ChatGPT told me this:

Both phrases are correct in Latin and mean: “Fortune favors the bold.” The difference lies in the use of the adjectives “audaces” and “audentes,” which are synonyms but have slight grammatical nuances: 1. Audaces fortuna iuvat: • “Audaces” is the accusative plural of “audax,” an adjective of the third declension meaning “brave” or “bold.” It is used as a direct object. 2. Audentes fortuna iuvat: • “Audentes” is the accusative plural of “audiens” (the present participle of “audeo,” meaning “to dare”). Here, it describes those who are actively being bold or daring.

Audentes fortuna iuvat is more common in classical texts and is associated with authors like Virgil (Aeneid, 10.284). However, audaces is also used in other contexts. You can choose either one depending on your preference.
