The short answer

A sales chatbot needs three parts: a chat widget (Chatbot UI, 33,329 stars, MIT), a knowledge base so it answers from your real product info (AnythingLLM, 64,364 stars), and a handoff rule to a human when the lead is hot. All three are free and self-hosted.

The architecture

1. AnythingLLM ingests your product pages, FAQ and pricing into a RAG workspace.
2. Chatbot UI (or AnythingLLM's own embeddable chat) sits on your site.
3. The LLM answers product questions with citations to your docs - no hallucinated prices.
4. A simple rule: when the user asks about pricing, plans or "talk to sales", capture the email and notify your team (n8n, 199,396 stars, can automate this).

Deploy in 30 minutes

# AnythingLLM
git clone https://github.com/Mintplex-Labs/anything-llm.git
cd anything-llm; docker compose up -d

1. Open the AnythingLLM UI, create a workspace, upload your product docs.
2. Use the built-in chat embed: copy the script tag into your website footer.
3. Point the LLM provider at Ollama (177,825 stars) for $0 running cost.

What to feed the bot

• Product pages and spec sheets (the bot must never invent specs)
• Pricing page content (keep it current)
• FAQ + shipping/returns policy
• Your top 20 support tickets as "how to answer" examples

Real numbers

• A well-fed RAG bot answers ~70-80% of pre-sales questions correctly, matching typical FAQ coverage.
• AnythingLLM embeds stay free with no message caps when self-hosted.
• Typical result: fewer basic queries reaching human agents, faster first response time.

FAQ

Q: Will it hallucinate prices? A: Only if the pricing doc is missing. Keep the pricing page in the workspace and instruct the bot to cite sources.

Q: How do I capture leads? A: Add a form step before the handoff, or use n8n to watch for keywords and push the conversation to your CRM.

Q: Mobile-friendly? A: Yes - the embed is responsive and works as a floating widget on mobile sites.
