Alternative to LLMs or alternative to AI? I'm sure in the near future many other tools will come to fruition but unfortunately the money spent by the industry will make the bubble pop before AGI can take off.

it's rule-based engine, two .c files with <2K lines of .c total. This snippet should give you a good idea what the code is like:

    if (strstr(input, "who is") || strstr(input, "what is")) 
    {
        intent_identity = true;
    }

That's like 1960-s style rules engine, except even more basic.
