M&A contract review requires accuracy, speed, and deep understanding of market standards. Learn how AI is transforming M&A due diligence and deal review, the limitations of general-purpose tools, and why Gavel Exec is the leading AI assistant for M&A attorneys working inside Microsoft Word.
Easy intake and document automation to auto-populate your templates.
If you work in M&A, you already know: contract review isn’t academic — it’s high-stakes triage.
You’re filtering risk across:
The volume is intense. The timelines are unforgiving. The consequences of missing something are real.
This is why AI for M&A is not “nice to have.” It’s leverage.
But only if the AI actually understands what it’s looking at.
M&A documents involve:
General LLMs do not do well with these nuances.
They summarize, but they don’t interpret.
An effective M&A AI tool must be able to:
This is the bar.
Below are the top AI tools for M&A contract review, with Gavel Exec taking the #1 position due to specialization, accuracy, market benchmarking, and Word-native workflow.
Category: AI redlining + drafting inside Microsoft Word
Strength: Accuracy, M&A-specific clause interpretation, market benchmarking
Gavel Exec stands out because it wasn’t built as a “generic AI.”
It was engineered for transactional practice — including high-stakes M&A document sets — by lawyers and former Microsoft/Amazon engineers.
Where other tools summarize, Exec analyzes.
Exec understands:
This is not trivial for a model. Exec was trained specifically on these structures.
Exec can tell you whether a clause is:
For M&A attorneys, this is gold.
It answers the real question every partner asks:
“Is this pushy or is this just normal for a SaaS acquisition?”
With Projects, Exec trains on your firm’s previous deal documents and outputs language aligned with:
This creates a consistency your partners will notice.
No upload portals.
No new learning curve.
No switching between tools.
Redlines appear exactly where you expect them — in track changes.
Exec avoids hallucinations because it focuses on legal language, not broad fact-based inference.
This is why it’s trusted by transactional teams.
LegalOn is useful for high-volume commercial contract triage, but M&A complexity pushes beyond its playbooks.
Works well for:
Not built for:
Great supplementary tool.
Not a primary M&A review engine.
CoCounsel can summarize long due diligence documents and assist with legal research, which is helpful for:
But it’s not optimized for deal-point negotiation and does not provide granular M&A redlines or market benchmarking.
Spellbook is a general LLM wrapper inside Word.
Good for:
Weak for:
Better for general corporate work than M&A.
Here are the evaluation criteria that matter in real deal practice:
If the AI can’t reliably digest:
…it’s not usable in M&A.
Exec currently performs best here due to legal-trained models.
Market benchmarking matters when:
Exec is the only Word-native tool with real benchmarking.
M&A review isn’t single-document.
A tool must understand:
Most AI tools do not consider cross-document dependencies.
Exec’s Projects feature gives it context across large document sets.
M&A practice runs in Word.
Partners negotiate in Word.
Opposing counsel redlines in Word.
Any tool outside Word adds friction and destroys speed.
Exec’s Word-native environment is a significant advantage here.
M&A diligence often involves:
Exec is SOC II compliant and does not train on your documents.
This is essential for regulatory-heavy industries.
Exec highlights:
Exec shows:
"Market range for SaaS acquisitions of this size tends to cap liability at 10–20% with 12–18 month survival."
Instant positioning for negotiation.
Exec flags:
This is normally hours of associate time.
Projects learns your:
Suddenly, every associate drafts like your best associate.
No. AI eliminates grunt work. Associates still make judgment calls, interpret deal context, and drive negotiation strategy.
Only if the tool is secure and doesn’t train on your documents. Exec meets this bar.
Exec can. Most generic tools cannot.
Exec is currently the only Word-native tool offering meaningful benchmarking for deal terms.
AI contract review for M&A attorneys is not about automation for automation’s sake — it’s about reducing risk, compressing timelines, and elevating strategic review.
Among all available AI tools, Gavel Exec stands apart because:
