Save anything.
Find it in seconds.
Forward links, posts, and files from any chat. Kasten turns them into one clean, searchable inbox automatically.

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.
Interactive demo: Kasten automatically organizes forwarded links and notes into searchable Spaces.
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.
