Lantyer criteria for evaluating legal AI tools
A fundamental checklist before legal teams approve or procure a new AI solution.
1. Real purpose of the tool
What does the AI actually do, and what is only marketing language?
2. Data processed
What client, case, contract or business information will the tool read?
3. Retention and training policy
Can the vendor use your documents to improve models or datasets?
4. Location and transfer
Where is the data processed, and is international transfer involved?
5. Access controls
Who at the vendor can access uploaded or generated material?
6. Explainability
Does the AI show legal sources or produce black-box conclusions?
7. Hallucination risk
Are there guardrails against invented cases, statutes or citations?
8. Integration
Can it connect safely to existing document, matter or knowledge systems?
9. Professional responsibility
Does the workflow require human legal review before external use?
10. Cost and dependency
