Turn WaniKani mnemonics into AI-generated memory images
Generate a picture of the mnemonic story from a button on the WaniKani lesson or reference page, without leaving the site.
The extension injects images into your normal lessons and kanji/vocabulary reference pages rather than sending you to a separate app.
Pairs each kanji meaning and reading with an image, giving you a second association channel beyond the written story.
Usable whenever you study new items or revisit reference pages to reinforce older ones.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
