TruthLens helps you inspect whether an image carries AI provenance, Content Credentials, EXIF metadata, XMP data, software tags, or suspicious file-structure signals. Designed for privacy-first image verification, TruthLens analyzes JPEG and PNG files locally on your device. Your image is not uploaded to a server. TruthLens prioritizes provenance-based evidence such as C2PA metadata and known AI tool signals from providers including OpenAI and other image-generation pipelines. It also checks camera metadata, software markers, file structure, and metadata sparsity to produce a clear, easy-to-understand result. Key features: β€’ Local image analysis β€’ C2PA and Content Credentials inspection β€’ EXIF, XMP, PNG, and JPEG metadata checks β€’ AI provenance signal detection β€’ Clear verdict, confidence score, and evidence list β€’ Exportable detection report TruthLens provides heuristic provenance assessment, not forensic or legal certification.

Minimalist calendar-based notes and journaling app. Guiding principles: # Simplicity You pick a day on the calendar and add a note to that day. Basic usage is as simple as that. No clutter, no distractions, no ads. # Reliability Your notes are stored as plain markdown files in iCloud or on your own device. Edit them with your preferred apps, copy or sync them wherever you want, and keep access and control regardless of Gregor itself. # Polish Access information easily, edit markdown from a native UI, and use local AI features to easily search and summarize your notes.
