Anthropic’s Opus 4.7 hackathon showcased innovative AI-driven apps in medical training, electronics repair, and education. Winners include MedKit and Wrench Board.
The winners of Anthropic’s Built with Opus 4.7 hackathon have been revealed, showcasing how builders worldwide are using Claude Code to solve real-world issues. Held virtually from April 21 to April 26, 2026, the event attracted over 20,000 applicants, of which 500 were selected to participate. The competition centered on building production-ready applications with Anthropic’s Opus 4.7—its most advanced AI model at the time.
With a $100,000 prize pool distributed across winning projects, participants tackled challenges in fields ranging from medical training to industrial maintenance. The winners, announced on May 5, 2026, highlight the growing potential of accessible AI tools to empower specialists across industries.
MedKit: First Place ($50,000 Prize)
Taking the top spot, Istanbul-based physician-turned-developer Bedirhan Keskin created MedKit, a gamified medical training tool for junior doctors. Built using Claude Managed Agents, MedKit simulates real-life patient encounters, allowing users to practice diagnosing and treating virtual patients. The program evaluates users’ decisions against clinical guidelines, providing detailed feedback akin to a board examiner.
The project has already gained traction, with three medical faculties and a pharmaceutical company in Istanbul planning pilots. Keskin emphasized the importance of using Claude as a “thought partner” rather than just a coding assistant, a strategy that allowed him to refine the tool quickly. MedKit’s source code is available on GitHub.
Wrench Board: Second Place ($30,000 Prize)
French electronics repair expert Alexis Chapellier took second place with Wrench Board, a tool designed to assist technicians in diagnosing complex electronics issues. Users input schematics, and the app leverages Opus 4.7’s ability to interpret visual data to suggest diagnostics and solutions. Chapellier credited the hackathon for demonstrating how a self-taught builder could ship a sophisticated system in under a week. His focus now is on building a community of repair professionals to enhance the app’s capabilities. Explore Wrench Board on GitHub.
Maieutic: Third Place ($10,000 Prize)
Paula Vásquez-Henríquez, a computer science educator from Chile, developed Maieutic, an interactive IDE designed to teach programming students critical thinking. The tool forces students to articulate their coding plans in plain language before writing any code and provides targeted feedback to encourage self-reflection. Post-hackathon, researchers from the University of Houston have expressed interest in collaborating on academic papers based on Maieutic.
Other Highlights
Several additional projects received recognition for innovative use of Opus 4.7:
Virtual Puppet Theater: A browser-based app by Rene Hangstrup Møller that uses spatial reasoning to create interactive puppet shows. This project received the “Most Creative Use of Opus 4.7” award. MaestrIA: Developed by Benjamin Torralbo, this app provides expert-level home repair diagnostics and connects users with skilled tradespeople. It received the “Keep Thinking” prize for its ambitious approach to digitizing trade expertise. ARIA: Idriss Benguezzou and Adam Hnaien’s factory maintenance AI system won “Best Use of Claude Managed Agents” for its ability to diagnose and prevent machine failures in industrial settings.
Why It Matters
This hackathon underscores the growing accessibility of sophisticated AI tools like Anthropic’s Claude Code. By lowering technical barriers, more individuals—ranging from educators to medical professionals—can now build solutions tailored to their fields. According to Anthropic, the Opus 4.7 platform is designed to amplify the expertise of domain specialists, not replace them, enabling rapid prototyping and deployment of real-world applications.
While the hackathon’s prize money is significant, the broader impact lies in how these tools are democratizing AI development. Projects such as MedKit and Wrench Board demonstrate the potential for AI to address niche but critical problems across industries—whether it’s training doctors, improving electronics repair, or enhancing education methods.
For builders, Anthropic’s next hackathon presents an opportunity to leverage its forthcoming Opus 4.8 model, promising even greater capabilities. Details are expected to be announced later this year.
