Product summary
Review the store description, core capabilities, and common use cases.
Defog automatically replaces text on every webpage you visit. Map UUIDs, IDs, hashes, codes, or any text pattern to a human-readable label — and never squint at a raw identifier again.
Create a mapping once, and Defog replaces every occurrence across every site you visit. Replacements survive page navigation, dynamic content updates, and single-page app re-renders.
Your data never leaves your browser. All mappings are stored locally. Fully open source: https://github.com/ayoung19/defog-extension
