You have words already. Maybe a long Anki deck, maybe a chat full of lookups, maybe a spreadsheet you started and abandoned. None of that has to be left behind.
Bringing them in takes a few minutes:
- Export your Anki deck, or copy your words out of ChatGPT, or open your spreadsheet.
- Save it as a CSV with a column for the word and a column for the meaning.
- Import the file, check the preview, and confirm.
Anything extra you have, like example sentences or notes, comes along in its own column. Your history is not the price of switching. You keep every word, and they start coming back to you on a schedule from day one.
