🎯 Screenium

Screenium is like Selenium after discovering there's a whole world outside the browser. Find and click any text on your screen using OCR. That "Accept Cookies" popup for the millionth time? Banish it.

🔍 Installation

pip install screenium

or

uv add screenium

✨ Use Cases

• Auto-Accept Cookies: Run a background task that automatically clicks "Accept Cookies" popups
• Meeting Assistant: Auto-join video calls by detecting "Join Meeting" buttons and automatically enable/disable your camera/mic based on meeting names
• Game Automation: Automate repetitive game tasks by detecting and clicking on in-game text (e.g., "Collect Rewards", "Start Battle")
• System Dialog Monitor: Handling system or application dialogs, like "Are you sure?" or "Run command," in Cursor based on set rules.
• Multi-Browser Testing: Perform UI tests on browsers that lack automation APIs or web drivers with no separate web driver installations needed.

🔍 Finding Text

The most basic way to find text is:

from screenium import Text

# Simple text matching
text = Text("Login")  # Finds "Login" anywhere on screen
text = Text("LOG")    # Matches the first of "LOGIN", "LOGOUT", etc.

# Exact matching
text = Text("Login", exact_match=True)  # Only matches "Login" exactly
text = Text("login", case_sensitive=True)  # Case-sensitive matching

📍 Spatial Relationships

You can find text based on its position relative to other text:

# Basic relationships
Text("Password").below("Username")  # Find "Password" below "Username"
Text("Cancel").left_of("Submit")    # Find "Cancel" left of "Submit"
Text("Help").right_of("Back")       # Find "Help" right of "Back"
Text("Title").above("Content")      # Find "Title" above "Content"

# Chain relationships
Text("Save").below("Options").right_of("Cancel")

📐 Aligned Elements

For more precise positioning, use aligned to require elements to line up:

# Elements must be vertically aligned (same x-axis)
Text("Email").aligned.below("Username")

# Elements must be horizontally aligned (same y-axis)
Text("Back").aligned.left_of("Next")

🎨 Background Color Matching

Find text by its background color:

# Match text with specific background colors
Text("Error", background_color="red")
Text("Success", background_color="green")
Text("Info", background_color="#0088ff")

# Adjust color matching tolerance (0-100)
Text("Warning", background_color="yellow", background_tolerance=50)

🖱️ Mouse Actions

Interact with matched text:

# Basic mouse actions
Text("Submit").click()
Text("Options").right_click()
Text("Link").double_click()
Text("Button").mouse_move()  # Just move mouse without clicking

# Type text
Text("Username").click().typewrite("myuser")
Text("Password").click().typewrite("mypass")

# Special keys
Text("Terminal").click().typewrite(["command", "k"])  # Clear terminal

⏰ Waiting and Monitoring

Handle timing and background monitoring:

# Wait for specific duration
Text("Loading").wait(2).click()  # Wait 2 seconds then click

🔍 Inspecting Matches

Get detailed information about matches:

# Get all matches
matches = Text("Button").matches
for match in matches:
    print(f"Found at: ({match['x']}, {match['y']})")
    print(f"Size: {match['width']}x{match['height']}")
    print(f"Confidence: {match['confidence']}")

🎨 Visual Debugging

Draw boxes around matches to debug:

# Draw green box for 3 seconds
Text("Username").draw(duration=3, color="green")

# Chain with other operations
Text("Password").below("Username").draw(duration=2, color="red").click()

🎯 Tips & Best Practices

1. Start with basic text matching before adding spatial relationships
2. Use draw() to visually verify matches
3. Adjust background color tolerance if color matching is too strict/loose
4. Use aligned when elements should line up precisely
5. Chain operations for more precise matching

⚠️ Limitations

• macOS only (uses Apple Vision framework)
• Requires macOS Monterey (12.x) or higher
• Screen resolution and scaling can affect matching

🔐 Required macOS Permissions

Screenium needs two key macOS permissions to function. The app running your Python script (e.g., Terminal, VS Code, PyCharm) will need:

1. Screen Recording

   • Open System Settings > Privacy & Security > Screen Recording
   • Toggle on your terminal app/IDE
   • Required for:
     • Finding text on screen using OCR
     • Background monitoring
     • Visual debugging with draw()

2. Accessibility

   • Open System Settings > Privacy & Security > Accessibility
   • Toggle on your terminal app/IDE
   • Required for:
     • Mouse actions (click(), right_click(), etc.)
     • Keyboard input (typewrite(), hotkey())

💡 Tip: If running from different apps, each one needs separate permissions. For example, if you run scripts from both Terminal and VS Code, you'll need to grant permissions to both.
