Frontier's characters come from human-led visual novels, and what happens in the story becomes what they remember when you keep talking.

Choose PolyBuzz if you want over 20 million characters to browse and the freedom to build or import your own. Choose Frontier if you want a small set of human-led stories whose characters remember what you played through, and you accept that chat is metered in Quills.
Most character apps hand you a pile of user-made bots that nobody vetted. Quantity wins, craft loses. Personalities drift, the writing turns generic, and the slop piles up.
Frontier is a studio. Our stories are led by veteran writers with decades of experience and credits at studios you'd recognize, and a person signs off on everything that ships. That's the difference between a crafted world and an unmoderated feed, and it holds no matter what tools help along the way.
Veteran writers with decades of experience own each character's voice, backstory, and arc. It isn't a bot someone spun up in ten seconds.
Nothing ships unchecked. A person crafts and approves every story before it reaches you.
Quality over quantity: a hand-picked catalogue instead of an endless wall of unmoderated bots.
Frontier is the PolyBuzz alternative for readers who want characters with a story behind them. PolyBuzz says it hosts over 20 million characters, lets anyone create one, and describes its characters as purely AI-generated, operating without human oversight. Frontier's characters come from visual novels led by veteran writers, and a person signs off on each story before it ships.
Reviewers say people start looking for a PolyBuzz alternative when the character library, filters, memory or pricing stops matching what they want. PolyBuzz addresses memory itself: it states that its AI memory capacity is technically limited, so characters may forget previous conversations over time. At this review, its Basic and Premium memberships add stronger memory chat models and ad-free use. One App Store reviewer says half of what users used to do is now behind a paywall.
Frontier builds memory from the story. Authors mark which moments matter and how much, and those events carry across branches, chapters and sequels. The trade-off is scale and freedom: Frontier's catalogue is small and hand-picked, you cannot create your own characters, and chat messages and character photos cost Quills unless you are on the top plan.
How we compare: we write these breakdowns by hand, concede where a rival is genuinely stronger, and review the copy quarterly. No paid placements, no auto-generated filler.

Yes, if you want a character who remembers you and a story worth remembering. You unlock Frontier's characters by playing human-led visual novels, and the moments the author marks as important stay with them across chapters and sequels. If you want to browse millions of characters or build your own, PolyBuzz fits better, because Frontier has a small catalogue and no user-made characters.
Frontier is the closer fit if you want an actual game. You play through a visual novel to unlock a character, then keep talking to them and dating them after the ending. PolyBuzz is a chat app instead: reviewers describe opening it to a feed of characters, tapping one, and dropping into a chat that usually starts with a written greeting that sets the scene.
