Expert AI Total above is roughly double this — it also counts the unlimited free-tier fallback you get once your paid balance runs out.
Haiku runs everyday chat; Sonnet steps in on hard tasks or when you say "review".
Subscribe sets up real autopay (Razorpay UPI/card mandate) — charged automatically each cycle until cancelled. "Buy once" is a single manual charge with no auto-renewal.

A tool call adds only a few hundred tokens to a message, not a separate charge on top of it — on the ≈₹860 Expert tier's roughly 1M paid tokens (before its own unlimited fallback kicks in), that's easily 1,500–2,000 ordinary chats, each free to reach for a calculator, weather check, or web search along the way.
