RealensAI MVP Proposal

Automated Market Analysis for Real Estate Agents

Rebar proposes building RealensAI, a lightweight web application that transforms real estate's most time-intensive task: market analysis for listing presentations. Agents simply upload MLS CSV data and instantly receive professional pricing strategies and market trend summaries.

By combining deterministic data processing with AI-generated insights, this MVP delivers fast, reliable, agent-quality reports in minutes instead of hours. This proof-of-concept will fundamentally change how agents approach market analysis and client communication.

Core Features and Requirements

Rebar proposes a strategic two-tier approach for the RealensAI MVP, prioritizing essential functionality for rapid launch while identifying high-value enhancements for subsequent phases. This structured methodology ensures we deliver maximum value within our aggressive timeline while maintaining flexibility for future expansion.

User Management

Secure authentication with Google social sign-in provides streamlined access while maintaining enterprise-grade security standards for protecting sensitive MLS data.

Data Ingestion

Sophisticated CSV parsing handles common MLS export formats, with intelligent field validation and data cleaning ensuring accurate downstream analysis.

AI Analysis Engine

Integration with leading LLM APIs combines probabilistic AI generation with deterministic calculation layers for precise, professional-grade insights.


Tier 1: Essential MVP Features

  • User Management: Secure login and basic account creation functionality with social sign in for Google.
  • Data Ingestion:
  • CSV upload capability (specifically designed for a single export file formats).
  • Data parsing and basic field validation to clean and structure the imported MLS data.
  • AI Analysis Engine:
  • Integration with a capable LLM API (e.g., OpenAI) for probabilistic analysis and narrative generation.
  • Deterministic software layer for precise data calculation prior to LLM input.
  • Core Analytics Processing: Calculation of key market metrics:
  • Days on Market (DOM).
  • Percentage of listings with price reductions.
  • Average price reduction amount.
  • Original list vs. final list vs. sold price ratios (LTS, STL, etc.).
  • Overall trend summary calculation.
  • Report Generation:
  • AI-generated narrative summary providing professional, agent-style insights based on the calculated data.
  • Basic report export functionality (PDF or easy-to-copy text format).


Tier 2: High-Value Enhancements

If project scoping reveals capacity within our target budget and timeline, Tier 2 features will significantly enhance the user experience:

  • Basic charting and data visualization (e.g., visual representation of price reduction percentages over time).
  • "Improve analysis" regeneration option, allowing the user to request a new narrative based on the same dataset.
  • Simple custom text fields for agents to add personal notes or context before report generation.
  • Fine-tuning the AI tone to match a specific, consistent "agent voice."
  • Direct export into common formats like email or Google Docs.

These enhancements transform the MVP from a functional tool into a comprehensive workflow solution.

Proposed User Journey

Agent User Journey in Production Application

Understanding how agents will interact with RealensAI in daily practice provides crucial context for development priorities and UX decisions. The following workflow represents the complete agent experience from initial login through final report export. The final user flow will be determined in scoping.

01

Secure Authentication

Agent accesses web application and authenticates (username or SSO), landing on the main Properties Page dashboard.

02

Data Upload Initiation

Agent clicks "Upload New" button and uploads raw MLS export CSV file. Parser performs validation and data cleaning, converting to structured JSON.

03

Automated Analysis Engine

Deterministic processing layer calculates precise market metrics (DOM, price reductions, ratios). Data and metrics are sent to LLM API via Vercel AI SDK.

04

AI Narrative Generation

AI agent generates professional, agent-voice narrative summary based on calculated metrics and contextual data from the upload.

05

Storage and Access

Original CSV saved to Supabase Storage. Metrics, AI report text, and file reference stored in Postgres database for future retrieval and analysis.

06

Report Review and Export

Agent views complete AI-generated report with supporting data visualization. Exports final report as PDF or copyable text format for client presentation.

This streamlined workflow transforms what traditionally requires hours of spreadsheet analysis, calculation verification, and narrative writing into a simple upload-and-export process. The time savings allow agents to focus on high-value client relationship activities rather than manual data processing, while still delivering professional-grade analysis that builds client confidence and trust.

Proposed Technology Stack

Rebar proposes a RealensAI architecture that leverages our deep expertise while maintaining flexibility for future evolution. Our technology selections prioritize rapid development velocity, scalability, and cost-effectiveness while ensuring the platform remains adaptable as requirements evolve and new AI capabilities emerge.

Frontend Architecture

Svelte 5: Desktop-optimized web application delivering exceptional performance and responsive user experience. Svelte's compile-time optimization ensures minimal bundle sizes and lightning-fast interactions.

Backend & Logic Layer

SvelteKit Serverless + Supabase Edge Functions: Distributed computing architecture provides secure, scalable request handling with minimal latency and optimal resource utilization.

Data Layer

Supabase (Postgres): Enterprise-grade relational database securely stores user accounts, historical analyses, and metadata. Supabase Storage handles CSV uploads and generated PDF reports with robust access controls.

AI Integration

Vercel AI SDK: Model-agnostic architecture enables seamless switching between OpenAI, Gemini, xAI, and Anthropic. This prevents vendor lock-in and allows leveraging unique strengths of each platform as the AI landscape evolves.

Architecture Philosophy

Our stack emphasizes composability and future-proofing. The serverless approach eliminates infrastructure management overhead while providing automatic scaling. The model-agnostic AI layer is particularly critical—as new models emerge with superior performance or specialized capabilities, the platform can adapt without requiring fundamental architectural changes.

This flexibility extends to cost optimization. By maintaining the ability to route different types of analysis to the most cost-effective or capable model, we ensure long-term operational efficiency and competitive advantage.
