DIRECT ANSWERS

Before this company buys AI.

01How many AI tools should a medium company legal services team start with?+

HubAI recommends 4 distinct tool roles for this scale. Start with the first workflow and add the remaining tools only when each removes a measured bottleneck.

02What should legal services measure during the pilot?+

Track accepted outputs, human correction time, complete-task cost, user adoption and any data or rights incident. Raw generation volume is not evidence of value.

03Should this company buy annual AI plans immediately?+

No. Avoid company-wide rollout, duplicated licences and integrations that have no monitored owner. Verify current pricing and contract terms directly with each provider before purchase.
