Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
PagePanda's answer
PagePanda started from a simple problem: saving articles is easy, but actually returning to read them is much harder. It was built around helping readers rediscover their saved content, make reading more enjoyable, and gradually work through their backlog.
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.
PagePanda's answer
PagePanda is primarily a consumer app for individual readers, so it doesn’t have traditional enterprise customers. Its users include students, developers, researchers, professionals, and people who regularly save long-form content to read later.
