What is Translation Cache?

Stored machine translation results served on subsequent requests, eliminating repeat API calls and their cost.

In more depth

Cache-first translation is why a BYO-key site costs cents after the first pass: only never-seen strings reach the API.

Why it matters for your website

Understanding Translation Cache helps you make better decisions when taking a WordPress site multilingual — from choosing URL structures and engines to controlling costs. Transxlate handles the mechanics (language URLs, lang attributes, caching, hreflang on Pro) so terms like this become settings, not engineering projects.
