Jarvis handles a set of conversational and informational commands out of the box — look up any topic on Wikipedia, hear today’s date and time spoken aloud, or get a friendly response when you just want to check in. Wikipedia lookups and speech recognition both require an active internet connection; casual responses work fully offline.
The date and time commands are implemented only in Jarvis2.py (the Ubuntu version). They are not available in Jarvis2_4windows.py (the Windows version).

​
Wikipedia lookups

Say “wikipedia [topic]” to get a spoken summary of any article. Jarvis strips the trigger word from your query, fetches the first two sentences of the Wikipedia article, and speaks them back.
In Jarvis2_4windows.py, command_wikipedia is called as command_wikipedia(speak, debug, query) — passing the speak function as the first argument. The function definition in commands.py declares command_wikipedia(debug, query) (two parameters). The speak import from actions is used directly inside the function body.
def command_wikipedia(debug, query):
    speak("Searching wikipedia....")
    query = query.replace("wikipedia", "")
    results = wikipedia.summary(query, sentences=2)
    if debug == "True":
        print(results)
    else:
        pass
    speak(results)
The wikipedia.summary() call uses the wikipedia Python package with sentences=2 so the response stays concise enough to speak. If the topic is ambiguous or not found, the library raises a wikipedia.exceptions.DisambiguationError or wikipedia.exceptions.PageError — Jarvis will not catch these silently in the current implementation, so try rephrasing with a more specific topic name.
Wikipedia lookups require an active internet connection. If the request fails, Jarvis will raise an unhandled exception. Make sure you are online before using this command.

​
Current date

Say “date” to hear today’s date. Jarvis formats datetime.datetime.now() using Python’s strftime mini-language and speaks the result: 
elif "date" in query:
    print_and_speak(f"{datetime.datetime.now():%A, %B %d, %Y}")
Example output: Monday, June 09, 2025 The format string %A, %B %d, %Y expands to the full weekday name, full month name, zero-padded day, and four-digit year.

​
Current time

Say “time” to hear the current time in 12-hour format: 
elif "time" in query:
    print_and_speak(f"{datetime.datetime.now():%I %M %p}")
Example output: 02 45 PM The format string %I %M %p gives the 12-hour clock hour, minutes, and the AM/PM designator — separated by spaces so the TTS engine reads each part naturally.

​
”What’s up”

Say “what’s up” to get a random casual reply. Jarvis picks one response at random from a fixed list every time: 
def command_whatsup():
    st_msgs = [
        "Just doing my thing!",
        "I am fine!",
        "Nice!",
        "I am nice and full of energy",
    ]
    speak(random.choice(st_msgs))
These responses are fully offline — no network call is made. command_whatsup() is triggered when "what's up" is detected in the recognized query.
You can customize the casual responses by editing the st_msgs list in commands.py. Add as many entries as you like — random.choice() will pick uniformly at random from the full list.
