AI Subroutines – Run automation scripts inside your browser tab
Web AppWe built AI Subroutines in rtrvr.ai. Record a browser task once, save it as a callable tool, replay it at: zero token cost, zero LLM inference delay, and zero mistakes.The subroutine itself is a deterministic script composed of discovered network calls hitting the site's backend as well as page
Capabilities4 decomposed
browser-based automation script execution
Medium confidenceThis capability allows users to run automation scripts directly within their browser tab, leveraging the browser's JavaScript engine to execute tasks without needing external tools. It uses a lightweight scripting framework that integrates with the DOM, enabling real-time interaction with web elements and asynchronous operations. The design choice to operate entirely within the browser context minimizes latency and enhances user experience by avoiding server round trips.
Utilizes the browser's native JavaScript execution environment for immediate script execution, avoiding the need for server-side processing.
More efficient than traditional automation tools as it executes scripts directly in the browser without network latency.
dynamic dom manipulation
Medium confidenceThis capability enables users to programmatically alter the Document Object Model (DOM) of the web page in real-time. By providing a set of APIs for selecting, modifying, and removing elements, it allows for dynamic content updates and user interface changes based on script logic. This is achieved through direct interaction with the browser's JavaScript APIs, making it distinct from tools that require page reloads or external libraries.
Offers a straightforward API for DOM manipulation that integrates seamlessly with existing web technologies without additional libraries.
Faster and more intuitive than jQuery or similar libraries for simple tasks due to direct access to native APIs.
event-driven automation triggers
Medium confidenceThis capability allows users to define automation scripts that respond to specific events occurring on the web page, such as clicks, form submissions, or page loads. By leveraging the browser's event listener model, scripts can be executed conditionally based on user interactions or changes in the DOM. This approach enables a reactive automation model that enhances interactivity and user engagement.
Utilizes the native event listener capabilities of the browser to create responsive automation scripts without additional overhead.
More efficient than traditional polling methods, as it only executes scripts in response to actual events.
script sharing and collaboration
Medium confidenceThis capability allows users to share their automation scripts with others through a simple URL or a collaborative interface. It employs a version control system to track changes and facilitate collaborative editing, ensuring that multiple users can work on scripts simultaneously. This is achieved through a cloud-based storage solution that synchronizes changes in real-time, making it easy to manage script versions and contributions.
Incorporates real-time collaborative editing features similar to Google Docs, tailored specifically for automation scripts.
More user-friendly than traditional version control systems for non-developers, as it simplifies the sharing process.
