'Auswendig' (by heart) is most commonly combined with the verb 'lernen' (to learn). Other typical verbs are 'können' (to know/be able to), 'wissen' (to know), 'kennen' (to know), or 'aufsagen' (to recite).
Kannst du das Gedicht schon auswendig?
Do you already know the poem by heart?
As an adverb, 'auswendig' (by heart) usually stands at the end of a sentence or clause, directly before the conjugated verb or the past participle.
Sie hat ihre Präsentation komplett auswendig gelernt.
She learned her presentation completely by heart.
People typically learn things by heart that have a fixed form, such as 'ein Gedicht' (a poem), 'einen Text' (a text), 'Vokabeln' (vocabulary), 'eine Formel' (a formula), or 'eine Telefonnummer' (a telephone number).
Ich kenne ihre Telefonnummer nicht auswendig.
