Time Tracking Software

Harvest, 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 Harvest 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.

  • Time Tracking Software
  • Signs in to your account
  • 58 ready-made tools
  • Asked in Slack or Teams

What Harvest is

Harvest is a time-tracking and invoicing tool designed for teams and freelancers, helping them log billable hours, manage projects, and streamline payments

You sign in with your own Harvest account, the same way you already do. We never see or hold your password.

How a run works

One message in, the work done in Harvest.

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

  3. 03

    It does the work

    Signed in to your own Harvest 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.

Access, and who is in charge of it

You stay the boss of your Harvest 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 Harvest 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 Harvest is written down, with what it did and when.
  • Anything you tell it to check with you first, it checks with you first.

It works in Harvest 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 Harvest

Can an AI employee really work inside Harvest?
Yes. It signs in to your own Harvest 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 Harvest?
No. Nothing moves and nothing is replaced. Your records stay in Harvest, 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 Harvest account?
You sign in with your own Harvest account, the same way you already do. We never see or hold your password. 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 Harvest?
It has 58 ready-made tools in Harvest today, among them Create Client, Create Client Contact and Create Estimate. The full list is on this page. It is not limited to those, but it never has to be taught them.

Yes, and that is usually the point. Reading a message in one app, checking a record in Harvest 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 Harvest?
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 Harvest is written down with what it did and when.
