Setting Up Your Knowledge Base

The knowledge base is the foundation of your AI agent. It determines what the bot knows and how accurately it can answer customer questions. HelpFaster uses a RAG (Retrieval-Augmented Generation) pipeline that retrieves the most relevant chunks of your content before generating a response.

Supported Formats

You can add content in several ways:

• PDF — Upload product manuals, whitepapers, or any PDF document. Text is extracted automatically.
• Markdown — Ideal for developer documentation and help articles.
• HTML — Paste raw HTML or provide a URL; HelpFaster strips the markup and indexes the text content.
• Plain text — Copy and paste FAQ answers, support scripts, or any text.
• URL crawl — Provide a root URL and HelpFaster will crawl the page (and optionally its sub-pages) to pull in content.

Adding Sources

Navigate to your chatbot's Knowledge Base tab and click Add Source. Choose the source type, upload or paste your content, and click Save. HelpFaster will begin indexing immediately.

Each source is split into chunks — small segments of text that the AI can retrieve independently. Chunking happens automatically; you do not need to worry about splitting your documents manually.

Re-Syncing Content

Content changes over time. When you update a document or your website changes, you can re-sync a source to refresh the index:

1. Open the source you want to update.
2. Click Re-sync (or upload a new version of the file).
3. HelpFaster re-indexes the content and the bot starts using the updated information within minutes.

For URL sources, re-syncing re-crawls the page and picks up any changes since the last crawl.

Best Practices

• Be specific. Upload content that directly answers the questions your customers ask. Avoid dumping entire websites unless the content is relevant.
• Keep sources organized. Name each source clearly so you can identify it later — for example, "Return Policy" or "API Quickstart Guide."
• Review knowledge gaps. Use the Analytics page to see which questions the bot could not answer and add content to fill those gaps.
• Use Markdown headings. If you write content from scratch, use clear headings (#, ##) to help the chunking algorithm create meaningful segments.

Limits

Each plan has a page limit that determines how much content you can index across all sources. One "page" is roughly 500 words of text. Check your plan's page limit on the billing page.
