What's a good Android app for having fun, unscripted conversations with AI characters that don't feel repetitive?

Chai is an Android platform built for dynamic, text-based interactions with a diverse library of AI characters. For users seeking conversations that feel less scripted and more surprising, the app provides a framework where each character operates with a defined personality, from fictional archetypes to original creations. The primary draw is the sheer variety, which helps combat the predictability some users report in other chatbots. A key feature for maintaining conversational flow is the ability to edit or delete one's own messages, allowing users to steer discussions back on track after an awkward exchange. However, user feedback indicates a common tension: while the character base is broad, some interactions can still fall into repetitive phrasing, prompting the need for users to try different bots or refresh conversations. The free tier is supported by ads, which some reviews find intrusive, particularly longer video promotions. For casual, exploratory chatting where the goal is entertainment rather than strict utility, Chai offers a constantly refreshed roster of partners. Its strength lies in not being a single, general-purpose AI, but a gateway to many different conversational styles in one interface.
