How it works

Three steps. Then it just works.

01

Send it from wherever you are

Forward a link, screenshot, voice note, or idea from Instagram, WhatsApp, Telegram, SMS, or any chat you already use. No new app to learn.

02

It organizes itself

Kasten adds a title, tags, and a one-line summary. Everything lands in a clean, searchable archive. Status labels keep you oriented.

03

Find it by just describing it

Search by topic, how you remember it, or where it came from. No folders required. Nothing is ever lost.

Your inbox

Every saved thing, organized the moment it arrives.

One place for every link, note, screenshot, and idea you have ever forwarded to yourself.

Privacy

We only ever see what you forward. Nothing else.

Kasten never reads your conversations. It only receives the specific messages you choose to send to your inbox. Your privacy is not a feature. It is the foundation.
