Visio.AI Gallery finds any photo by what's in it, and everything happens on your phone. SEARCH BY MEANING Describe a photo in a sentence, like “a cup of coffee on a table” or “sunset over the sea”, and Visio finds it, even when it never labeled it. Or type a word: Visio recognizes more than 400 things, knows where your photos were taken, the trips it found for you and the people you have named. The model runs on your phone. YOUR PHOTOS NEVER LEAVE YOUR PHONE Every photo is analyzed by a model that runs on the device. Nothing is uploaded, no account is needed, and you can take photo access back at any time. Lock the app with your face or fingerprint. TRIPS, FOUND FOR YOU From where and when your photos were taken, Visio spots your trips, names them after the cities ("Rome & Florence") and shows the days, cities and photos, with the route drawn on a map. Rename a trip, save it as an album, or tell Visio it was not a trip. SEE WHERE YOU TOOK THEM Every photo with a location, on one map, grouped by place. Pan the map and the list of places in view follows, each with how many photos it holds. PEOPLE, ON YOUR PHONE Visio groups the faces in your photos and you give the names. It recognizes no one. People is off until you turn it on, faces never leave the phone, and one switch deletes all of it. MEMORIES What you shot on this day in earlier years, and the trips you took, right above your photos. COLLAGES AND SLIDESHOWS Put up to nine photos in one frame: pick a layout, a ratio for your feed or story, the corners and a colour. The collage is saved in full resolution, in its own album. Or play any album, trip or person as a slideshow, with slow Ken Burns motion and music. DUPLICATES OUT, GIGABYTES BACK Similar Photos finds bursts and copies, tells you how much space you would get back and keeps the best copy with one tap. Image Compress shrinks photos to about a third of their size, keeps the EXIF data and shows exactly what you saved. Originals can go to Trash, where they wait for you. Blurry Photos finds the shots that came out of focus, blurriest first, and Large Videos lists every video over 100 MB. A REAL EDITOR Crop, straighten, rotate and flip. Tune brightness, contrast, saturation, exposure, hue, temperature, sharpness and more. Filters, paint and text. Every edit is saved as a new copy, so the original never changes. PHOTOS AND VIDEOS IN ONE VIEWER Swipe between photos and videos, pinch to zoom, drag down to close. Videos play right in the viewer, in portrait or landscape, with scrubbing, playback speed and mute. A GALLERY THAT KEEPS UP Pinch the grid to move between day, month and year. New shots appear on their own. Albums fill themselves: Screenshots, Documents, Selfies, Food, Pets, Nature, Celebrations and Vehicles. Stats show what Visio found, year by year and place by place. Trash keeps deleted photos for 30 days, and every action can be undone. Archive takes the photos you would rather not scroll past out of the grid, search and the map. ALSO Favorites, batch select and share, details with camera, lens and location, dark and light theme, and 12 languages: English, Turkish, Spanish, German, French, Italian, Portuguese, Russian, Hindi, Japanese, Simplified and Traditional Chinese. Visio.AI Gallery is a one-time purchase. No subscription, no ads, no account.
