The short answer
- Collect the questions customers already ask.
- Write clear PDF, CSV, or TXT files for shipping, returns, sizing, and product FAQs.
- Upload those files into the app knowledge base.
- Add your Gemini API key and test five real questions.
- Fix wrong answers in the files before you scale chat volume.
How the knowledge base works here
Live Chat & AI Chatbot. Knowledge base from PDF, CSV, TXT ($1.94/mo · $1.60/mo yearly)
Best for: Stores that can keep policy and product FAQs written and current
Files are extracted into a searchable knowledge base for the AI. The bot answers from that material through your Gemini API key (bring your own key). Uploads require a valid Gemini key. Supported formats: PDF, CSV, and TXT only. There is no OpenAI runtime, no in-chat product recommendations, no WhatsApp routing inside the widget, and no PSTN calling. Wrong or empty files produce wrong answers.
Pros
- Upload PDF, CSV, or TXT for product, policy, and business content
- AI replies from that material via Gemini API key
- Escalate to humans when the file has no answer
Watch outs
- Empty or outdated files produce bad answers
- Marketing fluff is not a knowledge base
What to upload first
| File topic | Include | Skip |
|---|---|---|
| Shipping | Zones, times, costs, cutoffs | Vague "fast shipping" claims |
| Returns / refunds | Windows, conditions, how to start a return | Legal walls of text nobody can parse |
| Sizing / fit | Charts, measurement tips, exchange rules | Guessy style advice |
| Product FAQs | Materials, care, compatibility | Sales slogans |
Training checklist
- Export or copy the last 20 support questions from email, WhatsApp, or chat.
- Group them into shipping, returns, product, and account topics.
- Write one file per topic (PDF, CSV, or TXT) with short, direct answers.
- Upload the files into Live Chat & AI Chatbot.
- Activate AI with your Gemini API key.
- Assign at least one teammate who can take escalations.
Tip
Real questions → PDF/CSV/TXT files → upload → Gemini key → test → fix files → go live.
The knowledge base needs an owner, not just a launch
A knowledge base built once during setup goes stale the moment a shipping rate, return window, or product line changes. Assign one person as the actual owner of those files, with a habit of updating them the same week any policy changes. not "whenever someone remembers." A chatbot confidently repeating a return window you retired three months ago is worse for trust than admitting it does not know.
How to test before you go live
Ask the bot the same questions a tired customer asks at 11pm:
- How long does shipping take to my region?
- How do I start a return?
- Does this product include X?
- What if the item arrives damaged?
- Can I change my order after checkout?
If the answer is wrong, edit the file. If the answer does not exist, add it or make sure handoff to a human is obvious. Channel mix: live chat vs AI chatbot on Wix.
When not to enable AI
- You only have homepage marketing copy to upload
- Prices, shipping rates, or return windows change weekly and nobody updates files
- Custom or made-to-order work needs a human every time
- You treat the knowledge base as a one-time upload forever
Watch out
Do not enable AI on an empty knowledge base. You are publishing a guessing machine on the product page.
What to measure
- Wrong-answer count in the first week
- Topics that always escalate (those files need work or should force handoff)
- Time since each knowledge base file was last updated
- Share of chats closed without a human
Pricing reminder: US$1.94/mo monthly or US$1.60/mo yearly. Contact Ichonic if you want help structuring the first file set.
Key takeaway
The knowledge base is the product. The chatbot is just the mouthpiece.
Train Live Chat & AI Chatbot on your files
Upload shipping and returns text first. Add your Gemini key. Test five questions before you leave AI live overnight.
Open App Market listingFAQ
Can I train the chatbot with a PDF?+
Yes. Upload PDF, CSV, or TXT files into Live Chat & AI Chatbot, then activate AI with your Gemini API key. The bot answers from those files. Keep shipping, returns, and product FAQs current or answers go stale.
How do I build an AI chatbot with a knowledge base on Wix?+
Install Live Chat & AI Chatbot, upload PDF, CSV, or TXT files that cover products, policies, and business FAQs, then activate the AI chatbot with your Gemini API key. Test answers before you leave the widget live unsupervised.
What file types does the knowledge base use?+
In the app upload dialog you can add PDF, CSV, and TXT files. Use clear written content for shipping, returns, sizing, and product FAQs. Knowledge base uploads also require a valid Gemini API key.
Why did the bot give a wrong answer?+
Usually the knowledge base is missing, outdated, or contradictory. Fix the source file and retest. Do not paper over a bad file with a friendlier tone.
Can the knowledge base replace human support?+
No. It covers repeat questions. Refunds, damaged orders, custom work, and angry customers still need a human path. Live Chat & AI Chatbot supports escalation to agents.
How much does the app cost while I train the knowledge base?+
US$1.94 per month on monthly billing, or US$1.60 per month on the yearly plan. Confirm the live App Market block before you subscribe.
Who should be responsible for keeping the knowledge base files updated?+
Assign one specific person as the owner, with a habit of updating the relevant file the same week any policy or product change happens. A knowledge base built once at launch and never revisited will confidently give outdated answers, which is worse for trust than the bot admitting it does not know.
