Migration Path
Many teams transition from offshore to AI:
- Start: Use AI for acquisition DD (time-sensitive)
- Continue: Use offshore for non-urgent portfolio work
- Evaluate: Compare quality, cost, capability
- Optimize: Right tool for each use case
Frequently Asked Questions
Is AI as accurate as human abstractors?
AI platforms achieve high accuracy with consistent performance. DDee.ai adds citation tracking for instant verification—often more reliable than human work without source links.
What about unusual lease formats?
AI handles most formats well. Very unusual documents may benefit from human review, but this is increasingly rare.
Can I use both?
Yes. Many teams use DDee.ai for acquisition DD (speed-critical) and offshore for non-urgent portfolio projects.
What about multi-language portfolios?
NTrust supports 40 languages. Most AI platforms are English-focused. For global portfolios, consider hybrid approach.
