Luzia

Luzia costs nothing to download or use, and you can reach it on WhatsApp, Android or iPhone. It is an AI assistant and chatbot that handles everyday questions and tasks, with extra uses as a homework helper, a math solver and an image generator.

Conversations are described as confidential, and the assistant runs on advanced AI models.

A small perk: Luzia has a rewards system called bestie points, which gives regular users something back for sticking around.

The catch is WhatsApp access, which is limited to certain countries, so check that it works where you live before you count on it.

The cookie policy also points to data collection by third-party cookies, so if privacy matters to you, read it before you start.

For students and casual users who want one free assistant in a chat app they already use, Luzia covers a lot of ground.
