This seems to be a wrapper around LangAgents that can be linked to iMessage. I would not say the agents "live in iMessage," rather that they interface through iMesssage.

You can find a bit more on what's (likely) behind this in the github repo: https://github.com/photon-hq/flux

(NB: the deployed version may not be exactly the same as the code in the repo)

I couldn't figure out where to go from the homepage. Eventually I spotted the grey-on-black GitHub link but that took me to an organization page, not a repository.

Here's the repo for anyone else who didn't find it: https://github.com/photon-hq/flux

Key detail from the README to help understand what's going on:

  Now text +16286298650 from your phone to interact with your agent!

So photon are operating a currently free relay service at fluxy.photon.codes (that's the address that flux talks to). You register your own phone number, then any time you send a message from your number to their +16286298650 they pass it back to your agent.

... but that means your agent needs to stay connected and running on a server somewhere. That's what this command does:

  flux run --prod

It stays running and maintains a connection to their relay and triggers your agent code any time you send a message to their number.

Based on https://github.com/photon-hq/imessage-kit my best guess is that Photon achieved this by running a Mac server somewhere that scripts iMessage via AppleScript against their own Apple ID account that owns that +16286298650 number.

Question for danielsdk: does your paid enterprise plan involve you running a Mac that's signed into a separate iCloud account that's assigned the phone number that your paying customer wants to use?

I tried this and the flow is sketchy UX even if it’s probably not malicious. It opens Messages, has you send a code to a number they control, and that “verifies” you. Probably to multiplex many chats on one phone number. That’s not a takeover by itself (you’re not forwarding a bank/Apple 2FA), but it’s sketchy. It also doesn’t work. It said hello and stopped replying.

I want to know what this is and what it does before I give it permissions.

Hi! I'm sure this is very cool, but want to know what this does before I try it. I typed in the chat: what does this do? Will you build me an agent behind a phone number I can chat with? And it tried to open up iMessage which I denied because IDK in the first place what this is.

I made an interface to a Perplexica instance over Telegram (which I use constantly through the day) a few months ago, but actually haven't used it much as honestly the quality just isn't as good as Perplexity. It does seem the logical next step is to switch to something with more raw agent-like access.

I asked it to build me a weather machine and it's responding to me like a teenager.

AI: Authentication successful! Go back to the webpage to continue.

Me: Hey!

AI: yooo whats good!! u got any weather stuff u wanna chat about or just saying hi?

Me: how’s the weather in New York City

AI: ohh nah i don't have real-time data so i can't tell u the actual conditions rn! but if u check like weather.com or just search "nyc weather" u'll get the live stuff instantly tho if u tell me whats goin on there rn i can get HYPED abt the atmospheric conditions!! like is it humid?? what's the pressure doin??

I asked it to build an app to track water consumption and medication. It can’t track anything. After logging “water consumption” and “taking medication” I asked it how much water I’d had and when I’d taken medication. It replied “mhm thats whats up” (like that - lowercase and no apostrophes)

Is that expected behaviour?

The tiresome bro-speak is very irritating but I’m maybe not the target audience.

united has free messaging on their flights and i found myself using meta's ai chatbot via whatsapp a few times. it's system prompt forces it to ask me inane questions at the end of every action so i would be happy to switch to something else.

just tried making one using this and it initially was way too casual for me and i didn't like how it split responses into many messages but it's very responsive to my prompts to change its style.

Having worked with mobile messaging and AI and trying to wrestle with iMessage and WhatsApp because I'm pretty sure this goes against ToS as they monitor how many new contacts and messages you're sending and get flagged to be shut down... If this is not the case, it would be very interesting....

This is the path forward, we need more protocols and systems to help integrate the future rather than more apps! Excited to try it out.

Surprised this got a second chance after hitting the front page almost a week ago; good luck!

Really nice landing page!

Does this use an official Apple API or...

SOB now i am going to be texted by some AI trying to scam me . Fantastic!

There are many things named flux. It’s not a big deal for one more, but maybe a more unique, descriptive name would differentiate.
