Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
LeadVault.to's answer
Lead Vault was built after seeing agencies overpay for B2B data from tools like Apollo and ZoomInfo. The goal was simple: give agencies access to the same quality leads at a price that actually makes sense for their margins.
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.
