ChatFast
Build AI agents that answer from your website, help center, and PDFs — then collect leads, call your API, or hand off to your team.
Pick ChatFast if customers ask the same product, billing, and policy questions daily and they need to see the source behind each answer. Citation-first replies and correct-once Q&A entries are what actually cut ticket volume. Skip it if you want a flat-fee FAQ widget — message credits mean cost scales with conversation volume.

Skip ChatFast if your site answers the same handful of FAQs at high volume and you want a flat monthly fee rather than paying 10-25 credits per customer message.
Each customer message costs 10 credits in standard mode and 25 in advanced, so a busy support widget can burn through a monthly allowance quickly.
ChatFast sits at the higher end of the AI agent category: Basic is $35/mo for 3,000 credits, Premium $100/mo for 10,000, and Elite $325/mo for 35,000 credits plus advanced reasoning and branding removal. That's above flat-fee widget chatbots aimed at simple FAQ duty, but below enterprise agent platforms that quote custom contracts. The right tier depends on your monthly message volume, not your headcount.

What is ChatFast?
ChatFast — Build AI agents that answer from your website, help center, and PDFs — then collect leads, call your API, or hand off to your team. Best for Support teams with large, messy documentation that need cited answers, Sales teams qualifying and capturing leads inside the chat, Knowledge teams building internal or research agents over PDFs and help centers.

ChatFast is an AI agent platform for support, sales, front-desk, and internal knowledge teams. Instead of a generic chatbot that guesses, you connect your own sources — website pages, help center, PDFs and files (scanned documents included), notes, and Q&A entries — and the agent answers from them, citing where each reply came from. When the answer isn't in your documents, it says so rather than inventing one. Setup follows four steps: connect your content, test real support and sales questions in a playground, install one snippet, then refine from live conversations. Corrections hold — add a Q&A entry pairing a question with the exact reply you want and the agent uses it from then on. Changed a pricing page? Re-index that source and answers reflect the new version. Beyond answering, agents collect work email, company, team size, and custom form fields inside the chat, then trigger an email, an API call, or a webhook. When a person is needed, AI replies stop and the full transcript plus captured contacts land in your team inbox. An insights dashboard shows conversation volume, contacts captured, handoffs, and low-confidence answers. October 2026 added voice conversations, suggested follow-up questions, and emoji reactions. Every paid plan includes unlimited agents, so each job gets its own. Requests route across Claude, GPT, Gemini, and Grok with Standard or Advanced reasoning per agent. It targets messy, multi-source knowledge bases where citations and human handoff matter more than a low monthly ceiling.

Behind the verdict
The first thing I check with any support agent is what it does when it doesn't know. ChatFast's answer is to say so and escalate, which is the behavior that keeps you out of trouble with customers. Where it earns its keep is messy, multi-source knowledge. If your truth is scattered across a pricing PDF, a help center, and a handful of policy pages that change quarterly, re-indexing beats re-training every time. The playground is undersold in the marketing: testing edge-case billing questions before launch is where most teams catch their real gaps. When to reach for it: support with high repeat-question volume, sales chats that need to qualify and capture leads, and internal research agents over document piles. Voice conversations, added in October 2026, widen the front-desk use case. When to pass: a single-document FAQ doesn't need reasoning or handoff, and high-volume sites should model credit burn before committing — each customer message spends 5 credits on Standard or 10 on Advanced (Elite plan). The October 2026 cut of up to 60% in per-message credit usage softens that math considerably. Compliance teams that need one foundation model pinned should look elsewhere; ChatFast routes across Claude, GPT, Gemini, and Grok, and you don't manage models yourself. You pick Standard or Advanced reasoning per agent, and that's the lever you get. The closest alternative is a per-seat helpdesk with a bolted-on AI. If you want ticketing and the agent on one bill, that wins on simplicity. If the agent itself is the product and citation accuracy is the point, ChatFast is the sharper tool.
Models under the hood
as of 2026-10-30
Limitations
- Usage is metered by credits, with standard and advanced reasoning modes costing 10 vs 25 credits per message.
- The agent answers only from the sources you connect, so undocumented details need a manual Q&A entry, and anything it cannot resolve is handed off to your team.
- Unlimited agents are included on paid plans, subject to fair use.

GeneratedReal-world workflow fit
Concrete scenarios for the personas ChatFast actually fits — and what changes day-one when you adopt it.
Connect the website and help center, add the refund policy PDF and pricing doc, test the ten most common questions in the playground, then paste the embed snippet on the pricing and docs pages.
Outcome: Tickets for billing and policy questions drop because the agent cites the exact help center article or PDF page, and anything it can't resolve lands in the team inbox with the transcript attached.
Configure the agent to answer product questions from the website, then collect work email, company, and team size before triggering an email to the sales team or a webhook into the CRM.
Outcome: Inbound visitors who ask for a demo become routed leads with contact details attached, instead of abandoning a contact form.
Upload the employee handbook, policy PDFs, and a set of Q&A entries, then run the agent internally so staff can ask about leave, expenses, and benefits.
Outcome: Routine policy questions get cited answers traced to a source, and unusual cases are escalated to an operator rather than answered incorrectly.
Use cases
- Answer product, billing, and policy questions from your help center and hand off what it can't resolve.
- Deploy a support agent that cites a refund policy PDF alongside your website pages.
- Build an internal HR policy agent that traces every answer back to a source.
- Capture and qualify leads inside the chat with custom questions and work email capture.
- Ingest competitor documentation for research and competitive analysis.
- Cut ticket volume by resolving common questions from help center articles.

Setup time & first value
How long it actually takes to get something useful out of ChatFast — broken out by persona, not the marketing-page minute.
Support and sales teams can go live in an afternoon once source curation is done — connecting the website and help center, testing in the playground, and installing one snippet is fast, and the vendor itself flags choosing what the agent is allowed to trust as the most time-consuming step. Internal HR agents over a handful of PDFs typically take longer, since scanned documents and policy files
Switching to or from ChatFast
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a keyword-matching chatbot: point ChatFast at the same help center and website, then retire the old scripted flows once the playground answers match.
- →From a generic LLM chat widget: connect your docs so answers cite sources rather than coming from the model's memory.
- ↗To a flat-fee FAQ widget: export your Q&A pairs and rebuild them as canned responses if you no longer need cited reasoning.
- ↗To a custom in-house agent: use the ChatFast Chat API to move conversation logic, but re-ingest your knowledge sources into your own retrieval layer.
