At Optimanova, we’ve seen firsthand how AI has become an essential part of digital marketing, enhancing automation, personalization, and data-driven strategies.

The introduction of ChatGPT by OpenAI changed the game for content creation and customer engagement, making AI-powered interactions more natural and scalable. Shortly after, Google’s Gemini emerged as a competitor, integrating seamlessly with Google’s search and advertising platforms to refine SEO and paid media strategies. And more recently, Deepseek AI has gained global attention, offering advanced multilingual capabilities and powerful data analytics, making it an attractive tool for businesses targeting international markets.

Here in Optimanova, we are currently using AI for internal processes, predictive analytics, AI-powered content recommendations (including this blog post), and real-time customer insights—helping businesses refine their strategies and improve engagement. We’ve used all of them (and more) and can provide a comparison to assist you in choosing the right AI for your business.

Comparing ChatGPT, Gemini, and Deepseek

What is ChatGPT? 

ChatGPT, developed by OpenAI, is a generative AI model that excels in content creation, conversational marketing, and automation. Launched in late 2022, ChatGPT quickly became a staple for marketers due to its ability to generate high-quality blog posts, ad copies, and chatbot scripts within seconds. Its natural language processing (NLP) capabilities allow it to understand, respond to, and predict user queries, making it a valuable tool for improving customer experience, lead generation, and content strategy.

We have also used ChatGPT to create unique GPTs tailored to our needs and it has helped us to automate many internal processes like performance checks or brief creation.

 Chat GPT Strengths:

  • Content Generation: AI-driven blog posts, ad copies, and product descriptions.
  • Customer Interaction: Chatbots that provide 24/7 automated responses.
  • Data Insights: AI-powered analysis of audience behavior and sentiment.
  • Multilingual Capabilities: Ability to generate text in multiple languages, aiding international marketing efforts.

Cons of ChatGPT:

While ChatGPT is a powerful tool, it does come with limitations:

  • Lack of Real-Time Accuracy: It does not have real-time access to current events or live data unless integrated with external tools.
  • Fact-Checking Required: It can generate plausible but sometimes incorrect information, requiring human oversight.
  • Limited Customization: While it can be fine-tuned, its responses are based on generalized training data, which may not always align with brand-specific tone or voice.
  • Potential Bias: AI models can inadvertently reflect biases from their training data, requiring careful review when used for sensitive topics.

What is Gemini?

Developed by Google, Gemini is an advanced AI model designed to compete with ChatGPT, offering a strong emphasis on SEO optimization, search integration, and contextual understanding. As part of Google’s AI ecosystem, Gemini is deeply integrated into Google Search (Including AI Overviews), Ads, and other marketing tools, making it a powerful asset for digital marketers who rely on search visibility and advertising automation.

As part of the Google Workspace, here at Optimanova we have used Gemini to streamline our workflow with features like Email summaries or Meetings notetaking.

Gemini Strengths:

  • SEO & Search Integration: Enhances Google Search results with AI-powered suggestions and content optimizations.
  • Automated Ad Campaigns: Improves PPC targeting and bidding automation, ensuring more efficient ad placements.
  • Contextual Understanding: Better adaptation to user intent and search behavior, leading to higher relevance in marketing efforts.
  • Data-Driven Insights: Provides real-time keyword trends and audience behavior analytics to refine marketing strategies.

Cons of Gemini

While Gemini is a powerful marketing AI, it does have some limitations:

  • Limited Creativity: While effective for SEO and ads, it may lack the creative depth found in generative AI models like ChatGPT.
  • Google-Centric Bias: Since it relies heavily on Google’s ecosystem, its recommendations may prioritize Google’s platforms over alternative marketing solutions.
  • Requires Paid Integrations: Many of its most advanced features are tied to paid Google Ads and Search products, limiting accessibility for small businesses.
  • Less Conversational Depth: While strong in structured data, it may not be as effective as ChatGPT for conversational AI or freeform content creation.

What is Deepseek? 

Deepseek AI is a rising star in the AI industry, gaining recognition for its powerful multilingual processing capabilities and cutting-edge data analytics. Its rapid adoption in China and subsequent global reach highlight its potential to disrupt the AI market, particularly in areas requiring advanced translation, international marketing, and cross-market insights.

Deepseek is the newest AI tool we have incorporated in our tool belt so we are still experimenting with it, but we have found it useful when doing international research in certain markets that might be new to us.

DeepSeek Strengths:

  • Multilingual AI: Superior language processing for international marketing and global content strategies.
  • Data-Driven Insights: Advanced analytics for market trends, customer segmentation, and predictive modeling.
  • Scalability: Adaptable across multiple industries and business sizes, from small startups to global enterprises.
  • Cross-Cultural Marketing: Helps brands navigate language barriers and localize content effectively.

Cons of Deepseek

Despite its strengths, Deepseek AI also comes with certain limitations:

  • Limited English Optimization: While it excels in multilingual processing, its performance in English-based content may not always match ChatGPT or Gemini.
  • Niche Use Cases: It is more beneficial for businesses targeting international markets rather than those solely operating in English-speaking regions.
  • Data Privacy Considerations: As with any AI that processes large-scale data, privacy and compliance regulations need careful monitoring.
  • Fewer Customization Options: Compared to ChatGPT, Deepseek offers fewer brand-specific fine-tuning capabilities.

Which AI Tool is Best? 

Each of these AI tools can be used in similar scenarios, but each of them excels in different areas, and the right choice depends on your specific needs:
