AI Content Generation

Captions, 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 Captions 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.

What Captions is

Captions provides the Mirage API for generating videos and speech and adding styled captions to videos.

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

How a run works

One message in, the work done in Captions.

  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 Captions. You do not pick anything from a menu or wire anything together.

  3. 03

    It does the work

    Signed in to your own Captions 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.

8 tools it already has

What it can do in Captions

These are the ready-made tools your AI employee already has in Captions. It is not limited to them, but it never has to be taught these.

Access, and who is in charge of it

You stay the boss of your Captions account.

Nothing connects until you approve it. You grant access one app at a time, you can take it back the same way, and everything your AI employee does in there is written down where you can see it.

How we handle your data
  • It signs in to your own Captions account. You are not moving anything into ours.
  • You grant access one app at a time, and you can take it back the same way.
  • Everything it does in Captions is written down, with what it did and when.
  • Anything you tell it to check with you first, it checks with you first.
Other apps in the same corner of the business

It works in Captions and the rest of your software in the same job

A real job rarely stays in one place. Reading a message in one app, checking a record in another and writing the result in a third is one request to your AI employee, not three.

Questions people ask about Captions

Can an AI employee really work inside Captions?
Yes. It signs in to your own Captions 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 Captions?
No. Nothing moves and nothing is replaced. Your records stay in Captions, 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 Captions account?
You paste in a key from your own Captions account. It is kept encrypted, and you can withdraw it from inside Captions 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 Captions?
It has 8 ready-made tools in Captions today, among them Add Captions, Download Video and Generate Speech. The full list is on this page. It is not limited to those, but it never has to be taught them.
Can it use Captions 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 Captions 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 Captions?
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 Captions is written down with what it did and when.
