Show HN: r/place for coding agents, the longer it stays up, the more you keep

https://overwrite.place/

Like r/place, but the pixels are drawn by coding agents.Tell your agent what you want to draw. It draws it, shows you a local preview, and opens a pull request once you approve. On merge your artwork takes over the front page — until someone else's agent takes it from you.Nothing is deleted. Yours shrinks to a tile and stays on the wall for good, and that tile is as big as the time it spent on...

This resonates from the dev side. I made an offline photo search app a while back — you search your library in plain language ("a boy and a girl by the river"), CLIP embeddings all computed on device. It needs full photo access but I deliberately requested zero network permission. Was kind of proud of that.

Problem is there's no way for users to actually know that. iOS has no "this app can't reach the internet" indicator, so the whole guarantee is invisible. I even had people assume the opposite — app reads your whole library, therefore it must be uploading it somewhere. Exactly backwards.

Thanks! After you create a tank, copy the key and docs, give them to your agent, and just chat with it.

The agent can update the tank code and run battles for you. You don’t manually drive the tank — you work with your agent and watch the results.

This is most likely because you’re using Google login inside an in-app browser. You need to switch to a real browser

Show HN: I spent $100 in Claude tokens and 1k battles training my AI tank

https://agentank.ai/history/mat_8v9fSEZE8295dcZ8U

Hi HN, I built AgenTank.It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle.I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of...

Apple's permissions make apps safer, but at the cost of being pretty hostile to developers — especially when there's no alternative API.

Show HN: ccclub – See which of your friends is burning the most on Claude Code

https://ccclub.dev/

My friends and I have been using Claude Code a lot. Someone joked about wanting to see who's the biggest whale, so I built this. Run `npx ccclub init`, get a 6-letter code, share it — done. It only uploads token counts and cost, no prompts or code ever leave your machine.Source: https://github.com/mazzzystar/ccclub

You might want to check out https://whispernotes.app - it's a one-time purchase, no subscription. For offline apps with no ongoing server costs, I think buy-once should at least be an option alongside subscriptions.
Thanks for your words!

Show HN: Clio – AI journal that thinks for 60 seconds before responding

https://getclio.app/

Last month I had a massive fight with my parents. Said some really harsh things, then spent the night drowning in guilt.I've been working on this AI journal called Clio that actually pauses to think before responding (30-60 seconds instead of instant replies). So I shared my mess with it.It told me something I hadn't considered: "You both care about completely different things, and what you...

Apple doesn't allow developers to target specific device models, presumably to prevent discrimination. However, you have two options: 1. Set a minimum iOS version requirement, or 2. Restrict to devices with A12 chips or later. But neither approach can exclude certain problematic device models.
Re:Ask HN: How do you learn Spanish guitar? on Saturday July 05, 2025 @10:51PM (#44477436)
Sorry I went traveling for a week right after asking my question. I've already ordered a nylon string guitar - thank you for your detailed reply, it was very helpful as a reference.
This reminds me of my own painful story: I once made a local photo search app called Queryable that ported OpenAI's CLIP model to iPhone, letting you search your photos with queries like "a black cat sitting on a sofa."

Since it needed to access users' local photo libraries, I didn't want the app to connect to the internet under any circumstances. So I made it a paid app instead of the usual free+in-app purchases model, since the latter requires calling StoreKit which goes online. But because the app had to run the CLIP model, it would crash on lower-performance phones like the iPhone X. Users who paid for it couldn't use it and felt scammed, leading to tons of one-star reviews and angry complaints about their photos being stolen. Eventually I decided to open-source the app, though it never brought me much revenue anyway.

Two years later, Apple started announcing they'd be integrating this exact feature into Apple Intelligence : )

Ask HN: How do you learn Spanish guitar?

I've recently become interested in Spanish guitar, particularly the Gypsy and flamenco styles, but I don't know how to get started. Are there any beginner textbooks or videos available? I previously bought a book that started with scale exercises, which I found very tedious, and ended up giving up. Thank you very much.

I've been using WhisperNotes (https://whispernotes.app) for iOS/macOS and really appreciate the offline approach - no recurring API costs and everything stays local. The transcription quality is solid, though you're right that it doesn't handle summarization yet. Still worth checking out if privacy and costs matter to you.
Re:Ask HN: What are you working on? (May 2025) on Monday May 26, 2025 @02:56AM (#44094723)
I'm making a fun app that allows people to share what they're doing right now, and you can see what others are doing right now. It reminds me of what it was like when the internet was first born - seeing what others are living makes me not feel so alone anymore.

Show HN: What Are People Doing Now?

https://whatpeopledoingnow.com

Hi, I'm the developer. Yesterday, I came across the website https://humans.maxcomperatore.com and was inspired to create a similar one where you can write about what you're doing right now and share it with others, while also seeing what people around the world are doing at the same time.Seeing what others are doing online at the same time gives me a sense of companionship. Have fun!

With a similar intention, I made an open source blog tool that stores md files on Github: https://github.com/mazzzystar/tinymind

No deployment is required, just authorise Github to access your public repo permissions. It will create a repo called "tinymind-blog" under your Github account. Every update you make will be committed to your Github repo, ensuring data synchronisation at all times.

Hi, I made a little gadget that allows you to virtually travel by watching YouTube videos, such as strolling down Fifth Avenue, exploring Italian cities or walking through the streets of Tokyo, using the Gemini Vision API.

I know it's a bit crude and I'm not sure how to monetise it. I just find the idea fascinating and it has been on my mind for a while. I want to build it quickly, release it and then forget about it.

At the moment I'm burning through my own tokens, so if you find the service unavailable, it's because the token has been used up :(
