Inborn runs on your device, so there is nothing to sign up for and nothing to connect. Pick the platform you are on. The purchase is one time, in the store you already use, and it is the same app whichever store sells it to you.
iPhone and Android
Neither store listing is public yet; both links open the real product page the moment it is. The Instant model, 533 MB, arrives with the app, so the first chat works before anything else downloads.
In a browser, with no install
The browser version is free and stays free. Your browser downloads the model once, 533 MB, into its own storage, and then answers with no network at all. Pro and Work are sold in the apps, not in the browser.
Windows and macOS
There is no Windows or macOS build to download today, and we would rather say so than publish a link that does nothing. The browser version above runs on both in the meantime, and it is the same engine.
Build it yourself
The source is public at github.com/moshecohen90/inborn, source-available under the existing license: read it, build it, publish what you find. None of the checks on the Proof page depend on reading it, which is the point of them.
If something goes wrong
Refunds go through the store that charged you, not through us. Everything else, including a purchase that will not restore, is on the Support page, which is an email to a person.
