To get formatted information (like conjugation charts) from a website onto your Anki flashcards, we don't recommend copying the text; we recommend taking a screen-grab/shot.

Note: As of September 12th 2019, we no longer provide official support for our Anki based pronunciation trainers and word lists. You are more than welcome to still purchase and use them, but the support we are able to offer for these products is limited. For supported languages, these materials are already built into the Fluent Forever app.
