Search for a free AI chatbot for your website and you will find the word "free" on almost every pricing page. It means three different things. Some tools have a free plan you can keep for ever, with small limits. Some give you a trial that ends after a week or two, with or without a card. And a few let you build and test a bot for free but ask you to pay before it goes on your site.
Below is what each kind usually includes, where it stops, and how to get a real answer out of it. Free plans and trials change often, so read a tool's own pricing page and terms before you sign up. TailGPT's details are as of 4 October 2026.
What does "free" actually mean on a chatbot pricing page?
It means one of three arrangements, and the difference matters more than the price beside it.
- A permanent free plan. No end date, but a small monthly allowance and often a condition: who may use it, how long an idle bot is kept, or what the free plan does not include.
- A time-limited trial. The full product, or most of it, for 7 or 14 days. Some ask for a card up front and start charging when the trial ends unless you cancel. Others ask for nothing.
- A build-and-test trial. You can read your site, set up a bot and question it in the dashboard, but the code that puts it on your website comes with a plan. This is how TailGPT's free trial works.
None of these is a trick. Each answers a different question: "is this good enough to leave running for free?", "is the paid product worth it?", or "does it answer well from my own pages?".
What does a permanent free plan usually limit?
Almost everything that costs the vendor money, kept small enough that a business outgrows it. A free plan on a website chatbot is real, and it is useful, but read these five limits before you build on one.
Answers a month
Free plans usually come with a small monthly allowance, often somewhere between a few dozen and a hundred answers. Many count in credits rather than questions, and a credit is not always one answer: some tools charge one credit for an answer from a smaller model and several for an answer from a larger one, and a free plan may offer only a limited choice of models. Work out how many real answers the allowance buys, not how many credits. Message credits vs questions explains the difference.
How much of your website it reads
The content allowance on a free plan is often a few dozen pages or a megabyte or so of text. Check what the tool calls a page, too. On some tools a "page" is a fixed amount of text, a few thousand characters, so one long web page counts as several. Either way, it is usually a slice of a business website rather than the whole of it.
Who may use it
Some free plans are offered for personal use, or for trying the product, rather than for running a business website. That wording sits in the plan description or the terms, and it is worth reading before your bot starts answering customers.
How long an idle bot is kept
Some free plans delete a bot that has had no activity for a couple of weeks. A quiet fortnight in the off season is enough to lose the setup you made.
What a "conversation" means
Some free plans belong to live chat products. Their free allowance counts conversations that a person on your team answers, and the AI part has a small one-off starter allowance or none, with a separate paid plan for a monthly amount. That is a free live chat inbox, which still needs somebody to answer it, rather than a free AI chatbot.
How do time-limited trials differ, and do they need a card?
They differ mainly on length and on whether you hand over a card first. Most tools built to answer from a website offer a trial rather than a free plan, usually for 7 days and sometimes for 14.
- Card required. You enter a card to start, and the plan begins charging when the trial ends unless you cancel. Some of these tools say plainly on their pricing pages that there is no free plan at all.
- No card. You get the trial without payment details. When it ends, the account either stops or drops to a free plan with smaller limits.
- Not stated. Some pricing pages offer a trial without saying whether a card is needed. Find out before you start, not on day eight.
Two more things are worth checking. Some trials give you the full product and some give you one plan, so you may be testing features you will not buy. And on tools billed per resolved conversation, a trial may include resolutions free that you will pay for once it ends, so a quiet trial week tells you little about a busy month's bill.
A card-required trial is not worse, but put its end date in your calendar the day you start.
What does TailGPT's free trial include?
TailGPT's free trial is for building and testing, not for running on your website. An account that has never had a plan can add one website, have up to 500 of its pages read, create one chatbot and ask it 20 test questions in the dashboard. No card is needed to sign up.
What it leaves out is deliberate. The trial cannot re-read the website, cannot upload documents, and cannot put the chatbot on your site: the one line of code that does that appears once you choose a plan. As of 4 October 2026, plans start at ₹4,000 a month on Starter; the pricing page has the rest.
The 20 test questions go through the same answering steps your visitors' questions would. The bot answers only from the pages it read, and when they do not cover a question it says plainly that your website doesn't cover it instead of guessing. That answer still uses one of the 20. A question it refuses, such as an attempt to give it orders, does not use one of the 20.
How do the free options compare side by side?
Here is each kind of free in one table. The TailGPT row is as of 4 October 2026; for any other tool, check its own pricing page.
| Kind of free | Card needed? | What you usually get | What to check |
|---|---|---|---|
| Permanent free plan | Usually not | A small monthly allowance of answers or credits, and a small slice of your content | Who may use it, whether idle bots are deleted, what visitors see at the limit |
| Time-limited trial | Some yes, some no | The paid product, or one plan, for 7 or 14 days | The end date, whether a card is charged, which plan you are really testing |
| Free live chat plan | Usually not | A number of conversations a month that a person on your team answers | Whether any AI answers are included each month, or only once |
| TailGPT free trial | No | 1 website, up to 500 pages read, 1 chatbot, 20 test questions | Cannot go on your live site, re-read the site or take documents until you choose a plan |
What can you learn from each kind of free?
Each kind answers one question well and leaves others open.
A free plan tells you about the product, not the bill
A permanent free plan lets you take your time with the dashboard and see an answer or two from your own content. What it rarely tells you is how the bot behaves on your whole website, because a few dozen pages or a megabyte of text is a slice of most business sites. It also does not tell you what a normal month will cost, because a normal month for a business is many times a free allowance.
A time-limited trial tells you about the paid product, if you are ready
A 7-day trial on the full plan is the closest thing to the real product. The risk is time: most people sign up on a Tuesday, get busy by Thursday and reach day seven having asked six questions. Start it on a day you have an hour and a list ready.
A build-and-test trial tells you about the answers
TailGPT's trial reads up to 500 of your real pages and lets you question the result. That is the test that matters most for a website chatbot: does it answer correctly from your pages, and does it admit when they say nothing? What it cannot show you is how real visitors use it, because it never meets them. You will learn that in the first weeks after the bot goes live.
Can a business really run a chatbot on its website for free?
Rarely, and it is better to know that before you build anything. The free plans above are sized for a try-out. Fifty answers might be a slow afternoon for a shop in Pune during a sale. A coaching institute in admission season can see more questions than that before lunch. When the allowance runs out, the bot usually stops answering, and on some tools visitors see an error message instead of an answer.
There are conditions too. A plan offered "for personal use" is not offered for your business. A bot deleted after a couple of weeks of inactivity can vanish in a quiet fortnight. A free live chat plan still needs a person answering the chats.
Free plans are a sample, and a good one. But a free bot left on a business website will usually be outgrown in the first busy week, so pick the tool whose paid plan you would be happy to pay for. AI chatbot pricing: what you are actually paying for explains the units those paid plans are priced in.
How do you get the most out of a free option?
Treat it as a test with a list, not a browse. Five habits make the difference.
- Use your own website. A demo bot trained on the vendor's content proves nothing about yours. Point the tool at your real pages, the ones a customer would read.
- Bring real questions. Copy twenty questions from your inbox, your WhatsApp chats or your phone notes. Use your customers' words, not your own.
- Ask what your pages do not cover. A discount you have never offered, a branch you do not have, a service you do not sell. The tool that says it does not know is the one you can leave running overnight.
- Write the answers down. Keep a simple sheet: question, answer, right or wrong. It turns a vague feeling into a decision.
- Check the end of the road. Find out what happens at the limit, and when the trial or plan ends: does the bot stop, is anything deleted, does a card get charged?
Our AI chatbot free trial checklist turns these into a seven-day plan that works for any tool, and the six questions to ask before you buy an AI chatbot are worth putting to the vendor alongside it. How to test a chatbot's answers before you buy covers the answer test in more depth.
Which kind of free should you choose?
Choose by what you need to find out first.
- You want to learn how chatbots work, with no deadline: a permanent free plan suits you. Read its conditions first: who may use it, and how long an idle bot is kept.
- You already like a tool and want to test the paid version: a time-limited trial, started on a day you can give it an hour.
- You need live chat with people answering: a free live chat plan is built for that, usually with AI answers sold on top.
- You want to know whether a bot answers well from your own website before paying, without a card: TailGPT's free trial reads up to 500 of your pages and gives you 20 questions to find out.
