Under the Hood
An AI chat app is the first and foremost developed app using artificial intelligence or LLM.
Before moving ahead with the blog try the AI chat app template demo
Let me explain, chat GPT came into the world 5 years ago that is 2020–2021 every AI or LLM-based company is training the models to bring AI chat apps into the real world.
We all see the real power of AI or GPT at the chat GPT launch so one can clearly understand why having an AI chat app is the first and foremost priority of every LLM-based company.
Moving ahead, the main reason I’ve brought this blog is to introduce you all to the fastest way to get your own AI chat app.
Next time your client asks for an AI chat app you can reuse the same template and deliver quickly and effortlessly in just 29USD.
Yes, 29USD sounds a quite reasonable price point to have your own AI chat app that supports multiple models like Gemini, OpenAI, Claude and Mistral.
Our chat app stores the user chats and messages along with the user authentication using Google, Github and Email/Password making the template a full-fledge personalised chat GPT app.
