Build your assistant

What it is

Your assistant answers people's questions from the knowledge you choose: documents, recordings, YouTube videos, web pages and your own Q&As. You decide who it is for, how it talks and where it lives: on your website, inside any page, as a link, or connected to your own system. It is separate from your private Nexa content.

What it's for

People get answers at any hour; you and your team answer the same question fewer times.

How to use it

1. Open AI Assistant and create a new assistant. Start with An assistant that answers from your knowledge, or pick a quick start (Assistant for my website reads your site for you; Support passes questions it can't answer to your team). A quick start only fills in a few settings; you can change everything later.
2. Give it a name. If you want each answer to show where it comes from (the file, page, minute or slide), tick Show where each answer comes from; it is off unless you turn it on.
3. In Look, set the name, welcome message, theme, colour and language. Pick one of five themes — Classic, Soft, Minimal, Dark or Bold — and your brand colour is applied on top of it. For the logo, press Upload image (PNG, JPEG or WebP; Nexa makes it a small square) or paste a link to an image. Under What visitors read you can change every line the assistant shows — the line under its name, the welcome, the question box and the Ask a question button. With Language → Automatic (follows your website) you write each line in Arabic and in English: an Arabic page shows the Arabic ones, an English page the English ones. Whichever language you pick, every answer comes in the language the visitor writes in; the setting chooses the assistant's own buttons and texts. Use Preview as to see both. You can also choose the Text color on your brand color, Your website's font, and, under The button on your site, its side, a round icon or Icon and text, and its distance from the edge. Under Branding, turn Show “Powered by Nexa” off if you want, and add Your footer line (optional) in each language — available on every plan.
4. In Behavior, choose the tone, the topics it should answer or avoid, and what it says when it doesn't know. Under When it doesn't know → Offer ways to reach your team, add any of a WhatsApp number, a Phone number (pick the country, then type the number as it is dialled there), a Team email and a Contact page: whenever the assistant has no confirmed answer, declines a topic or reaches a limit, the visitor gets a WhatsApp us, Call us, Email us or Contact page button for each one, and WhatsApp and email already carry the visitor's question. Turn on Let visitors ask by voice to add a microphone next to Send; what the visitor says is written in the box for them to check before sending. Each voice question costs a fixed number of AI credits (Voice question), and its answer is then charged like any question. Let visitors leave a phone number or email for your team (on by default): a visitor who asks to be contacted can leave one, you get a notification, and you find them under Conversations → Asked to be contacted with Mark as contacted.
5. Test it in the Live preview on the right.

Tips

• Write the welcome message as a promise: what it can help with, and that your team is there too.
• If your website is dark, choose Dark; to make the assistant stand out, choose Bold. The Live preview changes as you click.
• A video that plays on your own platform: in Knowledge, paste the page where it plays next to it. A cited minute then opens that page, signed in as the person is (YouTube, Vimeo, Wistia and Loom land on the second). Playing from Nexa stays off unless you turn it on, and then only people your site vouches for can play, and only two minutes around the moment.

Good to know

• The assistant never uses your private Nexa files, meetings or emails.
