What it can do
Lightweight widget
29 KB gzipped, including the product block (measured 06.10.2026). Runs in an isolated Shadow DOM and won't affect your site's styles.
Knowledge base with source
Answers are based on your pages and documents (PDF, DOCX), and the bot shows where each answer came from.
Request form right in the chat
When a customer is ready to share their contact details, the bot displays a form. The request appears in your dashboard and, if configured, in your CRM and Telegram.
Styled to match your site
Light or dark theme, custom colors, rounded corners, font, window size, and button label.
Operator in Inbox
You can take over a complex conversation; the operator sees the full history.
Tracking with consent
You can enable visitor analytics and heatmaps, with a consent banner.
Traffic source in the conversation
See which ads and pages visitors came from—and which orders resulted.
Customer profile
Returning buyers don’t need to repeat their size or branch — the bot remembers if you’ve enabled this.
Protection from manipulation
The bot won’t change prices at a visitor’s request or take on unrelated tasks.
Three steps to your first reply
Copy the script
Add it before the closing body tag on your website pages.
Build your knowledge base
Enter your website address or upload documents, and the bot will learn from them.
Customize the look
Choose a theme and colors in your dashboard; changes appear instantly.
