The dealbreaker
If your practice doesn't have document-heavy workflows (discovery, due diligence), CoCounsel's per-module pricing won't pay for itself.
Our review
CoCounsel handled a 2,000-document discovery set that would've taken a paralegal a week — it organized the facts, flagged key evidence, and drafted a memo. For litigation-heavy firms it's transformative; for everyone else the pricing is a wall.
