About
Twelvefold means layers.
Twelvefold is the shared foundation for independent products: Localee for translating app localization files, Drafty for shaping rough writing into social posts, and Markwrite for reading and writing Markdown on macOS.
We are intentionally small. No all-in-one suite, no feature bloat. Each product is built to be the fastest way to solve one specific problem, then get out of the way.
Small by design
Three products, not thirty. We keep the surface area tight so each tool stays fast and finished.
AI-native
Models do the heavy lifting; the interface stays calm. You bring the intent, we handle the rest.
One standard
Different problems, same bar for craft. Every product ships from the same foundation.
Product questions
Clear answers for the work ahead.
What is Localee used for?
Localee is an AI translation tool for app localization files. Developers can upload JSON, YAML, Android XML, iOS strings, XLIFF, Flutter ARB, or Excel files, select target locales, and download translated files in the original format.
Can Localee translate JSON, YAML, XML, XLIFF, ARB, and Excel files?
Yes. Localee supports JSON, YAML, Android XML, iOS .strings, XLIFF, Flutter ARB, and Excel localization files. It is designed for format-preserving translation rather than copy-pasting strings into a general chat tool.
Does Localee preserve placeholders and file structure?
Yes. Localee protects placeholders such as {name}, {count}, %s, %1$s, %@, ICU MessageFormat, and inline HTML. It also preserves key order, nesting, comments, and the original file format so the output can be used as a drop-in localization file.
What does Drafty do?
Drafty turns rough writing into copy-ready social content. Paste a messy paragraph, bullet dump, voice-note transcript, or Notion draft, choose LinkedIn or X, and get a structured post or thread ready to copy and publish.
Can Drafty turn a rough draft into a LinkedIn post or X thread?
Yes. Drafty creates a hook and scannable structure for LinkedIn, or automatically splits a long draft into a numbered X thread with each post under 280 characters.
Does Drafty preserve my writing voice?
Drafty edits structure, emphasis, and readability while keeping the author's voice. It is a copy-from-draft writing assistant, not a tool that invents a post from an empty prompt.
Can I try Drafty without signing up?
Yes. Drafty can be started without a signup or credit card. Anonymous users get 5 polishes per day, and signed-in users get 10 per day; Pro adds unlimited polishes and priority processing.
