KASANERU LAB
Calm, Notion-native tools
KASANERU LAB is a small software studio based in Japan. We build calm, beautiful tools around Notion that let you layer your daily notes, learnings, and thoughts naturally. Everything our products create stays in your own Notion.
What we care about
Designed to be calm
No notifications, no ads, no clutter. We build quiet tools that stay out of the way of your day.
Your data stays yours
Everything you write is saved into your own Notion. We never hold your notes on our servers.
Layer your days
Small entries quietly add up over time, becoming a record that is truly your own to look back on.
