Public Beta is Live

Continuous localization from your terminal.

Forthwith detects changed strings, translates only what's new, validates placeholders, plurals, and markup, then writes clean localization diffs back to your repo.

Founding Beta Pricing: 20% off through June 30, 2026.

Not just translation. Localization maintenance.

LLMs can translate a string. The hard part is keeping every language in sync as your app changes without breaking resource files.

Scans projects and detects localizable resource files

Discovers new or changed strings and leaves unchanged text alone

Validates and can auto-correct localization-safety issues

Runs from the terminal in Git workflows, including older projects

One repeatable CLI workflow

Run the same commands for the first pass and for every localization update after it.

1

Initialize

Run Forthwith in your project. It scans the codebase, detects localizable resource files, and learns the file formats it will maintain.

$ forthwith init
2

Translate

Forthwith compares your source strings, finds new or changed entries, and translates only those updates on your approval.

$ forthwith translate
3

Review

Validated localization files are written back into your repo. Review the clean Git diff, test it, and commit when ready.

$ git add . && git commit
