Talkie vs Character.AI vs PolyBuzz: The Free AI Companion Apps Compared
Ask which AI companion you can actually run without paying and three names dominate the answer: Talkie, Character.AI, and PolyBuzz, the app many people still search for under its old name, Poly.AI. All three let you start chatting within a minute of install. The similarity ends there. One is a gacha game wearing a companion costume, one is the biggest free stage in the category, and one sells memory back to you in tiers. Which free tier survives contact with a real week of use depends on what you want a companion for, so that is how this comparison is organized.
Two of these apps, Talkie and Character.AI, already went through our seeded-facts testing for the main roundup, so their memory numbers below come from that work. For PolyBuzz we spent time on the free tier and leaned on the company's own published plan descriptions for the limits we could not measure directly. Everything here reflects mid 2026. Companion apps ship changes weekly, models get swapped under your feet, and prices drift, so treat specifics as a snapshot and check in-app before you pay anyone.
First, the Poly.AI name problem
Two unrelated products share this name, and search results mix them freely. Poly.ai, the enterprise company, builds voice assistants for call centers and hotel chains; it has nothing to do with companions. The consumer roleplay app that grew up under the Poly.AI name now operates as PolyBuzz, and the old reviews, app store listings and forum threads about companion chat almost always mean this one. If the page you are reading talks about anime companions rather than customer service automation, it means PolyBuzz. That is the app we compare here, under its current name.

Talkie: the gacha companion
Talkie has the slickest onboarding of the three and is the most honest about what it is, if you know how to read the interface. In-app currency, card draws, collectible character cards: this is free-to-play game design applied to conversation partners. Voice is the real draw. Characters speak out loud, a mini-theater mode animates chats into small visual scenes, and the anime and fan-fiction catalog runs deep. As a five-minute toy it is genuinely fun, and comparison listings put its entry subscription around seven dollars a month, the cheapest paid tier in this trio.
The problem is everything underneath. In our roundup testing Talkie recalled about 6 of 20 seeded personal facts, the weakest memory score we have measured in any companion app, and personalities wobble between sessions. App store builds filter adult content. The free tier leans on ads, and reviewers keep raising questions about its data practices and corporate ownership. None of that matters for casual play. All of it matters if you are tempted to make Talkie a daily emotional habit, which is precisely what its reward loops are built to encourage.
Character.AI: the biggest free tier
Character.AI remains the obvious first stop, because its free tier is the most generous in the category: the full catalog of user-created characters, unlimited core chat, and a paid tier that mostly buys speed and priority rather than access. For variety, roleplay, debate partners and fiction, nothing free comes close, and the subscription has hovered around ten dollars a month for a long while.
The trade-offs are the same ones we logged in our month-long comparison. Long-arc memory is weak: about 9 of 20 seeded facts in our test, even with pinned memories in play, and consistency varies character to character. Filters are the strictest of the three and apply to everyone, and after sustained safety scrutiny the company has restricted open-ended chat for minors. Whether the filter is a dealbreaker or a feature depends entirely on you. It is the reason Character.AI is the easiest of the three to recommend to a curious adult, and the least likely to satisfy anyone who came specifically for unfiltered companionship.
PolyBuzz: memory as a product
PolyBuzz competes on volume and permissiveness. The company claims a character catalog in the tens of millions, the community skews hard toward roleplay, and its filters are the loosest of the three for adults, which explains how it absorbed so many users bouncing off Character.AI's restrictions.
Its monetization is the most interesting and most cynical part of this whole comparison. As of mid 2026, PolyBuzz's published tiers run from $9.90 to $29.90 a month, and what they primarily sell is memory: per its own plan descriptions, the free experience keeps a rolling context of roughly 30 messages, a middle tier extends that window several times over, and permanent memory is reserved for the top tier. Read that again. The app remembers you in proportion to what you pay. In a category where being remembered is the emotional product, that is the entire relationship priced as a subscription ladder. Free users get breadth, ads and amnesia; continuity costs more here than anywhere else in this piece.
Where free actually ends
The three apps meter different resources, which is why a free week feels so different in each. Talkie meters engagement: energy systems, draws and ads nudge you constantly, even while chat itself flows. Character.AI meters speed: you can talk all day and simply wait longer at peak hours. PolyBuzz meters memory: conversation is cheap, continuity is not. So the practical question is not which app is free, since all three technically are, but which meter you can live with. Casual visitors barely notice any of them. Daily users hit Talkie's and PolyBuzz's walls within days, while Character.AI's free tier genuinely holds up for weeks, which matches what we found in our longer tests.
Who should pick what
- Pick Talkie for voice-first casual play, and accept that it is a game. Do not build anything on it you would mind losing.
- Pick Character.AI for variety and the best free tier in the category. Accept strict filters and weak long-term memory.
- Pick PolyBuzz if permissive, high-volume roleplay is the point and you are a paying adult. The free tier is a demo of a relationship it will not let you keep.
- Pick none of them as a primary emotional support. Our standing rule applies to all three: a companion app should supplement your week, never substitute for the humans in it.
Frequently asked questions
Is PolyBuzz the same thing as Poly.AI?
The companion app once marketed as Poly.AI now operates as PolyBuzz. It is unrelated to Poly.ai, the enterprise voice assistant company. Old reviews and app links about companion chat almost always mean the app now called PolyBuzz.
Which free tier lasts longest before a paywall?
Character.AI. Its free plan covers unlimited core chat, with speed and priority as the main paid perks. Talkie and PolyBuzz meter the free experience sooner through energy systems, ads and message context limits.
Which app remembers you best without paying?
None of the three is strong on a free plan. Talkie posted the weakest memory score we have measured, and PolyBuzz reserves deeper memory for its higher tiers, so Character.AI with pinned details is the least bad free option.
Are these apps suitable for teenagers?
No. We review companion apps for adults. Character.AI has restricted open-ended chat for minors after safety scrutiny, and the other two combine attachment mechanics with monetization in ways that are a poor fit for teens.
If what you actually want is one continuous companion rather than a free playground, the deeper read is our month-long Replika, Character.AI and Nomi test below. And because free tiers, filters and price ladders in this category change monthly, we track them so you do not have to: new reviews, privacy changes worth knowing and pricing-trap alerts all land in the free monthly digest, one email a month, no noise.
