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.

It records a narrated walkthrough of your real app on your own machine, and the finished video opens in your browser, ready for your help center or docs, where anyone edits the narration, voices, and 79 languages. Engineers can keep the videos in the repository as Playwright tests that CI re-records on every release. Hi HN, I'm Olli. My friend Patrik and I are bootstrapping ScreenCI: tutorial videos of your web app that you can re-record in your CI on every release. If the video is out of date, the run fails like any E2E test.I've been on teams where the tutorial videos were outdated, or even where we held back UI improvements due to manually maintained videos. That's why we built system where you can describe the videos as Playwright E2E test code. Coding agents are very good with writing tests and you can run these scripts against your app on your machine. ScreenCI converts them into narra...
