About

Sunday on Earth

Read full description

Sunday on Earth is your private archive for art visits. Free to download, with no ads or subscription. Core archive features remain free. Each new account includes 20 optional AI artwork recognitions, followed by one-time purchases of permanent recognition credits when needed. Turn artwork and wall-label photos into a searchable personal collection: • Choose photos from your library or take them in the museum • Use optional AI artwork recognition • Scan wall-label text on your device • Suggest a city and nearby museum from photo date and location • Review and edit the artist, title, date, medium, exhibition and venue before saving • Browse works and exhibitions, then filter by location, museum and information status • Revisit your journeys on a personal art map • Export artwork cards made for saving and sharing Privacy first: before AI recognition, the app re-encodes the selected photo and removes EXIF and GPS. Raw photo location is never sent to AI. Manual entry and on-device label scanning remain available without uploading a photo to AI. AI results can be inaccurate, so review them before saving. Sunday on Earth is for users aged 18 or older. AI is available only in Google Gemini-supported regions.
