As answered by people managing TracePDF and Diffyn.
TracePDF's answer
A screenshot tool gives you images. Trace gives you a document. Every capture gets a heading and a description, pages are ordered and numbered, and the export has a cover page and footer—so what you hand over reads like documentation rather than an attachment dump.
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.
TracePDF's answer
Most screenshot extensions stop at capture and annotate. Trace goes further—with cover pages, screenshot descriptions, drag-and-drop organization, numbered steps, page numbering, custom footers, and watermarks, it turns scattered screenshots into a report you'd actually want to send. If you've been stitching screenshots into a doc by hand, Trace is the tool you've been missing—install it and turn your next screen capture into a PDF report worth sharing.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.

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.
