As answered by people managing Diffyn and IQPage.
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.
IQPage's answer:
Most AI reading tools stop at summaries. IQPage adds bias detection, which flags loaded language and editorial framing in news articles. It also lets you compare how up to 3 different sources cover the same story. Everything happens inside the tab you're already reading, no copy-pasting, no switching windows.
Diffyn's answer
Diffyn is the platform that specializes on both change management and multi-model analysis.
IQPage's answer:
IQPage is built specifically for reading the web, not for chatting or writing. It works on any site, Reuters, ArXiv, Medium, Wikipedia, GitHub, and uses Claude AI by Anthropic for high-quality, context-aware responses. Free plan available with no credit card required.

Diffyn's answer
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
IQPage's answer:
Journalists, researchers, students, and anyone who reads a lot of web content and wants to think more critically about what they're reading, not just get a TL;DR.
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.
IQPage's answer:
Built by a solo founder who was tired of switching tabs every time he wanted to understand an article. Eight months of building, three Chrome Web Store rejections, and a lot of iteration later, IQPage is live.
