Features
What NexJu AI does for your website.
The assistant answers questions from your knowledge, takes requests and says openly what it does not know. Eleven features and their limits.
Answers from your knowledge
NexJu AI only answers from what you have approved: your website, your documents and your additions. If something is missing, the assistant says so and offers to take a request.
- 30, 60 or 120 pages depending on the plan
- PDF as knowledge from Plus
- Multiple locations from Profi
- No answer without approval
Knowledge that stays up to date
If you wish, the assistant reads your website again every week and shows you in the account what would change. It never automatically overwrites content you have entered manually.
- As a suggestion or automatically
- Old and new side by side
- Notices with an expiry date for holidays and promotions
Answers that help visitors take the next step
The assistant knows from which page someone is writing. Below its answer are the matching page of your website, a card for the service or the number for urgent cases.
- Link to the source
- Cards with image and price
- Buttons: call, directions, email, WhatsApp
- Files to download
Your rules
You decide how the assistant sounds, what it mentions in suitable answers and what it does not talk about.
- Short to detailed
- Casual to formal
- Always mention
- Never address
Requests that reach you
For a quote, a callback or an appointment, the assistant asks what the visitor needs, their name and their contact details. The visitor checks the summary and submits the request themselves.
- Email to you
- Inbox in the account
- Extra questions per industry
- Draft reply
- Deletion period 30 to 365 days
- Up to three photos from Plus
- Additional recipients by keyword from Profi
- Webhook, Zapier and Make from Profi
Appointments and reservations
With Plus or Profi and a cal.com account, the assistant shows available times from your calendar, and visitors book directly in the chat window. In every plan it gives the link to your booking system or your phone number.
- Booking via cal.com from Plus
- Booked only after checking and clicking
- Without a link: preferred appointment sent as a request
- It adds: not yet a confirmation
Languages
In every plan the assistant answers in German and English. From the Plus plan it answers in the language your visitor writes in.
- Your knowledge stays in German
- The assistant translates its meaning
Appearance and form of address
You choose light or dark, the accent colour, the text on the tab and whether visitors are addressed formally (“Sie”) or informally (“du”) in German. If you wish, the window sits fixed inside a page instead of at the edge.
- Large font with one button
- Greeting per page
- Addresses visitors proactively
- Avoids fixed bars
- Own logo from Plus
Without installation: link and QR code
Every assistant can have its own page. You put the link into your Google or Instagram profile, the QR code into the shop window or onto a flyer.
- QR code to download
- Legal notice and privacy policy linked
Fast and lean
Only a 4.8 kilobyte script that draws the tab loads with your page. The chat window is only added when someone opens it.
