What is the best AI tool for due diligence in 2026?
Harvey AI leads for legal due diligence. It handles high-volume contract review, extracts risk clauses, and surfaces anomalies across massive document sets — exactly what M&A, PE, and in-house legal teams need when the data room opens.
Can AI replace human lawyers in due diligence?
No — and that's the wrong question. AI eliminates the 80% of grunt work: reading, tagging, flagging. Your lawyers focus on judgment calls. Teams using Harvey AI report reviewing 10x more documents without adding headcount. The risk isn't replacing lawyers — it's competing against firms that use AI while you don't.
How does Harvey AI compare to Ironclad for due diligence?
Harvey AI is built for unstructured legal analysis — reading contracts, identifying risk, answering legal questions across documents. Ironclad excels at structured CLM workflows: tracking obligations, managing negotiations, enforcing playbooks. For a live M&A data room, Harvey wins. For ongoing contract governance post-deal, Ironclad picks up the relay.
What AI tools help with knowledge management during due diligence?
Glean connects fragmented internal knowledge — prior deal memos, past diligence reports, internal research — so your team stops reinventing the wheel on every transaction. It won't read the target's contracts, but it ensures institutional knowledge surfaces when it matters. Pair it with Harvey AI for full coverage.
