What is Ai Real Estate Assistant?
The AI Real Estate Assistant is a conversational AI application designed to help real estate agencies assist potential buyers and renters in finding their ideal properties. The application uses natural language processing and machine learning to understand user preferences and recommend suitable properties from a database through intelligent conversation.
The tool implements a Retrieval-Augmented Generation (RAG) system that combines large language models with structured property data to provide intelligent property recommendations. It supports natural language conversation where users can express preferences like

Pricing model: Freemium
The application is open-source under Apache License 2.0 and free to use. It can be deployed locally or to Streamlit Cloud at no cost. Users need their own OpenAI API key for GPT models which incurs separate usage costs from OpenAI. Open-source Llama models provide a free alternative without API costs. The tool uses free in-memory vector storage (DocArrayInMemorySearch, ChromaDB) and free data processing with Pandas.

Ai Real Estate Assistant cons
- Quality depends heavily on completeness of property data
- Cold start challenges without sufficient initial information
- Current implementation has db freeze issue during heavy processing
- Limited visualization - currently text-based only

Frequently asked questions about Ai Real Estate Assistant
What is the AI Real Estate Assistant?
The AI Real Estate Assistant is a conversational AI application designed to help real estate agencies assist potential buyers and renters in finding their ideal properties. It uses natural language processing and machine learning with a Retrieval-Augmented Generation (RAG) system to understand user preferences and recommend suitable properties through natural conversation.
How does the property search work?
The system uses vector embeddings generated by FastEmbed to convert property data into semantic representations stored in ChromaDB or DocArrayInMemorySearch. When users ask questions in natural language, their query is processed through an LLM to extract preferences, which are then used to query the property database through vector similarity search, returning the most relevant properties.
What data formats does it support?
The application supports CSV datasets with standardized columns including id, city, type, square_meters, rooms, floor, price, has_parking_space, has_balcony, has_elevator, and many other property attributes. Data can be loaded from local CSV files or external data sources via URLs.
Which AI models can I use?
The V2 implementation supports multiple LLM models including OpenAI GPT models and open-source alternatives like Llama. This provides flexibility and cost options, allowing users to choose between premium OpenAI models or free open-source models depending on their needs.
Can I use this without paying for OpenAI?
Yes, the V2 implementation supports open-source Llama models as an alternative to OpenAI GPT models. Users can run Llama models locally without API costs, though OpenAI models may provide better performance for some use cases.
How do I deploy this application?
The application can be run locally using Streamlit with commands like 'streamlit run app_v2.py', deployed to Streamlit Cloud, packaged as a Docker container using './utils/run_docker.sh', or run in a development container using './utils/run_dev_container.sh'.
What is the difference between V1 and V2?
V1 uses a Pandas DataFrame Agent with single-turn conversations and limited to OpenAI. V2 uses ConversationalRetrievalChain for multi-turn conversations with history, supports multiple LLM models (OpenAI and Llama), implements RAG for enhanced reasoning, and provides more relevant personalized recommendations with improved conversation memory.
Does the assistant remember previous conversations?
Yes, V2 implements ConversationBufferMemory to store and retrieve conversation history, enabling the system to remember previous interactions and build cumulative understanding of user needs across multiple turns of conversation for more natural conversation flow and follow-up questions.
What property attributes can I search by?
Users can search by city, property type, square meters, rooms, floor, build year, price, parking space, balcony, elevator, security, storage room, garden, pool, garage, bike room, ownership type, building material, condition, and proximity to schools, clinics, restaurants, and other points of interest.
Is this tool free to use?
Yes, the AI Real Estate Assistant is open-source under Apache License 2.0 and free to use. It can be deployed locally or to Streamlit Cloud at no cost. The only potential cost is if users choose to use OpenAI GPT models which require their own API key with usage-based pricing; open-source Llama models provide a completely free alternative.
