Kosu

A mindful content queue

Engage with what matters or let it fade away

Like filtering coffee — slow, intentional, keeping only what passes through. If you don't engage, it fades. No hoarding. No guilt.

Single queue

No folders. No categories. Just one stream of what you saved.

Visual fading

Items fade over time unless you engage. Your attention decides what stays.

API-first

Built for AI agents. Your assistant can read and manage your queue.

Save less, engage more.
