Shipping log

Changelog

PrivBatch is a young project. First tools shipped early May 2026, public launch on Wed May 27. Built solo, iteratively, with Claude Code as a coding assistant. Each tool was hand-tested for the privacy claim before shipping - the privacy audit page walks through how to verify it yourself. Updates land weekly.

Coming next

What's on the build list

Tool Chaining Pipeline Builder - visual drag-and-drop pipeline editor (CSV → JSON → Anonymise → Download). Pro Business feature.
Smart Agent - auto-detection for batch jobs. Auto-detects file structure, suggests transformations, writes JSONPath queries, and applies bulk operations across hundreds of files. Pro Business feature.
Light-mode redesign - the current light mode works but visual cohesion needs a refresh.
