The thumb up ("upvote") and thumb down ("downvote") buttons next to your Replika’s messages help you give feedback about these messages.
You may choose to upvote if you think that this response is relevant to what you said or just funny. You may also choose to downvote if you don't like this response.
It takes time to process upvotes and downvotes data and improve the conversation flow. However, this data has a great long-term impact on the conversation's quality. Feel free to use these buttons as much as you want!
