How ChatFast differs from other AI agents.
Many AI agent platforms are built for large support teams and take a project to launch. ChatFast is built so a business sees results within days, without one.
- 01
Most questions are resolved before they reach your team.
ChatFast agents resolve 97% of conversations on their own. Your team gets the few that need a person, each with the full conversation attached.
- 02
More of your visitors become leads.
The agent answers a buyer’s question on the spot, asks for contact details, and sends them to your team. It does the same at night and on weekends.
- 03
You are live in days.
One person can connect the website and files, test the answers, and paste one snippet. There is no demo call and no implementation project, and every price is listed.
- 04
The agent gets better the longer it runs.
It lists the questions it could not answer and drafts a reply for each. Approve a draft, and the next customer who asks gets the answer.
The first difference, shown. One pricing question, asked three ways. Only one customer gets a correct answer straight away.
Contact form
The question sits in an inbox until someone has time to answer it. The customer may have bought elsewhere by then.
Generic chatbot
It replies at once, but not from your documents, so it can sound sure and still be wrong.
ChatFast agent
The customer has the correct answer in seconds, taken from your own pricing document. What your documents do not cover goes to your team.
What to expect, in plain terms.
How the agent behaves, what happens to your data, and what it costs. You can check each of these during the free trial.
- 01HandoffA person takes over when one is needed.
- AI replies stop, and the conversation reaches your inbox with the full transcript attached.
- 02VoiceCustomers can talk to it out loud.
- Visitors can speak with the agent in the chat on your website. The call is transcribed as it happens.
- 03LanguagesIt replies in your customer’s language.
- The agent answers in the language a customer writes in, or you can pin one language for every conversation.
- 04Your dataYour content is never used to train models.
- Your documents and conversations power your own agents and nothing else.
- 05ModelsLeading models, with nothing to manage.
- ChatFast routes each request to a model such as Claude, GPT, Gemini, or Grok. You choose the reasoning level.
- 06CostPricing you can work out in advance.
- A message uses 5 credits with Standard reasoning, or 10 with Advanced on Elite. You can limit how many one visitor sends.
From your knowledge to a live agent in four steps.
Connect your content, check the answers, paste one snippet, then improve the agent from real conversations.
01Connect
Add your knowledge.
Point the agent at your website, help center, PDFs, and files, then choose what it should answer, collect, and escalate.
02Test
Check answers before customers do.
Ask real support and sales questions in the playground, and correct anything that falls short.
03Go live
Install one snippet.
The agent starts answering visitors and capturing the details your team needs to follow up.
04Improve
Learn from real conversations.
See what customers ask, where answers were weak, and who left their details, then strengthen the knowledge behind them.
What can a ChatFast agent do?
It answers questions from the website, help center, PDFs, and files you connect. In the same conversation it can collect contact details and form fields, send an email, call your API, or open a link, and it hands off to your team when a person is needed.
What happens when the agent gets an answer wrong?
Correct it once and the correction holds. Find the conversation, then add a Q&A entry that pairs the question with the exact reply you want. The agent uses that entry from then on, and you decide what it says when a question falls outside your sources.
How does the agent stay current when our pricing or policies change?
Update the page or document, then re-index that source. The agent answers from the new version. For details that are not written down anywhere, add a Q&A entry.
Does it replace our support team?
No. The agent handles the repetitive questions and passes everything else to a person. When it hands off, AI replies stop and the conversation, transcript, and any captured contact details arrive in your team inbox.
Is our content used to train AI models?
No. We do not train or fine-tune foundation models on your documents, your messages, or any other data in your workspace. It is used only to power your own agents.
What does it cost as conversations grow?
Each message a customer sends uses credits: 5 with Standard reasoning, or 10 with Advanced reasoning on the Elite plan. Cost follows real conversation volume, and you can limit how many messages one visitor sends within a set time.
Which AI models power the agent?
ChatFast routes each request to a leading model, including Claude, GPT, Gemini, and Grok, so you never manage models yourself. You choose the reasoning level for each agent: Standard or Advanced.
Can the agent reply in other languages?
Yes. The agent replies in the language the customer writes in, or you can pin one language for every conversation.
