Stepping outside of the hardcore bitcoin/nostr bubble, 90% of the time people ask me if I am talking about a new shitcoin when I mention Sats.
Then I take a step back and remember most bitcoiners have never even got to make their firts transaction out of their stack.

It is my custom backend with OpenRouter. But I have been looking at the routstr proxy implementation and we developed ~80% the same backend. I'll be integrating mine to their spec and contribute to that protocol soon 🥜🤝⚡

Good catch!
I've been thinking about how a small llm could be running locally on the browser (or native app) and screen your prompt for personal information and just changing it to not leak it to the provider, but this is more like a band-aid.

It is Open Source 🚀! I'll be updating the documentation with more technical details soon, but basically
- NIP-60 Handles payments
- Each chat interaction is a nostr event that is encrypted with your private key and published to Nostr relays so you can sync the app across many devices. You only need a browser 🤙
- Nostr only exist on the client to handle everything.
- The server never learns anything about you (not even your npub) since it only cares that each request has enough ecash to process the each prompt. 🤝

If no wallet event was found from relays, it creates and publishes a new kind:17375 wallet event.
I think it is requesting the wallet event before getting your relay list configuration and asking your relays

Hi! You should give https://cypherflow.ai a try!

I suggest you try cypherflow creating a brand new key pair in the app (just select create new account).
Even if the activity is not traceable to your account, this is still an experimental app so I dont suggest playing around in it with your main nostr key pair ⚡

2025-07-20 02:07:32 UTC

- reply

Great question!
Short answer, No.
Your nostr keys are used to encrypt the questions you have made and the answers you have received and backed them up on nostr directly from your device. You never reveal your nostr identity or any other personal infomation while using cypherflow.
So cypherflow never knows who is using it, and all of the user chats are just encrypted gibirish in nostr relays. Only the corresponging knows about then and only them can see them.

I developed my own backend for this service.
The client side app is already opensource and I'll be doing the same for the backend soon ⚡

I have also been using @nprofile…qus8 for a while, and has been a great inspiration.
Cypherflows user experience is not as smooth and polished... yet ⚡⚡⚡⚡⚡⚡
Any feedback is welcomed

Thanks for checking it out!
You are right, currently the chats are being deleted only locally but they are backed in nostr relays as encrypted notes.
So you may delete it, but once you refresh that info is pulled down again to your device.
⚡Actual chat deletion coming soon⚡
