## Overview
AskUI is an agentic test automation platform that uses computer-use agents to automate testing across desktop, web, mobile, and embedded HMI interfaces. Instead of relying on DOM queries or fragile UI selectors, agents observe the screen visually and reason about actions to perform, making it capable of testing interfaces that traditional tools cannot reach. The platform is designed for QA engineers, developers, and engineering leaders who need reliable automation on real infrastructure. One limitation is that LLM-based results may vary, though the platform implements caching and structured prompts to maintain consistency.
## Key Features
- Computer-use agent that sees, reasons, and acts on any screen
- Plain English test authoring with no selectors or brittle scripts
- Support for multiple platforms: macOS, Windows, Linux, Android, iOS, embedded HMI
- Flexible model routing - Claude, Gemini, OpenAI, or custom providers
- Intelligent caching that reduces LLM costs by skipping redundant calls
- Host Mode for full OS access and Companion Mode for devices without software access
- On-premises and air-gapped deployment options
- ISO 27001 certification and GDPR compliance
- Live run streaming with audit-ready HTML reports
- Versioned system prompts and tool allowlists

## Use Cases
- Automated testing for legacy systems without accessible APIs or UI objects
- POS device and infotainment system testing across complex workflows
- Industrial software and hospital system testing without breaking on state changes
- CI/CD pipeline automation for Android and desktop application release validation
- Regression testing for mobile and business applications with fragile UI identification

## Who It Is For
- QA engineers testing complex interfaces
- Developers automating system testing
- Engineering leaders managing production automation infrastructure
- Teams working with legacy systems lacking accessible APIs
- Organizations requiring on-premises deployment and compliance

## Pros
- Works on any interface where state lives on the screen (desktop, web, mobile, embedded HMI) - tools like Selenium struggle with this
- Intelligent caching mechanism that dramatically reduces LLM costs while maintaining audit trails
- Production-ready with on-prem deployment, ISO 27001 certification, and comprehensive compliance features
- No lock-in to specific models - supports Claude, Gemini, OpenAI, and custom providers through bring-your-own-model

## Cons
- LLM-based execution may have variable results across runs compared to traditional deterministic automation
- Requires device pairing or HDMI capture setup which adds infrastructure complexity
- Primarily focused on test automation rather than broader RPA use cases
