As answered by people managing Research Master AI and Diffyn.
Research Master AI's answer
I’m well aware this space is highly competitive, and people will likely compare it against Perplexity, Gemini, ChatGPT Deep Research, and many similar tools. That’s completely fair. I don’t expect it to replace all of them. What I aim to build is a product with a much clearer workflow focus: starting from a rough research request. Users don’t need domain expertise or advanced prompt engineering skills. Using plain natural language, they can generate comprehensive, well-structured, cited long-form professional reports that serve as a solid foundation for decision-making.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Research Master AI's answer
It’s simpler to use, more streamlined to operate, professional in output yet more affordable.
Diffyn's answer:

Research Master AI's answer
Founders, product managers, cross-border marketers, investors & analysts, students and researchers — anyone with research needs is the target user of my product.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Research Master AI's answer
The basic idea came from a problem I kept having myself. A lot of AI research tools are good at giving quick answers, but when I wanted to use the result for something more serious, like market research, product planning, investment notes, or an internal deck, I still had to spend a lot of time cleaning it up. The answer would usually be useful, but not quite usable. I had to reorganize the structure, check the sources, add missing angles, and figure out which claims I could actually trust. So I started building something that is less like a chatbot and more like a research report generator.
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.
