This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle

What I Built

I built SharNova, a secure and simple web application that allows users to share notes and files without creating an account.

SharNova generates a unique six-digit access code for every shared item. Users can protect their content with a password and set an expiration time, after which the data is automatically deleted.

The application helps students, developers, freelancers, and teams share information quickly and conveniently.

Target users: Students, developers, freelancers, and small businesses.

Potential business model: Offer a free basic version and explore premium features such as larger file uploads, extended expiration periods, and additional security options.

Open-Source AI: SharNova currently focuses on secure, temporary file sharing. No open-weight AI model has been integrated into the application yet.

Why Does Open Innovation Matter?

Open innovation helps developers build better solutions by learning from existing projects, sharing knowledge, and collaborating with the open-source community.

For SharNova, open-source technologies provide flexibility and opportunities for customization and community contributions. Integrating open-weight AI models could also enable new features while providing greater control over deployment and data handling.
