Frequently asked

Will AI cleaning preserve data integrity?
For clear cases (typos, format inconsistency), yes - AI is more consistent than manual cleaning. For ambiguous cases (which duplicate to keep, how to impute missing), AI guesses; spot-check critical decisions.
Julius vs Formula Bot?
Julius is conversational with stronger context retention across cleaning steps. Formula Bot is one-shot for individual cleaning operations. For multi-step cleaning, Julius; for quick ad-hoc, Formula Bot.
Is AI cleaning safe for PII?
Cloud tools send data to vendor servers. For PII or regulated data, use Deepnote with VPC deploy or self-host options, or scrub PII before AI cleaning.
