Superimpose X is a serious photo editor, and the editor is yours with the app — layers, masks, blend modes, brushes, effects, shadows, text and precision tools, with no subscription to use any of it. When you want more, two studios are built right in and unlock with a subscription: an AI Editor that generates and transforms images, and a true multi-track Video Editor. THE PHOTO EDITOR Build complex edits by hand with the control of a desktop app and none of the complexity. Cut out people and objects, combine images, paint masks, adjust colour, add depth and shadow, then refine every detail. • Layer-based editing with up to 24 layers • Magic Wand, Magic Lasso, brush and shape masks • 18 blend modes and 16 adjustment layers • Non-destructive layer blur and adjustments • 63 photo effects, plus clarity, colour, tone and detail controls • Text and curved text • Motion, Zoom, Spin, Lens and Selective Blur, and gradients • Warp, perspective transform and distortion • Paint, smudge, clone stamp and effect brushes • Shadow and Light Wrap tools • Camera fill with real-time masks and blend modes • Masking Library for reusable cutouts and stickers • Session Library that saves your projects automatically • PSD export with layers • Over a million royalty-free stock photos AI EDITOR Start from a photo, a sketch or a sentence and let AI do the heavy lifting, then take the result back into the layer editor to finish it properly. • Image generation from text • AI editing and inpainting • Background creation and replacement • Outpainting and image expansion • Enhance, relight and repair • Sketch to image • Headshot generation • Face swap • Image to image transformation • Image to video • AI people masking VIDEO EDITOR A real multi-track editor, not a template filler. • Edit video, images, audio and text on multiple tracks • Stack effects and animations for results that are yours • Masks for precise work, including green screen • Track objects through a shot and ramp clip speed • Animate text with elegant presets • Split, trim, rotate and freeze clips • Colour effects, blurs and distortions • Audio EQ, filters and transitions • Royalty-free photos, videos, music and GIFs • Export in a range of formats, including GIF ONE APP, ONE PROJECT The three studios share the same project. Composite a frame in the photo editor and drop it on the timeline. Generate a background with AI and mask it by hand. Pull a still out of a video and edit it as layers. Nothing is exported and re-imported just to move between them. Terms of use: https://www.superimposeapp.com/superimposex_terms_of_use.html Privacy Policy: https://www.superimposeapp.com/privacy2.html
