Key Features

Source-grounded answers

Answers are pulled directly from your website pages, PDFs, and documents and include links or citations to the exact source passage.

Refuses to guess

If an answer isn't present in the indexed sources, the agent explicitly says it doesn't know and shows the closest sources rather than inventing information.

Lead capture, summaries, and handoff

Every conversation can capture leads, produce summaries for the team, and automatically hand off hard questions to a human when needed.

Multi-source ingestion & knowledge graph

You can add website URLs, upload PDFs and documents, and ChatFast cleans and links content into a graph knowledge base.

Playground testing

A testing playground lets you ask real customer questions, inspect answers, trace citations, and verify behavior before going live.

Simple embed deployment

Deploy an agent with one embed snippet placed on your site; no additional code required beyond the snippet.

Conversation analytics

Built-in dashboards show what visitors ask, where answers fall short, and how many leads each conversation captures.

Multilingual support

Agents support hundreds of languages and reply in the language the customer writes in.

Frequently Asked Questions

Will it make answers up?
No. If the answer isn't in your sources, the agent says it doesn't know, shows the closest sources, or hands the conversation to your team with a summary and the customer's contact details. It never guesses.
My content is a mess — spread across a website, PDFs, and old docs. Will it still work?
Yes. ChatFast crawls your site, ingests your files, cleans out the noise, and links everything into one knowledge base. You don't need to reorganize anything first.
How much work is setup? I don't have a developer.
Create an agent, paste your website URL or upload documents, and test it in the playground — it takes minutes. The only code involved is one embed snippet you paste into your site.
Does it speak my customers' language?
Yes. Agents support hundreds of languages — English, Spanish, French, German, Japanese, and more — and reply in whichever language the customer writes in.
Can it do more than answer questions?
Yes. Agents capture leads, trigger forms, and hand off to a person when needed — and they can connect to your apps to take action, like booking appointments, checking inventory, or creating tickets.
My website changes all the time. Will answers go stale?
Website sources stay aligned with your pages as they change, and you can re-import or replace documents anytime.
How is this different from pointing ChatGPT at my site?
General chatbots answer from general training and can't show where an answer came from. ChatFast answers only from your approved sources, cites the exact page or passage, and refuses to guess.

Getting Started

  1. 1 Step 1: Add your sources by pasting your website URL or uploading PDFs and documents so ChatFast can ingest and build a knowledge graph.
  2. 2 Step 2: Test your agent in the playground to ask customer questions, inspect answers, and trace citations before going live.
  3. 3 Step 3: Embed the floating widget snippet on your site to launch the live agent that captures leads and hands off to your team.
