AI for real estate agents.
Custom integrations built around your existing data.
Solo agents, small teams (2–10 agents), and boutique brokerages — typically running on a CRM (Follow Up Boss, kvCORE, Wise Agent), MLS access, and a constant flow of leads, listings, and transactions across multiple stages.
What's different about AI for real estate agents.
Real estate is a relationship business that runs on data: every lead has a stage, every listing has a timeline, every transaction has 47 documents. Solo agents and small teams lose 10+ hours per week to administrative work that AI absorbs cleanly: drafting listing descriptions, summarizing comps, writing follow-up emails, formatting CMAs, building the listing presentation. Mainsail builds integrations that connect the agent's existing tools (CRM, MLS, drive) to Claude so the agent stops being a typist and gets back to the part of the job that compounds — being in front of clients.
The busywork patterns most real estate agents firms run on.
MLS data + photos in, polished MLS-compliant description out. Tweak voice and post — 20 minutes saved per listing.
Pull comps from MLS, structure them in your CMA template, and draft the buyer-facing narrative that explains the recommended list price.
AI drafts the next message in every lead's nurture sequence based on their stage and last interaction; agent reviews and sends one batch per day.
Document checklist tracking, missing-doc reminders to clients, draft of the next required communication — the TC stops chasing.
Monthly neighborhood-specific market updates, drafted in your voice, branded with your photo, ready to send to the past-client database.
Open house attendees scanned in via QR; AI drafts the personalized follow-up to each one within 4 hours of close.
Concrete examples, not abstract capabilities.
Follow Up Boss, kvCORE, Wise Agent, BoomTown — natural-language queries and auto-drafted next-touch messages across the entire database.
Pull live comps via MLS feed; structure into your branded CMA template; draft the buyer/seller narrative.
Photos + MLS data + your voice in. Compliance-checked listing description out, ready to post.
Annual home-anniversary, market-update, and life-event touches drafted automatically; agent approves and sends.
DocuSign + dotloop + Skyslope — auto-flag missing initials, draft chase emails to the buyer agent or coordinator.
Where real estate agents' data already lives.
- → Follow Up Boss / kvCORE / BoomTown / Wise Agent (CRM)
- → MLS feed (RETS / RESO Web API)
- → DocuSign / dotloop / Skyslope (transaction docs)
- → Email inboxes (lead inquiries, agent communications)
- → Photo libraries (listing photos, drone shoots)
- → Past-client database (Excel, CRM contacts)
Don't see your specific software? It's almost certainly integratable. Bring the list to the discovery call and we'll tell you what's possible.
A specific moment, not a marketing claim.
Tuesday morning, an agent asks: 'who in my database is most likely to need to move in the next 6 months, based on what I know about them?' Forty-five seconds later: a ranked list of 12 people with the specific signal that triggered each (kid's college start date, lease renewal, last conversation about job change). The agent calls the top three before noon. One becomes a listing.
Build fee + monthly retainer. Both transparent.
Real estate integrations typically run $600–$2,000/mo for solo agents and small teams. The ROI math is brutal: one extra closed transaction per quarter ($8K+ commission) covers the integration for a year.
We don't mark up API usage. The retainer covers Mainsail's work — building, maintaining, and expanding the integration. You see the actual Anthropic / OpenAI usage in your monthly summary. See the full pricing model →

What does a Mainsail AI integration cost for real estate agents?
Real estate integrations typically run $600–$2,000/mo for solo agents and small teams. The ROI math is brutal: one extra closed transaction per quarter ($8K+ commission) covers the integration for a year. The build fee is one-time; the monthly retainer covers AI API usage (passed through at cost), ongoing maintenance, and new use cases as they come up. No long-term contract — month-to-month after the first month.
-
Which real estate agents software does Mainsail integrate with?
Most of the systems real estate agents already use have APIs that work cleanly with Claude. Common integrations include: Follow Up Boss / kvCORE / BoomTown / Wise Agent (CRM), MLS feed (RETS / RESO Web API), DocuSign / dotloop / Skyslope (transaction docs), Email inboxes (lead inquiries, agent communications), Photo libraries (listing photos, drone shoots), Past-client database (Excel, CRM contacts). If a tool doesn't have an API but does have data exports (CSV, scheduled reports), we build a slightly different ingestion layer. The only hard 'no' is software that contractually forbids automated access.
-
Is my data safe? What stops the AI from being trained on it?
Anthropic's API doesn't train on data submitted via their business tier — it's contractually excluded. Same for OpenAI's enterprise tier. Mainsail builds integrations that route through these enterprise APIs only. Your data is never used to train the underlying model, never shared between accounts, and lives in your authorized workspace only. We document the data flow in the engagement brief so you know exactly what's accessed.
-
How fast does the first integration ship?
Discovery call → scoping doc → 2–3 weeks of build → live in your team's hands. Most clients see real time savings within the first month. Compounding wins (the team finds new ways to use the assistant, you add more data sources) typically show up in months 2–4.
-
What if I want to start small?
That's how most projects start. Pick the single highest-friction workflow in your business — the thing costing your team the most hours per week — and we build the integration just for that. Usually 2–3 weeks, $1,500–$3,000 one-time, $400–$1,200/mo recurring. If it earns its keep, expand. If it doesn't, you can stop after the first month with no further commitment.
Independent CPA firms, small accounting practices, and bookkeeping shops — typically 1–15 staff serving small-business clients across local industries.
General contractors, mechanical contractors, electrical, plumbing, and specialty trades — typically 5–50 employees running multiple active job sites with crews, subs, and a constant flow of bids, change orders, and invoices.
Independent restaurants, small chains (2–8 locations), and food-service operators — typically running on Toast or Square POS with limited back-office staff and zero appetite for software they have to manage themselves.
Independent property management companies serving 50–500 units of residential or small commercial — typically running on Buildium, AppFolio, or Propertyware with a tenant base, an owner base, and a maintenance crew.
