TemplateApp

Lazarus template application project with full localization. It took me quite some time to create a fully featured application project that could set the language from the system but also had the capability to set the language live from the application itself. Templating is good. It saves time because you don't have to reinvent the wheel and it prevents bugs because what you already have is probably already tested. See /help/index.html or the wiki page for further information.

Spintax Studio

Spintax Studio is a native Windows editor for spintax templates: two panes, your template on the left, its live render on the right. Preview and the valid/invalid verdict come from the real spintax engine inside the application, not from a second parser. Diagnostics carry line and column positions and link to the built-in help; panels list variable definitions, references, session values and #include targets with their resolution status. Generate variants locally, reproduce them with a seed, and export as plain text, an XLSX workbook, or one file per variant. Offline by default: no account, no telemetry, no Node.js, PHP or Python runtime — one self-contained executable. Optional AI drafting is off until you turn it on and talks only to the endpoint you configure, with your own key when it needs one. Interface and built-in help in 14 languages. Free and open source, GPL-3.0-or-later. The SPINTAX language and its engine family are documented at spintax.net.
