Experience one useful part

Less guessing.
More trying.

Start in the browser. The free previews show a limited part of the workflow; they do not claim to be the complete desktop applications.

SOURCE + TARGET TEXT

Is a placeholder missing?

One source/target text pair. Named and printf placeholder counts and argument-type order only. No files, CSV import, project history or AI.

The premium workflow

From a finding
to a review record.

The planned desktop licenses add projects for your own supported files, review history, exports and backups. Your decisions stay connected to evidence. Optional AI never replaces approval by a qualified reviewer.

Technical privacy overview

Your work stays local.
AI is a separate choice.

The desktop apps store snapshots, projects and review history locally. Core checks do not require cloud AI. License activation/validation contacts the licensing service when used. Optional AI sends the exact request you preview and approve; the API provider's policies apply.

Product-information pages use no executable JavaScript. The separate free preview tools use only first-party browser code, with no analytics, cookies, storage or network submission. Text in the placeholder checker stays in page memory until cleared or closed. Host request metadata and emails you choose to send may still be processed. This overview is not a finalized sales policy.
