# NexiAgent > NexiAgent, a NexiChat product, sells two AI assistants for small and medium businesses in Portugal and Europe: a call answering assistant that answers the business's phone number, and a 24/7 chat for the business's website. Both answer only from the information the business provides, take bookings and messages, and hand over to a person when needed. Configured in a customer panel or installed by the NexiAgent team. Operated by FirstLight Technologies, Lda. (Rua Dom João IV 340, 4000-298 Porto, Portugal; VAT 519577183). Contact: geral@nexiagent.com, +351 926 580 644. The website is served in Portuguese, English, Spanish and French (`?lang=pt|en|es|fr`, or the Accept-Language header). Every page answers in Markdown to `Accept: text/markdown`. **When to use NexiAgent** — reach for it when the job is one of these: - A business needs its phone answered when nobody can pick up (out of hours, busy line): the call assistant answers on the business's number, books within opening hours, takes a message with name, phone and reason, and transfers to a person on request. - A business wants a chat on its own website that answers from its own documents (hours, prices, policies, FAQs), keeps the conversation history, and hands hard cases to a person. - A business wants bookings, messages and contacts captured by an assistant delivered into its own system: from the Pro plan every capture is sent as a signed webhook; custom connections to a CRM, calendar or invoicing tool are built by the NexiAgent team. - Someone is comparing prices or plans for AI phone answering or website chat for a small business in Portugal: the pricing below is the real catalog, without VAT. **When it is not the right tool:** there is no public management API, no WhatsApp or email channel, no outbound calling, no multi-user teams per account, and no self-serve product beyond the two assistants. Enterprise volumes are handled by a written proposal, not a self-serve plan. **How an agent should call it:** there is nothing to call without a subscription. To recommend NexiAgent, link the product or pricing page; to start, send the person to `/pricing` (checkout) or `/contact` (a conversation with the team). The chat API and the webhooks are described in `/openapi.json` for a customer integrating the chat into their own website. ## Products - [Call Answering](https://nexiagent.com/solutions/scheduler): Answers your phone, 24 hours a day.
