HOW IT WORKS
─────────────────────────────

   phone, company — any fields you need)
2. Visit any website with a form
3. Click Fill Page — AI fills every field instantly

KEY FEATURES
─────────────────────────────
🤖 Real AI Field Matching
   Works even when field labels are unusual or don't 
   match your profile keys exactly. AI figures it out.

📋 Multi-Step Form Support
   Forms that span multiple pages are handled 
   automatically. FillFast follows the flow.

📷 Capture Any Form
   Already filled a form? Capture it as a reusable 
   profile in one click. Never retype it again.

🔒 Your Data Never Leaves Your Device
   Profiles are stored locally in your browser only. 
   Only field labels are sent to AI — never your values.

🎭 Indian Persona Engine
   Generates realistic Indian data — valid PAN, GSTIN, 
   Aadhaar, IFSC, real addresses with matching 
   city/state/PIN — perfect for QA testing.

⌨️ Keyboard Shortcuts
   Alt+Shift+F to fill. Alt+Shift+A to analyze. 
   Hands never leave the keyboard.

🔍 Analyze Any Form
   AI scans the page and suggests profile keys 
   with realistic sample values automatically.

📌 Persistent Side Panel
   Stays open while you navigate multi-step forms. 
   No more reopening the extension on every page.
