proofd

A terminal UI proofreader powered by Claude. Paste your text, pick an audience and model, and get back three tone variants (concise, polished, verbose) with corrected spelling, grammar, and technical terminology. The polished variant is auto-copied to your clipboard.

Built for data/analytics engineers -- it understands terms like ETL, dbt, medallion architecture, and more.
