About Simsimi
What Is SimSimi
SimSimi is an AI chatbot app and website operated by the Korean company ISMaker. It went live in 2002, long before modern large language models, and its replies come from question and answer pairs that users have taught over the years. The official bot is called Everyone's SimSimi, and it learns from the crowd rather than from a model update pushed out by the company.
The service has two sides. Everyone's SimSimi is the round yellow character that answers with jokes, comfort, or random facts. A personal SimSimi is a character you own: you choose the avatar, write the personality, and decide whether it replies to other people on its own. A public library of AI characters sits on top of that, mixing fantasy nobles, singers, and deliberately rude parodies, each with its own chat count.
The limits deserve equal billing. SimSimi is built for casual conversation, not research, coding, or document work. Answers can be wrong, repetitive, or crude because much of the training data came from users, and ISMaker leans on a content policy and age limits instead of promising a clean chat every time.

Key features
Everyone's SimSimi, the Shared Chatbot
Everyone's SimSimi is the original character and the reason the app exists. Its answers come from pairs of questions and replies submitted by users, so the personality shifts with whatever the crowd taught it that week. That makes it unpredictable in a way modern assistants are not, and it also explains the odd, funny, or blunt responses people screenshot.
Personal SimSimi and Character Creation
The Create flow turns a user into a bot owner. You pick an avatar, write a name and description, and shape how the character speaks. Owners can chat through their own character and can set it to answer other people automatically, which turns a private joke into a public persona.
Teach SimSimi New Replies
Teaching is the oldest feature and still the core loop. When a reply is wrong or dull, you submit a better answer for the same question, and the pair enters the pool that Everyone's SimSimi draws from. It's a slow, collective way to build a chatbot, and it gives users a stake that polished assistants never offer.
A Library of AI Characters to Chat With
Beyond the yellow chick, the platform lists hundreds of community characters with distinct voices and settings. Some are romance leads, some are historical figures, some exist to be insulted. Each card shows a chat count, so popular personas are easy to spot before you open a conversation.
Chat in 81 Languages
SimSimi supports 81 languages, and the interface follows the one you pick. The quality varies by language because the reply pool depends on how many people taught that language, which is worth knowing before you judge the bot on a single bad answer.
Safety Tools and Content Policy
ISMaker publishes a content policy and gives users a report button for chats, characters, and accounts. The team also applies age restrictions, since a crowd-taught bot can produce sexual language, bullying, or threats. Reporting is the main lever a user has, and the company says it acts on the accounts behind flagged content.
Points, Boost, and Membership
Chatting is free, but extra reach costs money. Points unlock premium interactions, Boost credits push a personal character up the discovery list, and a membership removes some limits. Coin packs range from under a dollar to a few hundred dollars, so spending can scale far beyond a normal subscription.
Pros and cons
Pros
- Free to start, with no credit card and no prompt setup before the first message.
- 81 languages and a web version, so the same account works on a phone or a laptop.
- Character creation is genuinely simple, which suits people who freeze at a blank prompt box.
- The crowd-taught reply pool produces humor and surprise that polished AI chatbots rarely match.
Cons
- Answer quality is inconsistent, since replies depend on what strangers taught the bot.
- Content moderation is reactive, so rude or sexual replies can still surface before a report lands.
- Coin packs and Boost credits create spending pressure that a plain monthly subscription avoids.
- There's no API, so developers can't wire SimSimi into their own apps or workflows.
