AI TWIN
Write its personality (or let Inkling draft one from your journal — you approve every word), teach it what it's allowed to share, and put it on your site or link-in-bio.
Start your twin with Bonfire01
A persona profile in your voice: who you are, what you love, what it may talk about. Stuck? Inkling can draft one from your journal — transiently, and you review every word before anything is saved.
02
The studio preview runs the exact pipeline strangers get — privacy filter included — so what you see is what they see.
03
One switch. A shareable page at twin.usehearth.ink/@you, and an embed snippet for your site. Flip it off and everything goes dark, instantly.
04
Domain locking, per-visitor rate limits, a daily budget, a privacy filter on by default, and a permanent “AI twin” badge visitors always see.
The whole point
Your twin reads its persona profile and the documents you upload — nothing else. Your journal stays sealed unless you explicitly, separately opt into live grounding (off by default, heavily fenced, instantly reversible). We never blur that line.

data-hearth-key="pk_…" async></script>No. The twin speaks only from material you published to it. The optional live-grounding mode is a separate consent with its own warnings — and even then a privacy filter redacts identifier-shaped things, and Private Vault accounts are structurally excluded.
Always. Every twin surface carries a permanent “AI twin — an automated chatbot, not the real person” notice, and the twin says so itself if asked.
Your Bonfire plan funds a daily token budget you control. When it's spent, your twin politely rests until tomorrow — no surprise bills, ever.
