neuroflash
neuroflash is the leading AI software for content generation for marketing teams in the DACH region, used by over 1 million users. With neuroflash, you can automatically create on-brand marketing texts and images. The AI will use your brand's voice to communicate more succinctly and relevantly for target groups. In addition, neuroflash has its own tool for predicting the performance of texts (what consumers think and feel) in order to simplify the life of all marketers.
You determine how your texts sound. Ensure that your content is optimized for your brand by creating a brand voice and filling it with knowledge about your brand or your company. You can also upload information, e.g., about a specific product or general background knowledge. The AI applies all this when generating the texts - for on-brand content, anytime and anywhere!
Your No.1 alternative to ChatGPT. In ChatFlash, you can create long texts and use templates to create content. In addition, use a brand voice, e.g., your corporate brand and fill it with brand values. As a result, ChatFlash responds in the voice of the corporate brand and can personalize the content even more easily. Once the associated browser extension is downloaded, ChatFlash can even be used on any website.
neuroflash offers over 100 content templates, which can write texts in 21 different languages in a matter of seconds. Among other things, the tool offers workflows for SEO blog articles or entire social media posts. You can also find templates for website content or creative texts. Afterward, the texts can be revised directly in the app and optimized for grammar and spelling using LanguageTool.
Invite your team members and share templates or entire texts to use neuroflash as a team.
In addition to creating texts, you can also create AI images. After defining the subject and style, the image is created and can be downloaded afterward. Associations to topics can also be queried with ResearchFlash and the PerformanceFlash tool predicts the performance of the texts. This is a real superpower for marketers as they are able to see how their content will perform before releasing the content. The tool also provides tips on how to optimize your content for your target group or your brand.
