Luzia

Luzia is a free AI assistant for chat, writing, translation, math, code, transcription and image generation, available as a mobile app and on WhatsApp. A paid Luzia+ tier removes ads and adds a reasoning mode, and a beta agent mode handles tasks.

Luzia is a general-purpose AI assistant aimed at everyday users rather than specialists. It answers questions, writes and translates text, helps with mathematics and code, explains concepts, transcribes audio, and generates images from a description. The homepage frames it as a friendly, human-feeling companion and reports more than 85 million users worldwide, with a claim of ranking as the top app in several countries. In practice, Luzia works as a chat interface with a small set of tools next to the prompt box: uploading an image, creating an image, uploading a PDF and running a web search. It can be used through a mobile app or through WhatsApp, which lowers the barrier for people who would rather talk to an assistant inside a messaging thread than install yet another tool. A web chat entry point also exists. Users can additionally create custom AI characters, described on the site as personal AI friends, which pushes the product toward the companion side of the category. A newer beta feature called LuziClaw puts Luzia into agent mode. Instead of only explaining how to do something, it is shown handling reminders, drafting a difficult message such as a landlord complaint and asking before sending it, comparing prices while shopping, and organizing email and calendar items. The beta is limited to select countries. The core service is free. A paid tier, Luzia+, adds longer chats and images, removes ads, unlocks an advanced reasoning mode, allows several AI friends, raises image quality and includes extra premium tools. Compared with other general chat assistants, Luzia leans on mass-market reach, messaging-app access and a companion personality instead of enterprise integrations or deep customization. It suits casual users, students and people who want one assistant for writing, translation, homework help and light life admin, and less so teams needing documented workflows or API access.
