Bulduk

"Sen anlat. İyi olanı bulduk." You tell Bulduk what you want in plain Turkish or English; it asks a couple of follow-up questions, then compares real offers across Turkey's biggest stores.

• Streaming chat with tappable answer chips to narrow down quickly.
• Product cards with offers across stores and side-by-side comparison.
• Saved items and price-drop push alerts.
• Remembered preferences — sizes, brands, budget.
• Native iOS (SwiftUI) and Android (Compose) apps and a bilingual landing site.

A Python FastAPI backend with Postgres and Redis, streaming responses over Server-Sent Events.

• LLM provider failover — Claude by default, then OpenAI and Gemini — with conversation history stored in a provider-neutral format so a chat can move between models.
• Config-driven product categories, so adding a vertical is data, not code.
• Affiliate redirects tracked through click IDs; anonymous, Google, Apple and email sign-in.
