AI understands your library, search it in your own words. Pick, arrange, retouch, export in one flow. Play adds film and analog looks in a tap. For Instagram, X and more.
Postra turns your camera roll into a single flow: find, compose, refine, and export. No tagging required — just open your photo library and let on-device AI understand your photos.
Find the one shot
• Recent, Random, or AI search to surface buried photos fast
• Search by words like "flower" or "sky" with on-device AI text search
• Tap any photo to gather visually similar ones
• Filter freely by camera and lens
Build photo collages
• Grid, Free, and many Design templates for flexible layouts
• Build several boards at once and export them together — great for finishing a tall composite as a multi-image post
• Presets for Instagram, X, Threads, Stories, TikTok, YouTube, and Pinterest aspect ratios
• "Preview" — see exactly how your post will look before sharing
Refine
• One-tap color presets, plus brightness, HSL, curves, and crop
• Copy & paste adjustments to other photos
Play — film and analog textures
• Over 60 effects: film grain, halation, light leaks, double exposure, film scratches, mold, and more
• Nearly 40 looks (presets) applied in a tap from a thumbnail sheet, from film-stock styles to cinematic grades
• Fine-tune the strength of each effect in the detail settings
Finish and export
• Add a caption band with EXIF (camera, lens, aperture, date)
• Print-style finishing with paper texture and drop shadow
• High-quality export at each platform's aspect ratio, ready to share
Privacy first
• All analysis, layout, and export happen entirely on your device
• Your original photos are never modified
• No account, no tracking, no ads
Note: AI text search downloads a search model (~146MB) once on first use. Your photos are never uploaded.
For iPhone and iPad.
