We've built a Chrome extension called Cantrips.ai that auto generates meaningful filenames for pdf, txt, and docs downloads.

It has tailored formats for major file types like papers, books, financial reports, etc. For example, a paper is always formatted as download date - title - first author's last name - area, so the filename would be 20250208 - Attention Is All You Need - Vaswani - LLM instead of 1706.03762 from arXiv.

We are also developing a feature where users can add or adjust their file naming preferences. For example, if you like underscores and download meeting memos a lot, you can add meeting memos = interviewee's name_company_position_topic_date.

The reason to build this extension is that my desktop is buried with meaningless and odd filenames, so I often can't find which is the one I want. I have to go to that website and download it again, sometimes the repetition number amounting over (10). More importantly, I desperately want my desktop/finder to look tidy. It feels great when everything is organized, but I don't want to handle the renaming in the mid of my research (and I become a bit lazy later :<

Note that the extension hasn't supported downloads from some websites like Github due to technical complications. As a first-time dev, I just realized even a small tool can take much time... but we assume a similar preference feature can be applied to other productivity tools like folder organization or website bookmarks. Happy to get suggestions and learn if you really need such tools.
