Luzia

Luzia is a free AI assistant app that answers questions, helps with homework and everyday tasks, transcribes audio and creates images, built for Spanish and Portuguese speakers who want AI that feels approachable. It grew famous as an assistant you could message inside WhatsApp, which made it many people's first experience with generative AI. Its focus on warmth, simple language and local markets is what sets it apart from the big lab chat apps.

What is Luzia used for?

People use Luzia for quick everyday help in a chat format. You type, speak or upload something, and Luzia responds in a conversational way.

• Getting help with math problems, school writing and explanations of hard concepts
• Translating text and understanding messages in another language
• Taking a photo of something and asking about it, or uploading a PDF to get answers
• Transcribing audio clips into text
• Generating images from a description
• Creating a custom AI character to chat with, such as a personal AI best friend

Who Luzia is best for

Luzia fits students, families and everyday users in Latin America, Spain and Brazil who want a free assistant that speaks their language naturally. It is a good first AI app for people who find general-purpose chatbots intimidating. Professionals who need deep file analysis, coding environments or team features will find ChatGPT, Gemini or Claude more capable, and people looking for an assistant inside WhatsApp now need to use Luzia's own apps instead.

Luzia pricing

As of October 2026 the Luzia website describes the core assistant as free on iOS, Android, web and desktop. An optional Luzia+ subscription adds an enhanced experience: about twice the images and longer chats, a smarter AI with an advanced reasoning mode, higher quality image generation, and exclusive premium tools. Luzia does not publish Luzia+ prices on its website; the price is shown in the app and app stores and can vary by country and billing period.

Limitations to keep in mind

• Luzia no longer runs inside WhatsApp after Meta's 2026 policy change for general chatbots, so it requires its own app
• Luzia+ prices are not public on the website, which makes comparisons harder
• As with any AI assistant, answers for homework or health questions should be checked
• The product is tuned for Spanish and Portuguese speakers, with less focus on other markets

Luzia vs alternatives

ChatGPT is the stronger choice for complex reasoning, long documents, coding and a wide range of tools, and also offers a free tier. Meta AI is free inside WhatsApp, Instagram and Messenger, so it is the easiest pick for people who want AI in their chats without another app. Google Gemini is a good fit for Android users who want deep integration with Google services. Microsoft Copilot suits Windows and Office users. Luzia wins for people who want a simple, friendly, free assistant in Spanish or Portuguese with custom characters and audio transcription.

Tips for getting started with Luzia

Install the mobile app if you used Luzia in WhatsApp before, since that is where it now lives. Try sending a photo of a homework problem or document, which is often faster than typing. Create a custom character only if you want a companion, and keep factual questions in the main assistant chat.
