  • Multi-agent AI router
    A planning-route + triage layer picks the right specialist agent for each question (market analysis, borough comparison, planning evidence, rent-vs-buy). No generic chatbot guessing — every query goes to a purpose-built agent.
  • Audited accuracy
    Answers are computed live from 1.76M Land Registry rows, not summarised by an LLM. Published accuracy audit vs GPT-class models shows OpenProp matches the raw data on 100% of price/volume queries where general chatbots hallucinate boroughs and invent figures.
  • Auto-generated charts & heatmaps
    Every answer ships with the relevant visual — borough heatmaps, year-over-year trend lines, price distribution histograms — rendered on the fly from the same query, no separate dashboard tool needed.
  • One-click planning evidence reports
    Automates what consultants charge £500–£2k for: enter a postcode and objection type, get a structured PDF report with supporting transaction data, ready to submit to a council planning committee.

Overall verdict

  • OpenProp.co.uk appears to be a property listing and portal service, but without verified independent reviews, extensive user feedback, or established market presence data, it's difficult to fully assess its reliability and quality. Users should conduct their own due diligence before relying on this platform for significant property transactions.

Why this product is good

  • May offer property listings that could be useful for browsing available properties
  • Could provide a simpler, more focused interface compared to larger property portals
  • Potentially lower cost or free listing options for property owners or agents

Recommended for

  • Users seeking additional property listing sources beyond major portals
  • Property owners looking for alternative or supplementary advertising platforms
  • Buyers or renters wanting to cross-reference listings across multiple sites
  • Those who prioritize verifying platform legitimacy before committing to use it exclusively

Questions & Answers

As answered by people managing Diffee and OpenProp.co.uk.

What makes your product unique?

OpenProp.co.uk's answer:

OpenProp computes every answer live from 1.76M HM Land Registry transactions instead of summarising scraped portal listings or relying on an LLM's memory. A multi-agent router sends each question to a purpose-built specialist (market analysis, borough comparison, planning evidence, rent-vs-buy), so answers come back with the underlying numbers, charts, and transaction counts — not a confident guess.

Why should a person choose your product over its competitors?

OpenProp.co.uk's answer:

PropertyData and LandInsight cost £50–£500/month and require a property-industry login. Zoopla and Rightmove show asking prices, not sold prices. ChatGPT hallucinates London boroughs. OpenProp is £1.99 for 10 queries, one-off, no subscription — answers are auditable against the raw Land Registry source on every query, and every answer ships with the chart or heatmap that backs it.

How would you describe the primary audience of your product?

OpenProp.co.uk's answer:

First-time buyers, renters deciding which borough to commit to, family upsizers, relocators moving into London, planning consultants and residents preparing objection evidence, and journalists who need defensible numbers fast. Anyone who needs a real answer about London property without paying agency rates or trusting a chatbot.

What's the story behind your product?

OpenProp.co.uk's answer:

Built by a solo data scientist who got tired of watching friends make six-figure London property decisions on the back of Rightmove asking prices and Zoopla "estimates." Open data exists — HM Land Registry publishes every London sale under OGL v3.0 — but it's a 5GB CSV most people can't open. OpenProp is the layer that turns that public dataset into plain-English answers anyone can use.

Which are the primary technologies used for building your product?

OpenProp.co.uk's answer:

  • Python 3.11
  • FastAPI (backend API)
  • Anthropic , xAI, OpenAI
  • Pandas + PyArrow (computation on Parquet datasets)
  • Plotly (charts and heatmaps)
  • PostgreSQL (sessions, billing)
  • Stripe
  • Cloudflare Pages
  • Hugging Face Hub
  • Kaggle
