What it does

Turn your knowledge into an AI assistant.

Give ChatAI your information, let it retrieve the right context, and deliver helpful answers through your website or application.

  1. 01

    Add knowledge

    Upload documents, content, or information your assistant should understand.

  2. 02

    Retrieve context

    ChatAI finds relevant knowledge before generating an answer.

  3. 03

    Embed anywhere

    Use the assistant through the hosted widget, React integration, or developer SDK.

Knowledge

Answers grounded in what you provide.

Instead of relying only on a model's general knowledge, ChatAI can retrieve relevant information from your own knowledge base before responding.

  • Document ingestion
  • Semantic retrieval
  • Configurable RAG settings
  • Context-aware responses
  • Source-aware workflows

Retrieval improves grounding, but answer quality still depends on your sources and model configuration.

Developers

Use ChatAI from your stack.

A hosted script for any site, a React component for app frameworks, the SDK when you want full control — or run the whole thing yourself.

Read the docs
chatai / react
$pnpm add @nightzeros/chatai-react
"use client";

import { ChatWidget } from "@nightzeros/chatai-react";

export function SupportChat() {
  return (
    <ChatWidget
      assistantId="your_public_assistant_id"
      apiUrl="https://app.nightzeros.com"
    />
  );
}

Customization

Make the assistant fit your product.

ChatAI can be configured for different websites and use cases — how the assistant behaves, how it looks, and how it retrieves knowledge.

Security

Designed for public embeds.

A public AI assistant needs more than a chat interface. ChatAI includes controls designed to help operators reduce abuse and control where assistants can run.

  • Domain allowlists

    Control which origins can run an assistant.

  • Widget rate limiting

    Throttle traffic from public embeds.

  • Bot heuristics

    Flag automated or abusive request patterns.

  • Optional widget signing

    Verify widget sessions when needed.

  • Encrypted provider credentials

    Provider keys are stored encrypted.

  • Audit events

    Track operational changes over time.

Security documentation

Privacy

Control what gets stored.

ChatAI gives operators control over conversation persistence and retention without requiring private message content for every operational workflow.

  • No-store mode

    Run conversations without persisting them.

  • Retention settings

    Decide how long data is kept.

  • Visitor anonymization

    Reduce identifying details on visitors.

  • Conversation export

    Take operational data with you.

  • Hard delete

    Remove stored conversations permanently.

  • Self-hosting

    Keep everything inside your own infrastructure.

Privacy documentation

Self-host

Your infrastructure. Your choice.

Use the hosted product for convenience or deploy ChatAI yourself when you want greater infrastructure control.
