Chromis is a photo editor whose AI runs on your phone. Cut a subject out of a photo, erase something you did not want in the shot, stack layers, build a collage, and export it. Your photos are not uploaded anywhere.
AI THAT RUNS ON YOUR PHONE
• One tap removes the background and leaves your subject on transparency. Pick between two models: Android's built in segmentation, or an open source U2-Net bundled inside the app.
• Tap an object you want gone and it is cut out of the photo.
• Refine the result: auto clean up stray specks, soften the cut edge, or fix it by hand with an erase and restore brush.
• The U2-Net model ships inside the app, so cut-outs still work with no connection.
LAYERS
• Stack photos, captions and speech bubbles on one canvas.
• Drag to move, pinch to scale and rotate.
• Reorder by dragging, hide, duplicate, rename or delete from the Layers panel.
• 16 blend modes, from Multiply to Luminosity.
• Drop shadow and outline on any layer. On a cut out subject both follow its silhouette rather than a rectangle.
• Set any layer's opacity.
• Merge two layers, or flatten the whole stack into one photo.
COLOUR AND LIGHT
• 14 one tap looks: Vivid, Punch, Chrome, Warm, Cool, Sunset, Dawn, Dusk, Fade, Matte, Retro, Sepia, Mono and Noir, each with a strength slider.
• Brightness, contrast and saturation from 0 to 200 percent, and hue across the full circle.
• HDR that lifts shadows and brings out local detail.
• Vignette with its own size, softness and colour.
• Nothing is baked in. Your original file is never modified, and every value can be moved back.
TEXT AND COMIC BUBBLES
• Captions in five display fonts, or import your own .ttf or .otf file.
• Set size and colour, and give the text an outline with its own thickness and colour.
• Five bubble shapes: Speech, Thought, Shout, Caption and Whisper. Drag the tail to aim it at whoever is talking.
PHOTO GRID COLLAGES
• 2 to 5 photos across 18 layouts.
• Drag a divider and it trades space between exactly those two cells.
• Border up to 80 px, rounded corners up to 60 px, nine frame colours.
• Every tool works inside a cell, so you can cut out a subject in one photo of a collage.
• Shuffle the photos between cells, or drag one onto another to swap them.
PROJECTS
• Bring photos in from your gallery, your camera, or the clipboard.
• Every edit saves itself. Close the app and carry on later.
• Home keeps your recent projects with live previews. Search them by name, rename, duplicate or delete.
CANVAS AND EXPORT
• Start from a photo at its own size, from a preset such as square, portrait or story, or from a size you type.
• Crop freehand, or to 1:1, 4:5, 9:16, 16:9, 3:2 or 2:3.
• Export PNG, JPG or WebP at 100, 75, 50 or 25 percent of the canvas.
• PNG and WebP keep transparency. Save to your gallery or send straight to another app.
• Undo and redo anything. Projects save themselves while you work.
FREE, WITH ONE OPTIONAL PURCHASE
Every tool is free to use. Ads pay for it: one banner on the home screen, a short rewarded ad before an export, and one rewarded ad per editing session to unlock the AI tools. No full screen ad ever interrupts you on its own.
One optional purchase removes every ad and every ad prompt for good. It unlocks nothing else, because nothing else is locked.
PRIVACY
• The app asks for one permission: internet, used for ads and purchases.
• No camera, storage or location access. Photos arrive through the Android photo picker, which hands over only the picture you chose.
• No account and no sign in.
• Nothing you edit leaves the device unless you share or export it yourself.
Runs on Android 8.0 and newer, on phones and tablets, in portrait and landscape.
