One top pick is ChatFast. The app lets companies create their own AI chatbots based on their own data, including text files, PDFs and website links. It also comes with features like 24/7 customer support in more than 95 languages, a smart forms builder and personalized recommendations. ChatFast also offers a flexible and scalable foundation for automating work and customer service, with a variety of pricing plans including a free tier.
Another strong contender is Whismer, a no-code AI chatbot creation platform. Whismer can handle documents like PDF, DOC, CSV and TXT, and you can add web links and notes to train the AI. It's good for building custom AI tools for your own domain, with features like one-click project sharing and quick generation of an AI knowledge base.
