The SentiSight.ai mobile app enables users to make image classification and object detection predictions using images from their phones. This is an accompanying app to the SentiSight.ai image labeling and recognition web platform. On the app, users can immediately make predictions using a range of ready-to-use pre-trained models: General Classification—. Use the General Classification pre-trained model to identify the content of your image. Classification is one of the primary uses of image recognition AI General Object Detection—Using the pre-trained general object detection model allows users to identify what objects are in your image, along with the location of the object within the image. Places Classification— Use the Places Classification pre-trained model to identify the place depicted in your image. The model provides a predicted score percentage. NSFW Classification—The NSFW classification model can be used to detect whether images contain nudity or not. The model provides a prediction of whether the image is safe or unsafe, by way of a predicted score percentage. Optical Character Recognition—The optical character recognition (OCR) pre-trained model can be used to detect and identify text within your image, and is supported for a wide variety of languages. Pose Estimation—The pose estimation model can be used to detect the poses of people in the image. It detects 15 joints and key points of the human body. Image Similarity Search—an image similarity search model is used to find visually similar images to one that is uploaded. The retrieved images are sorted by their similarity score. With the SentiSight.ai mobile app, users can also make predictions using the custom models that have been trained using the SentiSight.ai web interface. The app uses the same login credentials as the web version of SentiSight.ai. The app does not currently support the training of new models itself, but the mobile app can be used to upload images to your projects that can be later used for training custom models. The SentiSight.ai mobile app and web platform are developed by Neurotechnology. Neurotechnology is a developer of high-precision algorithms and software based on deep neural networks and other AI-related technologies.

Private Docs Vault is a local encrypted vault with no backdoor. Add photos, videos, PDFs or any file and it is encrypted immediately with AES-256-GCM. It opens only after Face ID / Touch ID plus the 6-digit vault PIN you choose. Fully offline No server, no uploads, no analytics, no ads or trackers. The only network use is App Store purchase verification, handled by iOS. Real encryption, not just hiding Every file is encrypted in chunks; file names and the index are encrypted too. The file key is protected by your recovery key plus your vault PIN together; the recovery key lives in the iOS Keychain and is released only by Face ID / Touch ID, never by the device passcode. Five wrong PINs in a row destroy everything. What you get • Add from Files or Photos; originals are never modified • Live Photos stay Live Photos: touch and hold to play, and save back to Photos with the motion • Built-in camera: photos and videos encrypted directly, never touching the photo library • Video streams while decrypting, PDF text search, Markdown reader • Folders, search, sorting, favorites and recents • Multiple vaults: different PINs open different vaults, and the app never reveals how many exist • Auto-lock delay, automatic blackout during screen recording and mirroring • Password-protected AES zips that open in 7-Zip and friends • Encrypted backups to Files or iCloud Drive • Share area (for your Mac): a clearly labelled UNENCRYPTED folder you drag files in and out of with Finder over a cable • Password list: encrypted, one-tap copy • Notes, PDF merge and split, duplicates • iPad split-view layout The free plan stores up to 50 files or 1 GB, whichever comes first. “No Storage Limit” is the only paid item: a one-time purchase that is yours forever. It removes the cap (files stay on your device, so free space is the real limit) and includes password zips, batch export, encrypted backups, the password list, PDF merge and split, and the Share area. No subscription, no auto-renewal; restore it for free on other devices with the same Apple Account. Optional “Support the developer” tips can be bought any number of times. They are just a thank-you and unlock nothing. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Important Setup gives you a recovery key. After switching phones, restoring a backup, changing Face ID or turning off the device passcode, that key plus your vault PIN brings the vault back. Forgetting your PIN, or losing both the recovery key and the phone, makes the content unrecoverable. That is by design: there is no backdoor. Make encrypted backups regularly.
