Knowledge Base

The co-pilot doesn't guess — it answers from your content. The knowledge base is the indexed collection of documentation, files, and web pages that Pillar searches when a user asks a question.

How It Works

When a user asks a question, Pillar retrieves the most relevant sections from your indexed content and passes them to the co-pilot as context. The co-pilot then builds a response grounded in that content. If nothing relevant is found, it tells the user rather than making something up.

This is called retrieval-augmented generation (RAG) — a standard pattern for grounding LLM responses in source material.

Content Sources

Pillar supports four ways to get content into your knowledge base:

Source	Description
Website	Automatically crawl and index a docs site, help center, or marketing page
Files	Upload PDFs, Word documents, and text files directly
Cloud Storage	Sync documents from an Amazon S3 or Google Cloud Storage bucket
Snippets	Write custom text for corrections, FAQ answers, or topic-specific AI instructions

All sources are searched together at query time. The co-pilot finds the best matches regardless of source type.

What Users See

Users don't interact with the knowledge base directly. They just ask questions in the co-pilot and get answers. Behind the scenes, the co-pilot is searching your knowledge base and using the results to respond.

Progress indicators show when the co-pilot is searching, so users know their question is being processed.

Feedback Loop

When users rate responses with thumbs up or down, that feedback is captured in your dashboard. Use it to identify gaps in your knowledge base — if users keep asking about a topic and getting poor answers, you probably need to add content for it.
