# Welcome to Segmentit

Everything you need to turn a photo into your next creation.

[My first project](https://segmentit.com/docs/first-project/) [Open the studio](https://segmentit.com/app?lang=en)

## Your first object, step by step

Open the studio, create a project and upload a photo. Choose the subject you want to keep, refine its outline and start creating in 3D.

## Three views, one project

Photo is where you choose your subject. Selection shows the isolated object and lets you refine the cutout. 3D is where you explore and download your generated model.

Your project keeps your source image, selections and generated assets together. Return to it whenever you want to continue.

## Choose your next step

Start with the first-project guide, learn how to select several objects, or explore the export guide when your creation is ready. The search above looks through all guides in this documentation.
