Can the AI train on PDFs?

Yes. Good products accept PDF, DOCX, TXT, Markdown. Upload them from the admin panel.

Does structure matter?

Less than you think. LLMs handle unstructured text well. Clarity and completeness matter more.

How to Build a Knowledge Base for Your AI Chatbot

By Arden Talbot·May 9, 2026

The single biggest determinant of AI chatbot quality is the knowledge base. Model choice matters 10%. Content quality matters 90%. This piece is the practical guide to building one.

What to include

Top 50 customer questions. Pricing and plan details. Shipping, refunds, guarantees. Hours, locations, contact info. Product specs. Policy docs.

How to format

Short paragraphs. One idea per paragraph. Plain-English headers matching how customers phrase questions. Bulleted lists where possible.

Maintenance schedule

Weekly: review the top 10 questions the AI could not answer. Monthly: audit stale pages (pricing updates, new product lines). Quarterly: rebuild the top-level FAQ structure based on what customers actually ask.
