Standardise messy real-world columns automatically.
Company names spelled six ways, addresses in four formats, job titles with no convention. The AI cleaner proposes a canonical form for each cluster of values, shows you the mapping, and applies only the changes you approve.

Common problems and fixes
Two genuinely different companies were clustered together.
Split the cluster in the review panel and raise the similarity threshold before re-running.
Clustering is slow on a large column.
Deduplicate distinct values first — clustering runs on unique values, so a column with few distinct entries is fast regardless of row count.
