How can real estate companies use RAG for internal knowledge?

Key facts

API surface	OpenAI-compatible /v1/chat/completions; change base_url and model name
Models	30+ models including long-context and multilingual options
Retrieval	Embeddings and RAG are live for real estate document search with citations
Agents	Function calling and agent orchestration are live
Deployment	Plugsky cloud, your VPC, on-prem or air-gapped
Data residency	Region selection and sovereign deployment options
Free tier	Free plan with 2 free AI models (plugsky-micro, plugsky-lite), no card
Endpoint roadmap	Audio, images, moderation, batch and fine-tuning are coming soon

TL;DR

• Put listings, title documents and leases behind a cited RAG assistant.
• Deploy in your VPC, on-prem or air-gapped so listing and deal data stays inside your boundary.
• Embeddings and RAG are live today; audio and image endpoints are on the roadmap.
• Function calling lets agents read listing and transaction systems on request.
• Evaluate on the free plan, then move to a private deployment for production.

How it works, step by step

1. Inventory document sources: listings, title and due-diligence documents, leases, appraisals and market reports.
2. Classify content by sensitivity and decide what may leave an on-prem or air-gapped boundary.
3. Create a Plugsky account and API key on the free plan, or request a private deployment.
4. Chunk and embed approved documents, keeping the vector store inside your own environment if required.
5. Wire retrieval into an assistant that cites sources and refuses out-of-scope questions.
6. Add function calling for listing and transaction systems once retrieval is trusted.
7. Log queries and answers, review them weekly, and expand coverage document class by document class.

Where real estate teams get value first

Start with document-heavy work that already has an owner and an approval path:

• Listing and property Q&A: answer buyer, agent and staff questions from listing and disclosure documents.
• Due diligence search: surface risks and clauses across title, survey and inspection files.
• Lease abstraction: pull key terms, options and obligations from leases.
• Market report summaries: turn long market and research reports into cited answers.

Each use case is retrieval-first: the model answers from your documents and shows where the answer came from.

Architecture: retrieval first, agents second

A workable stack is small: an ingestion pipeline that chunks and embeds approved documents, a vector store you control, and a chat call that receives the top matches as context. Plugsky embeddings and chat completions are OpenAI-compatible, so the glue code is familiar to any team that has used the OpenAI SDK.

Add function calling only after retrieval is trustworthy. Agents can then request data from CRM, listing and transaction systems through your own APIs, with the model choosing the call and your service enforcing permissions.

Residency, access and auditability

Real estate data is sensitive. Plugsky supports cloud, VPC, on-prem and air-gapped deployments, with region selection for residency requirements. Air-gapped installations keep prompts and documents inside your network entirely.

Use scoped API keys per application, rotate them on a schedule, and log requests and responses under your retention policy. Keep client and counterparty data scoped per deal, and require citations for any answer used in a transaction.

A rollout plan that stays explainable

Pick one document class, build a fifty-question evaluation set with known answers, and measure retrieval hit rate and answer accuracy before expanding. Publish the assistant to one team, collect the questions it could not answer, and close those gaps by adding documents rather than prompts. Require citations for any answer used in a transaction and keep client data scoped per deal. Keep every answer traceable to a source.

Frequently asked questions

Can our data stay inside our own network?

Yes. Plugsky supports VPC, on-prem and air-gapped deployments, so prompts, documents and embeddings remain inside your environment when required.

Does Plugsky train on our documents?

For strict requirements, choose a private or air-gapped deployment so content stays inside your environment. Review the current data-handling terms and DPA for cloud plans before rollout.

How do citations work?

Your retrieval layer passes the top matching chunks into the chat call, and the assistant returns answers with references to those chunks. Require a refusal when no source clears the relevance threshold.

Which model should we use for leases and due-diligence files?

Benchmark a long-context model against chunked RAG on your own questions. Long-context helps with whole-document reasoning; RAG is cheaper and easier to cite.

Is there a free way to evaluate this?

Yes. The free plan includes two free AI models with no card, and the 14-day full-access trial lets you test larger models on your documents.

Can it handle per-deal confidentiality?

Yes. Segment indexes per deal or client and use scoped API keys; for sensitive mandates, keep everything inside a private, on-prem or air-gapped deployment.

Can it read title documents and surveys?

Scanned documents need OCR first, since vision endpoints are coming soon. Embed the extracted text and keep the original file linked to the answer.
