    I first posted Splice CAD as an in-browser tool for making cable harnesses. Since then it’s grown in both features and scope — the direction is moving from “harness-only” toward a lightweight CAD for wiring and electrical assemblies. New functionality includes: Editing Enhancements - Full undo/redo to easily restore editor state - Multi-select & group actions to move, delete, and add components - Bulk connect tool to create straight-through, crossover, or custom wiring patterns quickly - Multiple connections per pin allow for daisy chains, etc. Documentation Additions - Multi-page PDF…

    Hi HN, I'm Zach, one of the co-founders of Adam (https://adam.new). We've been on HN twice before with text-to-CAD/3D experiments [1][2]. The honest takeaway from those threads: prompt-to-3D model web apps are fun, but serious mechanical engineers don't want a black box that spits out an STL. They want help inside the CAD tool they already use, with full visibility and control over the feature tree. So we built that. Adam is now a harness that integrates directly with your CAD. It reads your parts, understands the existing feature tree, and edits it for you agentically. We are…

    Hey HN, We got tired of browser frameworks restricting the LLM, so we removed the framework and gave the LLM maximum freedom to do whatever it's trained on. We gave the harness the ability to self correct and add new tools if the LLM wants (is pre-trained on) that. Our Browser Use library is tens of thousands of lines of deterministic heuristics wrapping Chrome (CDP websocket). Element extractors, click helpers, target managemenet (SUPER painful), watchdogs (crash handling, file downloads, alerts), cross origin iframes (if you want to click on an element you have to switch the target first,…
