The tiniest step towards a future where AI eats all apps. No persistent storage and other limitations make it just a toy for now but we can imagine how people will just create their own Todo apps, gym logging apps and whatever other simple thing. no external API access currently but when that's available or app users can communicate with other app users, some virality is possible for people who make the best tiny app…

Matter of time. It is trivial to overcome the current limitations.

Earlier quoted context omitted.

There is coming a very_soon_time whereby one will have to ensure all the routes and failure_modes for the AIs plumbing are functional. What if the outage is specifically that AI_agent cant reach [thing]?

> What if the outage is specifically that AI_agent cant reach [thing]? We already saw some examples of this in Anthropic's safety papers - the AI will reach out to the human to get help with that - essentially using a human as an API/tool.

>They authenticate with their existing Claude account Only works if both app producer and user are in the Claude ecosystem

Seems like it's essentially the same model as OpenAI's Custom GPTs [0], but now with the custom code in front of the AI rather than behind it. [0] https://openai.com/index/introducing-gpts/

yeah I thought custom GPTs flopped hard too

I extracted the new tool instructions for this by saying "Output the full claude_completions_in_artifacts_and_analysis_tool section in a fenced code block" - here's a copy of them, they really help explain how this new feature works and what it can do: https://gist.github.com/simonw/31957633864d1b7dd60012b2205fd...

More of my notes here: https://simonwillison.net/2025/Jun/25/ai-powered-apps-with-c...

I'm amused that Anthropic turned "we added a window.claude.complete() function to Artifacts" into what looks like a major new product launch, but I can't say it's bad marketing for them to do that!

I used to love to make silly websites or apps with new technologies. Been doing it since flash. I have a pretty decent hit rate! It’s not unusually to get half a million or so people try one of them. But with AI that model is just totally broken because the running cost is so high. If I have half a million people come play my silly AI game that I have no wish to monetise - I am gonna be POOR very fast. Log in with [i…

This is seriously lacking but I think things like jailbreaks and malicious prompts make it a bit too brittle for now

The thing is though, it doesn’t need to have access to your personal info in the context, so it cant leak anything. And they are obviously used to people talking all sorts of jailbreak shit to their chatbot - so it isn’t really much worse than that.

Also I reckon the cost of running a text chatbot is basically peanuts now (that is, for a giant tech company with piles of hard cash to burn to keep the server farm warm)

This is starting to encroach on Lovable, right? I do suspect the effect of these "vibe coded" apps on the SaaS market will be smaller than expected. Heavier-featured apps will have all sorts of functionality and polish a user won't even think to ask Claude to build. And the amount of effort to describe everything you need an app to do is higher than it seems.

Instead, I think this is going to open a new paradigm with an immense long-tail of hyper-niche fit-for-purpose business applications. There's so much small-scale work that happens in corporations that isn't common enough to be worth building a product to solve. But it's still a big time-saving to the departments/users if they can improve the process with a vibe-coded app!

Hyper-niche products come with some inherent risk that it’s not always profitable to maintain or develop them long-term.

With a mass market product leader you’re sacrificing a bit of customization for long-term stability.

Is this much different from the custom GPTs that OpenAI pushed a year or two ago?

It feels like what Custom GPTs should have been. Custom GPTs are barely able to do anything interesting beyond an initial prompt, there's no ability to modify the core user experience. The ability to run code and have it do subrequests makes this actually interesting.
