# Sign in once at build.mixshift.ai and open your apps

build.mixshift.ai is the home for your MixShift apps. Sign in there once and that one sign-in opens all four apps that are open to every organization:

- **Intelligence Workspace**, which explains why your revenue changed. See [Use the Intelligence Workspace](/knowledge-base/intelligence/how-to/use-the-intelligence-workspace).
- **Forecasting**, a month-by-month revenue forecast you can correct. See [Publish and correct a forecast in the forecasting app](/knowledge-base/intelligence/how-to/publish-and-correct-a-forecast).
- **AMC Workspaces**, Amazon Marketing Cloud reports without SQL. See [Use AMC Workspaces](/knowledge-base/amc-workspaces/how-to/use-amc-workspaces).
- **Bid Engine**, Amazon Ads bids from one table. See [Use the Bid Engine](/knowledge-base/bid-engine/how-to/use-the-bid-engine).

The [apps page](/apps) lists all four with a link to open each one.

## Sign in

1. Go to [build.mixshift.ai](https://build.mixshift.ai) and choose **Sign in**.
2. Sign in with your MixShift account.
3. You land on the home page, where each app you can open has its own tile.

If you do not have a MixShift account yet, [contact support](/knowledge-base/shared/how-to/contact-support) and we will set you up.

## Open an app

Choose **Open** on an app's tile. The tile for the app you used last says **Continue**. Inside any app, the **Apps** menu in the bar at the top lists your other apps, so you can move between them without going back to the home page.

## Approve each app the first time

The first time you open an app, MixShift shows an approval page that names the app and lists what it does. Choose **Approve access**. It asks once per app, and it does not ask again unless you revoke the app.

## See what each app may do, and revoke one

On the build.mixshift.ai home page, **Apps and permissions** lists the apps you approved on this sign-in and the date you approved each one. Choose **Revoke** next to an app to end its access from this sign-in right away. The next time you open it, it asks for your approval again. Your other apps stay signed in. Inside any app, the person menu in the bar has an **Apps and permissions** item that takes you to the same place.

## The bar at the top of every app

- **Apps** switches between your apps.
- **Feedback** sends a note to the MixShift team. Choose **Something is wrong**, **An idea** or **A question**, say what is on your mind, and optionally add what you were trying to do. Inside an app, the note also carries the page you were on, so you do not have to explain where you were. A person at MixShift reads every note and replies to you personally.
- **Theme** is the sun and moon button. Each press moves between **System**, **Light** and **Dark**, and your choice is saved to your account so it follows you from app to app.
- **Your name** opens the person menu with your email and role, **Help**, **Apps and permissions** and **Sign out**. **Help** opens that app's getting-started guide in a new tab.

## Sign out

Signing out ends your MixShift sign-in on that browser. Your other apps ask you to sign in again the next time they refresh, within 12 hours at the latest.
