Geekworkers, a digital agency in Lausanne, usesArtificial Intelligence (ChatGPT, Bard, DALL-E 2, MidJourney, Perplexity) to accelerate and enrich the variation generation phase for your A/B testsWe use AI to quickly generate alternative titles, taglines, descriptions, images, or banners, which we then refine to ensure their relevance and quality, allowing you to test more hypotheses and optimize your SME in Switzerland faster.
