Swedeline

Learn Swedish while you browse: Swedeline swaps some words on English, German, French and Spanish pages for Swedish ones.

Learn Swedish while you read what you already read. Swedeline replaces a few words on English, German, French and Spanish web pages with their Swedish translation. You keep reading as usual, and the Swedish words slowly stick, in context, without a flashcard in sight. HOW IT WORKS • Swedish words appear inside running text with a soft yellow marker and a blue underline. • Hover a word to see the original, the Swedish base form with its gender (en bil, ett hus), and press 🔊 to hear it spoken with a Swedish voice from your system or browser. • Pick how many words get replaced with the slider (roughly 1–20 %). Changes apply live. • Turn Swedeline on or off for all sites or just the current one from the toolbar popup. You can also set a keyboard shortcut. DESIGNED NOT TO GET IN YOUR WAY • Only running text is touched: paragraphs and article bodies. Headings, menus, buttons, form fields, code and footers are left alone. • Ambiguous words, names and words that are also common verb forms are skipped, because precision beats coverage. • Swedish pages and other languages are left untouched. Language is detected automatically, per paragraph. • Works on single-page apps and infinite scroll. • Copying text or printing gives you the original words. PRIVATE BY DESIGN • No account, no API key, no AI service and no server. • The dictionaries ship with the extension, so it works offline. • Nothing you read ever leaves your browser. Swedeline collects no data. The interface is available in English, Swedish, German, French and Spanish. Translations are built from Wiktionary (via WikDict) and word-frequency data, licensed CC BY-SA. Source code (MIT): https://github.com/Gunneone/Swedeline
