Organize chat history, web pages, tutorials, receipts, and social media images with a fast, local workflow. Key features • Long screenshot stitching Select consecutive screenshots and automatically remove overlapping areas as they are stitched into one long image. Open any seam for precise manual adjustment when needed. • Scrolling screen capture Use the system screen broadcast to capture scrolling content and create a long screenshot. Frames are analyzed on your device and are not uploaded to a server. • Grid image splitting Split one photo into 2×2, 3×3, and other grid layouts. Adjust grid size, spacing, aspect ratio, and shapes for social media layouts and image slicing. • Photo collages Combine multiple photos into horizontal, vertical, or grid layouts. Adjust spacing, color, ratio, and crop position. • Flexible export Export as PNG, JPEG, HEIC, or PDF. Save to Photos, export to Files, or share with the system share sheet.
