“ようです” and “みたいです” are both used to express inference or judgment based on something the speaker has seen or heard. “ようです” is a slightly more formal expression and is commonly used in written language and polite conversation, while “みたいです” is more casual and is frequently used in everyday speech. Both “ようです” and “みたいです” are attached to the plain form of verbs and adjectives; however, note that their patterns of attachment differ in non-past affirmative sentences with nouns and na-adjectives.
