The short answer: Delphi is the strongest choice for coaches and experts selling access to their knowledge, and it charges accordingly: subscriptions start around $29/month and climb steeply. If you’re a creator who wants a twin that earns rather than costs, or you publish outside English, the alternatives below fit better.
Here’s the honest map of the space in 2026.
What Delphi does well (credit where due)
Delphi built the category’s reference product: “digital minds” trained on your content that your audience can talk to. The roster skews expert (coaches, doctors, authors) and the pitch is scaling your insight without burning out. Fidelity is taken seriously, and the product is polished.
The structural limits, from a creator’s perspective:
- You pay up front. Tiers run roughly $29 to $399+/month (pricing), so the twin is a cost center until you build your own monetization on top.
- No commerce layer. Delphi monetizes access to knowledge (subscriptions, bookings). If your audience mostly asks “what should I buy?”, there’s no affiliate engine to catch that intent.
- English-first. Creators publishing in smaller European languages are not the target.
The alternatives, honestly compared
Rylies: the commerce-native twin (disclosure: that’s us)
Rylies builds your twin from your public videos and monetizes it with your affiliate links: fans ask what to buy, the twin answers with your real verdicts, the link is attached automatically, and from the Creator tier up you keep 100% of your commissions. It’s free to start; the model only works if it earns. Guardrails are enforced in code (crisis-safe responses, kill switch), and it’s proven on hard languages first (Slovak), not English-only. Best for: creators whose audiences ask buying questions (tech, fitness, fashion) and creators outside the English-speaking core. Not for: selling consulting hours or paywalled courses (Delphi’s home turf).
Meta AI Studio: free, but you’re the product
Meta AI Studio lets you build “an AI extension of yourself” inside Instagram, Messenger and WhatsApp, free, with real distribution. The catch: it’s a form-configured persona, not a corpus-grounded twin; it earns you nothing (no affiliate or subscription layer); and the conversations happen on Meta’s surfaces, feeding Meta’s data advantage, not yours. Best for: trying the concept with zero commitment. Not for: income, fidelity, or owning your audience relationship.
Kamoto.AI: the character marketplace
Kamoto.AI approaches it as a marketplace: create and train an “AI character” and rent it out per usage. Configuration is manual rather than ingested from your content catalog, and there’s no affiliate commerce engine. Best for: experimenting with licensed AI personas. Not for: creators who want the twin to feel indistinguishably like them.
The adult lane: OhChat and OnlyFans-style twins
OhChat proved fans will pay serious money to chat with digital twins (creators keep 80% there too). But the platform lives in the adult/parasocial space, so if you’re a mainstream creator with brand partnerships, it’s the wrong neighborhood for your name. Best for: that specific market. Not for: brand-safe creator businesses.
Video-clone tools: HeyGen, Tavus &co.
These make an avatar that looks and sounds like you for videos and calls, a different product answering a different question. No knowledge grounding, no fan chat at scale, no commerce. Useful alongside a twin, not instead of one.
How to choose
| If you… | Choose |
|---|---|
| Sell expertise (coaching, courses) to an English-speaking audience | Delphi |
| Get asked “what should I buy?” ten times a day | Rylies |
| Want a free experiment inside Instagram | Meta AI Studio |
| Want to license an AI character per use | Kamoto |
| Need a talking-head video avatar | HeyGen / Tavus |
The test that matters more than any feature table: ask each product what happens when the AI doesn’t know your opinion on something. If the answer isn’t “it says so and defers to you,” the twin will eventually say something you never said, to a fan who trusts you.
Rylies builds preview twins from public content, so you can judge the fidelity before you commit to anything. Join the waitlist and meet yours.
