Non-cascading replacement

Apply many rules simultaneously without earlier replacements unexpectedly feeding later rules.

Literal and regex modes

Use straightforward text rules or slash-wrapped regular expressions with capture replacements.

Two-pane verification

Compare source and transformed text side by side with highlighting, line numbers, and character counts.

Portable configurations

Import, export, invert, and reuse named JSON rule sets without creating an account.

Privacy and offline operation

Your work remains yours.

Input, output, rules, configuration titles, and opened filenames stay in the page and are not persisted. Only interface preferences such as word wrap and scroll locking may be stored locally.

Ships as one readable HTML file with no runtime dependencies. The application works directly from file:// and requires no server, installation, or internet connection.
