What Makes a Knowledge Base Good?
A great knowledge base is more than a document dump. It needs comprehensive coverage of your customers' questions, accurate and up-to-date information, proper structure for AI retrieval, and confidence scoring so your chatbot knows when to escalate to a human.
Document Types That Work Best
Chatloom supports a wide range of content sources. The key is choosing the right format for each type of knowledge. Here are the formats that deliver the best results for AI-powered customer support.
PDF Documents
Extract text from manuals, policies, and reports
Best for: Help docs & manualsWord Documents
Import DOCX files with formatting preserved
Best for: SOPs & internal docsWeb Pages
Crawl and index live web content automatically
Best for: FAQ pages & blogsPlain Text
Simple text files and markdown content
Best for: Quick knowledge snippetsShopify Products
Sync product catalog with descriptions and metadata
Best for: E-commerce storesCSV / Spreadsheets
Structured data from spreadsheets and databases
Best for: Product specs & pricingThe Chunking Problem
Raw documents are too large for AI models to process effectively. Chunking splits your content into optimally-sized segments that preserve meaning and context. But naive chunking creates fragments that lose their original context. Chatloom solves this with contextual chunking — each chunk carries metadata about the document it came from.

Contextual Retrieval
The secret to accurate AI answers is a robust retrieval pipeline. Documents flow through multiple stages — from upload to chunking, embedding, and vector storage — before they are ready to serve real-time answers. Each stage is optimized for accuracy and speed.

Documents ingested from multiple sources
Chunking
Split into optimal-size segments
Embedding
Converted to vector representations
Vector DB
Stored for fast similarity search

Get Started FreeFrequently Asked Questions
How often should I update my knowledge base?
At minimum monthly, but ideally whenever your product, pricing, or policies change. Chatloom supports auto re-crawling on daily, weekly, or monthly schedules to keep your knowledge base fresh.
What file formats does Chatloom support?
Chatloom supports PDF, DOCX, plain text, web page URLs, Shopify product sync, and CSV files. Each format is optimized for the best chunking and embedding results.
Can the chatbot learn from my website automatically?
Yes. You can provide your website URL and Chatloom will crawl and extract content automatically. You can also set up scheduled re-crawling to keep the knowledge base updated.
How does Chatloom handle conflicting information?
Chatloom uses confidence scoring and source citations. When conflicting information exists, the system flags lower-confidence answers and can escalate to human support.
What happens when the chatbot can't find an answer?
Chatloom uses a 4-level confidence system (high, medium, low, none). When confidence is low or none, the chatbot transparently admits it doesn't know and can hand off to a human agent.
