Saperly, worked by an AI employee

Not another app for your team to learn, and not a set of rules for you to build. You hire an AI employee, you give it access to your Saperly account, and you ask it for things in Slack or Teams the way you would ask anyone else on the team. There is nothing to map and nothing to maintain.

  • Phone & SMS
  • Connects with a key
  • 30 ready-made tools

What Saperly is

Saperly is the phone carrier for AI agents — phone numbers, voice, SMS, and compliance in one API.

You paste in a key from your own Saperly account. It is kept encrypted, and you can withdraw it from inside Saperly whenever you like.

How a run works

One message in, the work done in Saperly.

  1. 01

    You ask

    You message your AI employee in the chat your team already has open, in one sentence, in your own words.

  2. 02

    It works out the step

    It decides what the job needs in Saperly. You do not pick anything from a menu or wire anything together.

  3. 03

    It does the work

    Signed in to your own Saperly account, inside the access you granted it, doing the thing you asked for.

  4. 04

    It reports back

    It tells you what it did, in the same thread. If it could not do something, it says so rather than guessing.

Questions people ask about Saperly

Can an AI employee really work inside Saperly?
Yes. It signs in to your own Saperly account and works in it the way a new hire would, from the chat your team already has open. Nobody installs anything, and nobody learns a new screen.
Do I have to move anything out of Saperly?
No. Nothing moves and nothing is replaced. Your records stay in Saperly, your team carries on in the same screens they used yesterday, and your AI employee works alongside them in there.
How does it get into my Saperly account?
You paste in a key from your own Saperly account. It is kept encrypted, and you can withdraw it from inside Saperly whenever you like. You approve it before anything connects, and you can take the access back the same way you gave it.
What can it actually do in Saperly?
It has 30 ready-made tools in Saperly today, among them Bind Connection to Number, Check Consent and Create Connection. The full list is on this page. It is not limited to those, but it never has to be taught them.
Can it use Saperly and the rest of my software in the same job?
Yes, and that is usually the point. Reading a message in one app, checking a record in Saperly and writing the result somewhere else is one request to your AI employee, not three separate ones you stitch together.
Who decides what it is allowed to do in Saperly?
You do. You grant access one app at a time and can withdraw it at any time, anything you ask it to check with you first it checks with you first, and everything it does in Saperly is written down with what it did and when.
