π Room Finder
π― Tagline
Natural language room search meets AI-powered semantic matching. Find your next home by describing what you want, not typing filters.
π‘ Inspiration
Finding a room shouldn't require mastering filter menus and apartment-hunt jargon. Most room-finder platforms force users into rigid search criteria (1-2 bedrooms, $1500-$2000, near downtown), but real people describe what they want naturally:
"I need a quiet 2BR with good light, walkable to the metro, and a kitchen big enough for two people"
We built Room Finder MVP to bridge that gap: turn natural language into intelligent, semantically-aware search results.
π₯ What It Does
Search Like You Talk
Type in natural language (e.g., "bright studio near downtown with laundry in unit") and our NLP parser extracts structured criteria. Behind the scenes, Backboard.io RAG understands intent and reorders results by semantic relevance.
Frictionless Viewing Requests
Found a room you love? Click "Request Viewing" to instantly start a messaging thread with the owner. No auto-calendar complexityβjust you and the owner negotiating times via in-app chat.
Smart Result Ranking
Results are ranked by:
- Structured criteria match (location, bedrooms, price)
- Keyword overlap (textual relevance)
- RAG suggestions (semantic understanding of user intent)
Real-time Sync
Listings auto-sync from external sources and are immediately indexed in the RAG system for fresh results.
π Key Features
β¨ Core
- NLP-powered search: Parse "2BR near downtown under $2500" into structured filters
- RAG semantic reordering: Backboard.io understands intent and boosts relevant listings
- In-app messaging: Real-time communication with room owners
- Viewing timeline: Track viewing requests from proposal β confirmation
π Behind the Scenes
- Auto-sync: Listings refresh automatically (configurable intervals)
- Interaction tracking: User views, bookmarks, and rejections feed back into recommendations
- Status machine: Viewing requests move through states (requested β time_proposed β confirmed)
- Event logs: Full audit trail of all actions for debugging

π What We Learned
- RAG is powerful: Semantic search catches intent that purely keyword-based systems miss
- Schema validation matters:
Zodcaught API contract errors early - Service layers scale: Separating business logic from routes made testing & iteration fast
- Messaging is underrated: Simple chat is often better UX than complex automation
- In-memory state is dangerous: For production, move
events,messages,viewingRequeststo a database - Events are audit gold: Recording every state change makes debugging 10x easier
