Automate your desktop

Engine
3-Tier Pipeline

Your desktop stays yours.

Other automation tools hijack your screen. Sentinel runs on its own virtual desktop — completely isolated from your workspace. You type, click, and work normally while the agent handles tasks in the background.

Zero Interruption

Agent operates on a separate Windows virtual desktop. Your windows, cursor, and workflow remain untouched.

Multi-Agent Scaling

Run multiple agents in parallel, each on its own virtual desktop. Scale automation without conflicts.

Visual Feedback

Animated cursor overlay with glide, pulse, and fade effects lets you monitor agent activity in real-time.

3-Tier Action Pipeline

Every interaction starts at the most reliable, invisible method. Only escalates to physical input if lower tiers can't reach the control. Smart, layered, fail-safe.

01

UI Automation

InvokePattern / ValuePattern

Direct programmatic access to UI elements. No mouse movement, no cursor — pure API-level control. Fastest and most reliable tier.

Preferred
02

PostMessage

WM_CLICK / WM_CHAR / WM_KEYDOWN

Sends Windows messages directly to application handles. Bypasses the input queue — no cursor needed, works even when windows are behind others.

Fallback
03

Physical Input

pyautogui / ctypes SendInput

Actual mouse and keyboard events as a last resort. Simulates real human input for apps that reject all other methods.

Last Resort

Built for Serious Automation

39 action types, 15 app profiles, forensic logging, approval gates, and a full workflow engine. Not a macro recorder — a complete automation platform.

Smart Wait Engine

Visual-diff detection, wait-for-text, wait-for-stable, wait-for-change, wait-for-color. The agent knows when pages load, modals appear, and processes finish.

Plain English Tasks

Describe your goal in natural language. Sentinel's AI breaks it into steps, selects the right actions, and executes autonomously. Works with 20+ LLM providers.

MFA Auto-Detection

Three-tier detection: window title analysis, OCR scanning, and UIA element inspection. Auto-pauses when authentication prompts appear so you can handle them manually.

Approval Gate

Pre-action review for sensitive operations. Approve, modify, skip, or abort any step before it executes. Full control, zero surprises.

Workflow Engine

Conditions, loops, variables, branching logic. Build complex multi-step workflows that go beyond simple task sequences. Full programmatic control.

Checkpoint and Resume

Auto-saves progress every 5 steps. If something interrupts the agent, resume exactly where it left off. No rework, no wasted time.

Forensic Audit Log

Every action recorded with timestamps, screenshots, and metadata. Export to JSON, CSV, HTML, or plain text. Full accountability for compliance and debugging.

Headless API Mode

FastAPI server with 35 REST endpoints and WebSocket support. Run Sentinel as a service, trigger tasks remotely, integrate with any system.

15 App Profiles

Pre-built profiles for Chrome, Excel, Word, Outlook, Cubism Editor, and more. Each profile includes optimized selectors, wait strategies, and action mappings.

Notification System

Toast popups, email alerts, webhook calls, and Discord messages. Know instantly when tasks complete, fail, or need your attention.

Script Recorder

Record your actions and play them back. Edit recorded scripts, combine with AI-driven tasks, and build reusable automation sequences.

RBAC and Credential Vault

Role-based access (VIEWER, OPERATOR, ADMIN) with DPAPI-encrypted credential storage. Enterprise-grade security for sensitive automation tasks.

What Sentinel Automates

If it runs on Windows, Sentinel can automate it. Here are the most common scenarios.

01

IT Operations and Sysadmin Workflows

Automate server health checks, log analysis, configuration updates, and deployment routines across multiple tools — PowerShell, RDP sessions, management consoles.

"Check all server statuses in the management console and email me a report"
02

Data Entry and Migration

Extract data from one application and enter it into another. Handle forms, spreadsheets, web portals, and legacy systems that lack APIs.

"Copy all new entries from the CRM into the accounting spreadsheet"
03

QA and Regression Testing

Run repeatable UI tests across desktop applications. Capture before/after screenshots, compare visual diffs, and generate test reports automatically.

"Open the app, run through the checkout flow, and screenshot each step"
04

Creative and Productivity Workflows

Automate repetitive tasks in creative tools, office applications, and specialized software — batch processing, template generation, report assembly.

"Open all PSD files in the folder, apply the export preset, and save as PNG"
