So, you can assign github issues to this thing, and it can handle them, merge the results in, and mark the bug as fixed?

I kind of wonder what would happen if you added a "lead dev" AI that wrote up bugs, assigned them out, and "reviewed" the work. Then you'd add a "boss" AI that made new feature demands of the lead dev AI. Maybe the boss AI could run the program and inspect the experience in some way so it could demand more specific changes. I wonder what would happen if you just let that run for a while. Presumably it'd devolve into some sort of crazed noise, but it'd be interesting to watch. You could package the whole thing up as a startup simulator, and you could watch it like a little ant farm to see how their little note-taking app was coming along.

It's actually a decent patern for agents. I wrote a pricing system with an anylyst agent, a decision agent, and a review agent. They work together to make decisions that comply with policy. It's funny to watch them chatter sometimes, they really play their role, if the decision agent asks the anylyst for policy guidance it refuses and explains that it's role is to analyze. Though they do often catch mistakes that way and the role playing gets good results.

I was interested. Clicked the try button and just another wait list. When will Google learn that the method that worked so well with Gmail doesn't work any more. There are so many shiny toys to play with now, I will have forgotten about this tomorrow.

The method absolutely does work, but you need loyal advocates who are praising your product to their friends, or preferrably users who are already knocking on your door.

It's success theater. You need to show progress otherwise you might be perceived falling behind. In times where LoI's are written and partnerships are forged the promise has more value than the fact.

Google’s ability to offer inference for free is a massive competitive advantage vs everyone else:

> Is Jules free of charge?

> Yes, for now, Jules is free of charge. Jules is in beta and available without payment while we learn from usage. In the future, we expect to introduce pricing, but our focus right now is improving the developer experience.

Haven't tried Jules myself yet, still playing around with Codex, but personally I don't really care if it's free or not. If it solves my problems better than the others, then I'll use it, otherwise I'll use other things.

I'm sure I'm not alone in focusing on how well it works, rather than what it costs (until a certain point).

nathan_compton · 1h ago
I tried using Codex today and it sucked real bad, so maybe Jules will actually be good?

That's all good and well but its takes time to compare the products. And people are rarely willing to use paid product for comparison.

> That's all good and well but its takes time to compare the products

Hence many of us are still busy trying out Codex to it's full extent :)

> And people are rarely willing to use paid product for comparison.

Yeah, and I'm usually the same, unless there is some free trial or similar, I'm unlikely to spend money unless I know it's good.

My own calculation changed with the coming of better LLMs though. Even paying 200 EUR/month can be easily regained if you're say a freelance software engineer, so I'm starting to be a lot more flexible in "try for one month" subscriptions.

xiphias2 · 2h ago
I haven't read too much from others, but personally for me Codex online form was the biggest productivity boost in coding since the original Copilot.

Cursor just deleted my unit tests too many times in agent mode.

Codex 5x-ed my output, though the code is worse than I would write it, at this point the productivity improvement with passing tests, not deleting tests is just too good to be ignored anymore.

ijidak · 2h ago
What do you mean by "online form"?
diggan · 2h ago
Codex seems to also be available via CLI (https://github.com/openai/codex) as well as via the web (https://chatgpt.com/codex).
miki123211 · 1h ago
I just noticed that this is definitely true for me, but not if the product is pay to go.

I have far fewer qualms about spending $10 on credits, even if I decide the product isn't worth it and never actually spend those credits, than about taking a free trial for a $5 subscription.

I feel like this (and I know it's big tech tradition) had the same economic effect as dumping.

Google has been offering you "free inference" for more than a decade. People who never work there are simply not aware of how thorough soaked in machine inference many Google products are, especially the major ones like web search, mail, photos, etc.

This is standard startup play. Have a free beta stage and then transition into pricing.

There are some limits:

spongebobstoes · 1h ago
5 tasks per day is low enough to be roughly useless for serious work
sigmar · 48m ago
It isn't "5 prompts." A single task is more like a "project" where you can repeatedly extend, re-prompt, and revise.

You're the product here, though.

EDIT: legal link doesn't work here (https://jules-documentation.web.app/faq#does-jules-train-on-...)

> No. Jules does not train on private repository content. Privacy is a core principle for Jules, and we do not use your private repositories to train models. Learn more about how your data is used to improve Jules.

I read that a couple of times. It sounds vaguely clever and a bit ominous, but I have no clue what it means. Can you explain?

Google products had had a net positive impact on my life over, what is it, 20 years now. If I had had to pay subscription fees over that span of time, for all the services that I use, that would have been a lot of very real money that I would not have right now.

Is there a next step where it all gets worse? When?

They're going to make so much money when nobody knows how to code or think anymore without the crutch.

I'll just put this here:

> And so it is that you by reason of your tender regard for the writing that is your offspring have declared the very opposite of its true effect. If men learn this, it will implant forgetfulness in their souls. They will cease to exercise memory because they rely on that which is written, calling things to remembrance no longer from within themselves, but by means of external marks.

> What you have discovered is a recipe not for memory, but for reminder. And it is no true wisdom that you offer your disciples, but only the semblance of wisdom, for by telling them of many things without teaching them you will make them seem to know much while for the most part they know nothing. And as men filled not with wisdom but with the conceit of wisdom they will be a burden to their fellows.

- Plato quoting Socrates in "Phaedrus", circa 370 BCE

But did you memorize that quote, or was it sufficient to know its gist so you could google it?
Avicebron · 2h ago
At least with writing it's fairly easy to implement on your own with little more than what most people would have available in a rudimentary survival situation. It'll be a tough day when someone goes to sign into their GoogleLife (tm) and find out that they can't get AI access because "precluding conditions agreed to upon signing"
falcor84 · 2h ago
As I see it, the solution to this is to invest in open source. As for a "survival situation", a solar-powered laptop with a locally running LLM would definitely be the first item on my list.

-__---____-ZXyw · 2h ago
But are you filled with wisdom, or with the conceit of wisdom?
brendoelfrendo · 41m ago
Hm, I think Plato is largely true; not in the sense that writing is a harmful crutch, but in the sense that simply being able to read something is not a substitute for knowing it. I think we can see that at play here on HN and on the larger internet all the time: people who read a paper or article, and then attempt to discuss it, without realizing that their understanding of the material is entirely incorrect. These are "men filled not with wisdom but the conceit of wisdom," and they lack the awareness to understand that they don't understand.

In other words it is not the writing that is harmful, but the lack of teaching.

The copy though: "Spend your time doing what you want to do!" followed by images of play video games (I presume), ride a bicycle, read a book, and play table tennis.

I am cool with all of that but it feels like they're suggesting that coding is a chore to be avoided, rather than a creative and enjoyable activity.

habosa · 25m ago
So absurd. As if your boss is going to let you go play tennis during the day because Jules is doing your work.

If all of these tools really do make people 20-100% more productive like they say (I doubt it) the value is going to accrue to ownership, not to labor.

diggan · 3h ago
> it feels like they're suggesting that coding is a chore to be avoided, rather than a creative and enjoyable activity

I occasionally code for fun, but usually I don’t. I treat programming as a last-resort tool, something I use only when it’s the best way to achieve my goal. If I can achieve some thing without coding or with coding, I usually opt for the first unless the tradeoffs are really shit.

beatboxrevival · 3h ago
I think they are suggesting that you can focus on the code that you want to write - whatever that is. Especially since the first line is, "Jules does coding tasks you don't want to do." I took the first image as being someone working on the computer. Or, take back your time doing whatever you want - e.g. cycling, table tennis, etc.

If you work at a company where there's a byzantine process to do anything, this pitch might speak to you. Especially if leadership is hungry for AI but has little appetite for more meaningful changes.

That's a nuance worth exploring. The world is being optimized for clockwatchers who want to do their work with the least amount of effort. Before long (if not already) people who enjoy their craft, and think of their work as a craft, will be ridiculed for wanting to do it themselves.

There is one clock you should be watching regardless, which is the clock of your life. Your code will not come see you in the hospital, or cheer you up when you're having a rough day. You wont be sitting around at 70 wishing you had spent more 3am nights debugging something. When your back gives out from 18hrs a day of grinding at a desk to get something out, and you can barely walk from the sciatica, you wont be thinking about that great new feature you shipped. There are far more important things in life once you come to terms with that, and you will learn that the whole point of the former is enabling the latter.

bmgxyz · 2h ago
Writing code _has_ helped me feel better on some bad days. Even looking back at old projects brings me contentment and reassurance sometimes. On its own, it can't provide the happiness that a balanced life can, but craft and achievement are definitely pleasing. I would consider it an essential part of a good life, regardless of what the actual activity is.

This is different from meaningless work that brings you nothing except a paycheck, which I agree is important to minimize or eliminate. We should apply machines to this kind of work as much as we can, except in cases where the work itself doesn't need to exist.

esafak · 2h ago
You could say the same about every job, so you are really arguing against jobs in general. Who's going to help you fix your sciatica if your doctor and physical therapist think like that?
insin · 2h ago
The opposite of a clockwatcher isn't a workaholic, it's someone enjoying writing code and the collaboration, problem solving and design process which leads to what you end up writing, and enjoying _doing it well_ inside normal work hours, remarking at how quickly the clock is going when they do check it.

Both Google and Microsoft have sensibly decided to focus on low-level, junior automation first rather than bespoke end-to-end systems. Not exactly breadth over depth, but rather reliability over capability. Several benefits from the agent development perspective:

- Less access required means lower risk of disaster

- Structured tasks mean more data for better RL

- Low stakes mean improvements in task- and process-level reliability, which is a prerequisite for meaningful end-to-end results on senior-level assignments

- Even junior-level tasks require getting interface and integration right, which is also required for a scalable data and training pipeline

Seems like we're finally getting to the deployment stage of agentic coding, which means a blessed relief from the pontification that inevitably results from a visible outline without a concrete product.

85392_school · 2h ago
> Also, you can get caught up fast. Jules creates an audio summary of the changes.

This is an unusual angle. Of course Google can do this because they have the tech behind NotebookLM, but I'm not sure what the value of telling you how your prompt was implemented is.

I guess the idea is vibe coding while laying in bed or driving? If my kids are any indication of the generation to come, they sure love audio over reading.
CobrastanJorji · 1h ago
Is the "asynchronous" bit important? How long does it take to do its thing?

My normal development workflow of ticket -> assignment -> review -> feedback -> more feedback -> approval -> merging is asynchronous, but it'd be better synchronous. It's only asynchronous because the people I'm assigning the work to don't complete the work in seconds.

ukuina · 18m ago
Other Agentic tools run for 10-30min based on model, task complexity and the number of dead ends the LLM get into.

I think that's the point AI agents are trying to sell. Spend more time on the type of coding tasks you want to do, like coding cool new code, and not the tasks that you don't want to do.

I really want to try out Google's new Gemini 2.5 Pro model that everyone says is so great at coding. However, the fact that Jules runs in cloud-based VMs instead of on my local machine makes it much less useful to me than Claude Code, even if the model was better.

The projects I work on have lots of bespoke build scripts and other stuff that is specific to my machine and environment. Making that work in Google's cloud VM would be a significant undertaking in itself.

Can it resolve merge conflicts for me? My least favorite programming task and one I haven't seen automated yet.
mock-possum · 55m ago
I’d love to see it if that’s possible - merge conflict cleanup can be some of the hardest calls, imo, particularly when the ‘right’ merge is actually a hybridized block that contains elements from both theirs and mine. I feel like introducing today’s LLM into the process would only end up making things harder to untangle.

Any coding solution that doesn’t offer the ability to edit the code in an IDE is nonsense.

Why would I ever want this over cursor? The sync thing is kinda cool but I basically already do this with cursor

diggan · 3h ago
Heh, personally I'd say any coding solution that lives inside an IDE is nonsense :P Funny how perspectives can be so different. I want something standalone, that I can use in in a pane to the left/right of my already opened nvim instance, or even further away than that. Gave Cursor a try some weeks ago but seems worse than Aider even, and having an entire editor just for some LLM edits/pair programming seems way overkill and unnecessary.
ryandrake · 2h ago
Ideally, it would be built in to [my IDE of choice]. So I neither have to have a separate browser window open, copy/pasting, or have a separate IDE open, copy/pasting. Having it as a standalone tool makes as much sense as having a spell checker that is a separate browser window running a separate app from the word processor you are using to write your letter. Why?

No privacy documentation? No terms of use? Is this a joke?

Here’s a “reasoning trace:” You want to use Gemini? Why would you if AI Studio is way better? Oh, privacy? Except to get privacy in Gemini, you need to turn off Gemini Apps Activity, which deletes your entire chat history… (forcing you to manually copy paste every input and output into notes).

OpenAI might be a bunch of monopolistic assholes, but at least you can (manually opt out of hidden) training ChatGPT without losing your entire chat history.

Another big reason not to use AI Studio, even though it’s free and way better than the PAID Gemini offering, is you can’t use it for anything that competes with it. It being general intelligence. Meaning this is yet another instance of the “you can’t use our AI for anything” legal term trend. Luckily, they don’t explicitly mention Gemini app in their “Additional API Terms” here:

[1] https://ai.google.dev/gemini-api/terms

> You may not use the Services to develop models that compete with the Services (e.g., Gemini API or Google AI Studio).

Then you go and use Google search, and it tries to send you to fucking AI Mode in a different app, can you guys pick a lane ? Am I supposed to use Gemini with no chat history, AI studio for the free better app and get brain raped and sued by a megacorporation, or Google “AI Mode” and get redirected back and forth from my browser a billion times?

And what’s the cost to user experience for switching between three different apps with different rules and maintaining three interfaces?

Which brings me back to Jules. How do we know what’s the privacy policy for Jules? How do we know if we’re “allowed” to use it for AI?

Businesses using this type of thing need to return two booleans confidently: are they training on our private codebase? Are they gonna ban or sue us for breaking the rules?

Linking to the general Google terms and privacy pages doesn’t really inspire much (any) confidence in the privacy aspect, and who knows if Jules counts as Gemini API thing? Are we supposed to just pray it doesn’t count as using the Gemini API even though it probably does? If Google trains on everything then how can we trust them not to do it on our code?
