1.2 Core Concepts of Pop
To help you fully understand Pop’s overall capabilities, this chapter introduces several core concepts.
Once you understand them, you will be able to more efficiently use Pop to manage knowledge, process documents, build automation workflows, work with AI, publish applications, and manage your website visitors and customer service.
🌐 1. Document Center
The Document Center is the foundational module of Pop, responsible for managing all your local documents.
All documents are stored locally and are never uploaded to the cloud automatically.
Supported formats include:
- Word / Excel / PowerPoint
- Markdown
- TXT
- Images (JPG / PNG / WebP, etc.)
Key capabilities:
- Reading & previewing
- Highlighting & note-taking
- Automatic table of contents parsing
- In-document search
- AI-powered document Q&A
- Batch import
💡 The Document Center can be seen as the entry point to all knowledge, and one of the input sources for the Knowledge Base and Workflows.
🧠 2. Pop Copilot (AI Engine)
Pop Copilot is Pop’s AI engine and powers intelligence across all modules.
It is not just a chat assistant, but a system that can:
- Read and understand documents
- Execute nodes inside workflows
- Process structured and unstructured data
- Interact with the Knowledge Base
- Generate charts, text, code, and reports
- Act as the AI co-pilot of your entire system
Pop supports multiple AI models simultaneously, such as:
- OpenAI
- DeepSeek
- Moonshot
- OneAPI / self-hosted model services
- Third-party OpenAI-compatible APIs
You can assign different models to different modules—for example:
Model A for the Knowledge Base, and Model B for Workflows.
📚 3. Knowledge Base
The Knowledge Base enables AI to perform precise Q&A based on your materials.
Unlike ordinary document reading, the Knowledge Base performs structured processing:
- Automatic chunking
- Text cleaning
- Index building
- BM25 / Vector / Hybrid search
- Retrieval (best text segments)
- Reranking
Suitable for:
- FAQ development
- Product documentation
- Internal team manuals
- Technical archives
- Study notes systems
- Website customer service backends
📌 Compared with Document Center:
Document Center is for human reading,
Knowledge Base is for AI retrieval and automated answering.
🔧 4. Workflow
Workflows are one of Pop’s strongest modules, enabling you to build complex automation tasks without writing code.
A workflow includes:
- Nodes — individual execution steps
- Connections — data flow between nodes
- Variable system — store and pass intermediate results
- Run logs — debugging and monitoring
- Publish as App — turn workflows into reusable interactive applications
Common node examples:
- AI conversation / content generation
- Text processing (formatting, extraction, replacement)
- PDF generation & merging
- Excel import / export
- Image transcoding & compression
- HTTP requests to external APIs
- JSON parsing & field extraction
- Chart generation
- File reading & writing
Suitable for building:
- AI-generated reports, documents, weekly summaries
- Data batch processing and format conversion
- Static site auto-generation
- AI content moderation
- File conversion & batch analysis
- Internal workflow automation (approval, syncing, etc.)
📦 5. Apps
Pop allows you to package workflows into interactive apps.
Each App can:
- Design its own UI layout (forms, result sections, chart areas, etc.)
- Define multiple input fields
- Output text, charts, and files
- Run as an independent application instead of a workflow editor
- Have its own run logs and debugging tools
An App is essentially:
“The final product form of your AI tools, workflows, and automated scripts.”
Suitable for building:
- Content or article generators
- AI résumé analyzers
- Financial report generators
- Website asset processing tools
- Sales proposal generators
- Data visualization tools
📊 6. Site Analytics & Chatbot
Pop’s JS SDK can be embedded into any website to provide:
① Website Visitor Analytics
- Real-time visitor tracking
- Visitor location analytics
- Device & browser information
- Page dwell time & bounce rate
- Page navigation paths
② AI Website Chatbot
- FAQ Q&A based on your Knowledge Base
- Multi-language support
- Custom themes & greeting messages
- Works jointly with Pop Copilot
- Embeddable page-side chat widget
Ideal for website owners, small teams, and independent developers.
