Superinterface
Open-source React components and voice UI for embedding AI assistants into your product.
About
Superinterface is an open-source toolkit for adding in-app AI assistants to a website or product: drop-in React components, script tags, or hosted pages that render chat with markdown, forms, buttons, file search, and voice interactions. Assistants can call your functions and APIs, and billing is bring-your-own-key, so you pay OpenAI, Anthropic, Groq, or Mistral directly with no middleman markup.
The appeal is speed and control: a branded assistant UI in hours, fully customizable and self-hostable, instead of building chat primitives from scratch. The caveat is scale — it is a small open-source project (a few hundred GitHub stars), so expect community-paced maintenance rather than enterprise support. Worth evaluating if you want an embeddable assistant layer without a vendor platform.
What it can do
- Embeddable chat components, script tag, or hosted pages
- Voice interaction with text-to-speech support
- Function calling into your APIs and knowledge sources
- Bring-your-own-key billing with no usage markup
- Theming, avatars, and brand customization
Setup
Install the React components via npm or drop in the script tag, configure your provider API keys, and wire assistant functions to your backend endpoints.
Prerequisites
A React or web frontend; API keys from an LLM provider.
