+## AI Features Vision (v2.0+)
+
+These are the "smart" features planned for future releases:
+
+### Cooking Intelligence
+- **Ingredient substitutions** — "Out of buttermilk? Use milk + vinegar"
+- **Meal planning** — Generate weekly menus from your recipe collection
+- **Shopping lists** — Aggregate ingredients, de-duplicate, organize by grocery aisle
+- **Recipe recommendations** — "You haven't made this in 3 months, try it tonight!"
+
+### Data & Integration
+- **Nutrition estimates** — Calorie/macro breakdown via USDA database
+- **Fintrove integration** — Track recipe costs, generate budget-aware meal plans
+- **Recipe costing** — "This dinner costs $4.50/serving"
+
+### Advanced Input
+- **Voice input** — Add ingredients/steps via speech-to-text
+- **OCR import** — Scan physical recipe cards or cookbooks
+- **Smart parsing** — AI-enhanced recipe extraction from non-standard sites
+
+**Why later?** Need MVP data (recipes + usage patterns) to tune AI features effectively. Scraping comes first so Anne & Elizabeth can import their existing collections.
