How Much Does an AI Twin Cost? A Straight Answer on 2026 Pricing
August 14, 2026 · 7 min read · by the hiy team
The short answer
An AI twin costs anywhere from $0 to seven figures, and where you land depends entirely on which of three products you're being quoted for. A knowledge twin — a page that answers your audience from your own material — runs from $0 to roughly $300 a month at creator scale. A video or voice avatar twin is usually a low monthly subscription with rendered minutes metered on top. An industrial digital twin is not a plan you pick; it's an engineering engagement you get quoted for.
Disclosure before anything else: we make hiy, which is one of the products priced further down, and it has no voice feature and none of Delphi's scale. Read accordingly. Every figure below is either checkable on a public page or explicitly hedged, and where we don't know a number we say so rather than round one up.
Why the same three words carry three prices
Three unrelated industries adopted overlapping vocabulary within about a decade of each other, and search engines have been collapsing them ever since. If you type "how much does an AI twin cost" you will get results from a factory simulation vendor, a talking-head video tool, and a creator chatbot, all answering a different question.
The distinctions themselves are worth twenty seconds — we wrote them up in digital twin vs AI twin vs persona and won't re-explain them here. What that post doesn't do is price them. This one does.
| What you're buying | How it's priced | Rough cost | |
|---|---|---|---|
| Industrial digital twin | A live simulation of a machine, plant or grid | Quoted engagement: sensors, integration, modelling | Five to seven figures; no public price page |
| Avatar twin | Video or audio of your likeness reading a script | Subscription plus metered rendering | Tens of dollars a month, minutes on top |
| Knowledge twin | A page that answers your audience in your voice, from your material | Flat monthly fee per creator | $0 to about $300 a month |
What does an industrial digital twin cost?
There is no price page, which is the answer. These are bespoke engagements: instrumenting physical assets, building a simulation model, and running a telemetry pipeline against it forever. The cost is dominated by integration labour and sensor infrastructure, not software licences, so it's quoted like consulting — commonly five to seven figures, occasionally more, and never listed publicly.
If you arrived here from manufacturing, energy or clinical modelling, stop reading. Nothing else on this page is priced anywhere near your problem.
What does a video or voice avatar twin cost?
Roughly the price of a design tool subscription, plus a meter. The avatar platforms — the ones that generate a video of your likeness speaking a script you type — charge a monthly fee and then ration output by the rendered minute, because GPU video generation is genuinely expensive per second produced.
Entry tiers in this category are tens of dollars a month as of writing, with minute allowances on top. We're not going to quote you a tighter range than that, because every vendor here publishes its own page and re-prices often. Open theirs before you budget.
The thing to notice is what the meter implies. You pay by how much you publish. It scales with your output, not your audience, which makes it a production tool rather than an always-on presence. Nobody is having a conversation with an avatar twin at 2am.
How much does an AI twin cost when it's a knowledge twin?
Between free and about $300 a month, and the ladder is unusually visible in this category because most vendors publish it.
The clearest public reference point is Delphi. As of August 2026, on delphi.ai/pricing, the tiers are Free at $0, Builder at $79 a month, Scaler at $299 a month, and Immortal at custom pricing. Builder includes voice calling, several million training words, contact collection and analytics. That is a real ladder for a real product and we won't pretend otherwise.
One warning that matters more than any single number: third-party comparison sites currently list Delphi at $99 and $399, and elsewhere at $97. Those figures contradict the vendor's own page. When you're researching a purchase, the aggregator is not a source — the vendor's pricing page is. That applies to this page too.
Elsewhere in the category the model changes shape. Support-desk products like Chatbase price by message credits, which means your bill moves with conversation volume. Coach-focused clone products go the other way: Coachvox advertises a single plan at $83/month billed annually, as of 14 August 2026, with a 14-day trial and no free tier. One flat number, no tier maths — which is cheaper than a ladder if you are small and dearer if you never grow.
The lesson across all three shapes is the same. A monthly figure means nothing until you know what moves it: messages, audience size, or nothing at all.
What does hiy cost?
Two plans, and one of them is free.
- Free — includes a real, published twin at hiy.ai/yourname. Not a trial page, not a watermarked demo. Your visitors always chat free, on every plan, forever. You are never charged for someone asking your twin a question.
- Founding Creator — $49 a month — the paid tier, and it is not switched on yet, so read that as a stated price rather than a checkout you can complete today (more on that below). It's a founding rate that stays yours; list price is intended to rise toward $79 once we have outcome proof to justify it. The 14-day trial is card-free and the clock starts when your twin goes live, not when you sign up, so the evening you spend wiring up sources is never trial time.
The paid promise is narrow and we'd rather state it narrowly: leads and bookings. Founding Creator is for people who want the twin working as a front door — capturing details, routing people to your existing Cal.com or Calendly link, showing up unbranded. The full breakdown lives on the pricing page.
What the $49 does not buy
It does not buy honesty. That's the part worth being explicit about, because trust features are so often sold as the upgrade.
Paying removes the "Powered by hiy.ai" credit and swaps the brand noun for the category noun, so it reads "Sam's AI twin" instead. That's the whole cosmetic difference. What money cannot remove, on any plan, at any price:
- Citations on grounded answers. Open one and you get the whole passage, and a link back to the spot on your original page.
- The honest "I don't know." Outside your material, the twin says so — in your tone — and shows the searches it ran before giving up.
- The AI disclosure label on every twin.
- The report link on every public twin.
- The Verified badge, when the identity check has cleared.
The price buys reach and leads. It does not buy the right to look more certain than the material supports. We think a plan that could sell you that would be a worse product, not a more premium one.
Keeping the free credit isn't a penalty either. The credit link carries your referral, and anyone who follows it and signs up is recorded as yours.
The honest version
Three things you should know before you budget for any of this.
Our paid plan is not switched on. Checkout, billing portal and webhooks are built, and they are inert until a real price exists on our side. So the $49 above is a stated price for a stated plan, not a live purchase you can complete today. What you can do today is publish a twin free. We'd rather tell you that than let you find out at a payment form.
hiy has no voice. Delphi does. If a spoken twin is the thing you actually want, we are the wrong product and $79 there beats $49 here without argument. We also don't have their scale or their roster of famous names.
A cheaper twin that misrepresents you costs more than the difference. The only sensible way to compare at this price range is to publish one, ask it the six questions your audience actually asks, and see whether it cites, hedges, or bluffs. Every product in this category will answer those questions. They differ in what they do when they shouldn't.
Which one you actually need
If you're modelling a physical asset, you need an engineering vendor and a procurement process. If you need to produce video at volume without filming, you need an avatar platform and a rendering budget. If you need the same handful of questions answered, over and over, without you in the room — that's a knowledge twin, and the honest budget is $0 to try, under $100 a month for most creators, and about $300 at the top of the published ladders.
Start by pricing your own problem rather than the software: the repeat questions calculator works out what the same six answers are already costing you in hours. If the number is small, don't buy anything. If it isn't, build a twin free and read it back before you consider any plan.
