Axessibly's answer
My ideal audience consists of everyone who builds the web: developers, freelancers, and digital marketing agencies. However, we also cater to strategic roles like PMs and UX/SEO teams, as well as SMEs and large corporations that need to monitor the accessibility of their digital assets consistently and intuitively.

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Axessibly's answer
The story behind Axessibly stems from the desire to make digital inclusion a process accessible to everyone, not just experts. I saw how new European regulations were challenging many organizations, and I decided to create a tool that simplified this transition, turning a technical obligation into an opportunity to improve the overall user experience.
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.
