As answered by people managing SecureFollow.app and Diffyn.
SecureFollow.app's answer
SecureFollow is privacy-first by design: it analyzes your Instagram relationships using your official Instagram data export (ZIP) and runs 100% locally in your browser. No login, no password, and no uploads — your files stay on your device. It’s a simple, safe alternative to unfollower tools that require account access or automation.
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.
SecureFollow.app's answer
Many unfollower tools ask for Instagram credentials or rely on automation, which can be risky. SecureFollow avoids that entirely by using the user’s own official export (ZIP) and processing it locally. You get clear results (unfollowers, not-following-back, mutuals) without handing over your account or data.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
SecureFollow.app's answer
SecureFollow is built as a modern web app / PWA using JavaScript/TypeScript and runs entirely client‑side in the browser. It parses the Instagram export (ZIP/JSON) locally and uses browser storage for optional saved history. The site is delivered via a CDN (Cloudflare) for fast global access, with no server-side processing of user exports.

SecureFollow.app's answer
SecureFollow is for Instagram users who want to check unfollowers safely: creators, influencers, community managers, and privacy-conscious users. It’s especially useful for anyone who doesn’t want to trust third‑party apps with their Instagram login.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
SecureFollow.app's answer
SecureFollow started as a response to a common problem: most “unfollowers” apps require logging in with your Instagram account. We wanted a safer option, so we built a tool that works from the official Instagram data export and runs locally in the browser. The goal is simple: useful insights with zero credential sharing.
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.
