Everyday Utilities
Rapidool replaces your browser tabs with native tools that keep your data private and process text instantly.
Instead of opening a slow web tool, prepend a block of text with @ to transform it into a dedicated environment.
@code / @html@diff@regex@GET / Mock APIsDevelopers constantly evaluate timestamps and quick math. The gutter actively scans your text to evaluate equations, epoch timestamps, dates, and Base64 strings, rendering the results instantly without an external calculator.
Selecting text opens dedicated popover tools. Pick a color to see its hex/RGB/HSL values, select a date to open a calendar view, or inspect a JWT's decoded payload safely on your machine.
Format JSON instantly without pasting your payload into a random ad-supported formatter website. Press Cmd+Shift+Space anywhere in macOS to drop down the Rapidool Bar and run generators like /uuid or JSON formatters on your clipboard.
No web latency. No cloud account requirements. Just a native, local-first workspace for raw text, formatting, and computational tools.
Paste a raw JSON payload from your API. Instantly decode any JWT tokens using the Inspector, auto-format the JSON with a quick Command Bar action, and write a quick @code JS block to extract specific fields—all without leaving the editor or opening a browser tab.
Drafting a UI component? Drop your HTML and CSS into an @html section and preview it immediately in the side panel. Spot a color you want to change? Click the hex code to open the Color Inspector, visually pick a new hue, and copy its HSL value.
Testing a mobile app's fetch logic but the backend isn't ready? Paste your desired JSON response, prepend it with @GET /api/users, and Rapidool instantly spins up a local server on port 9090 serving that data. No deployment required.
Need to generate boilerplate or transform unstructured data? Type /gen to stream AI code writing directly into your active scratchpad character-by-character. Powered by your local Ollama instance, meaning your proprietary code and API keys never leave your machine.

It's also much faster than opening a browser tab, finding a site, and dealing with ads or latency.
Yes. Rapidool replaces dozens of single-purpose websites for JSON formatting, JWT decoding, Base64 encoding, epoch time conversion, and regex testing by bringing them all into one native macOS app.
No. Rapidool is designed local-first. Text scanning, math evaluation, JS runtimes, formatting, and mock HTTP routing run 100% on your local macOS machine. No server syncing or telemetry is used (unless you point it to a remote Ollama server for AI prompts).
Yes. You can define mock endpoints using supported HTTP methods and custom route paths (e.g., @GET /api/v1/users) directly inside your document. Rapidool serves these endpoints locally on port 9090, meaning your active web browser, curl command, or mobile client can query them instantly without spinning up a real backend.
Yes. By creating an @regex section, you can test regular expressions with real-time match highlighting against your sample text directly in the editor.
Yes. Rapidool scans the ~/.rapidool/scripts folder for JS files. Any script added there automatically behaves as a command in the Command Bar (e.g. /myCustomFormatter), transforming document text and returning output directly inline.
Rapidool integrates exclusively with Ollama as the AI provider. You can point it to your local Ollama instance (or a custom Ollama endpoint) to run models like Llama, Mistral, or Gemma. Since Ollama runs models locally on your machine, your code prompts and text data remain 100% private and never leave your device.
Rapidool is available on the macOS App Store with a 7-day free trial. After the trial, you can choose between a monthly subscription or a lifetime purchase option. It requires macOS 13 or later.
