Heartbits
Chat and roleplay with AI characters you create
About Heartbits
Heartbits is a character chat platform. You create AI characters, hold ongoing conversations with them, and play through interactive stories, with the site naming romance, mystery and fantasy as its main genres alongside a short-form format it calls microdramas. Both realistic and anime visual styles are offered.
This is a large and fast-moving category that tends to be described in terms of the technology rather than what people use it for. In practice the draw is persistent characters: a conversation that remembers what happened last time, with someone whose personality you defined. That is closer to collaborative fiction than to a chatbot, and it is why the genre framing on the site is a more honest description of the product than any feature list would be.
Worth knowing before you evaluate it: no pricing is published without an account. The submission described it as freemium and the site is free to begin, but the tiers are behind sign-in, so what the paid plans cost and what they unlock is not something we can state from the outside.
You either pick a character from the existing library or create your own, defining who they are and how they speak. The creation step is what separates this from talking to a general assistant.
You chat or roleplay in an ongoing conversation. Continuity across sessions is the point, so the character carries what has already happened rather than starting fresh.
Interactive stories give the conversation a frame: a scenario with a direction, rather than an open-ended exchange with no shape to it.
Microdramas are the short-form version, which suits a reader who wants a contained episode instead of an indefinite thread.

People who enjoy collaborative fiction and want a partner for it that is available at three in the morning. The genre focus makes the audience clear: this is entertainment, and it is honest about being entertainment rather than dressing itself up as a productivity tool.
Writers occasionally use character chat to test dialogue and voice before committing a character to a manuscript, which is a legitimate if secondary use.
It is not an assistant and will not help you with work. And since the plans sit behind sign-in, budget an account creation into evaluating it, because you cannot compare the cost against anything else until you do.
