Tavern-Helper (JS-Slash-Runner) is a SillyTavern extension that lets users run external JavaScript inside the chat via sandboxed iframes. It provides APIs for rendering rich HTML/CSS/JS interfaces in messages, managing variables and world books, controlling AI generation, handling events, and playing audio.

Use cases

• render interactive HTML interfaces inside SillyTavern chat messages
• run custom JavaScript scripts in SillyTavern
• manage world book entries programmatically
• store and retrieve variables usable in prompts
• customize AI generation settings and inject prompts
• listen to and trigger SillyTavern events
• play background music and sound effects in chats

When to choose

• you use SillyTavern and want rich, interactive frontends embedded in conversations
• you need to script SillyTavern behavior with JavaScript
• you want to build roleplay cards with dynamic UI, audio, or state

When to avoid

• you don't use SillyTavern
• you can't trust the scripts you'd run, since arbitrary JS execution carries security risks
• you need a general-purpose browser automation tool outside SillyTavern
