Key Concepts
Before diving in, it helps to understand the core concepts that make WizChat work.
Chatbots
A chatbot is your AI assistant. Each chatbot has:
- A unique name and identity
- Its own knowledge base (documents)
- Configuration settings (AI model, prompts, appearance)
- A deployment URL for users to access
You can create multiple chatbots for different purposes (support, sales, internal docs, etc.).
Knowledge Base
The knowledge base is the collection of information your chatbot uses to answer questions. It includes:
- Documents - PDFs, Word files, spreadsheets, images
- Web content - Pages crawled from websites
- Videos - YouTube videos and uploaded video files (transcribed)
When you upload content, WizChat processes it and creates embeddings - mathematical representations that allow the AI to find relevant information quickly.
Embeddings
Embeddings are how WizChat understands and searches your content. When a user asks a question:
- The question is converted to an embedding
- Similar content is found in your knowledge base
- Relevant context is sent to the AI model
- The AI generates an answer based on that context
This process is called Retrieval-Augmented Generation (RAG).
Teams
A team lets you collaborate with others. Team features include:
- Members - People who can access shared chatbots
- Roles - Owner, Admin, Member with different permissions
- Shared chatbots - Chatbots accessible to all team members
Chatbot Users
Chatbot users are the people who interact with your deployed chatbot. You can:
- Allow open access - Anyone with the link can chat
- Require authentication - Users must log in
- Manage users - Invite specific people, track sessions
MCP Servers
MCP (Model Context Protocol) servers extend your chatbot's capabilities by connecting to external tools:
- Query databases (PostgreSQL)
- Access business tools (Salesforce, Atlassian)
- Perform calculations
- And more
Plans and Usage
WizChat offers different subscription plans with varying limits on:
- Number of chatbots
- AI budget (cost-based, not query-based)
- Storage space
- Team seats
- Features (custom domains, remove branding, etc.)
How AI Budget Works
WizChat uses cost-based billing. Your AI budget is consumed based on actual AI usage costs, not a fixed number of queries. This is fairer because complex queries cost more than simple ones.
| Plan | AI Budget |
|---|---|
| Free | $5 one-time (never resets) |
| Starter | $20/month |
| Pro | $50/month |
| Pro+ | $100/month |
| Business | $200/month |
The free plan budget is a one-time grant that does not renew. Paid plan budgets reset monthly.
