Mail Merge Studio Lite

A small, browser-only tool for creating personalized documents from a reusable template and recipient data.

Your document text and imported CSV data are processed in your browser. This app does not send them to an AI service or application server. Normal web-hosting access logs may still be recorded by the hosting provider.
