Three directions
Three possible content directions
The next step was content and voice. I took the same Kotak recommendation and wrote three genuinely different versions. Not rewrites, but different assumptions about how financial advice should speak to someone making a real decision.
Direction 01
Evidence First
Led with reasoning before making the recommendation
Your savings could be earning ₹4,482 more each year
Your average HDFC balance is ₹62,000. At Kotak's current 7.1% rate, that balance could earn more than HDFC's 3.5%.

Direction 02
Conversational-First
Make the AI sound like an advisor opening a conversation rather than delivering a verdict
There's an opportunity to earn more on your savings.
Based on the balance you usually keep in HDFC, Kotak ActiveMoney could earn your around ₹4,482 more per year.
But higher returns aren't the only thing that matters. Your minimum balance, fees, and how you use the account could change whether switching makes sense for you.

Findings
Direction 01
Evidence First
Trusted, but didn't move people.
High trust, low action. Caveats made people pause.
Direction 02
Conversational-First
Felt human, but the point got lost.
Warm, but the soft opening buried the recommendation.
Direction 03
Trade-Off Upfront
Clearest, but least trusted.
Fastest to understand, but read like a spec sheet.
No direction won on everything: trust, warmth and clarity each came from a different voice.
