Questions & Answers

As answered by people managing DisplaySpan and Diffyn.

What makes your product unique?

DisplaySpan's answer

DisplaySpan combines three everyday multi-monitor fixes in a native Mac menu bar app: cursor movement across blocked screen edges, automatic restoration of saved display positions, and brightness control for supported screens. Brightness keys can target the display under your pointer. Display profiles stay on your Mac, and cursor or keyboard activity is not uploaded.

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?

DisplaySpan's answer

Choose DisplaySpan when your main frustrations are a cursor getting stuck between monitors, screen positions changing after reconnecting a dock, or brightness keys adjusting the wrong display. It puts these controls in one menu bar app, with a 3-day free trial and a one-time license starting at $9.90. Try it with your own setup first: third-party brightness requires Apple Silicon and a working DDC/CI connection, and layout restoration covers screen positions.

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?

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

DisplaySpan's answer

DisplaySpan is for Mac users working with two or more displays, especially people pairing a MacBook with an external monitor or regularly connecting to a dock. It is useful for developers, designers, remote workers, and anyone who wants smoother cursor movement, a repeatable desk arrangement, and convenient brightness control. It runs on macOS 14 or later.

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?

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.
