NAiOS Agent: Create complete business applications from chat

Describe what you need. Connect your APIs. Get full stack apps in minutes. With over 400 AI models at your disposal.

In Spain, Netretina has launched NAiOS Agent (naios.net): the first agnostic AI agentAI AgentsSystems that execute multi-step tasks without constant supervision that turns conversations into real business applications, connected to your systems and ready for cloud production.


+400 AI models. You choose.

NAiOS Agent does not rely on a single AI provider. It is completely agnostic to the model, with access to over 400 integrated models:

  • OpenAI: GPT-4o, GPT-4 Turbo, o1, o3...
  • Anthropic: Claude Opus, Sonnet, Haiku...
  • Google: Gemini Pro, Gemini Ultra...
  • Meta: Llama 3, Llama 4...
  • Mistral: Mixtral, Mistral Large...
  • Open Source: DeepSeek, Qwen, Phi, and hundreds more

Why does it matter?

  • You choose the optimal model for each task (cost, speed, capability)
  • You are not dependent on a single provider
  • You can switch models without changing your application
  • You automatically benefit from industry advancements

Multimodal: text, image, voice, documents

NAiOS Agent does not only understand text. It is completely multimodalMultimodalModels that understand and generate text, image, audio and video:

  • Text: Describe what you need in natural language
  • Images: Upload mockups, screenshots, or diagrams and NAiOS interprets them
  • Documents: Attach PDFs, excels, or technical specs as reference
  • Voice: Dictate your requirements if you prefer to speak

The applications it generates can also be multimodal: image processing, OCR, visual content generation, audio transcription, document analysis...


How does NAiOS Agent work?

You open the chat. You describe your need. NAiOS does the rest.

Real example:

"I need an app for my salespeople to log client visits. They should be able to add notes, photos, and geolocation. It should sync with our CRM in HubSpot and generate an automatic weekly report for me."

NAiOS Agent generates:

  • Responsive frontend (web and mobile)
  • Backend with complete API
  • Structured database
  • Integration with HubSpot
  • Automated reporting system
  • User authentication and roles

In minutes, not weeks. And you receive a preview link to validate with your team before going into production.


API-first applications: connect everything

Every application created by NAiOS Agent is API-connectable by design. This means:

Your new apps connect to your current systems:

  • ERPs (SAP, Sage, A3, Holded, Odoo...)
  • CRMs (Salesforce, HubSpot, Zoho, Pipedrive...)
  • Databases (MySQL, PostgreSQL, MongoDB, SQL Server...)
  • Payment gateways (Stripe, Redsys, PayPal...)
  • Communications (Twilio, SendGrid, WhatsApp Business...)
  • Any REST or GraphQL API from your organization

Your new apps expose APIs for other systems:

  • Other departments can consume your data
  • Future integrations are already prepared
  • Automations with n8n, Make, Zapier...
  • Connection with BI dashboards

You are not building isolated apps. You are building pieces that fit into your ecosystem.


The complete flow: Preview → Live → Marketplace

1. Instant Preview

You describe, NAiOS generates, you receive a link. Share it, gather feedback, adjust in the same chat. No requirement documents. No endless meetings.

2. Production with one click

When the preview is validated, you activate the live environment in the cloud. Own domain, SSL, ready for real users.

3. Marketplace to monetize

Can your app serve other companies in your sector? Publish it in the NAiOS marketplace. Turn your development into a product.

From idea to published app: minutes.


Real Full Stack in the cloud

When NAiOS Agent creates an application, it generates the entire cloud-native stack:

Layer What NAiOS generates
Frontend Responsive interface, adapted for web and mobile
Backend Complete REST API with business logic
Database Optimized structure, scalable in the cloud
Authentication Users, roles, permissions, SSO
APIs Documented endpoints for integration
Integrated AI Embedded AI capabilities if you need them

It is not a prototype. It is production software deployed on European cloud infrastructure.


Technology stack 2026: Agnostic AI + Cloud + APIs

The business stack of 2026 cannot depend on a single AI provider or isolated systems. NAiOS Agent is designed for this scenario:

✅ Agnostic to the model: Switch AI providers without rewriting anything

NAiOS GIS: the map they sent you, open in a minute and in 3D

A shapefile zip, a Google Earth KMZ, a GPX or an Excel file with coordinates: until today, you needed a desktop program and a technician to open them. GIS, the new module included in all NAiOS plans, converts them into layers of a project, calculates hectares and kilometres, shows them on a map in plain language and in 3D over the real terrain, and lets the chat read them as attachments. It was born from a support ticket and was on all platforms in a day.

Digital Transformation

The agent multiplies what you already know, and also what you don't know

One person with a coding agent closed 47 commits in a day. The figure is not the important thing: what matters is that writing code has stopped being the bottleneck and that the agent amplifies, with the same good appearance, both the judgement and the gaps of the person directing it. What to ask for, what it can touch, how far it goes, how we do it and why it applies equally to agents that do not write code.
