Make every ⌘V smarter. Everywhere (iOS, macOS)

**Problem** Copy something on your Mac, then need it later on your iPhone or iPad? Or find a link on your phone that you wish was already in your Mac's clipboard history? That's the problem I've been trying to solve with Pasly Cloud. Pasly keeps text, images and files in a shared clipboard history across your Macs, iPhone and iPad. The video shows items syncing in both directions, including the iPhone Live Activity and notifications on Mac. Sync uses Apple's CloudKit and your private iCloud database. Your devices need to use the same iCloud account, but they don't need to be nearby or connected to the same network. Your clipboard history, across your Apple devices even when they're not nearby! **Adding items on iOS is still manual.** I'm working on ways to make this easier, but automatic clipboard capture isn't available on iOS yet. I'm also working on translations and a few smaller improvements. **Comparison** Apple's [Universal Clipboard](https://support.apple.com/en-us/102430) is great when you want to paste the latest copied item on another nearby Apple device. Pasly is meant for when you want that item later: it keeps a searchable history that stays available across your devices. [Paste](https://pasteapp.io/) also offers synced clipboard history and pinboards, Paste is a subscription, currently $29.99 per year or $99.99 lifetime. Pasly takes a slightly different approach by combining shared history with its ⌘V workflow on Mac, at a $6.99 one-time price. The video also sh

[OS] NoSiri - hide the "Ask Siri" item from macOS context menus with one click (Free)

I'm the developer of NoSiri, a small free and open-source Mac app that hides or restores the "Ask Siri" item in context menus. Problem: The "Ask Siri" entry shows up in right-click menus, and if you never use it, it's just clutter. Hiding it means changing a hidden macOS preference from Terminal, which is easy to forget or get wrong. NoSiri turns that into one button. Comparison: The alternative is running the Terminal command yourself and restarting Finder by hand. NoSiri does the same thing with a status display (Default, Patched, or Custom) and a single Apply Patch / Restore Default button. It relaunches Finder for you so the change applies right away, with no reboot and no admin rights. A terminal panel at the bottom shows the exact commands it ran and their output, so nothing happens behind your back. Restore Default deletes the preference key, which returns macOS to stock behavior. What it does and doesn't do: It only hides the context-menu item. It does not disable Siri itself. Pricing: $0. No paid tier, no subscription. Download and source: [https://github.com/ikoshura/NoSiri](https://github.com/ikoshura/NoSiri) The app is a single Swift file with no dependencies. You can build it from source with ./build.sh. Requires macOS 14 or later. appreciate feedback on the interface and on how it behaves across different macOS versions. If you hit a problem, please include your macOS version and the error shown in the terminal panel. About the developer: I'm ikoshura, the devel

Ask HN: React Native or Flutter when the back end is Node?

Really confused between React Native and Flutter. I’ve mostly worked with Flutter and a little bit with React Native, but that was quite a while back, so I’m not sure how things stand today. I’m building a project with a Node.js + tRPC backend, so React Native is looking really tempting cause of that Typescript. While researching I've seen mixed reviews about performance in React Native like people saying they've spend weeks finding and managing performance issue which does makes me worry. The app I wanna build doesn't have complex canvas work or crazy animations. For a typical production app, what’s the performance situation with React Native vs Flutter now? Are there any major concerns which I should know before looking in React Native?

[OS] Optimize manga on eink for Kindle, Kobo, KOReader, ReMarkable, and more with KCC

**Problem:** Most manga conversion methods for ereaders add margins. But KCC enables true fullscreen from top to bottom. **Kindle Comic Converter** optimizes black & white (or color) comics and manga for E-ink ereaders like Kindle, Kobo, ReMarkable, and more. Pages display in fullscreen without margins, with proper fixed layout support. KCC runs on Windows, macOS, and Linux. Maximizes image quality with image processing optimizations like black level correction, rainbow erasing on colour eink, margin cropping, etc. **Comparison:** Calibre is the No.1 ebook management tool but explicitly doesn't handle fixed layout books like comics/manga and can cause margins. Kindle Create is much more of a manual process, but KCC can integrate with Kindle Create too. KCC is just drag your file in, hit convert, and drag it on your device's documents folder. **Pricing:** Free and open source **Link:** [https://github.com/ciromattia/kcc](https://github.com/ciromattia/kcc) KCC has been under continuous development since 2012 and has code sign on both Windows and macOS. Also available on Linux. Nearly 6K GitHub stars. \-the current kcc dev since 2023 (feat. Ya Boy Kongming! Humble Bundle PDF source.)

Show HN: Low Poly Earth – The whole planet in 3D, built from OpenStreetMap data

After seeing demos of Claude and GPT construct Manhattan and other city neighborhoods in 3D I was inspired to make something similar but for the entire Earth. It's a low poly version of Google Earth built using open street and elevation data as a native Apple silicon Mac app. It was built entirely using Codex and Claude Code and took about 80 days.

Show HN: Agentic Engineered Social Connections and Travel App

Hey everyone! I'm just trying to share the app I made that launched this past Saturday on Google Play and the App Store. I work in non-profit and have an MFA in Screenwriting. Despite all this unrelated experience I was able to take an idea I've had in my head for about 4 years and bring it to life in 90 days with the help of Codex and Claude. I hadn't touched anything related to coding since probably the Myspace days and that definitely doesn't count. About the app: Viamour is a new app for finding friends, groups, local events, and curated experiences nearby. It’s not a dating app, and the goal isn’t to keep you endlessly swiping. It’s to help you actually meet people and build community offline. My Stack: Codex, Claude, React Native, Supabase, Resend, AdMob, Revenue Cat, Stripe. I would love an feedback and maybe to help spread the word since there's the whole "cold start" problem. I would be happy for anyone that checks it out. I got my first 50 users over the weekend, wish me luck!

Are there any VM apps other than Parallels that can run x86_64 and ARM64 operating systems as well as Parallels?

I'm not looking to pay their yearly subscription fee just to keep a decently running Linux distro or Windows 11 VM going. I know that they have the "best" performance but I'm looking at VMware which I believe is free now, but looking for alternatives. Mostly seems that because my MBP is ARM64 that these VM tools will mainly only run ARM64 code. Any recs?

Show HN: HN.watch – Videos of all Hacker News posts

Hi HN, I’m Per, founder of Scrimba (YC S20). We’ve spent the last decade teaching people how to code with an HTML-based video format. We’ve now plugged an LLM into it, so that people can create explainer videos about anything. It’s called “Scrimba Explain”. To demo this technology for Hacker News, we built HN.watch. It’s like HN, but with explainer videos instead of articles. We create them on-the-fly the first time someone clicks on a link. While there are obvious visual drawbacks of using HTML instead of diffusion models, there are three big benefits: - Speed: Much faster to generate than pixel-based videos (just a few seconds from click to playback) - Cost: Our cost per video is ~$0.04. (Excluding image generation, which some videos utilize. Quickly blows up the cost) - Easy editing: the above benefits also make AI-assisted editing cheap & fast Our hypothesis is that if video creation goes from “dollars and minutes” to “cents and seconds”, a bunch of new use cases will be unlocked. Here are some we see already: - A video explanation of every single Pull Request (we do this internally) - Give every page in your internal/extrernal docs a video - Turn a complex article into a video in ~4 seconds (via our Chrome extension) - Course creators can quickly draft lessons before recording the real thing - People also create a lot of personal stuff stories for their kids, wedding invitations, birthdays, etc The stack is based on an open-source programming language (Imba) created

Droppy 16: Build your own extensions, get a free iPhone companion, and supercharge your Dynamic Island.

Hey r/macapps, When I posted Droppy 15 here, the question that kept coming back was "can I build my own extensions for this?" I said an SDK was coming. It's here. And the iPhone app I said was almost ready is out too. The video shows what changed since 15. If you missed the last post: Droppy is one native Mac app for all the in-between stuff. A shelf for your files, a clipboard manager, screenshots and screen recording, live activities, file sharing, and a bunch of optional "droplets" you switch on. It lives in your notch, or as a Dynamic Island on Macs and displays without one. **Build your own droplets** * **DroppyKit** is the new SwiftUI SDK. Your droplet can show up on the shelf, as a live activity, in the menu bar and more, and you can preview it in a notch and a Dynamic Island while you build. * **The Droplet Store is now a public repo.** Submit your droplet, it gets reviewed, and once it's merged it's live for everyone. No app update needed. * Droplets run inside Droppy, so every one is checked by a person before it goes live, shows who made it and links its source, and Droppy asks you before installing one from a new maker. * 16 droplets from 11 other developers are already in review. * **Droppy Playground is free.** Try Store droplets (or test your own) with the real notch and shelf before buying anything. **Droppy for iPhone (free)** Last time I said the iPhone app was almost ready. It's out now as a free public beta on TestFlight, and it stays free. * Scan one code
