# PropertyIndex > PropertyIndex is a Dubai real estate data platform built on Dubai Land Department sales and Ejari rental contracts. It is approved by the DLD under the REES Initiative. Its plugins for ChatGPT and Claude give AI assistants the most accurate Dubai property prices available: the sold price DLD recorded for each sale and the rent on each Ejari contract, not asking prices or estimates. It also publishes PIX©, the Dubai real estate index, every month. Every page below is Markdown. Each one opens with a map of the whole guide set, so you can move between pages from any of them. ## AI for Dubai Real Estate - [AI for Dubai Real Estate](https://www.propertyindex.ae/ai-for-dubai-real-estate.md): How ChatGPT and Claude answer Dubai property questions, where their figures come from, and what changes when Dubai Land Department sales and Ejari rents are connected. - [Why ChatGPT and Claude Get Dubai Property Prices Wrong](https://www.propertyindex.ae/ai-for-dubai-real-estate/why-prices-are-wrong.md): The six reasons an AI assistant misprices Dubai property, and the data that corrects each one. - [How to Connect DLD Data to ChatGPT and Claude](https://www.propertyindex.ae/ai-for-dubai-real-estate/connect-dld-data.md): Install the PropertyIndex plugin for ChatGPT or Claude and ask about DLD sales and Ejari rents in plain language. - [How to Ask AI What a Dubai Property Sold For](https://www.propertyindex.ae/ai-for-dubai-real-estate/sold-prices.md): Get sold prices for a Dubai building, layout or unit from ChatGPT or Claude: the most accurate prices in Dubai, with the DLD sales behind every figure. - [AI Property Valuation in Dubai](https://www.propertyindex.ae/ai-for-dubai-real-estate/valuation.md): How ChatGPT and Claude value a Dubai property from comparable DLD sales, and where an AI valuation stops. - [AI Property Investment Analysis in Dubai](https://www.propertyindex.ae/ai-for-dubai-real-estate/investment-analysis.md): Use ChatGPT or Claude to calculate rental yield and resale gains for a Dubai project from DLD sales and Ejari rents. - [Using AI to Check a Dubai Rent Increase](https://www.propertyindex.ae/ai-for-dubai-real-estate/rent-increase.md): Compare your rent with new Ejari contracts and renewals in your building, then read it against the RERA rental index rules. - [AI Off-Plan Due Diligence in Dubai](https://www.propertyindex.ae/ai-for-dubai-real-estate/off-plan.md): Use ChatGPT or Claude to check an off-plan project, its developer and the off-plan market against DLD sales. - [Monitoring the Dubai Property Market with AI](https://www.propertyindex.ae/ai-for-dubai-real-estate/market-monitoring.md): Ask ChatGPT or Claude for the monthly direction of Dubai prices, by segment and community, from the PIX© index and DLD sales. - [AI for Dubai Real Estate Agents](https://www.propertyindex.ae/ai-for-dubai-real-estate/agents.md): How Dubai brokers use ChatGPT and Claude with DLD data for comparable sales, pricing conversations and client reports. - [ChatGPT and Claude Prompts for Dubai Real Estate](https://www.propertyindex.ae/ai-for-dubai-real-estate/prompts.md): Copy-ready prompts for ChatGPT and Claude that return Dubai sold prices, rents, yields, valuations and market direction. ## Optional - [Every AI for Dubai Real Estate page in one file](https://www.propertyindex.ae/ai-for-dubai-real-estate/all.md): the pillar and all 10 guides, concatenated.
