How to Use KoboldAI in 2026: Step-by-Step Guide
KoboldAI is an open-source browser-based frontend for AI-assisted creative writing and roleplay. Run it with local models on your own hardware or connect to cloud APIs — with a rich story editor, memory/author's note/world info systems, and active community model sharing.
KoboldAI pioneered the open-source AI roleplay frontend space before SillyTavern's rise. It takes a story-editor approach rather than a chat interface — more like collaborative fiction writing than conversation, with persistent memory, author's notes, and a world info system built in.
Story Editor Interface
KoboldAI's primary interface is a scrolling story document, not a chat log. The AI continues the story from wherever you leave off. You write a passage, the AI extends it, you edit or steer, the AI continues. This feels more like collaborative writing than chatting, and is better suited for long-form narrative than chat-style roleplay.
Key controls:
- Retry: regenerate the last AI output
- Back: step back to before the AI's last addition
- Story memory: a persistent context block the AI always has access to, for tracking character names, world rules, ongoing plot
- Author's note: injected near the end of the context to influence tone and direction
- World info: dictionary-style entries that inject when keywords appear
Model Support
KoboldAI connects to:
- Local models via its own launcher (KoboldCpp, the most common)
- Google Colab (free GPU cloud for those without local hardware)
- OpenAI API
- NovelAI API
- Horde (distributed crowdsourced inference)
KoboldCpp, the companion tool, runs LLMs locally with GGUF/GGML model formats — compatible with all major open-source models (LLaMA, Mistral, Qwen, etc.).
Community
KoboldAI has an active Discord and subreddit. Community members share model configs, adventure modules, and presets. The format for adventure modules (.json scenario files) is well-established.
Who It's For
KoboldAI is ideal for writers who want AI as a story co-author rather than a conversational character. Its editor interface supports long-form fiction better than most chat-centric alternatives.
What You'll Need
- A KoboldAI account (free to create)
- A modern web browser or the KoboldAI app
Getting Started
Create Your Account
Visit https://github.com/KoboldAI/KoboldAI-Client and sign up for a free account. You'll need an email address to register.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. KoboldAI supports ai-story-writing, local-model-support, story-memory-system, world-info, collaborative-fiction, open-source, colab-support, long-form-narrative — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show KoboldAI what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.

- The tool isn't responding or is slow
- AI chatbots can experience high traffic. Refresh the page and try again. Check the service's status page if issues persist.
