Show HN: One-Click CSV Deduplication (open-source)

I made an app to fuzzy-deduplicate my Google Sheets and CRM records

- No manual configuration required - Works out-of-the-box on most data types (ex. people, companies, product catalog)

Implementation details:

- Embeds records using an E5 model - Performs similarity search using DuckDB w/ vector similarity extension - Does last-mile comparison and merges duplicates using Claude
