What are AI Chatbots?

You can think of Chatbots as a kind of digital teammate that understands the natural language of humans and answers in real time. The earlier Chatbots used to follow rigid scripts. If you used Chatbots in 2015-16, you must have known how irritating FAQ bots were.

Today’s Chatbots use large language models (LLMs) and GPT-4 or Gemini’s most advanced and popular reasoning engine that smartly handles nuanced conversations and generates content as per the input.

These models can also process images and voice. And the models have evolved from simple rule-based helpers that work like adaptive assistants and can easily handle complex queries, be it scheduling appointments in healthcare or upselling in e-commerce.

How Do AI Chatbots Work?

When I used Chatbots for the first time, I also thought a lot that how does this AI Chatbot understand my words, let's try to understand it from a technical perspective, actually Bots are understood as structured units, that's why Chatbots use NLP (Natural Language Processing) in which human language is settled in a structured unit, from that AI and the final result is given in Natural Language.

• Understanding your input: When you give your input to the Chatbot, the Chatbots use NLP algorithms to break it down into text and voice, and then it is converted into machine-readable tokens.
• Reasoning with LLMs: These models are trained on vast datasets to predict contextually relevant responses, and many models have started using real-time data as well.
• Real-time data processing: As we know, some LLMS models like ChatGPT or Grok can fetch real-time information and give you output accordingly.
• Continuous learning: The biggest advantage of LLMs is their continuous learning, which enhances their previous replies with each interaction, and their accuracy improves with time, and it starts giving personalisation results.

Key Features to Look for in an AI Chatbot

Most people make a lot of mistakes while choosing an AI Chatbot, which affects their overall productivity and ROI. Let's know some important factors which you should consider while choosing your Chatbot.

• Multimodal capabilities: Always try to choose an AI model that supports Multimodality, so that it can handle text, voice, images, or even video.

OpenAI's GPT-4o has the capability to it can easily handle video input.

• Integration support: AI Chatbots must have integration support features so that they are compatible with different Google Workspace or Microsoft ecosystems, like 365, and HubSpot.
• Security & data privacy: The privacy of Chatbots is a very important factor that you must consider, and always use AI Chatbots that support international standards like GDPR and robust encryption so that your sensitive information remains safe and encrypted.
