Generate, edit, or analyze images with Lumo AI

With Lumo AI, you can upload an image for analysis, generate images from a description, edit an existing image file, or turn a rough sketch into a finished visual, simply by telling Lumo what you need. Lumo can work with text, images, and uploaded files in the same conversation.

Like your conversations, all images and uploaded files in Lumo are protected by zero-access encryption. No one else, not even Proton, can access them.

This feature is available to all Lumo users, on both web and mobile apps.

In this article, we explain how to:

• Generate an image
• Upload an image or file
• Edit an image
• Analyze an image or file
• Turn a sketch into a finished image
• Access an image you previously uploaded or created

Generate an image

There are three ways to create images in Lumo:

A. Simply type your image prompt in the chat window.

B. Select Tools under the chat window, then select Create image.

This option also lets you select image dimensions in the bottom-right corner of the chat window.

Enter your prompt, and Lumo will create your image.

C. Within the menu bar, select Images.

This will open your image gallery, which stores images from past conversations and auto-generated ones for inspiration.

Upload an image or file

1. Go to lumo.proton.me(neues Fenster) or open the Lumo mobile app, and sign in to your Proton Account.
2. Select the + icon under the chat window. Select Upload from device.
3. Choose the image or file you want to upload to Lumo. It will be automatically uploaded to your chat window.

Edit an image

Once you’ve generated or uploaded an image, describe the edits you want Lumo to make. Lumo will apply your edits and return the updated image in the same conversation.

If you have your generated image already open in the conversation, you can also select Modify in the bottom-left corner of the image, then select or describe the changes you want to make.

Analyze an image or file

1. Start by uploading your file or image.
2. Describe how you want Lumo to analyze it in the chat window.

For example, you can ask Lumo to suggest dinner dishes based on a photo of what you have in your fridge, or get it to summarize a legal contract.

Turn a sketch into a finished image

1. First, upload your sketch to Lumo.
2. Ask Lumo to create an image based on your sketch. For best results, add context or specific descriptions such as “Make the background purple” or “Use a watercolor style”.

Lumo will return a finished image in the same conversation.

Access an image you previously uploaded or created

1. Go to lumo.proton.me(neues Fenster) or open the Lumo mobile app, and sign in to your Proton Account.
2. Open the menu bar and select Images.

This will open your image gallery, which stores uploaded images, previously created images, and auto-generated images for inspiration.
