HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

Astra AI is building a dedicated one-on-one tutoring platform around large language models for school and university learners, turning an AI chatbot into a structured study companion across math, physics, chemistry and other subjects. Students interact through a conversational interface but always within the context of homework help, step-by-step explanations and targeted exam preparation, accessible on web, iOS and Android devices for everyday study.
At the core of Astra AI are two pillars: subject tutors and Exam Prep. Learners can talk to an AI tutor for math, physics, chemistry and more, or generate a custom exam preparation plan by selecting a subject, setting the exam date and mastery goal, and uploading their own materials such as class notes, past tests or slides. The system uses this corpus plus the student’s declared school level to tailor the difficulty, sequence of problems and explanations to their curriculum and context.
In this interview, filmed at Web Summit Lisbon 2025, the team walks through the interface: a chat-centric workspace with a math keyboard, calculator, drawing area and camera input so you can snap a photo of a problem. Students can switch between Solver Mode, which focuses on efficient step-by-step solutions, and Socratic Mode, which behaves more like a human tutor, asking guiding questions and probing understanding rather than just emitting final answers in a vacuum.
Astra AI follows a freemium model: new users can register and use the tutor with a daily question limit and then upgrade to a subscription (around €24 per month or €120 per year) for unrestricted usage. According to the team, the platform has attracted more than 600,000 learners, starting from Slovenia and now growing quickly in German-speaking markets, with specialized offerings such as Astra IB Math for International Baccalaureate exam preparation across standard and higher level tracks.
Compared with general-purpose chatbots like ChatGPT, Astra AI positions itself as an education-first layer on top of modern language models, optimizing for pedagogy rather than open-ended conversation. The discussion touches on challenges such as keeping students motivated, using light gamification, and designing UX that encourages regular returns to the app, whether on a phone, laptop or even e-paper style tablets like Daylight Computer, pointing toward a future where having a personal AI tutor is as normal as using a calculator in study.
I filmed 70+ videos at Web Summit Lisbon 2025 I will publish them over the coming days/weeks into my Web Summit playlist: https://www.youtube.com/playlist?list=PL7xXqJFxvYvhGWhynTmvAvDvohtO3qjZm I publish one video (from this and from other events I recently filmed at) every 6 hours at 5AM/11AM/5PM/11PM CET/EST. Be a member on my https://youtube.com/charbax/join to get early access to all my videos (after they’ve been queued up for publishing)
