PolyBuzz Alternatives (2026): 10 AI Character Apps

PolyBuzz is one of many apps for chatting with AI characters, and the people searching for something else rarely want the same thing. One person wants a character who remembers them, another wants thousands of characters to browse, and someone else wants to write a story with an AI co-author.

PolyBuzz itself isn't in this list. The ten apps below are listed alphabetically and in no particular order, and every description comes from the developer's own website, read as of Nov 2026. I've kept to what each page says about characters, stories, companions and privacy.

Ten AI character apps to try instead of PolyBuzz

Chai

Best for: Making your own AI characters and stories in a phone app, from a company that says it builds its own in-house chat models.

Character Tavern

Best for: Browsing a big catalogue and building your own characters in its Studio, from a site that names a generous free tier on its home page.

Character.AI

Best for: Exploring a huge library of characters, from an app that says it helps people connect, learn and tell stories through interactive entertainment.

ChatFAI

Best for: Finding characters by topic, with categories running from Anime and Book to Education, History, and TV Shows and Movies.

Cleverbot

Best for: Curious chatters who'd like a classic bot whose site dates back to 2006 and which says what you tell it may shape what it tells others.

Dopple

Best for: Picking characters from themed shelves such as Philosophers, Helpers, Games and Comics, from an app that bills itself as your AI adventure.

HammerAI

Best for: Privacy-minded chatters, since its desktop app can run the language model on your own computer, and it also writes stories and makes images.

Kindroid

Best for: Anyone after one AI friend who, in the app's own words, listens, remembers and grows with you, by text, voice or video call.

NovelAI

Best for: Writers building stories, worlds and characters with an AI that, in its own words, writes with you rather than for you.

Replika

Best for: People who want a single AI friend on iOS or Android, from a company that says it built the first AI companion ten years ago.

Companion, character library, storybook or private chat?

Read the developer pages side by side and four kinds of app appear. Replika says 'We built the world's first AI companion', and Kindroid pitches 'Your AI friend who listens, remembers, and grows with you everyday', with 'Study buddy' among the ways to use it. These are companions: one character, one ongoing relationship.

Then there are the libraries. Character.AI offers 'millions of Characters to discover', Character Tavern says 'Chat with over 18.5K+ AI Characters' (the site's own count), Dopple.ai sorts characters under headings such as 'Philosophers', and ChatFAI files them under headings that include 'Education'. Chai's own page describes 'a consumer platform where users can build their own AI characters and stories'.

NovelAI is an 'AI Anime Image Generator & Storyteller', so it leans towards writing more than chatting. HammerAI calls itself an 'AI character chat and roleplay platform' and says you can 'run the LLM on your local machine for total privacy'. And Cleverbot, which invites you to 'speak to AI with some Actual Intelligence', is the old-school option.

That's the split a PolyBuzz user wouldn't guess: these apps aren't all doing the same job. Some are companion apps, some are character libraries, one is built for stories, and one offers local, private chat on your own machine.

What to look at before you switch from PolyBuzz

• Memory. If you want a character who remembers what you told it last week, look for apps that talk about memory and long conversations, not only big character counts.
• Who makes the characters. Libraries filled by users give you variety, though quality varies. Apps built around one companion give you depth instead of range.
• Where your chats are stored. Most apps run on the developer's servers. If privacy matters most, look for a desktop app that can run a model on your own machine, and read the privacy policy either way.
• Phone, browser or desktop. Some of these are phone-first, some live in the browser and a few have a desktop download. Pick the one that fits where you chat.
• Voice and images. A few apps add voice calls, image generation or video. They're fun extras, so check which ones come with the plan you choose.

Moving your characters from one app to another

There's no standard export between character chat apps, so expect to rebuild a character you like rather than move it. Keep a short note of each character's name, personality, backstory and the way it talks, and you can recreate it in any app that lets you make your own characters.

If you'd rather build a chatbot for a business than chat with one, my guide to chatbot builders for small business covers that side.

Five questions to ask any PolyBuzz alternative

1. Does it remember earlier conversations, and for how long?
2. Can I create my own characters, or only chat with ones other people made?
3. Where are my chats stored, and can I delete them?
4. Does it work on the device I use most?
5. Which features are free, and which need a subscription?

My advice if you're moving on from PolyBuzz

Work out which of the four jobs you want done first. If you want one character who gets to know you, try a companion app. If you like browsing and swapping between characters, a big library fits better. If you're writing a story, pick the storytelling tool, and if privacy is the worry, a desktop app with a local model keeps chats on your own machine. Try two at most, give each a week, and keep the one you go back to without thinking.

Frequently asked questions

What is the best PolyBuzz alternative?

There's no single answer, because these apps do different jobs. Companion apps suit an ongoing friendship, character libraries suit browsing, storytelling tools suit writers, and a desktop app with a local model suits privacy. Start with the job you want done.

Are there free PolyBuzz alternatives?

Some apps on this list name a free tier or say chatting is free on their own pages, as of Nov 2026. Free tiers change often, so check the developer's site before you sign up.

Can I use an AI character app privately?

Most character apps run on the developer's servers. A few desktop apps can run the language model on your own computer, which keeps chats on your machine. Read each app's privacy policy either way.

Can I create my own characters?

Most of the apps here let you create characters as well as chat with other people's. Companion apps usually focus on shaping one character around you rather than a public library.

What's the difference between an AI companion and a character app?

A companion app centres on one character that remembers you and builds a relationship over time. A character app gives you a library of many characters, usually made by other users, to chat with.

Do these apps work on phones?

Many of them have iOS or Android apps, some run in a browser, and a few offer a desktop download. Check the developer's site for the device you use.
