A free AI chatbot plan is not a cheaper version of the real thing. It is a measuring instrument with a small tank. Used carelessly, it produces a vague feeling that the assistant was "quite good". Used deliberately, it answers two or three specific questions before you spend a cent.
The difference is whether you set it up as an experiment. That means deciding in advance what you are testing, where you are testing it and what result would change your mind.
SpideyChat's Free plan gives you one assistant and 100 messages a month with no credit card. This post is about spending those 100 messages on evidence rather than curiosity.
The honest limits, first
A hundred messages is a sample, not a month of trading. If visitors have back-and-forth conversations, it may cover only a few dozen of them. That shapes what the test can tell you.
| A free test can show | A free test cannot show yet |
|---|---|
| Whether visitors actually open and use the chat | Your true monthly volume on a busy site |
| The kinds of questions they ask | A reliable conversion rate from chat to paid work |
| Whether answers match your own content | Seasonal patterns across a year |
| Which questions your content cannot answer | How the assistant performs on every page at once |
| How long you really spend teaching it | The value of features listed on paid plans |
That last row matters. On the pricing page, the website crawler and lead capture are listed from Starter upward, and the support ticket inbox from Pro. So a free test is mostly a test of answer quality and visitor behaviour, taught by describing your business, uploading documents and adding question and answer pairs. Revenue proof comes later.
Design the experiment before installing anything
Write these down somewhere you will see them in a month. It takes ten minutes and it is what separates a test from a trial you forget about.
- The question. For example: "Do people on our pricing page ask things the page does not answer?"
- The page. One or two pages with genuine buying intent. Not the whole site. A small allowance spread across your blog will tell you nothing.
- The content. Teach the assistant only what is true and current: a plain description of the business, your price list as a document, and 15 to 20 question and answer pairs for the things customers ask most.
- The success line. Pick something observable. "At least 20 conversations, at least three quarters answered correctly from our content, and at least five questions we had not written down."
- The review date. Thirty days out, in the calendar.
One more decision belongs here: what you will change during the test. The honest answer is very little. If you rewrite the welcome message on day 4, add 30 answers on day 10 and move the assistant to a different page on day 18, the result at day 30 describes none of those setups. Fix obvious errors when you see them, keep a note of each fix and leave the rest alone until the review.
Reading the conversations
When the review date arrives, read every conversation. With a free allowance there are few enough that this is realistic, and it is the whole point.
Mark each one with a simple tag: answered correctly, answered but poorly phrased, said it did not know, or should have gone to a person. The third tag is not a failure. A grounded assistant is meant to say so when your content has no answer, instead of inventing one. It looks something like this:
Visitor: Do you do weekend appointments for new patients?
Assistant: I don't have details about weekend appointments in the information I've been given. If you leave your name and the best way to reach you, I'll make sure the team gets back to you about availability.
That exchange is useful twice. The visitor gets an honest reply, and "weekend appointments" appears in your unanswered questions list. If it appears five times in a month, your website has a gap that is costing you, whatever you decide about the assistant. What to do when your agent keeps saying I don't know covers how to turn those gaps into answers.
Signals worth acting on
After the review, you will usually land in one of these places.
- Nobody used it. Either traffic on that page is too low or the welcome message is invisible. Try a clearer welcome message or suggested prompts for another month before concluding anything. If the page genuinely gets a handful of visitors, a paid plan is hard to justify.
- People used it, answers were weak. This is a content problem, not a product verdict. Add the missing answers and run a second month.
- People used it, answers were good, allowance ran out. That is the strongest free-plan result there is. You have evidence of demand and accuracy, and a paid plan's job is to add capacity and lead capture.
- Lots of questions needed a person. Your enquiries may be more complex than a website assistant should handle alone. Look at whether handover to a human would cover it, or whether the enquiry form is the right tool.
What the free test cannot settle
Be careful not to stretch a small sample into a big claim. Twenty conversations will not tell you how many jobs the assistant will win, and a quiet month may simply be a quiet month. Nor does the Free plan tell you how the crawler handles your site or how captured leads flow into your follow-up routine.
It also cannot tell you much about your team's side of the job. On a free test you will read a few dozen conversations. At full volume you might read several hundred a month, and whether anyone has time for that is a question only a paid month answers.
Treat the free result as permission to run a properly measured paid month, not as proof of return. The free trial test plan lays out a longer test for when you get there.
Start the test this afternoon
Pick your single highest-intent page and write your success line on a sticky note. Then sign up for the Free plan, teach the assistant from a short description, your price list and your 15 most common questions, and install it on that one page only. Put the 30-day review in your calendar before you close the tab. When the date comes, read every conversation and sort it into one of the four tags above.
