About

InvisiTag

Features
Read full description

InvisiTag helps you remember things and meaningful places by saving photos and searchable clues. You do not need to remember an exact name. Search with fragments such as β€œthe pliers near the tool shelf” or β€œthe place where I watched the sunset.” InvisiTag uses names, categories, nearby clues, and place names from your records to make them easier to find with natural text or voice search. Key features β€’ Save a photo and location clues in one record β€’ Record both physical items and memorable places β€’ Search with natural text or voice β€’ Organize and filter with your own categories β€’ Pick a place on a map and open it in Apple Maps β€’ Record when you last confirmed an item or place β€’ Edit, delete, back up, and restore your records β€’ Available in Japanese and English Subscription Creating and editing records, generating searchable descriptions with AI, and advanced semantic search using meaning and partial clues are available with the InvisiTag Premium monthly subscription. Without a subscription, you can still view saved records and use standard keyword search. Eligible new subscribers can try all features free for one week. After the trial, the subscription automatically renews for US$2.99 per month in the United States App Store. Prices vary by country or region. Trial eligibility, pricing, and final terms are shown on the App Store purchase confirmation screen before purchase. You can manage or cancel the subscription at any time from your Apple Account. Photos, coordinates, and saved records remain on your device. AI features do not send photos or latitude and longitude. Only text needed for composition and search is processed through a protected backend. InvisiTag preserves clues while your memory is fresh, so you can return to them later even when only fragments remain.
