Reviews
The 7-Cal is a total beast. It looks like a standard scientific calculator, but the AI MODE with AI Chat and Chatroom functions is revolutionary. It features a full QWERTY digital keyboard and supports a massive variety of characters, making it perfect for complex notes and file management.
It’s durable, tactile, and feels like a stealthy workstation for any engineering student. Highly recommended for anyone needing an edge!
I received my 7-Cal device in just 6 business days, and it arrived in perfect condition with no damage. The camera is tiny and almost invisible to the naked eye, yet it works amazingly well. The AI throughout the calculator is very smart, making calculations quick, accurate, and effortless. I love how intuitive and easy it is to use, even for someone not very tech-savvy. The design is sleek, compact, and portable, so it fits anywhere without drawing attention. Overall, this device is great.
7 Calc is an amazing all-in-one calculator app.
What really sets it apart is the AI and ChatGPT integration, which doesn’t just give answers but actually explains them clearly. This helps a lot when you’re studying or stuck on a hard question.
The camera feature is next level — you can scan math problems directly and get instant solutions and explanations. The interface is clean, fast, and easy to use.
Overall, 7 Calc feels like a smart tutor in your pocket, not just a calculator. Definitely w
I thoroughly tested the product, including custom AI models and prompts, and I’m genuinely impressed by how smoothly and accurately everything works. I even tried building an AI-powered calculator myself and quickly realized how challenging this kind of integration is. The implementation here is outstanding — amazing work and a very well-thought-out product. Highly impressed!
