Sinew is a desktop AI coding application that gives you complete control over how an AI assistant helps you code. Unlike fixed AI tools, Sinew lets you customize which abilities the AI has, reword its instructions, and even toggle features on and off. You can work with a single AI assistant or launch a team of multiple AI agents that coordinate together on complex projects. The app includes a built-in code editor and terminal, connects to various AI providers (Anthropic, OpenAI, Google, and others), and supports Model Context Protocol extensions. It's designed for developers who want an AI coding partner that adapts to their workflow rather than forcing them into a rigid approach.
How It Works
You grab the installer from the releases page and install Sinew on your computer, just like any other app.
You launch Sinew and point it to the folder where your code lives. The app shows you a file tree and a code editor, ready to go.
You sign in to your preferred AI provider—Anthropic, OpenAI, Google, or others—using your existing account. Everything stays connected to your own subscription.
You type a question or describe what you want to build. The AI reads your files, runs commands, searches your code, and makes changes—all inside the app.
One AI assistant handles everything, like pair programming with a smart colleague.
Multiple AI agents each take different roles—architect, builder, tester—and share progress on a task board.
You open settings and customize which tools the AI can use. You can reword descriptions, turn features on or off, and decide exactly what the AI sees and does.
Files get written, tests run, ideas get explored. You have a powerful coding partner that does exactly what you need—no more, no less.
