Beyond Generative AI: 8 AI Technologies for Every Stage of the Customer Journey

When I talk to marketers about AI, the conversation almost always immediately shifts to ChatGPT or other generative AI tools. That’s understandable, since these tools have become extremely accessible. But did you know there are many more AI technologies that can enhance your marketing activities?

The real power of AI in marketing lies in the smart application of various AI technologies throughout the entire customer journey. Because what customers really want is not to talk to AI—but to experience a seamless process from awareness to retention.

In this article, I’ll walk you through 8 different AI technologies and show how they can help you better support your customers.

The 8 AI technologies every marketer should know

Based on extensive research, we’ve identified eight key categories of AI technologies that are especially relevant for marketing. Let’s take a look at each:

1. Predictive analytics & machine learning

What is it? Predictive analytics uses machine learning to analyze historical data, identify patterns, and forecast customer behavior and marketing outcomes.

What can you do with it?

Advantages:

  • Make data-driven decisions
  • Proactively address customer needs
  • Optimize your marketing budget
  • Achieve better results with more focused efforts

Disadvantages:

  • Requires solid historical data
  • Performs poorly in new situations
  • Can inherit bias from training data

Real-world example: A B2B company uses predictive models for lead scoring, allowing sales to focus on the most promising prospects and increasing conversion rates by 20–30%. Subscription services use these models to identify likely churners and proactively re-engage them.

2. Natural language processing & generation (NLP/G)

What is it? NLP enables computers to understand, process, and generate human language using deep learning models.

What can you do with it?

Advantages:

  • Automate textual communication
  • Extract insights from unstructured text data
  • Enhance customer conversations with chatbots
  • Create content at scale

Disadvantages:

  • Can generate inaccurate information
  • Lacks deep contextual understanding
  • Requires human oversight
  • Struggles with nuanced language

Real-world example: A hotel chain uses NLP to analyze online reviews and social media mentions and quickly responds to dissatisfied customers, increasing positive feedback by 15%. Companies also deploy chatbots to provide real-time assistance, reducing support costs and improving 24/7 availability.

3. Computer vision

What is it? Computer vision enables computers to understand and analyze images and videos, such as recognizing objects, people, and activities.

What can you do with it?

Advantages:

  • Automatically find brands and products in social media
  • Search using images instead of text
  • Extract data from visual content
  • Enable new interactive AR experiences

Disadvantages:

  • Requires significant computing power
  • Raises privacy concerns with facial recognition
  • Needs many labeled examples
  • Performs less well in unusual visual situations

Real-world example: A sports brand uses computer vision to recognize its products in Instagram photos. This gives insight into real-life customer use and helps repurpose user-generated content in marketing. Companies also use CV to automatically detect logos in UGC to measure brand visibility across platforms.

4. Speech processing & voice technologies

What is it? Speech technologies convert spoken language into text (speech recognition) and generate spoken responses from text (speech synthesis).

What can you do with it?

Advantages:

  • Enable hands-free interactions
  • Improve accessibility
  • Open new voice-based marketing channels
  • Create natural user interfaces

Disadvantages:

  • Less accurate with accents or background noise
  • Privacy concerns with always-listening devices
  • Technically challenging to implement

Real-world example: A supermarket chain offers voice-driven shopping lists and optimizes its website for voice commands. This improves accessibility and drives traffic via voice search. Brands use voice interfaces to answer product questions, reducing friction and increasing engagement among voice-preferring users.

5. Generative AI

What is it? Generative AI includes systems that create new content (text, images, video, audio) based on patterns learned from training data.

What can you do with it?

Advantages:

  • Create content quickly and at scale
  • Scale personalization
  • Develop innovative creative concepts
  • Produce marketing materials cost-effectively

Disadvantages:

  • Inconsistent output quality
  • Can generate inaccurate information
  • Copyright concerns
  • Requires human oversight

Real-world example: Marketing teams use generative AI to create content plans, write social posts, newsletters, and product descriptions. This reduces production time and increases output. Brands use tools like Midjourney and Runway to create campaign visuals, product renders, and social content, lowering design costs and enabling faster iteration.

6. Recommendation systems

What is it? Recommendation systems suggest products, content, or actions based on user behavior, preferences, and similarities to other users.

What can you do with it?

Advantages:

  • Increase average order value
  • Improve user experience through relevance
  • Extend session duration on site or platform
  • Boost conversion rates

Disadvantages:

  • Struggles with new users/products (cold start)
  • Can create filter bubbles that limit discovery
  • Requires sufficient interaction data
  • Privacy concerns

Real-world example: E-commerce platforms use recommendation engines to suggest relevant products based on browsing history and similar customer behavior, increasing average order value by 10–30%. Media companies use AI to recommend content, increasing engagement and reducing churn by providing more personal value.

7. Optimization algorithms & reinforcement learning

What is it? These technologies enhance marketing decisions by experimenting and learning from outcomes. Reinforcement learning teaches systems the best actions by trial and error.

What can you do with it?

Advantages:

  • Continuously improve marketing strategies
  • Optimize marketing budgets
  • Make data-driven decisions on pricing and promotions
  • Adapt to market changes automatically

Disadvantages:

  • Requires clear success metrics
  • May focus too much on short-term results
  • Needs large amounts of data
  • Can lead to unexpected outcomes

Real-world example: Companies use reinforcement learning to continuously improve pricing strategies based on conversions, competition, and customer value—maximizing revenue while staying competitive. Marketers apply optimization algorithms to test multiple content variants at once, automatically shifting traffic to the best-performing versions to increase conversions and engagement.

8. Advanced data analysis & unsupervised learning

What is it? These techniques analyze large, complex datasets to extract insights, identify patterns, and detect anomalies—without predefined labels.

What can you do with it?

Advantages:

  • Extract deeper insights from complex data
  • Identify unexpected patterns and correlations
  • Better understand which channels truly contribute
  • Proactively detect problems and opportunities

Disadvantages:

  • Challenges with data quality and integration
  • Often hard to interpret
  • Risk of identifying false correlations
  • Can be difficult to implement

Real-world example: AI algorithms continuously analyze data from various touchpoints (website interactions, social media engagement, support tickets) to identify friction in the customer journey. Companies use AI to better understand which channels drive conversions, improving budget allocation and ROI by 15–25%.

The power of combination: how AI technologies reinforce each other

The real value of AI in marketing emerges when these technologies work together. Such combinations create powerful improvement loops that are worth more than the sum of their parts:

Data–insight–action loops

AI technologies create continuous improvement cycles where:

Example: A retailer’s analytics system identifies customer groups with similar browsing behavior, predictive models forecast their purchase likelihood, optimization algorithms create personalized offers, and analytics measures effectiveness—each component improving over time.

Perceive–understand–generate workflows

Technologies that perceive, understand, and generate content work hand in hand:

Example: A cosmetics brand uses computer vision to analyze social posts featuring their products, NLP to understand context and sentiment, generative AI to craft personalized responses, and recommendation systems to suggest matching products.
