Microsoft's AI assistant integrated across Office 365, Teams, and Edge. Can summarize documents in Word and Excel, but lacks structured lease extraction, confidence scoring, and CRE-specific intelligence.
Lextract wins 9 of 10 feature categories
Based on features, pricing, and workflow integration
Microsoft Copilot is embedded across the Office 365 suite - Word, Excel, Outlook, Teams - making it the most accessible AI tool for professionals who already work in Microsoft's ecosystem. Open a lease in Word, ask Copilot to summarize it, and you get a reasonable overview within seconds. For teams that live in Excel and Word, the appeal is obvious: no new tool to learn, no new login, no context switching.
But Copilot is a productivity assistant, not an extraction engine. It can summarize a lease in natural language but cannot extract 126 structured fields into a consistent schema, score confidence on each value, detect red flags against CRE-specific rules, or produce output that imports directly into a property management system. For individual document questions it works well. For structured lease abstraction at portfolio scale, it creates more manual cleanup work than it saves.

$15 for a single lease extraction. Volume pricing: $65 for 5 leases ($13 each) and $120 for 10 leases ($12 each). No subscription.
Copilot Pro costs $30/user/month in addition to the Microsoft 365 subscription ($12.50-$22/user/month for business plans). Enterprise Copilot starts at $30/user/month bundled with E3/E5 plans. The AI functionality is a subscription add-on, not a standalone product.
Microsoft Copilot costs $30/user/month on top of an existing Microsoft 365 subscription. For a team of 3, that is $65/month - equivalent to 4.5 Lextract 10-pack lease credits per month. If your team abstracts more than a few leases per month, the per-lease cost of Copilot (subscription + labor for manual reformatting) significantly exceeds Lextract's $15 flat rate. Copilot's value is in general Office productivity, not in lease abstraction specifically.
CRE professionals who need structured, repeatable lease data for portfolio management, due diligence, and PMS integration - where output consistency and confidence scoring are essential.
Teams that need general AI assistance across their entire Office 365 workflow - document drafting, email summarization, Excel analysis - and occasionally want quick lease summaries without leaving their current application.
Lextract is the stronger choice for structured lease abstraction. Microsoft Copilot may make sense for teams who need general Office 365 productivity assistance and occasionally want a quick lease summary within Word or Outlook -- but for the majority of CRE professionals who need structured data from multiple leases, Copilot produces summaries, not structured data.
It cannot extract 126 fields into a consistent schema, cannot score confidence per field, has no CRE-specific red flag detection, and has no export pathway into property management systems. Lextract costs $15 per lease with no monthly commitment and delivers structured, auditable output ready for your systems. Use Copilot for Office productivity. Use Lextract when you need lease data you can actually operationalize.
