Postra Mobile

AI understands your library. Search in your own words, no tagging. Rate, pick, arrange, retouch and export in one flow. Ratios for Instagram, X, Threads 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, lens, and color

Build photo collages • Grid, Free, and many Design templates for flexible layouts • Presets for Instagram, X, Threads, Stories, and note 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

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.
