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...

Ask Claude Code for a change like one it made last week and it reads the same files again, falls into the same test traps again, and you pay for all of it again.Singularity learns from your finished sessions (change committed, tests passing): where each kind of change goes in this repo, how it gets checked, and the mistakes made along the way. When the next task starts, a hook hands the agent the workflows that fit, pointed at the code as it is today. Picking them is plain text matching with no model call. It stores where to edit, never the code its...
