   Plandex – an AI coding engine for complex tasks▲304

   Hey HN, I'm building Plandex (https://plandex.ai), an open source, terminal-based AI coding engine for complex tasks. I built Plandex because I was tired of copying and pasting code back and forth between ChatGPT and my projects. It can complete tasks that span multiple files and require many steps. It uses the OpenAI API with your API key (support for other models, including Claude, Gemini, and open source models is on the roadmap).

    Revise – An AI Editor for Documents▲85

    I started building this 10 months ago, largely using agentic coding tools. I've stayed very involved in the code base and architecture, and have never moved faster in my life as a dev. The word processor engine and rendering layer are all built from scratch - the only 3rd party library I used was the excellent Y.js for the CRDT stack. Would love some feedback!
