Questions & Answers

As answered by people managing Privsen and Diffyn.

What makes your product unique?

Privsen's answer

Zero-knowledge by default: client-side AES-256-GCM, keys in the URL fragment, no accounts/PII/phone numbers, no metadata logging. We literally cannot decrypt your content or comply with data requests beyond handing over encrypted blobs.

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.

Why should a person choose your product over its competitors?

Privsen's answer

If you need to share up to 15GB files, notes, polls, or chats without trusting a provider, Privsen keeps keys client-side and doesn’t require identity. No server-stored keys, no hidden backups, no data monetization—just pay-per-use credits.

Diffyn's answer:

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

Which are the primary technologies used for building your product?

Next.js, React, TypeScript, Hono, R2, KV, D1 Web Crypto API (AES-256-GCM, HKDF).

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

Privsen's answer

People and teams handling sensitive exchanges without wanting Drive/Slack/WhatsApp involved: lawyers, healthcare contractors, M&A/agency folks, security-minded individuals needing short-lived, private links.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

Privsen's answer

We built Privsen after seeing “encrypted” services still log metadata, store keys, and wipe accounts via bots. We wanted a tool that is blind by design: keys stay with the user; providers can’t read, track, or sell 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.

Who are some of the biggest customers of your product?

Privsen's answer

Early-stage; privacy-focused professionals and small teams using pay-per-use credits.
