As answered by people managing CubbyDrop and Diffyn.
CubbyDrop's answer
CubbyDrop is the only file sharing service that combines end-to-end encryption with peer-to-peer Live transfers via WebRTC. Files are encrypted in your browser before upload — not even CubbyDrop can access them. It also offers encrypted text/pastebin sharing, which no other file transfer service provides.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
CubbyDrop's answer
Unlike WeTransfer, Google Drive, or Dropbox, CubbyDrop uses true zero-knowledge encryption — the server never sees your files or encryption keys. Live mode transfers files directly between devices with no size limit. Free tier includes 5GB storage, and recipients never need an account to download.

Diffyn is the platform that specializes on both change management and multi-model analysis.

CubbyDrop's answer
Privacy-conscious professionals, freelancers, and teams who share sensitive files — legal documents, contracts, financial records, medical files, API keys, or code. Anyone who needs to share files without trusting the server.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
CubbyDrop's answer
CubbyDrop was built out of frustration with existing file sharing services that claim security but can still access your files. I wanted a service where encryption happens in the browser before anything leaves your device, with zero-knowledge architecture that makes it technically impossible for the provider to see your data.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
CubbyDrop's answer
CubbyDrop is an early-stage bootstrapped product serving individual professionals and small teams who prioritize privacy. We're focused on organic growth through word of mouth.
