If you are traveling, GuideGeek is essential. It is a WhatsApp bot designed for tourists.

Try texting it: "Where is the best cheap pizza in Rome?" It sends you the Google Maps location instantly.

3. MobileGPT (The Powerhouse)

This tool brings the full power of ChatGPT-4 into WhatsApp. It can generate documents, create images, and even browse the web.

Note: This usually requires a small subscription, but it is cheaper than ChatGPT Plus.

4. Cami.ai (Personal Assistant)

Cami is a friendly AI that lives in your contacts. You can send her a voice note: "Remind me to call Mom at 5 PM," and she will handle it. She can also transcribe audio messages if you hate listening to long voice notes.
