because you can't rely on anything from them same for Antigravity, feels abandoned only surprising product that feels non google for me is Google Stitch https://stitch.withgoogle.com/

that's because it's an acquisition ( http://usegalileo.ai/ )

Ah that makes a lot of sense now.

Just...write longer messages. Maybe it is age but I've written huge forum such as on HN all from my phone often with multiple tabs open to source various links for foot notes. When I type for an LLM, I will type a lot too if needed and will often even type a little, wait to think, then continue, over the course of like 15 minutes even, so that the intention of the prompt is correct since that saves much more time and…

I've been coding on Android for a few months, mostly while walking around outside or showering. I'm on a mix of Tailscale + Termux + ssh server + tmux + codex CLI, Tailscale is great. I think you may be able to optimize your workflow more by drafting your prompt in ChatGPT first; get it to expand out the intent for you. Doing that has made phone coding a lot more tolerable for me. I like to think that I've given phon…

I was thinking about this, don't you think having everything in a terminal on a phone screen is a bit clunky to type in? Ideally I'd want it to be a clone of the official iOS apps from these AI companies with good mobile features like copy paste, smooth scroll, etc. Looks like the article's ChatGPT Codex functionality is in Android as well.

It's a lot easier to write long messages on a phone with something like Whisper.

I'm not sure about others but I can't coherently voice my thoughts through speech alone as I'd want to think and revise the message, so I generally don't use voice transcription with AI.

I haven't found that to be an issue. Just say what revisions you want. Once you're done, paste it into an LLM to clean it up into a usable prompt.

I am not sure I understand the time savings you're describing here. Do you mean you saved the "time to write prompt into the text input box" because you got to do that sooner from your phone rather than write down your idea and do it when you got back to your computer? Wouldn't you be doing the exact same thing had you been sitting at your computer when you had the idea? Perhaps the person who wrote that had the mind…

You can use STT and include a workflow that automatically extracts the requirements (filters all the um's, ah's, pauses) and it becomes more like an interaction where you act as the Product Owner/Manager and Codex is your Architect/Dev. At least, that's how I code through my phone. But it does require some forethought in establishing your automated workflows. I'm at the point where my entire dev system has establishe…

Sure, I too do that on the computer. Computers have microphones these days, and STT runs on my macOS as well. What was your point about in regards to my comment? I am not sure I understood you.

Yes, and /model claude-opus-4-6[1m] gets you the larger context window. Happy to help :)

Thanks for the hint, but is a large context window actually that useful? I tend to get garbage too often with a normal big context window.

IME, based on an in-house bench it's still good to about 20% on the 1M for 4.6 and 4.7 with a code base >50k loc. The trick I used before switching providers was to have it write a handoff when it hit ~18% of context and reset.

There are also many people running 4.5 with specific parameters that claim to be having luck.

I use Termius on my phone to remote and make agent do stuff while i chill or am on road. This seems useful too.

I also do this, but I find the terminal ergonomics are a little awkward on mobile. I do think termius is the best version of it I've used though

Nice to see some catch-up with Anthropic and others, but this doesn't actually offer cloud coding agents (my favorite Claude and Cursor capability). I want to code from my mobile device when my laptop is off or unavailable, pushing PRs directly to GitHub. Codex mobile only works with a desktop machine, at which point, I'll just use that machine, what's the point.

Yes it does. Codex, three dots menu: Codex cloud

Dang, I thought this was going to be integration for Codex Cloud, not the (still not available for Linux) Codex App. Not even Codex CLI, alas. You can still access the Cloud option from a mobile browser well enough but I prefer an app UI for poking at the things on the go.

Linux option for Codex App https://github.com/ilysenko/codex-desktop-linux

Mobile remote connection works, pushed the PR earlier today.

Whats crazier is that Codex is free. I thought I had to pay to even try it out but nope, you can use the desktop app or cli for free, its apparently included in the free plan. You just have to sign in to your ChatGPT account. Of course I am aware that the caveat here is that all my interaction is part of training, but I’m fine with that. Even Qwen Cli discontinued the free plan.

How much better is it than Claude? I have both but Claude sucks up so many tokens.

I found it actually thinks about architecture and tests and not just spit out code with TODO in it like Claude.

(Someone deleted a comment about why you'd want a mobile Codex app. This is the answer I wrote.) Once you've used these coding agents a lot, you develop a pretty intuitive feel for how they work, what they're capable of, what they're good at, and where their weaknesses are. Hopefully, you're already pretty familiar with the code base you're working on. Combining the two, this means you can get quite far essentially "…

Sometimes I get random inspiration for an idea while out on a walk or otherwise away from the computer. It's really nice to be able to throw a couple instructions out there, let your agent run with it, and see what it came up with later. Sometimes I do this 3-5 times before returning to my computer. IMO it's really nice to be able to start from X% done rather than 0% when I finally do sit down to review/iterate on the code.
