This project was built for my travel-savvy friend who loves travelling and exploring India’s rich heritage who finds traditional museum plaques dry and standard image-search tools uninformative. So I built an interactive, personal, multi-turn AI tour guide right in their pocket.

The Indian Monument Identifier & Interactive AI Guide is a web-based, memory-aware application that allows users to drag-and-drop a photo of any Indian historical landmark to instantly receive a structured, rich cultural guide.

**Instant Visual Recognition:** Identifies monuments from user-uploaded images without needing a pre-categorized or hardcoded database.

**Structured Cultural Output:** Generates formatted breakdowns covering Monument Name & Location, Built Era / Ruler, Architectural Style and Key Historical Facts.

**Conversational Thread Memory:** Maintains multi-turn session context, allowing the user to ask natural follow-up questions (e.g., "What is the best time of year to visit?" or "What other sites are nearby?") without re-uploading the photo

The application bridges a Streamlit front-end with a Python async backend orchestrated by the Backboard API:

**Frontend Interface (Streamlit):**

Built a drag-and-drop file uploader accepting .jpg, .png, and .webp images.

Handles user inputs, displays live image previews, and renders Markdown response outputs seamlessly.

**Backend Orchestration (Backboard SDK):**

Assistant Initialization: Spawns a dedicated AI assistant configured with a persistent system_prompt acting strictly as an expert Indian historian.

Thread Management: Initializes a session thread (client.create_thread()) to store conversation history and visual context on Backboard’s servers.

Multimodal Routing: Passes the temporary local image path directly through Backboard (files=[file_path]) to multimodal vision models (gpt-4o or open-weight vision alternatives).

**Open-Source AI & Framework Core:**

Async Runtime & SDK: Powered by standard open-source Python packages (asyncio, streamlit, tempfile) and the backboard-sdk.

Model Agnosticism: Constructed around open-source agent integration frameworks, allowing the app to route queries across open-weight vision models (e.g., Gemma Vision variants) or commercial endpoints via Backboard’s unified gateway.

**Zero-Shot Flexibility vs. Closed Models:** Closed vision APIs force you to use rigid, pre-categorized classifiers that only output flat text labels (e.g., Taj_Mahal). Open-source, multimodal AI enables zero-shot visual understanding, eliminating the need to collect, label, and train expensive custom datasets on thousands of monument photos.

**No Vendor Lock-In via Backboard:** Closed APIs lock you into proprietary SDKs. Using Backboard's open orchestration framework abstracts model provider logic—swapping underlying vision models (or comparing open-weight models) requires changing just a single parameter string (model_name) without rewriting thread memory or upload pipelines.

**Democratizing Cultural Access:** Open innovation lets developers build low-cost, high-impact tools that turn static historical plaques into personalized, interactive AI tour guides accessible to everyone without expensive subscription costs.

Best Use of Backboard ($100 USD + Exclusive Winner Badge):

Built using Backboard’s unified API and SDK to manage multimodal visual inputs (files=[...]), maintain session thread context across user queries, and enforce system prompt guardrails for historical accuracy.
