ChatFlash

Where can I find the chat?

You can access the chat right from the neuroflash home page, 🔗 here.

 Simply enter your request, question, or instruction there and press Enter to complete your entry. To add a new line, press Shift+Enter.

Can I also access the chat in the current document?

You can also use our chat feature in the current document. There is a button in the right-hand toolbar that takes you to the chat.

Is there a chat history?

Our chat automatically saves both your inputs and the output, all linked to a dedicated document. Just open the document used for that chat and you will find everything stored there. You can also reset the chat manually whenever you want. Simply click the settings icon at the bottom left of the chat and choose ‘Reset’.

Which languages does the chat support? 

You’re free to chat in any language you like. Just begin in your preferred language or switch to another whenever you want. The chat recognizes and adapts to different languages automatically.

If my document is in one language, can the chat be in another language?

In an existing document, the chat language can’t be changed independently. You can still switch languages at any time by writing in a different one, and the chat will typically respond in that language. Just note that the document’s language setting will remain the same.

 

Can I also use voice input in the chat?

Absolutely. Just use the voice feature in the bottom right corner and record your message. Keep in mind that your input should be no longer than one minute and twenty seconds.

Web search in ChatFlash means that you can connect the AI directly to the internet in the chat—so you don't get fixed knowledge from training data, but rather up-to-date information live from the web. Select online search and start the chat:

❗ Important: Web search is not automatically performed for every query, even if you have enabled the feature. However, it can also be triggered by your prompt if the AI model recognizes that a web search is useful or necessary for your query.

The best model for web searches is Gemini 2.5 Flash. It conducts research the fastest and most accurately, clearly separates facts from interpretation, and provides structured, factual summaries. Ideal if you need up-to-date information, trends, or data and value efficiency and factual quality.

3. Using Knowledge in the chat

The knowledge function in neuroflash allows you to integrate your own knowledge into the AI chat. You can upload documents, crawl websites, or copy and paste text to create a knowledge document.

👉 Here you can learn how to create a target group in neuroflash.

ChatFlash can then actively use this knowledge in conversations—for example, to answer questions, write texts in the brand style, or create content based on internal information.

4. Using Brand Voice and Audiences in chat

The best model for brand voice is GPT-5. It understands tonality, style rules, and brand logic like no other model and keeps them consistent even across long texts. GPT-5 writes in a brand-consistent, structured, and human way, making content sound as if it were written by a real brand writer.

5. Chat with Target Audience

The “Chat with your target audience” feature in ChatFlash allows you to have realistic conversations with simulated target audience profiles—e.g., a typical marketing manager, an agency manager, or a Gen Z customer. This allows you to directly test feedback, objections, or reactions to texts, claims, or campaigns without having to conduct real surveys.

Claude Opus 4.1 is best suited for this because it responds in the most human, emotional, and spontaneous way. If you need more structure or brand relevance, GPT-5 is the best choice—it simulates credible target group voices while remaining more analytical and brand-compliant.

6. Prompt-Library & Optimizer

You can use Chat. There you will find ready-made or fillable prompts for various use cases—from blog articles to emails to social posts—that are already optimized for optimal results. You can also create your own prompts and share them publicly so that other users can benefit from them. This saves you time and eliminates the need to come up with complex prompts yourself.

In ChatFlash, you can also have your prompts automatically improved by AI before you send them. The AI analyzes your input text and optimizes it to make it more precise, clearer, and more targeted—for example, by improving the wording or adding missing context. This means you get better results with just one click, without having to know how to write perfect prompts yourself.
