What are AI chat tools and what are they used for?
From simple text chat to voice conversation, document analysis and expert personas — everything you need to know about AI chat tools.
AI chat tools are applications that use advanced language models to enable natural conversation between humans and machines. With the emergence of models like ChatGPT, Claude and Gemini, these tools have become everyday instruments for millions — from answering specialized questions and analyzing documents to professional consulting and content creation.
The key difference between AI chat tools and search engines is that instead of listing links, they answer directly, understand complex questions and maintain conversation context throughout a dialogue. This makes them far more suitable for multi-step tasks, deep analysis and personalized consultation.
Text Chat with Multiple Models
ChatGPT excels at creativity and coding, Claude is stronger at analyzing long documents, Gemini has access to up-to-date Google information and DeepSeek is an economical open-source option. A good platform lets you switch between models quickly to get the best result from each one.
Realtime Voice Conversation
Instead of typing, speak directly and receive voice responses — without noticeable delay. Ideal for language practice, hands-free situations or anyone who prefers speaking. The key difference from speech-to-text: AI responses are also delivered as audio, creating a true two-way conversation.
Chatting with PDF and Word Files
Upload a PDF, Word or CSV file and ask questions about its content, get summaries or extract specific information. For lawyers, researchers, managers and anyone dealing with large volumes of documents — get answers in minutes instead of hours of reading.
Website Content Analysis
Enter any web page URL and AI analyzes its content. Perfect for competitor research, news summarization, pre-meeting company research or reviewing products on e-commerce sites — without manually reading through long pages.
Specialized AI Expert Personas
Instead of a generic assistant, interact with a specific character with unique expertise and conversational style. A financial advisor responds with deep financial knowledge, a psychologist speaks supportively, a personal trainer gives individualized programs. Conversations become more targeted and responses more specialized.
Building Custom Chatbots
Create an intelligent assistant with your own business knowledge base and embed it on your website. It answers customer questions, introduces products and stays available 24/7 — without a permanent support team. Fully customize its knowledge, tone and personality.
Choosing the right tool depends on the task. For everyday general work, pro chat is sufficient. For large document volumes, file chat is the better choice. For specialized consultation, expert personas are most helpful. For web content analysis, web chat is the top option. The key point: there's no need to choose between these tools — DeepFA offers all of them in one integrated platform.
