3. The calculator sends current inputs + results as hidden context to the AI
4. AI provides personalized insights, comparisons to local benchmarks, and actionable recommendations
5. AI recommends a related forward-looking calculator with pre-filled parameters

**Context sent to AI includes:**
- Calculator type and name
- All current input values
- All calculated output values
- User's language code
- User's currency and country (from CurrencyContext)

**AI response structure:**
- Warm, personalized feedback on the results
- Concrete future projections
- Comparison to local benchmarks (average salary, typical expenses)
- A complementary calculator recommendation with pre-filled params
- The response concludes with the recommended calculator name in bold

**Analysis constraints:**
- Housing vs Stocks: calculates investment gap as "mortgage minus rent", sets initial = down payment
- Killer Fees: acknowledges the fee gap and suggests investing savings differently
- Inflation: never recommends "holding more cash" — always recommends investing
- Young Millionaire/FIRE: suggests tweaking inputs (savings, target age, return rate)
- Avoids historical/backward-looking tools (Bitcoin, S&P 500) during analysis; favors forward-looking planning tools

**Example (Latte Factor, SAR):**
Input: 15 ر.س/day, age 28, retire at 65, S&P 500
Result: 892,000 ر.س
AI response: "892,000 ر.س يعادل 111 سنة من الراتب السعودي المتوسط. لمعرفة كيف تصل لاستقلالك المالي أسرع، جرب **حاسبة FIRE**: [/ar/fire-number?expenses=8000&currency=SAR](/ar/fire-number?expenses=8000&currency=SAR)"

**Example (Compound Interest, BRL):**
Input: R$ 5,000 initial, R$ 500/mo, 10%, 25 years
Result: R$ 740,000
AI response: "R$ 740,000 é um patrimônio impressionante! Isso representa mais de 12 anos de salário médio brasileiro. Para saber quando você pode parar de trabalhar, veja a **Calculadora FIRE**: [/pt/fire-number?expenses=3000&saving=500&current=5000&currency=BRL](/pt/fire-number?expenses=3000&saving=500&current=5000&currency=BRL)"
