I found this compilation of free artificial intelligence websites and thought it was very useful to share. Basically, all these tools have changed the way I work, study, and create content. It used to be too expensive to access quality AI, but now everything is there for free.

I’ll start with ChatGPT, which continues to be the most versatile. The free version now uses GPT-5 models with a message limit, but once you hit the limit you use smaller, faster versions. You can generate basic images, write texts, code—everything without paying anything. If you want more, Plus costs around 20 dollars and improves performance a lot.

Google Gemini is interesting because it integrates directly with Google Drive, Gmail, and the like. The advantage is that it brings updated answers from the web in real time, which helps a lot with research. It’s also free in the basic version, with a paid option inside Google One.

DeepSeek is fast and free on the official site. People are using it a lot for analysis, math, and long-term studying. You don’t need to pay anything to use it.

For those working with video, Lumen5 automatically converts text into video. It has a limit in the free version, but you can still create basic stuff. Descript edits audio and video by text, which is very practical for podcasts. SciSpace is excellent for studying—it interprets scientific articles and explains everything.

There’s more: ChatPDF to chat with documents, Esta Pessoa Não Existe which generates realistic faces, Midjourney for images (this one is now paid), and NightCafe for digital art. Midjourney no longer has a free plan; it starts at 10 dollars.

The cool thing is that by combining ChatGPT, Gemini, and DeepSeek, you cover almost everything in text. For images, ChatGPT and NightCafe work well. For video and productivity, Lumen5, Descript, and SciSpace complete the set. Basically, with these free AIs available now, anyone can create more and better without spending anything. It really changed the game.
