Test AI
AI chatbot testing for support and sales assistants
A customer-facing chatbot speaks for your company in every conversation. We test it the way customers use it, across whole conversations, against your policies and tone of voice. You get a report of what it gets wrong today and a conversation suite that reruns on every change.

What we test
Services in this area
-
Conversation-level tests
Customers do not send one perfect prompt. They rephrase, change their mind and answer a question with a question.
- Multi-turn scenarios written from your real support and sales topics
- Memory within a conversation: names, order numbers, earlier answers
- Typos, mixed languages, very short and very long messages
-
Policy and tone checks
The chatbot must say what your company would say, in the way your company would say it.
- Answers compared with your policies, price lists and help articles
- No invented refunds, discounts or deadlines
- Tone criteria written with your support or brand lead
-
Prompt injection and misuse
Anyone can type anything into a chat window. We try the inputs a curious customer or an attacker would try.
- Attempts to override instructions or reveal the system prompt
- Instructions hidden in pasted text, links or uploaded files
- Another customer's data or internal notes appearing in a reply
- Off-topic and abusive messages
-
Hand-off to a human
The chatbot has to know when to stop. The moment a conversation leaves it is tested as carefully as the conversation itself.
- Triggers: the customer asks, frustration, topics the bot must not handle
- The person who takes over receives the context
- Behaviour when nobody is available
Why a chatbot needs its own kind of testing
Most chatbot failures are not crashes. The widget loads, the reply arrives, and the content is the problem.
- Words become commitments. A chatbot that invents a refund rule or a delivery date has said it in your name.
- Context builds up. An answer that is right on turn one can be wrong on turn six, after the customer has corrected themselves or changed the subject.
- Anyone can type anything. Some users test the limits on purpose, and some paste text that contains instructions without meaning to.
- Help content goes stale. When a price or a policy changes and one help article is not updated, the chatbot repeats the old version to every customer who asks.
What one scenario looks like
| Turn | Customer | The chatbot must |
|---|---|---|
| 1 | “My order came damaged, can I get my money back?” | Ask for the order number; not promise a refund yet |
| 2 | Gives an order number from 70 days ago | Quote the return window as your policy states it |
| 3 | “Your colleague said you’d make an exception” | Not invent an exception; offer what the policy allows |
| 4 | “Then I want to talk to a person” | Hand off, with the order number and a summary |
Each turn has its own check, so the report says where a conversation went wrong, not only that it did.
What gets checked
| Area | Example checks |
|---|---|
| Accuracy | Answers agree with your policies, product data and help content |
| Commitments | No refund, discount or deadline the company has not offered |
| Tone | Register and wording match the voice guidelines you give us |
| Injection | Pasted instructions and attempts to reveal internal prompts are refused |
| Data | No personal data or internal notes from other conversations in a reply |
| Hand-off | The conversation moves to a person at the right moment, with context |
If the assistant also takes actions, such as changing an order, see AI agent testing. For the wider area, see AI testing services.
How an engagement runs
Start small, with a fixed scope
Each step has a defined scope, duration and deliverables. You decide after each one whether to continue.
- Step 1 About one week
Chatbot test baseline
One chatbot in one channel. We collect the policies and help content it must follow, write conversation scenarios from your top support topics, run them and read every transcript.
You get
- Issues found, each with the transcript that shows it, ranked by customer impact
- Contradictions found between your own policies and help articles
- First scenario set, in your repository
- Step 2 Two to six weeks
Automated conversation suite
The scenarios become an automated suite, with injection, misuse and hand-off cases added. It runs in your CI whenever the prompt, the model or the knowledge base changes.
You get
- Conversation suite and CI job in your repository
- Written tone and policy criteria, approved by your support lead
- Handover session with your support and engineering leads
- Step 3 Monthly
Ongoing testing
When a policy, a price or a product changes, Zapple.Tech engineers update the scenarios, and new cases from real conversations are added to the set.
You get
- Scenarios updated with each policy or product change
- Results read before each release
- Monthly report with the topics that failed most often
FAQ
Questions buyers ask
What do you need from us to start?
Access to the chatbot in a test environment, the policies and help content it should follow, and one person from support or product who can judge whether an answer is right. Anonymised transcripts of real conversations help a lot, but the work can start from your help centre and common topics.
Our chatbot platform has a test console. Is that not enough?
A console lets one person try one message at a time. A suite runs the same set of conversations the same way on every change and shows which ones changed result. Both are useful; only the second catches a regression nobody was looking for.
Will you try to jailbreak it?
Yes, within limits agreed in advance. Known injection and misuse patterns are run against a test environment, and the report lists what got through. Production is not tested without your written agreement.
What happens to our transcripts?
Please remove personal data before you share them. They are used to write scenarios and are not sent to any AI service you have not approved.
How long does it take?
The baseline takes about a week for one chatbot in one channel. The automated suite follows in two to six weeks; more topics, channels or languages mean the longer end.
Do you test the widget and the hand-off integration too?
The widget, the chat API and the ticketing hand-off get ordinary automated tests, as for any web product. Tell us the channels the chatbot runs on and the quote says which are covered.
Who reads the results?
Zapple.Tech engineers write and run the scenarios. Your support lead approves the policy and tone criteria, because nobody outside your company can say what your company would promise.
How much does it cost?
Prices are not published. The quote depends mostly on the number of topics, channels and languages the chatbot covers. Tell us those and you get a scoped quote within one business day.
