ChatFast

ChatFast builds website and voice AI agents from your site, help centre and files. Agents cite sources, collect leads, trigger emails or webhooks and pass chats to staff when needed.

What is ChatFast?

ChatFast is a platform for building customer-facing AI agents that answer from your own business content. You connect your website, help centre, PDFs and other files, check the answers in a test playground, and then paste a single script snippet into your site to put the agent live. Besides text chat, plans include voice minutes so the agent can also handle calls.

It targets small and mid-sized businesses that want separate agents for support, sales, a front desk or internal team knowledge without hiring developers. The details are on the official ChatFast website.

Key Features of ChatFast

Answers Grounded in Your Documents

ChatFast agents learn from websites, help centres, PDFs and files, including scanned documents. Replies can show which source they came from, and you re-index a source when your pricing or policies change.

Q&A Corrections

When an answer is wrong, you add a question-and-answer entry with the exact reply you want, and the agent uses it from then on. You also decide how it responds to questions outside your sources.

Lead Capture and Actions

Inside a conversation the agent can collect contact details and form fields, send an email, call your API, notify a webhook or open a link.

Human Handoff

When a person is needed, AI replies stop and the conversation lands in your team inbox together with the transcript and any captured details.

Voice Agents

Every plan includes voice minutes and a set number of simultaneous calls, so the same knowledge can power phone-style conversations.

Model Routing and Privacy

ChatFast picks a leading model for each request, naming Claude, GPT, Gemini and Grok among them, and you choose Standard or Advanced reasoning per agent. The company says your documents and chats are not used to train foundation models.

ChatFast Pricing

ChatFast bills in credits. Each customer message costs 5 credits with Standard reasoning, or 10 with Advanced reasoning on Elite. All paid plans allow unlimited agents under a fair-use policy, and a 14-day trial needs no credit card.

Who Should Use ChatFast?

• Small businesses that want a website agent answering support and billing questions from their own documents.
• Sales teams that need visitors qualified and contact details captured before a handoff.
• Clinics, agencies or local services that want a front-desk agent for chat and calls.
• Teams that want an internal assistant over their knowledge base.

Is ChatFast Worth It?

ChatFast has a clear pitch: accurate, source-backed answers from your own content, with simple setup and a clean handoff to people. Unlimited agents on every paid plan is generous, since you can give support, sales and front desk their own agents without paying per bot, and voice minutes are bundled rather than sold separately.

The limits are worth reading closely. The Basic plan covers roughly 600 messages a month, which suits a low-traffic site but not a busy store. Advanced reasoning and branding removal are reserved for the $325 Elite plan, and the pricing page lists only monthly prices, with no annual discount shown. If your volume is modest and you value cited answers, ChatFast is a sensible choice; high-volume teams should model their credit use first.
