Understand anything you read, in any language.
Select any word, sentence, or passage — Glozz instantly shows a translation and a context-aware explanation of what it actually means, right where you're reading.
Free to install — no API key, no setup. Every plan includes a daily usage allowance, and what you read is never logged or stored.
