The Free AI Tool To Replace Them All At Work

The only AI that works with your work, while other AI assistants do basic generative AI with a skin on top of ChatGPT.

  • AI Agents: Offload the busywork with custom AI agents that act, respond, and execute for your team.
  • AI Meetings: Every meeting becomes notes, tasks, agendas, and follow-ups, automatically.
  • AI Creator: Turn ideas into visuals, writing, and tasks with zero prompt engineering or manual work.

Brain's comprehensive capabilities replace the need for dozens of other AI tools.

⏪ OpenAI brings back GPT-4o after user backlash LINK
  • Following the release of GPT-5, many users on Reddit expressed frustration, describing the new model as colder and more sterile compared to the previous, more personal-feeling GPT-4o model.
  • Responding to demands during a Reddit AMA, Sam Altman announced OpenAI will bring back GPT-4o for ChatGPT Plus subscribers and monitor its usage to determine how long it is supported.
  • Altman also explained a faulty "autoswitcher" made GPT-5 seem less intelligent and promised the chatbot will now clarify which version is responding to prompts and double Plus user rate limits.
⚖️ AI firms face largest ever copyright class action LINK
  • AI industry groups are trying to stop the largest copyright class action ever certified, which could involve seven million claimants suing generative AI company Anthropic over its training data.
  • Anthropic petitioned to appeal the decision, claiming the judge rushed the judgment without a "rigorous analysis," creating a risk of hundreds of billions of dollars in potential damages.
  • Tech associations warn that this immense financial risk might force a settlement, setting a precedent that could harm other generative AI companies facing similar copyright lawsuits.
🤖 China opens the world's first humanoid robot mall LINK
  • China has opened its first full-scale Robot Mall in Beijing, a four-story shopping center showcasing over 100 different models from more than 40 brands, including Ubtech and Unitree Robotics.
  • The store operates on a "4S" model similar to a car dealership, which combines sales, service, spare parts, and customer feedback surveys all together in one single location.
  • Beyond shopping, visitors can eat at a restaurant with robot chefs, watch robots play soccer, or meet animatronic versions of historical figures like Isaac Newton and Emperor Qin Shi Huang.
🧑‍🚀 NASA and Google build an AI for astronaut health LINK
  • NASA and Google are creating an AI medical assistant called Crew Medical Officer Digital Assistant to help astronauts diagnose and treat health issues when they cannot contact doctors on Earth.
  • The multi-modal tool runs on Google’s Vertex AI platform using text, speech, and images, while NASA owns the source code and helps to fine-tune the AI models for space missions.
  • In early tests for ankle, flank, and ear pain, physicians judged the AI's diagnostic accuracy to be up to 88% correct, with plans to add data from medical devices.
🧬 Patient produces own insulin after gene-edited cell transplant LINK
  • A man with type 1 diabetes received transplanted islet cells genetically modified with CRISPR, allowing his body to produce some insulin without needing the usual immunosuppressant anti-rejection drugs after the procedure.
  • Scientists used CRISPR to remove HLA-I and HLA-II antigens from the donated beta cells and also engineered them to produce more CD47 protein, which helps prevent an immune system attack.
  • Although the patient still needs external insulin because he only received 7% of a full dose, the fully edited cells survived and were manufacturing insulin three months after the transplant.
🛑 RIP Microsoft Lens, a simple little app that’s getting replaced by AI LINK
  • Microsoft will discontinue its popular mobile document scanner, Microsoft Lens, directing people instead to the company's Copilot AI chat application for any future scanning after September 2025.
  • The replacement Copilot app lacks crucial Lens features like saving scans to OneNote, Word, or PowerPoint, and it also removes important accessibility tools such as Immersive Reader integration.
  • Unlike many modern apps, Lens was a simple, free tool that performed its job well without pushing subscriptions, remaining popular with over 92 million downloads recorded since January 2017.
