How would you describe the primary audience of your product?

Diffyn's answer

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

Swift-Slide's answer:

Swift-Slide is designed for people who need to update or reuse presentation materials but only have a PDF or image.

Typical use cases include business professionals revising proposals and reports, educators updating teaching materials, and students adapting slides for presentations. It is especially useful when only a few text changes are needed and recreating the slide would be unnecessary work.

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.

Swift-Slide's answer:

Swift-Slide is an independently developed service focused on a practical problem: making changes to presentation materials when only a PDF or image is available.

During the first two weeks after launch, I reviewed visits and usage patterns and suspected that requiring registration before trying the conversion could be a barrier. I added a registration-free one-page trial so people could see the result with their own files first.

I also redesigned the public pages to explain real use cases more clearly. The service continues to evolve through usage observations and feedback.
