When it comes to expressing your opinion or adding your two cents to a discussion, there are various ways to do so. Instead of using the phrase "chime in with," which can become repetitive or overused, consider these synonyms: join in, interject, add, contribute, remark, comment, share, speak up, weigh in, and offer input. Each of these phrases conveys the idea of actively participating in a conversation or discussion, and can help you avoid using the same expression repeatedly. Experimenting with different phrases can also help you distinguish between different types of contributions, such as expressing agreement or disagreement or sharing personal experiences.
