Opening the studio
- From a post. Select Generate on the Attachments card under the post, or switch the editor from Post to Image. The studio opens inside the post and already knows the post’s brand, platform and words. The chat is the same one as the post’s, so ask it to switch to images and the studio starts with the prompt it wrote.
- From the Library. Select Image in the Library’s create row to start an image session on its own.
Setting up a session
A new session opens on Set up this session: Ratio, Platform, Style, Model and References. All of them are optional — “Or skip all of it and describe the image you want in the chat.”- Style offers your brand’s saved reference styles, so every image in the session follows the same look.
- Model lets you pick which image model runs, or leave it to Rheos.
Generating an image
Type into the chat: “Describe the image you want, or ask about the brand or a reference.” A switch by the chat box sets who writes the prompt:- Agent, the default — the assistant reads your post and brand and writes the prompt for you.
- Direct — your words go straight to the model, exactly as you typed them.
References
References are images for Rheos to work from. Add them from your Library or paste an image in. Each reference can carry a note saying how to use it, such as “match this lighting” or “use this product shot”. The note field reads “Add a note — sent with this reference”. A reference is used for this turn only unless you keep it: select it to keep it for the session, and it goes with every image after that. While you type, From your library suggests images you already have that might fit.Working with an image
Hover an image for its actions:- Add to post (inside a post) or Create post (from the Library) — puts the image to work. Create post starts a new post with the image already attached.
- Save to Library — keeps it for later posts.
- Edit — makes this image the one to change. Describe the change in the chat and send.
- Regenerate — same settings, new roll — runs it again with the same settings for a fresh result.
- Add to Chat — hands the image to the chat, to talk about or build on.
- Download and Delete.
Changing part of an image
Open an image and choose Edit, then Mark regions. Drag a box over an area, or select a spot to drop a pin, and say what should change there — “What should change here?”. Rheos edits only the areas you marked and leaves the rest of the image as it was. You can mark several areas in one go. In the same place, Aspect ratio re-renders the image at a different ratio.Reference styles
A reference style is an image your brand’s visuals should look like. They live on the brand’s Style tab under Reference styles, and you can pick any of them as the Style in an image session. If you gave your website when you signed up, your brand already has one: Rheos makes it from your site and logo during setup and saves it as Your website style. Add more from Add on that section:- Upload image, or pick one From Library.
- Generate in studio — opens the studio to make candidates. Each image then offers Save as reference style, which saves it to the Library and to the brand.
