The Problem: AI Tools Are Getting Expensive

Most users today rely on multiple AI tools:

• ChatGPT Plus — ₹1,999/month
• Google AI Pro — ₹1,950/month
• Transcription tools — ~₹320/month

👉 Total: ₹4,269/month (~$42)

And all of them require:

• Constant internet
• Cloud processing
• Data sharing

This is where on-device AI changes everything.
