How to set up AI auto-reply for customer support

Routine questions eat 40-60% of support ticket volume. Here is how to let AI handle them automatically — using your own website content as the knowledge base.

How AI auto-replies work

Modern AI auto-reply systems do not use template matching or keyword triggers. Instead, they use large language models (like Gemini or GPT) combined with a knowledge base — a body of content that tells the AI what your product actually does, what your policies are, and how to answer common questions.

When a customer sends a message, the AI searches the knowledge base for relevant content, then generates a natural reply. The customer gets an accurate, conversational response — usually faster than any human agent could type.

What makes a good knowledge base

The quality of AI auto-replies depends entirely on the quality of the knowledge base. Good sources:

  • Your documentation and help center articles
  • Your pricing page (exact plan names, feature differences, limits)
  • Your FAQ page
  • Your product feature pages
  • Your terms and refund policy

Bad sources: internal wiki pages with informal tone, pages with outdated information, pages with competitor comparisons you don't want surfaced.

Step 1 — Connect your site as a knowledge base

In Talki, go to Settings → AI. Enter your website URL. Talki crawls your site and indexes the content. The crawl takes a few minutes depending on site size.

You can add specific URLs if you only want certain pages indexed — for example, only your docs and pricing page.

Step 2 — Enable AI auto-replies

Toggle AI auto-replies on. From this point, Gemini reads every incoming customer message and checks it against your knowledge base. If it finds a relevant answer with enough confidence, it replies automatically. If not, the ticket goes to your agents.

Step 3 — Review and tune

For the first week, review AI replies in the inbox. Look for:

  • Correct answers — the AI found the right content and replied accurately
  • Missing answers — the AI said it could not help, but the answer exists on your site (add that content to the knowledge base)
  • Wrong answers — the AI replied with outdated or incorrect info (update the source page)

What the AI will and will not handle

AI handles well

FAQs, how-to questions, pricing questions, feature availability, documentation lookups, policy questions (refunds, shipping, account limits).

Route to agents instead

Account-specific issues (wrong charge, account hacked, specific order problem), anything requiring action on your backend, emotional or escalated conversations.

AI conversation summaries — for tickets that do reach agents

When a ticket does escalate to a human, the agent should not have to read a 20-message thread to understand what happened. Talki's one-click summary reads the full conversation and returns three lines: the issue, the current status, and the recommended next action.

This cuts agent ramp-up time from 3-5 minutes to under 30 seconds.
