# What Applane is

> Applane is a Chrome extension that turns a plain-language description into an internal web app deployed to Google Apps Script in your own Workspace.

Source: https://docs.applane.dev/

Applane is a Chrome extension. A person on your team opens its side panel, describes an internal tool in plain words, and iterates with an AI agent until a working web app is deployed.

The app runs on Google Apps Script, inside your Google Workspace, under the account of whoever opens it. The model runs on Vertex AI in your own GCP project. Every Google call is made from the browser with the employee's own token.

Applane's backend stores your company's configuration, the email addresses of the people who build, and your invoice. It never receives a Google access token, a line of app source, a prompt, or a row of your data.

Setting it up touches three places: the Google Admin console, one GCP project, and the Applane console. This site is split by who does each part.

## Pick your role

- [Google Workspace admin](https://docs.applane.dev/workspace-admins/prerequisites/): Chrome extension policy, Apps Script, accounts and groups, Drive sharing, offboarding.
- [GCP admin](https://docs.applane.dev/gcp-admins/prerequisites/): One project with billing, five APIs, one IAM grant, an Internal consent screen and a web OAuth client.
- [Applane admin](https://docs.applane.dev/console/sign-up/): Sign up, verify your domain, run the setup checker, manage seats and billing.
- [Builder](https://docs.applane.dev/builders/install-and-sign-in/): Install the extension, sign in, build and share your first app.

## For AI agents

Every page has a **Copy as Markdown** button next to its title, and is served as Markdown at the same path with a `.md` suffix (for example `/gcp-admins/oauth-client.md`). The whole site is at [/llms.txt](https://docs.applane.dev/llms.txt) (an index, one line per page) and [/llms-full.txt](https://docs.applane.dev/llms-full.txt) (every page in one file). Cache these files; re-fetch when the Last updated line or the ETag changes.
