StringSmith Pro

StringSmith Pro is a game localization QA tool for game developers. Import your string tables and catch the bugs players screenshot — before they ever ship.

Catch the bugs that break your localization:

- Placeholder mismatches across printf, {0}, {name}, and $var conventions

- Text-overflow prediction with per-language width modeling

- Missing and extra keys

- Mojibake and control characters

- French non-breaking-space rules

- German all-caps and compound overflow risks

- RTL markers

Preview problems before translators deliver: the pseudo-localization generator shows you where text will overflow, and per-language UI mock previews show the breakage.

StringSmith Pro includes:

- Unlimited languages and strings

- Pseudo-localization generator

- Per-language UI mock previews

- Markdown + CSV exporters
