Version 0.4.0
Released Jul 18, 2026 - 22.53 KBWorks with firefox 109.0 and laterNew in 0.4.0
Annotate changes right on the page. Press N on any element and type the change you want ("reduce width to 320", "match the header font"). Mark up as many elements as you need, then press Cmd+C once — each element is copied paired with your instruction, so your AI gets a complete work order with nothing left to explain.
Cleaner, cheaper copy. The copied CSS is now de-noised — default and redundant properties are dropped and longhands collapse into shorthands — so you send fewer tokens with no loss of meaning.Source code released under MIT License
