Cala HQ's answer
CalaHQ is primarily built for small and growing companies, especially remote and international teams. It is commonly used by founders, operations managers, office managers, People teams and team leads who are responsible for approving leave and planning team availability.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Cala HQ's answer
We built CalaHQ because managing time off should not require a dedicated HR department.
Many small teams still rely on spreadsheets, emails and chat messages to track leave. That works until requests are missed, balances become unclear and nobody has a reliable view of who is away.
CalaHQ was created to give those teams a proper system without turning leave management into another complicated HR project.
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.
