Frequently Asked Questions

Here are answers to some common questions about automating customer service using AI. There's also a more extensive FAQ about ResponseBrain.

How does the AI get information about my business?

You can give the AI any information that may be relevant. The content can be in any format, the most common sources are blog posts, website FAQs and help center articles.

How long does it take to train my custom AI?

It depends on how thorough you want to be. We recommend that you just add a couple of texts from your website to get started. That takes just a few minutes and gives the AI enough context to answer basic questions. The more business data you add over time, the more powerful your AI becomes of course!

Do I need any technical knowledge to train and use the AI?

Not at all! ResponseBrain handles all of the technical stuff for you. You just copy the information about your business into some text fields and we feed it to the AI. Generating e-mail responses using the AI is just as easy - simply paste the message you want it to reply to.

What languages does the AI speak?

Since we use ChatGPT and GPT-4 in the background, your AI assistant will speak around 95 languages. It's even smart enough to reply to e-mails in different languages than the content you gave it to learn from!

How long does it take to generate a response to a message?

Your custom AI will generate a reply in just a few seconds!

How reliable are the AI's responses?

We instruct the AI not to make up any information if it can't reliably answer a question using the information it has about your business. Of course misunderstandings can always happen, so we always recommend to read through the response before you send it to a customer. We also show you which sources the AI used to generate a specific response so you can better understand how the AI comes to it's conclusions. In the case of errors, you can edit the cited training material to clarify it. That way you can avoid erros in the future.

Are you GDPR compliant?

As a German company, we follow the GDPR and respect your privacy. As you know, ChatGPT and GPT-4 are provided by OpenAI, a US company. We don't store the questions you ask the AI, but OpenAI processes them to generate the response. We recommend that you don't send personal information of your customers to the AI. You can check out our privacy policy for more detailed information on what data we store and process.

Does the AI sound natural?

The AI tries to follow the style and tone of voice from the learning material you provide it. It will also adjust depending on the style of the message it should reply to.
