Building Legal Agents When You Can't See the Data - Jacob Lauritzen, CTO of Legora
在看不到数据的情况下构建法律智能体——Legora首席技术官Jacob Lauritzen
Legora CTO Jacob Lauritzen must build legal agents without seeing client data, forcing law firms to decide how much auditability they will trade for a closed assistant's convenience.
Judgment
Law firm CIOs and general counsel must decide whether to accept Legora’s paraphrased traces, not raw client-data traces, as sufficient audit evidence; choosing the closed assistant buys convenience but caps independent verification at what the firm can reconstruct.
Basis
Jacob Lauritzen, CTO of Legora, says the company “can’t read a single trace” of what its agent does for a lawyer because the data belongs to the law firm’s clients. Legora’s workaround is to build test environments modeled on customers’ work with three engineers and three lawyers, paraphrase traces, and narrow failures to 10 or 20 types. He also estimates models do about 60% of legal work well and cites a release that took citation accuracy from 70% to 99% without Legora changing anything. The mechanism: privacy forces the vendor to validate behavior through simulated worlds and aggregated failure categories, so the law firm’s own audit process becomes the outer check on a closed assistant.

Unclear The source does not say what trace retention, client consent, or audit rights Legora’s contracts actually give law firms.
