Question: I'm looking for a conversational interface that supports follow-up questions with AI responses.

If you want a conversational interface that lets you ask follow-up questions and get an AI response, RhetorAI is a great choice. The service, which relies on ChatGPT, lets you create your own chatbots to communicate with customers and get useful information. It can ask follow-up questions automatically to drill deeper, and it can provide transcripts, work in multiple languages, have a variable conversation length and be embedded in a website. It's good for businesses that want to get feedback in real time to make decisions.

Another interesting project is Poe, which provides a conversational interface to interact with a variety of AI models, including GPT-4 and GPT-3.5-Turbo. Poe is geared for quick question-and-answer follow-up dialog, giving you a single interface to interact with a variety of AI engines. That means you can easily try out different AI tools and services like chat and creative tools like DALLE 3.

For a more playful interface, xAI has Grok, a conversational AI interface that can answer a broad range of questions with a bit of humor drawn from the Hitchhiker's Guide to the Galaxy. Grok is designed to give you useful answers and ask follow-up questions based on up-to-the-minute information. It can accept multimodal input and understand long context, so it can be a good research assistant that can process data and generate new ideas.

Last, ChatGPT is a simple AI-powered tool for answering questions and sparking ideas. The free tool is good for writing, learning and brainstorming, and it's a low-friction way to get help when you need it. It's good for individuals and companies that want to get a leg up without having to pay for it upfront.
