We needed a pan-India stamp-duty engine and the Atherna team delivered it in four days. The regulator integrations have transformed our compliance work, and unlike every other legal AI we tried, it never cites repealed circulars.
Atherna has been invaluable in our work. The research is best-in-class of every tool I've tried, and the team is genuinely a joy to work with.
I can put an entire arbitration record into it and reason across all of it. Nothing else I've used holds up at that volume without losing the thread.
