Watermark
Your name across the photo before it goes anywhere.
Text, tiled or single, with control over opacity, colour, size and position. Ten seconds, no sign-up step.
A visible mark can be cropped out. Obsydian also hides an invisible per-subscriber tag in the pixels — crop the visible one and the hidden one still names who the file went to.
Metadata Checker
That photo knows where you took it. Here’s what it says.
Drop in an image and read the EXIF it carries — device, timestamps, and the GPS coordinates most people have never checked for.
This reads what’s there. The Scrubber inside Obsydian removes it — stripped from every file you upload, automatically.
Leak Check
Find out where your content has been reposted.
A reverse-image scan of the public, indexed web — repost accounts, aggregators, dumps. A starting point for a takedown instead of a guess. (Nothing reaches inside a private group or a Telegram channel — no scanner can.)
