When you gain this feat, you gain the following benefits:

• (Cleric, Druid, Paladin) You may choose a number of spells from your spell list of any level you can cast equal to half your spellcasting ability modifier, these spells become always prepared and do not affect the number of spells you can prepare.

• (Bard, Sorcerer, Warlock) You learn a number of additional spells equal to half your spell casting ability modifier and add them to your spell list. 

• (Wizard) You may choose a number of spells in your spellbook equal to half your spellcasting ability modifier, these spells become always prepared and do not affect the number of spells you can prepare.

You may take this feat multiple times gaining additional always prepared spells each time, however you may not take this feat if it would grant you more always prepared spells than the number you can prepare normally.
