Etchv vs LLM Fuzz CI

Add an invisible watermark to images, PDFs and video, then detect it to see which copy was shared. Forensic watermarking API with a free trial. Hello HN!The inspiration for Etchv came directly from friends who raised concerns about the growing ease of unauthorized media copying without attribution. To address this, Etchv embeds an invisible watermark inside images, PDFs, or short videos that survives modifications like screenshots, format changes, and file compression.You can try it on our homepage without signing up. There's also a live demo where a watermarked PDF page gets screenshotted and the watermark ID is still successfully recovered: https://etchv.com/demo/traceInstead of training a model from scratch...

A GitHub Action that lets a coding agent write adversarial inputs for your tests, and reports only the ones that fail. Hi HN!Most of the explanation is in the blog post, and the code lives there: https://github.com/tiime-software/llm-fuzz-ci/Happy to receive feedback, and to know how other people use agents to improve code security!
