Calcish

Calcish is a macOS calculator and notebook from Coding Robots; the linked US App Store listing identifies the seller as Koding Robots doo. It combines editable code cells, mathematical results and AI conversations in saved codebooks or a floating scratchpad opened through a global hotkey. Its QuickJS-based runtime adds big-number, fraction, vector, matrix and decimal operations. This makes it a candidate for exploratory calculations and small data-manipulation tasks when a plain calculator or browser console is awkward. The notebook supports rearranging and rerunning cells, and exports to Markdown, JavaScript or PDF. Runtime differences matter when moving existing code: Calcish resolves pending asynchronous jobs synchronously and does not provide browser-style timers. Treat it as a specialized calculation environment rather than assume arbitrary Node.js or browser code will run unchanged. AI cells can use downloaded local models or remote providers configured with an API key. Local models require sufficient memory and may run slowly on some machines; remote requests use the selected provider's service and billing. The homepage and documentation list different model versions, so check the installed app's current choices instead of relying on a fixed model list. The US App Store currently lists a USD 9.99 download and an optional Calcish Pro in-app purchase of USD 49.99; the description identifies Pro as an automatically renewing yearly subscription. It requires macOS 13.0 or later. Confirm the device's regional offer and included features before purchase. This review inspected official pages and the public store listing without installing the app or running calculations. Developer privacy statements about local app data should not be extended to inputs sent to remote AI providers. Choose the processing route appropriate to the material in the notebook.
