Features

Everything you need, nothing you don't

Build, train, test and deploy — all from one dashboard.

Answers from your data

Paste your website URL or upload PDFs. We crawl, split and index everything, then answer only from what you taught it — social networks excluded.

Smart forms, not dumb bots

Define variables with allowed values. The AI extracts several details from one sentence, recaps them, then sends everything to your webhook.

Voice calls

Let customers talk instead of typing. A realtime voice agent answers in their language, with the same knowledge — hands free.

One line to install

Copy the embed snippet, paste it before </body>. Your brand color is applied everywhere automatically, with a live preview.

Prospection built in

Find businesses around a point on the map, filter by rating and review freshness, and train a demo chatbot on their website in one click.

Multiple chatbots

One chatbot per website, each with its own knowledge base, widget, intents and message counter. Switch between them in one click.

How it works

Three steps. Five minutes.

No developer, no API wiring, no waiting on a quote.

1

Feed it

Add your website URL, upload a PDF, or import plain text. We crawl pages (even JavaScript-rendered ones) and clean out the noise.

2

Train it

One click splits everything into chunks, creates the embeddings, and stores them. Re-train anytime your content changes.

3

Launch it

Embed the widget on your site, share the demo link with your client, or connect a WhatsApp number. It answers immediately.

WhatsApp Bot

Pricing

Simple, transparent pricing

Start free, upgrade when your business needs more.

No subscription anymore. There is no monthly plan, no chatbot limit and no message limit. You create your account for free and you pay only what your chatbots actually consume: every AI answer is deducted from your AI credits balance (real API cost + platform margin). When the balance reaches $0 the chatbots simply pause until you top it up — nothing is lost, nothing is blocked by a plan.
