Illustration: a customer asks how long shipping to Canada takes; the assistant searches the store's knowledge, answers from its Shipping times FAQ, then for a question about Bitcoin finds no match and offers a contact form.

The questions your team answers every day

How do I reset my password?Can I exchange a sale item?Are you open on Sundays?Do gift cards expire?How do rewards points work?What sizes do you carry?Can I cancel my subscription?Is express shipping available?

00The idea

Most support bots guess. Yours answers from what you've actually written, and says so when it can't.

  1. 01

    Grounded

    Answers are written only from the FAQs, documents and pages you approve. Your content is the source of truth, not the open internet.

  2. 02

    Transparent

    Every answer records the sources behind it, and customers can rate each reply. You see exactly what was said, and why.

  3. 03

    Human when it matters

    When the answer isn't in your content, the assistant says so and collects the customer's details for your team.

01How it works

Live on your website in three steps.

No training runs, no flow builders, no scripts to maintain. Your content is the source of truth.

  1. 1Step 1 of 3

    Add your knowledge

    Write FAQs, upload PDF or text documents, or import public pages from your website. Each source is processed in the background and becomes searchable within moments.

  2. 2Step 2 of 3

    Test it like a customer

    Ask the questions your customers ask. See which sources every answer used, and which questions fall back to your team instead.

02Features

Everything you need to run support

One dashboard for your knowledge, conversations, handoffs and results. Built for small teams who don't have time for complicated tools.

  • Conversation inbox

    Read every conversation with the sources each answer used. Search by message text, filter by status, and see what customers rated.

  • Human handoff

    Unanswered questions become requests with the customer's email, a live badge and optional desktop alerts.

  • Overview analytics

    Answer rate, ratings, response time and the questions it couldn't answer, so you know what to add next.

  • Three ways to add knowledge

    FAQs, PDF and text documents up to 10 MB, and public web pages imported by URL.

  • A widget that feels like yours

    Your name, greeting and colour. Loads instantly, goes full screen on phones, and only runs on the sites you allow.

Interface previews use sample data.

03Grounded answers

Built to say “I don't know.”

Generic chatbots answer anything, including what they shouldn't. Replynex AI is designed to answer from your approved content and nothing else.

  1. 01Designed to answer only from the content you added, never from guesses.
  2. 02Every answer records the sources it used, visible in your inbox.
  3. 03If the answer isn't there, it says so and offers a person instead.
  4. 04Instructions hidden in documents or messages are treated as data, not commands.

Answer with its sources

Not found

Fallback + contact form

Every question takes one of two paths. There is no third path where it guesses.

  • Isolated workspaces

    Row-level security keeps each business's knowledge and conversations separate, verified by automated tests.

  • Private documents

    Uploads live in a private bucket and are checked by their actual contents, not their names.

  • Only your websites

    Choose the sites allowed to display your assistant. Public endpoints are rate-limited.

  • Privacy-minded

    No visitor accounts or tracking cookies, and logs never contain message text.

05FAQ

Questions, answered.

Straight answers about how Replynex AI works, what it costs and how your data is handled.

What is Replynex AI?

Replynex AI is an AI customer support assistant you add to your website with one script tag. It answers customer questions using only the FAQs, documents and web pages you give it, and hands the conversation to your team when it can't answer.

How does Replynex AI answer customer questions?

When a customer asks a question, Replynex AI searches your knowledge base for the most relevant passages, then a Google Gemini model writes a short answer using only those passages. Answers stream in real time, and the sources they came from are recorded with every answer.

Will the AI make up answers?

It is designed not to. The assistant is instructed to answer only from your content, and when your knowledge base doesn't contain the answer it replies with your fallback message and offers a contact form instead of guessing. No AI system is perfect, so every conversation is visible in your dashboard and customers can rate answers.

What content can I add to the knowledge base?

You can add FAQs written in the dashboard, upload PDF and plain-text documents up to 10 MB, and import public web pages by URL. Content is processed in the background and becomes searchable in seconds. Your content is used for retrieval only; it is not used to train an AI model.

How do I add the chat widget to my website?

Copy the one-line script tag from your assistant's settings and paste it before the closing body tag of your site. The chat button loads instantly, the chat itself loads only when a visitor opens it, and you can restrict which websites are allowed to display it.

What happens when the assistant can't answer a question?

It sends your configured fallback message and shows a short form so the customer can leave their email and question. The request appears in your dashboard immediately, with a live badge and optional desktop notifications, linked to the full conversation.

Is my data kept separate from other businesses?

Yes. Every workspace's knowledge, conversations and files are isolated with database row-level security, and search is filtered to your workspace inside the database. Cross-workspace access is covered by automated tests.

How much does Replynex AI cost?

Replynex AI is free during early access, with no credit card required. Paid plans with higher limits and team features are planned; their prices are shown on this page and may change before launch.

Does it work on mobile and with screen readers?

Yes. The widget and dashboard are responsive, the chat goes full screen on phones, and the pages are checked against WCAG 2.1 AA accessibility rules with keyboard-only navigation tests.
