〜ようと思う・〜おうと思う

This grammar expresses a speaker’s intention or plan to do something in the near future. It combines the volitional or intention-form with と思う (I think) to indicate that the decision hasn’t been set in stone yet; it’s a plan or intention rather than a firm commitment. Use it for personal plans, reasonable predictions about your own actions, or when you are considering doing something but haven’t decided definitively yet. The form with 〜ようと思う is common for many verbs, while 〜おうと思う appears with some verbs that have an -おう volitional in their conjugation (e.g., 会おう, 买おう). In casual speech, this expression often conveys a flexible plan rather than a fixed schedule.
