How to Use Each Feature
Traditional Text Search (Free)
Press Ctrl+F (Windows/Linux) or Cmd+F (Mac)
Type your search term in the search box
Use Enter to go to next match, Shift+Enter for previous
Press Esc to close the search interface
Traditional Search Tips
- Exact phrases are always prioritized
- Search is not case-sensitive by default
- Works instantly without any account or tokens
- Perfect for finding exact text or advanced regular expressions
AI-Powered Search (Requires Tokens)
Sign in with your Google account through the extension popup
Ensure you have available tokens (50 free tokens topped off monthly)
Open the Smart Finder interface (Ctrl+F or Cmd+F)
Switch to AI search mode by clicking the AI toggle (on by default) or typing a natural language query
Ask questions like:
- "What are the main points on this page?"
- "Find the author and title of this article"
- "Show me the pricing information"
- "Contact information"
- "Important dates"
- "Key statistics or numbers"
AI Search Tips
- Be specific: "Find the CEO's name" works better than "find names"
- Use context: "What's the return policy?" instead of just "return"
- Ask questions: AI understands natural questions better than keywords
- Try different approaches: If one query doesn't work, rephrase it
Custom AI Prompts (Advanced)
Open the extension popup and scroll to "Advanced Settings"
Click to expand the advanced settings section
Edit the "Custom System Prompt" textarea
Define your desired AI behavior (e.g., "Only return names of people")
Click "Save Custom Prompt" to apply your changes
Use AI search as normal - it will follow your custom instructions
Regex & Pattern Search
Smart Finder includes powerful regex (regular expression) capabilities for advanced pattern matching. This feature is completely free and doesn't require any tokens or account.
Automatic Pattern Detection
Just type common pattern names and Smart Finder automatically converts them to regex:
Type this: Finds:
"email" → All email addresses (user@domain.com)
"phone" → Phone numbers (555-123-4567, (555) 123-4567)
"url" → Web addresses (https://example.com)
"date" → Dates (12/31/2023, March 15 2024, Jan 3rd)
"time" → Times (3:30 PM, 15:30)
"address" → Street addresses (123 Main St, 456 Oak Ave Apt 2B)
"state" → US states (California, TX, New York)
"country" → Countries (United States, Canada, Germany)
"city" → Cities and towns (New York City, San Francisco)
"ip" → IP addresses (192.168.1.1)
"zip" → ZIP/postal codes (12345, K1A 0A6, SW1A 1AA)
Manual Regex Search
Open Smart Finder (Ctrl+F or Cmd+F)
Click the settings gear next to the search box
Enable "Regex Mode" checkbox
Type your regular expression in the search box
Results will be highlighted automatically
Regex Examples
Pattern: Finds:
\d{3}-\d{3}-\d{4} Phone numbers (123-456-7890)
\b\w+@\w+\.\w+\b Email addresses
https?://\S+ URLs starting with http/https
\$\d+(\.\d{2})? Prices ($19.99, $100)
\b[A-Z]{2,}\b Acronyms (NASA, FBI, API)
\d{1,2}/\d{1,2}/\d{4} Dates (12/31/2023)
Multi-Term Regex
Search for multiple patterns at once with different highlight colors:
Enable both "Regex Mode" and "Multi-term Highlighting"
Separate patterns with spaces, use quotes for complex patterns
Example: email phone "https?://\S+"
Each pattern type will be highlighted in a different color
Regex Tips
- Start simple: Use pattern detection first ("email", "phone") before writing complex regex
- Quote complex patterns: Use quotes around patterns with spaces or special characters
- Case sensitivity: Toggle case-sensitive mode in settings for exact matches
- Test patterns: Invalid regex will show an error - check your syntax
- Common characters to escape:
. + * ? ^ $ | ( ) [ ] { } \
Security Note
Regex searches are processed locally in your browser - no data is sent to our servers. Your search patterns and page content remain completely private during regex operations.
Token System & Pricing
Important: Failed Searches Don't Cost Tokens
- Tokens are only consumed when AI search finds relevant results
- If AI search finds no matches, you keep your token
- Network errors or search failures are completely free
- You're only charged for successful AI searches that return results
How Tokens Work
Free Tokens: Monthly allocation with automatic reset (check extension popup for current amount)
AI Search Cost: Variable tokens per successful search - depends on content length and complexity
Token Usage: Longer pages may require multiple tokens due to batch processing
Failed AI Searches: 0 tokens (no charge when no results found)
Traditional Text Search: Always free (unlimited)
Regex Search: Always free (unlimited)
Pattern Detection: Always free (unlimited)
Multi-term Highlighting: Always free (unlimited)
Token Consumption Rules
When Tokens ARE Consumed
- AI search successfully finds and highlights relevant content
- AI search returns text snippets that match your query
- AI successfully processes your natural language query
- Multiple tokens may be consumed for longer pages due to batch processing
- Token usage scales with content length and search complexity
When Tokens Are NOT Consumed
- AI search finds no relevant results - you keep your token
- Network connection errors - no charge for failed requests
- Invalid queries or processing errors - technical failures are free
- Traditional text search - always free regardless of results
