Auto rename downloads by AI and with your own naming rules
Hii HN! 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…
What it does
In the maker’s words, at launch
Hii HN! 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. If you want to try the extension, here's the link: https://chromewebstore.google.com/detail/cantripsai-auto-ren...

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
