Calcish is a versatile tool designed for macOS that combines the features of a calculator, JavaScript code runner, and AI chat interface. With its user-friendly notebook interface, users can perform visual calculations, execute JavaScript code, and engage in conversations with local or remote AI effortlessly.

The strength of Calcish lies in its convenience and efficiency. It offers a more seamless experience compared to using a browser console or Node REPL for quick tasks, exploratory programming, and data manipulation. The tool provides better visual representation of results, allows for quick code editing and execution, and offers a wide range of useful functions.

Based on QuickJS, Calcish enhances JavaScript with advanced features to enhance productivity. Math mode enables precise calculations with large numbers, fractions mode enables calculations with fractions, and vectors & matrices mode allows for vector and matrix operations. Additionally, Calcish supports decimal number type and literals for accurate currency calculations.

Getting started with Calcish is straightforward, even for beginners in programming or JavaScript. The tool comes with comprehensive documentation, eliminating the need for complex configurations. Users can start by using Calcish as a calculator and gradually explore its various functions.

Calcish is accessible from anywhere on your macOS device. Simply use a global hotkey or click on the menu bar icon to open the scratchpad, which floats above other applications. Users have the option to save their work as a codebook for future reference or clear it when finished.

In addition, Calcish offers the option to interact with private local or remote AI. It provides access to large language models, allowing users to chat with state-of-the-art AI models while maintaining privacy. Users can also communicate with AI models from OpenAI, such as GPT-4 and GPT-3.5, Cohere, and TextSynth via API integration. The tool also allows for experimentation with custom prompting and the creation of user-defined functions that leverage AI capabilities.
