Add an AI chatbot to any website with one script tag. Papaya Assist answers from your own documents via RAG, with a free tier and paid plans from $49.99/yr.
Papaya Assist is a document-grounded AI chatbot that website owners can embed with a single script tag. Instead of relying on general AI knowledge, it uses retrieval-augmented generation over documents the site owner uploads (PDF, DOCX, or plain text), so answers are scoped to the site's own content. Responses stream to visitors token-by-token via server-sent events, and the widget runs inside a Shadow DOM to avoid CSS conflicts with the host page, adapting between full-screen and compact panel layouts on mobile.
Beyond the raw JavaScript embed, Papaya Assist offers a WordPress plugin for non-technical users to install the chatbot without touching code. Setup is designed to take under a minute: create a free account, get a tenant ID, and upload documents. The underlying widget code is open source on GitHub, while the hosted backend (document processing, chat API, and usage limits) is a separate paid SaaS service.
Key Features
One-line script embed — Add the chatbot to any website with a single script tag, no build step or dependencies required.
Document-grounded answers (RAG) — Upload PDF, DOCX, or text files; the chatbot answers using retrieval-augmented generation over your own content instead of generic AI knowledge.
Streaming responses — Answers appear token-by-token in real time via Server-Sent Events.
WordPress plugin — Non-technical users can install and configure the chatbot through a WordPress plugin without editing HTML.
Shadow DOM isolation — The widget renders inside a Shadow DOM so its styles never conflict with the host site's CSS.
Mobile-responsive widget — The chat panel adapts between a full-screen view and a compact panel depending on screen size.
