Generative artificial intelligence tools such as ChatGPT (text) or Midjourney (images) have democratised and are shaking up content marketing in 2025 - their adoption has exploded in recent years. This article will look at how these technologies can help small organisations in practical ways: generation of ideas for posts or blog articles, rapid creation of promotional visuals, intelligent chatbots for customer support, personalisation of the user experience, and so on. We will also look at the limits of AI (variable quality of content, need for human proof-reading, authenticity issues) to remind us that the human touch and editorial strategy remain essential. Readers will discover tips for effectively integrating AI into their marketing while avoiding the pitfalls, all illustrated with recent examples from SMEs that have tested these tools.
Introduction
In 2025, generative artificial intelligence is on everyone's lips. It has transformed the way large companies produce content, but what about SMEs? In a context where time, human resources and budget are limited, these new technologies represent a real opportunity. But like all powerful tools, their effectiveness depends on how they are used. This article offers a comprehensive and accessible overview of this trend, which is redefining the rules of digital marketing.
As a specialist digital agency, Lumineth supports SMEs in the intelligent integration of these tools into their overall strategy, taking into account their image, resources and sector of activity.
1. What is generative AI
Generative artificial intelligence refers to a family of technologies capable of automatically creating content (text, image, video, audio) from simple instructions provided by a user. It is based on deep learning models trained on huge volumes of data. Among the best-known tools are:
- ChatGPT for copywriting or customer service
- Midjourney and DALL-E for creating advertising illustrations and visuals
- Jasper or Copy.ai for automated copywriting
- Runway for video generation
Their strength? Generating consistent, customisable and often human-like results in a matter of seconds, at a much lower cost than traditional production.
Lumineth helps you select the best tools for your purpose, set them up correctly, and avoid the pitfalls associated with their clumsy use.
2. Text content generation with AI
Text generation tools such as ChatGPT, Jasper or Copy.ai allow you to quickly create blog articles, posts for social networks, newsletters or even web pages. For an SME, this means being able to publish more regularly without systematically relying on an external writer.
All you need to do is provide a well-formulated instruction - for example, "Write a 600-word article on the benefits of energy renovation for VSEs in France" - and the template generates a structured first draft. This content then needs to be proofread and adjusted to match your company's tone, editorial strategy and values.
Lumineth offers full AI-assisted copywriting support: we help you calibrate your prompts, build your editorial line, and ensure your brand voice is consistent across all your content.
3. Visual creation and brand identity
Midjourney, DALL-E or Canva with AI allow you to quickly generate marketing visuals, advertising banners, infographics or product mockups. These tools become veritable graphic assistants. But be careful about consistency: using visuals that are too generic or poorly aligned with your graphic charter can damage your image.
For SMEs without a permanent graphic designer, these tools are invaluable. Nevertheless, they are no substitute for the human eye to harmonise the whole. That's where Lumineth comes in: we validate the use of the visuals generated, help you integrate AI into your existing charter and, if necessary, create reusable templates that respect your visual identity.
4. Automating customer relations with conversational AI
AI-boosted chatbots have become far more effective than their predecessors. They can answer frequently asked questions, direct customers to the right services and even close sales. Tools such as Tidio, Botpress or ChatGPT API make it easy for SMEs to create a conversational agent available 24/7.
For a chatbot to work well, you need to design a relevant dialogue tree, train the basic responses well, and allow for transfers to the human if necessary. Lumineth supports you in designing the user experience, configuring scenarios, and integrating the chatbot into your site or CRM.
5. Marketing personalisation thanks to AI
AI makes it possible to personalise your email campaigns, product recommendations or dynamic home pages according to user profiles. For example, a customer who has visited a product page may receive different content to one who is discovering your site for the first time.
Tools such as Klaviyo, HubSpot or Mailchimp already incorporate AI to analyse behaviour and optimise conversions. Lumineth helps you activate these levers: we identify key segments, set up automation scenarios and ensure seamless RGPD compliance.
6. Limits and precautions to be taken
While AI enables considerable time savings, it also has its limitations:
- Varying quality: generated texts may lack depth, tone or contain factual errors.
- Sensitive bias or content: some models reproduce stereotypes or errors related to training data.
- Authenticity: overly automated content can alienate your audience rather than build loyalty.
This is why Lumineth advocates a hybrid approach: AI to produce, humans to validate. We implement a methodology for proofreading, quality control and reintegrating the human touch into each deliverable.
7. Preparing for the future with a sustainable AI strategy
Rather than chasing after every new fad tool, SMEs need to integrate AI into a long-term strategic approach. It's not just a matter of adopting ChatGPT or Midjourney for a one-off need, but of structuring a coherent, managed, measurable integration plan.
Managers of small businesses need to ask themselves several key questions: what objectives do they want to achieve with these tools? On which channels will AI bring the most value? How can they ensure consistency with their brand image? How can employees be trained to use these solutions effectively?
To meet these challenges, Lumineth sets up personalised audits, draws up an AI roadmap over 6 to 12 months, and offers regular monitoring. This iterative approach makes it possible to test the tools in a supervised way, measure concrete gains and gradually ramp up without burdening the existing organisation.
Our mission is not limited to the technical aspect: we also integrate the human and ethical dimension into each project. A successful AI strategy relies as much on the algorithms as on the people who use them. As a local partner, Lumineth ensures that SMEs remain in control of their message, their pace and their vision.
