling of that moment is still there. ■ What happens after you record? It's saved. That's it. No filters. No trimming. No music picker. No sound. Zero time spent deciding — that's why it sticks. Silent by design, so you can share to social without asking anyone to unmute. On the train, in bed at night, next to anyone. ■ recap Stitch your kirok clips into one continuous video. Today, a week, a month, a year, or your whole life in kirok — pick any range.
