Software for the internet I want to live in.

For people who organize meetups, conferences, hackathons, and communities that keep going between them.

At most gatherings you meet whoever happens to stand next to you at the coffee break. In Nostrautica, members introduce themselves however they like: with their Nostr profile, a short video, a voice note or a few lines of text. An AI coordinator reads those intros along with what each person has already posted on Nostr, then tells everyone who they should meet and why, matching shared interests as well as skills that complement each other. Everything is encrypted to the event's key and stored on Nostr relays.

For people who spread ideas through many channels of their own.

You finish a project, write an article or get an idea, and the question is who should hear about it. Your channels might be a newsletter, a Signal group, your course students or the sauna club, anywhere information spreads from you. Describe what each channel cares about, and Lievik scores everything you publish on Nostr or your blog against every one of them, and remembers what each channel already got. It's marketing where you do the targeting yourself, and AI helps you write the message.

For people who want a separate identity for each of their projects.

A new npub starts with zero followers, so Emanator can boost its posts from your main identity automatically, after a random delay. You write and schedule posts for all your accounts in one place, with AI drafting that follows each account's voice. One view collects the replies and comments across every account so you can answer them, and another holds the private messages for all of them. You sign posts ahead of time on your phone with Amber, and the server stores only finished, signed posts until their time comes.

For people who follow more people on Nostr than they can keep up with.

Nalgorithm reads the posts from the people you follow, picks the ones that match what you care about, and turns them into a short spoken digest you can play in the browser or save as an MP3. You describe your interests in plain words ("Bitcoin, cats, long thoughtful posts, not price talk"), and it also learns from the posts you like in your usual client. The ranked feed is there too when you'd rather read. It runs in your browser and only reads, so it can't post as you.

For anyone who wants a personal page without renting hosting or renewing a domain.

Your site is a single HTML file stored on Nostr. Sign in with your key, click into the page and type; it saves and republishes itself, and anyone who opens it sees the new version. The templates, the editor and publishing are free. If you want AI to write or rework the page, pay for it in Lightning or bring your own API key.

For people who keep their sats on Lightning and get handed a QR code for something else.

Someone wants USDT on Arbitrum, or Monero, and all you have is a Lightning wallet. Scan their code with AnyPay and pay a Lightning invoice; it swaps in the background and delivers USDT or USDC on Ethereum, Arbitrum, Polygon, Base or Optimism, or XMR, LTC, DOGE, ZEC, SOL or on-chain BTC. Add it to your home screen and it works like a native app.

For small merchants who want to accept Bitcoin over Lightning.

Payment processors ask for KYC and can freeze your funds, and running your own BTCPay Server means a VPS and ongoing maintenance. CashuPayServer speaks the BTCPay API but runs on ordinary shared hosting: if your host can run WordPress, it can run this. WooCommerce and other BTCPay plugins work after you change one URL. A Cashu mint handles the Lightning side and holds your funds until you withdraw them, or you can have them forwarded automatically to your Lightning address. It's experimental, don't be reckless.
