About Gleaner
Gleaner helps you learn English while you browse.
Select a word, phrase, or sentence on any page. Gleaner looks up a short definition, lets you save it with the page context, and keeps everything in a side panel for later review. You can export cards to Anki when you are ready.
What you can do
• Save words, phrases, and sentences from the page you are reading
• See English definitions, phonetics, examples, and origin when available
• Show a native gloss for Chinese, Japanese, or Korean browser languages (downloaded once to your device)
• Review and search your cards in the side panel
• Export to Anki, including audio for word cards when available
• Optionally sign in with Google to sync cards across devices
Privacy
Gleaner stores your cards on your device by default. Sign-in and sync are optional. Dictionary lookups send only the selected text to lookup services. We do not sell your data.
