If RPAs are holding you back, let's talk.Book a DemoOr just email us at connect@minicor.comFrequently Asked QuestionsWhat is Minicor?Minicor is a platform for building and running desktop automations at scale with computer use agents. AI companies selling into healthcare, automotive, logistics, and financial services need to read and write to their customers' systems of record. These are old desktop applications with no APIs. Minicor automates them reliably so companies can go live in weeks.Why can't I just use the system's API?Most legacy desktop systems like EHRs, ERPs, DMS, and PMS have no writable API and never will. Some vendors are actively restricting third-party API access. The only way to read or write data is to interact with the desktop like a human would. That is the problem Minicor solves.Why not build RPA in-house?Building one RPA is not hard. Running hundreds reliably is. UIs change, edge cases pile up, errors cascade. At scale, even small error rates become catastrophic. Engineering teams end up spending all their time maintaining automations instead of building their core product.How is Minicor different from traditional RPA or computer use models?Traditional RPA vendors use brittle scripts that break when UIs change. Computer use models work for demos but fall apart in production at 80-85% accuracy because they figure everything out from scratch every time. Minicor stores automation as deterministic code and uses the agent only for recovery and edge cases. Faster and more accurate in production.What happens when the UI changes?Minicor self-heals. A reflection agent verifies every action against what is on screen and self-corrects before mistakes cascade. When a vendor ships a UI update, the automation adapts instead of crashing. 93-96% click accuracy vs 80-85% for other approaches.How long does it take to go live?Zero to production in weeks. Install our Desktop Client, record a video of a human performing the workflow, and we handle everything after that. Traditional RPA and integration approaches typically take 4 or more months.Is Minicor HIPAA compliant?Yes. SOC 2 Type II certified and HIPAA compliant. For on-premise deployments, the entire platform is containerized and runs inside your network. No data leaves your perimeter.What systems does Minicor work with?Any legacy desktop or web application. Healthcare EMRs like Athena, Epic, Cerner, and PS Suite. Dental PMS like Open Dental and Dental Vision. Automotive DMS like CDK Global. Supply chain systems like SAP and HighJump. Home health systems like Wellsky and Home Care HomeBase.

Minicor is a platform designed for building and running scalable desktop automations utilizing computer use agents, primarily targeting organizations that need to interact with legacy systems that lack modern Application Programming Interfaces. This approach addresses the fundamental challenge that many enterprise systems, such as Electronic Health Records or Enterprise Resource Planning systems, do not offer writable APIs, necessitating interaction with the underlying desktop application as a human would. Minicor solves this by reliably automating these interactions, enabling organizations to transition workflows from manual desktop operation to automated execution in a short timeframe.

A core innovation of the platform is its capability to handle dynamic changes through self-healing agents. When user interface elements shift or unexpected dialogs appear, the agent is designed to catch these shifts, verify every action against the current screen state, and self-correct before a workflow breaks. This self-healing mechanism eliminates the need for constant script rebuilding whenever vendors update user interfaces, significantly reducing maintenance overhead, which is often the primary impediment in traditional Robotic Process Automation. This adaptation results in markedly higher accuracy, achieving click accuracy rates of ninety-three to ninety-six percent, substantially outperforming traditional methods that often yield eighty to eighty-five percent accuracy.

The platform operates on a distributed, scalable architecture. Computer use agents execute on Windows Virtual Machines or within web browsers, allowing deployment across on-premise infrastructure, the cloud, or Citrix environments. Execution is triggered via a single Application Programming Interface call, demonstrating high scalability, with the system capable of running at levels such as twenty-five thousand patient orders per day in a production setting. The internal operation involves the AI system initiating a request to Minicor, which connects the necessary Virtual Machines, routes the execution, and manages the workflow visually. The process leverages an API call to execute a full desktop workflow, which results in a structured JSON response detailing the status, actions performed, verification results, and execution duration.

Minicor incorporates built-in observability features to enhance debugging and monitoring. It allows users to replay full video recordings of every automation run and provides direct failure notifications through channels like Slack. Debugging is facilitated by providing execution context, including screenshots and detailed execution logs, enabling teams to debug with context rather than guesswork. The platform features a visual workflow editor where users can define multi-step processes, such as opening an application, navigating to specific screens, filling out form fields, and verifying the submission. Execution history is maintained, allowing review of previous runs, such as monitoring the status of multiple past executions.

From an architectural perspective, the system is designed to handle complex data exchange efficiently. The system allows an AI system to send a single request containing the workflow ID and necessary data, which the Desktop Service routes to the appropriate VM for agent navigation and data interaction. This streamlined process bypasses the need for external Software Development Kits or browser extensions for control. Furthermore, the entire platform maintains high security and compliance standards, being certified for SOC 2 Type II and HIPAA compliance. For on-premise deployments, the entire platform is containerized and operates strictly within the organization's network perimeter, ensuring that sensitive data does not leave the security boundary.

The platform is applicable across a wide spectrum of industries and systems. Minicor supports any legacy desktop or web application, including complex healthcare systems like Epic and Cerner, dental practices systems such as Open Dental, automotive systems like CDK Global, supply chain platforms like SAP, and financial services applications. By automating interactions with these diverse systems, organizations can achieve rapid deployment, often moving from zero to production in weeks, contrasted with traditional integration approaches that commonly require four or more months.
