Roleplaying with AI is fun and addictive. You can let your creativity run wild and interact with countless characters, scenarios, and topics. But online AI roleplay platforms have annoying filters, features locked behind subscriptions, and can access your “private” conversations.
That’s where SillyTavern steps in. A free and private alternative that you have complete control over because it runs on your device.
What Is SillyTavern
SillyTavern is a free, open-source frontend for interacting with LLMs that you can run locally on your device. It removes the need for online sites and services for AI roleplay. While it isn’t as simple to set up compared to plug-and-play online platforms, it offers you more control over your experience.
The project started as a fork of TavernAI in 2023 and now has over 200 contributors who develop and maintain SillyTavern as the leading local frontend for AI roleplay.
SillyTavern remains committed to being free and open-source, supported by a dedicated community of LLM enthusiasts ready to help others. This makes the feature-rich frontend an excellent choice for local AI roleplay.
SillyTavern: The Feature-Rich Frontend
The contributors’ passion and love for the hobby, along with their dedication to enhancing user experience, have made SillyTavern a feature-rich frontend for AI roleplay.
Character Creation
You create characters by giving them unique personalities, backstories, appearances, quirks, and even a distinctive speech style. You can flesh them out further for a more immersive roleplay experience by utilizing features like scenario settings and lorebooks to craft a detailed world around your character.
SillyTavern also makes it easy to share your creations or import character cards. If creating characters isn’t your thing, you can import existing character cards and jump right into roleplay.
Lorebooks
Lorebooks (also known as World Info in SillyTavern) in AI roleplay help you keep an efficient context cache by moving unnecessary details from permanent tokens into a structured, retrievable information library.

Your AI characters will only draw relevant information when needed, making your roleplay more immersive without the hassle of managing context limits or using excessively large context windows. You can also share lorebooks across multiple characters to build a larger, interconnected narrative universe.
Advanced Text Generation
When you interact with an LLM, everything acts as a prompt. Instructions, character definitions, persona details, scenarios, lorebooks, and your messages to the AI are all prompts. SillyTavern provides you with intuitive tools to create and structure prompts.
You have greater control over how the LLM processes information, allowing you to influence output style and model behaviour to generate the exact kind of responses you want. You don’t need to struggle with limited custom prompts or basic generation settings provided by online AI roleplay platforms.
The SillyTavern community has also created several presets that you can import and use, allowing you to jump straight into roleplay without the hassle of creating and managing prompts.
Chat Management & Group Chats
You can create checkpoints, branch chats from specific messages, exclude messages from prompts, use commands, and do more to have complete control over your chat experience. SillyTavern also lets you export chats to share with others, or import chats shared by others to continue their story.
And what’s better than roleplaying with an AI character? Roleplaying with two or more AI characters! SillyTavern supports group chats so you can have fun with as many characters as you want.
User Persona Management
Define your persona and give the AI details about your character for maximum immersion. With SillyTavern, you can create and manage as many personas as you want, unlike online platforms that limit you to a few.
You can lock personas to chats and characters, ensuring you use the correct persona during roleplay. SillyTavern also lets you easily convert a character into a persona, so you can not only roleplay with them but also roleplay as them.
Backend Flexibility
SillyTavern supports a wide range of LLM backends, enabling you to run LLM models locally for AI roleplay using KoboldCpp or Oobabooga, or access larger, more advanced models through official APIs and proxy services like DeepSeek and OpenRouter.

Hosting LLM models locally ensures complete privacy and lets you enjoy the hobby without having to put up with daily limits or expensive subscriptions. But if you don’t have the hardware to run models locally, you can use official APIs and proxy services, though most charge fees and have access to your prompts and outputs.
You can also run a KoboldCpp instance on an online service like Runpod*, allowing you to run powerful models on rented GPUs and keep prompts and generations private while using SillyTavern as your frontend.
* The Runpod link is a referral link that benefits KoboldCpp directly. By signing up with their referral link, you get a one-time credit from Runpod when you add $10 to your account.
UI Customization and Extensions
You can customize the frontend with themes and CSS modifications. SillyTavern also has several built-in and community-created extensions that add new features, change how existing features work, or provide additional content for your AI to use.
While SillyTavern’s official extensions add functionality, community-created extensions bring fun content and features to enhance your AI roleplay experience.
RAG, TTS, and More
- Built-in support for Retrieval-Augmented Generation (RAG), a method that allows LLMs to retrieve information from a database, often including details outside their training data, improving context-awareness and response accuracy.
- Extensions for Text-to-Speech, Image Generation, and Character Sprites (expressions) to make your roleplay experience more immersive.
- Supports multiple languages with automatic UI and chat translations.
- Built-in support to access your local SillyTavern installation over LAN or the internet from any device.
- Comprehensive documentation to help you learn how to use SillyTavern, along with an active community on Reddit and Discord.
Why Use SillyTavern
SillyTavern is a free, feature-rich frontend for AI roleplay, unlike many online platforms that push users toward subscriptions and microtransactions just to access basic features. Privacy is also never guaranteed with these platforms. Your chats and characters, even if kept private, can be accessed by operators or third-party services they employ.
Using SillyTavern with a backend like KoboldCpp to run an LLM model locally gives you complete control over your data. No one is spying on your chats, reviewing your prompts, or checking your outputs. Your privacy is guaranteed.

Additionally, you can import or export almost any type of data and settings on SillyTavern. It’s built around the idea of empowering individuals to create and share for the benefit of the community that enjoys this hobby, unlike online platforms that profit from user-generated content.
Online platforms might also make sweeping policy changes or even disappear without warning. But SillyTavern is here to stay. Its dedicated contributors continue to develop features to improve user experience and update the software to ensure compatibility with various operating systems.
SillyTavern’s Only Drawback: A Learning Curve
Unlike online platforms that work out of the box with minimal effort from the user, SillyTavern has a learning curve and needs some time to set up properly.
But the learning curve is fun, especially if you enjoy AI roleplay and want to learn more about how LLMs work. The process is worthwhile because of the level of control and freedom you have to shape your experience.
SillyTavern’s comprehensive documentation, its helpful community, and various guides and videos assist you in getting started. Once you understand the basics, it’s very easy to customize and use it in any way you want.
