What Linguae does

Linguae reads the structure: tables, columns, and paragraphs, then rebuilds it in the target language. The output is a copy of the original, just translated.

Why Linguae exists

Most translation tools lose it the moment you paste. Tables collapse. Columns merge. Footnotes disappear. Linguae processes the structure, not just the text.

Copying, splitting, reformatting. It takes days. Linguae runs the whole document in minutes. A 300-page book in 10 minutes, layout intact.

No cloud. No upload. No third party sees your files by default. Translation models run locally after the initial download. You choose what stays private.

Three steps

No account. No setup. No complexity.

01

Drop

Drag your PDF, DOCX, or PPTX into Linguae.
