I'm building YouTility. A macOS menu bar app that watches your screenshots folder and renames every file using on-device AI. Screenshot 2026-06-02 at 11.32.41.png → stripe-dashboard-revenue-june.png Silent. Instant. Private. No API cost. #swiftui #buildinginpublic #macos

YouTility has no dock icon. No main window. No visible presence at all. That's not an oversight, it's the entire design. It lives in your menu bar. You take a screenshot. The file gets renamed. You never touch the app. The best utility is the one you forget is running. #macOS

@v_pradeilles Thank you so much 🙏!

ok let’s try this new 5.6 Sol model

The AI in YouTility costs exactly $0 to run. I'm using Apple's Foundation Models; on-device AI built into macOS 26. No API key. No per-rename bill. No data leaving your Mac. Every screenshot rename happens locally, privately, instantly. #buildinginpublic #swiftui #ondeviceAI

@PiotrekJeremicz @binding @PiotrekJeremicz I enjoyed your presentation!

@SystemsWithLee @binding See you soon!

Excited to share that I'll be speaking at the Swift Surat Online Meetup this Saturday! 🎉 I'll be diving into SwiftUI data flow - covering @State, @Binding, and going a step further into Environment, Preference and Container Values. 📅 Saturday, 11th July, 4-6 PM IST 👉 Register here: luma.com/zonymtk9 #SwiftUI #iOS #SwiftSurat

@martingranadosg Small world - looks like we've got the same taste in menu bar icons 👀 I'm building YouTility, an on-device AI screenshot renamer for macOS. Check it out: youtility.systemswithlee.com

weekend project update screenshotter: compresses screenshots for agents and now adds companion text via macOS accessibility (opt-in) for more/better context like codex appshots, but for any local app tested with pi, claude and codex. `npm i -g @marttinn/screenshotter`

@MacdevM Congratulations!🎉!

Finally finished my master degree in Artificial Intelligence🎓 New target : diving into PhD I know many people says that studying doesn’t add much to your life, but for me, it has given me too much, I truly love researching, The imbalance of studying while working 9-5 + increasing my own business is very tough, but not impossible, right?

@sindresorhus I think an all-in-one is better. That's my opinion though.

I don't understand the logic. Instead of adding Codex support to the well working native ChatGPT app, they replace the ChatGPT app with a renamed Codex (Electron app). Still eats my battery in an hour.

@hellomacfolio Woaaaah!

fun fact: the waveform on the Apple Voice Memos app icon literally says the word “Apple”

@MaxHirsch13 You are forgiven :)

Does my desktop make me psychotic or am I just a builder trying to perfect UGC?

@CarlosBBuild Couldn't agree more!

A big perk of iOS development, Working with SwiftUI every day.

@emrdgrmnci @jacobtechtavern I've just learnt this from you. Thanks!

@jacobtechtavern wait, what! The most capable model 'Fable' doesn't even know inflection?!?!

Throwbackthursday to the best SwiftUI I ever wrote Fable ain't got sh*t on me

@devnarware Great stuff! Sean Allen?

@heyitzami @sindresorhus Today I learnt.

@sindresorhus fwiw, these type of ratings usually get removed if you flag them to apple at least they've done it 3 times so far to me

Thank

Needed to name this app. AI gave me: Fileward, Tidyshot, Vaultly, Neatr, etc. None of them felt right. Then I thought: YouTility. Your utility. Built around how you work. Took 30 secs to decide. Sometimes the right answer only arrives after you've sat with all the wrong ones

@roudyhermez I'm building a macOS automatic screenshot renamer using Apple's on-device model. Should be out by end of July.

I’d love to connect with more iOS and macOS developers 👋 Whether you’re building apps, experimenting with SwiftUI, shipping side projects, or working on something cool for Apple platforms, let’s connect 🤝 #iOSDev #macOSDev #SwiftUI #IndieDev

@roudyhermez It helps with idea validation.

Besides gaining followers, what is the point of building in public?🤔
