Ship localized apps without breaking production strings.

You can, and for simple projects that may be enough. Forthwith is designed for repeatable localization runs where the tool discovers strings, translates only what changed, validates fragile syntax, and writes clean updates back to your existing localization files.

Xcode localization agents are a strong option when your workflow lives entirely in Apple's toolchain. Forthwith is built for repositories that span stacks: one CLI command detects only new and changed strings, translates them, validates placeholders, plural forms, and output structure, then writes reviewable updates across iOS, Android, Flutter, React Native, React, Phoenix, and go-i18n. The difference is not simply AI translation—it is a maintained, repeatable localization pipeline you can run the same way across supported projects.

Forthwith validates framework-specific placeholders and interpolation tokens, required plural forms, missing keys, array lengths, and structured translation output. The resulting diff stays reviewable.

Not necessarily. Generate translations quickly, prepare reviewable diffs, and reduce mechanical errors before human review or release.

Usage is measured by the source words processed for translation, including prompt text. Adding target languages increases total words processed, but billing remains based on words in.

No. Forthwith compares source strings and only sends new or changed entries for translation.

Forthwith is in public beta while framework support, validation rules, and the developer workflow are refined. Early users get discounted pricing and can help shape the product.
