Ubic's answer
Ubic brings parallel dialing, CRM-connected prospect lists, call qualification and follow-up workflows into one browser-based workspace.

Ubic's answer
Ubic is designed for B2B sales teams that prospect by phone: SDRs, business development representatives and sales managers. It is especially relevant when representatives work through prospect lists from a supported CRM or CSV file and managers need to organize calling activity, qualification and follow-up. Teams should check the supported objects and synchronization behavior of their CRM connector before adopting it.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
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.
