# Types

Integrations extend what your NLX AI apps can do. From how they communicate with users, to how they understand language, generate outputs, and connect to your business systems. Each type of integration unlocks different capabilities.

Select a type that fits your use case to get started or explore below for a full overview of all integration categories in NLX and what they’re used for:

### Channels

Channel integrations allow your AI application to send and receive messages through external communication platforms. These define the delivery surface for conversations: chat, voice, phone/IVR, social, mobile, and more.

Use channel integrations when you want your application to run on a specific platform.

{% hint style="info" %}
Did you know? Every NLX app includes a built-in API channel with native Voice channel (for web/mobile via Touchpoint).
{% endhint %}

Examples:

* Amazon Connect
* Alexa
* Twilio
* Slack
* Zendesk Sunshine

### NLP engines

NLP engine integrations provide the natural-language understanding needed for classic intent-based routing and structured flows. These engines classify user intents and extract values that your flows rely on.

Use NLP engines when you want deterministic language understanding and flow invocation.

{% hint style="info" %}
Did you know? NLX includes a native NLP engine with optional NLX Boost, so you can handle intent recognition, language disambiguation, and app builds without needing an external NLP (unless you prefer to bring your own).
{% endhint %}

Examples:

* Amazon Lex
* Google Dialogflow
* Custom NLP

### LLM services

LLM integrations provide generative AI capabilities for messaging, decision-making, summarization, tool use, and NLX’s Generative Journey®. These models enable flexible, contextual reasoning beyond traditional NLU.

Use LLM services when you want AI-driven logic, semantic generation, retrieval, or agentic task completion.

{% hint style="info" %}
Did you know? NLX provides a built-in generative model for flows and agentic Generative Journey, so you can optionally integrate an external LLM.
{% endhint %}

Examples:

* OpenAI
* Anthropic
* Google Vertex AI
* Cohere
* Cerebras

### Managed integrations

Managed data requests provide ready-made connectors maintained by NLX. These remove setup complexity and allow you to instantly bring external systems into your flows or agentic tools, like calendars, CRMs, productivity suites, marketing platforms, and more.

Use managed integrations when you want fast reliable access to common third-party tools without custom development.

Examples:

* HubSpot
* Google Workspace
* Airtable
* Zendesk
* Shopify
* Snowflake

### Custom integrations

Custom data requests allow you to integrate any external system by defining your own webhook or API models. You control authentication, payloads, schemas, and environments, making this ideal for internal business logic or bespoke services.

Use custom integrations when you need NLX to call your own APIs or private systems not covered by a managed provider.

Examples:

* Internal scheduling APIs
* CRM or user profile services
* Custom databases
* Proprietary workflows

### Text-to-speech (TTS)

TTS integrations synthesize spoken responses for any voice-based experience, including Voice+™, phone/IVR, and voice chat. These providers let you select language, persona, tone, and attributes.

Use TTS providers when your app needs natural-sounding or brand-aligned voice output.

{% hint style="info" %}
Did you know? NLX provides five built-in TTS providers for its native voice channel, so you can skip the time to integrate.
{% endhint %}

Examples:

* Inworld
* ElevenLabs
* Hume
* Amazon Polly
