Profile notes
What to confirm before you sign
CoCounsel (Casetext) publishes 6 of the 8 fields in the Content Hub rubric. Across the 10 AI-native / Tech-enabled service vendors profiled here, the median is 6 of 8. The gaps below are not marks against the vendor — most of this industry quotes on request. They are simply the questions you still have to ask, and the answers are worth getting in writing before a file changes hands.
- What is the turnaround on a 1,000-page file, and is that a median or a best case?Ask what the clock starts from — receipt, or the point the file clears intake — and what the same number looks like in your busiest week.
- What formats does the deliverable come in, and do the citations survive export?Ask to see an exported file rather than a screen share. A citation that works inside the vendor's viewer and dies in Word is not a citation you can file.
- Where do the records live, and who signs the BAA?Protected health information is going to leave your office. Ask which entity holds it, in which country, and who is on the hook if it leaks.
- Is my data used to train a model?Ask for the answer in the contract rather than the sales call, and check whether it also binds their subprocessors.
