Editors' review
Finds what the contract does not say
The expensive problem in contract review is rarely a bad clause you read; it is a clause that is not there at all. Checking for absence is exactly the mechanical work a trained system does better than a tired reviewer at the end of the day.
Being grounded in Japanese contract practice is what distinguishes it from asking a general model. Advice drawn from US practice is confidently wrong about things like seal requirements and standard remedies.
It does not make the judgement call and does not pretend to. What it does is make sure the human judgement is applied to a complete picture.
Verdict
A real time-saver for in-house teams on Japanese contracts. Not a substitute for a lawyer.
