Engineering & Validation

Engineered. Tested. Validated.

SlangBit has been tested across real Windows workflows, desktop applications, browsers, email clients, social platforms, source code, long documents, HTML content and offline environments.

An extensive certification-related investigation led to additional stress testing, edge-case analysis, input hardening and the successful completion of Microsoft Store certification.

25,000+ Characters processed during long-form translation testing.
REAL WORKFLOWS Validated across browsers, Office software, email, social platforms, development tools and Windows applications.
EDGE-CASE HARDENED Unusual input representations were investigated, reproduced and resolved through additional input normalization.
STORE CERTIFIED Successfully completed Microsoft Store certification for Windows distribution.

Private by design.

SlangBit does not send translated text to Memmola Labs or to third-party translation services. Once a language package is installed, translation runs locally on your Windows computer.

NO CLOUD TRANSLATION
FAQ

Common questions.

Does SlangBit need internet?

Only to download language packages or open documentation. Translation itself runs locally after packages are installed.

Does SlangBit collect text?

No. SlangBit processes copied text locally and does not send it to Memmola Labs or cloud translation APIs.

Which Windows apps are supported?

SlangBit works with most applications where text can be copied and pasted, including browsers, editors, email clients and office software.

Are language packages included?

Language packages are managed separately through the Package Manager, so users can install only the languages they need.
