Yonder — Inline Currency, Unit & Time Zone Converter

About

Ever hit a price in the wrong currency, a distance in the wrong units, or a meeting time in the wrong zone — and had to stop and open a converter? Yonder does it in place.

Highlight any price, measurement, or time on any web page and Yonder pops a tiny card with the converted value — in your currency, your unit system, and your time zone. Click any result to copy it. That's the whole thing.

★ WHAT IT CONVERTS
• Currencies — 150+, with live daily exchange rates. "$50" → €46 · £39 · ¥7,340
• Time zones — "3pm PST" → your local time, plus any cities you add. DST-aware.
• Length, weight, temperature, speed, volume — "10 km" → 6.21 mi, "72°F" → 22.2 °C, "1.5 kg" → 3.31 lb.
• Metric ⇄ imperial, both directions, using your browser's own Intl engine.

★ SMART PARSING
Yonder reads the messy real world: symbols before or after the number ($50, 50€, ₹1,499), ISO codes (50 USD, EUR 1200), both decimal conventions (1,200.50 and 1.200,50), magnitude suffixes ($1.5k, 2M), and times with or without zones (3pm PST, 15:00 UTC, noon).

★ PRIVATE BY DESIGN
The content of the pages you visit is never read or transmitted — Yonder only looks at the text you select, and only to convert it. There is no account, no history access, no tracking, and no analytics. Currency is the one feature that touches the network, fetching a daily rate table from open.er-api.com (no API key). A bundled rate snapshot ships inside the extension, so conversions still work fully offline — just slightly out of date. Units and time zones are 100% local math.

★ 13 LANGUAGES
The whole interface is translated: English, Español, Français, Deutsch, Português, Italiano, Nederlands, Русский, 日本語, 中文, 한국어, العربية (RTL-aware), and हिन्दी.

★ FEATHERWEIGHT
Vanilla JavaScript, no frameworks, no build step, no background chatter. Just highlight and go.
