As answered by people managing Propelos and Diffyn.
Propelos's answer
Propelos offers three distinct products for real estate agencies: AI property search, a complete real estate website platform, and AI visibility (GEO). Agencies can use any of these independently or combine them into a single solution.
The AI property search lets buyers search live listings conversationally in 95+ languages. The website platform provides the technology to build and operate a complete agency website. The GEO platform independently monitors and improves how an agency appears in ChatGPT, Gemini, Claude, Google AI Mode and other AI-powered search experiences.
This means an agency can add AI search to its existing website, build a new website with Propelos, use GEO without changing its website at all, or combine all three.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Propelos's answer
Propelos gives agencies the flexibility to solve a specific problem without having to replace everything. An agency can use Propelos for AI property search on its existing website, use the website platform to build and operate a new site, or use the GEO platform independently to improve its visibility in AI search.
The products can also work together when an agency wants a complete solution. This modular approach means agencies aren't required to adopt a new website or CMS simply to use Propelos' AI visibility tools, or vice versa.
Propelos is also built specifically for real estate, with support for complex property searches, live listing data and international buyers across 95+ languages.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
Propelos's answer
Propelos combines modern web technologies, AI models and real estate data infrastructure. The technology behind the platform includes natural-language AI for property search and matching, real-time property feeds, mapping, analytics, high-performance web infrastructure and integrations with CRM and lead-management systems.
The GEO platform uses AI-search monitoring and analysis to track how real estate agencies appear across AI assistants and search experiences, including competitor visibility and cited sources.

Propelos's answer
Propelos is built primarily for real estate agencies, particularly agencies selling residential and luxury property in competitive and international markets.
Different parts of the platform address different needs: agencies can use AI property search to improve the buyer experience and generate enquiries, the website platform to build and operate their website, and the GEO platform to monitor and improve their visibility across AI search engines and assistants.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Propelos's answer
Propelos was founded around a simple observation: the way people discover and search for property is changing. Buyers increasingly expect to describe what they want in natural language, while AI assistants are becoming another way people discover businesses and products.
We built Propelos to help real estate agencies adapt to both changes. The company began with AI-powered property search and expanded into three complementary products: AI property search, real estate website technology and AI visibility (GEO).
Propelos is based in Spain and is certified as an empresa emergente by ENISA, Spain's Ministry of Industry and Tourism.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
