Three Kinds of AI Twin
Decide which one you want before you compare prices.
A knowledge twin. Trained on what you know: your courses, frameworks and transcripts. People ask it questions and get your answers. Personify, Delphi, MyClone, CoachVox and BuddyPro sit here.
A video twin. It copies how you look and sound, then reads any script you give it. It does not know anything you have not written for it. HeyGen is the best known.
A live video twin. A face that holds a real-time conversation on a video call. Tavus builds these, mostly for developers.
If your clients keep asking you the same questions, you want a knowledge twin. One naming trap: search for "digital twin app" and most results are industrial software for factories and buildings. For the definitions, see what is an AI twin and AI twin vs digital twin.
Our pick for coaches and experts
1. Personify
The AI twin built for people who sell their expertise.
Personify turns what you know into a clone your clients can talk to at any hour. You upload your PDFs, videos, course material and coaching frameworks, set its tone and branding, then share it as a link or embed it inside Kajabi, Thinkific, Teachable or Circle with single sign-on.
Most twins on this list are built for fans, for video or for developers. Personify is built for the working coach: the twin answers the questions you answer every week, between sessions and after hours, so you stop being the bottleneck.
Trained on your material. Your frameworks and course content, not the open internet, so answers follow your method.
Lives where clients already are. Inside your course or community, or on a shareable link, with one line of code to embed.
The lowest price for a knowledge twin here. A free tier, then Pro at $39 a month or $29 a month billed annually.
Connected to your stack. Answers in 100+ languages, and sends leads and conversations to 9,000+ apps through Zapier on every plan.
- Who it fits
- Coaches, course creators and experts who want clients answered from their own material.
- Price (Oct 2026)
- Free tier. Pro $39/month, or $29/month billed annually.
- Good to know
- Self-serve clones are text. A twin in your own voice comes with Done-For-You, built in about 14 days.
2. Delphi
Best for public figures with a large audience.
Delphi builds a "Digital Mind" you can chat with or call by voice, trained on your writing, YouTube and podcasts. It answers in 40+ languages. Its top tier, Immortal, adds SMS, WhatsApp, an API and single sign-on, and is aimed at public figures.
For a closer look, see Delphi alternatives and Delphi vs CoachVox.
- Who it fits
- Creators and leaders with a big audience, up to celebrities on its top tier.

- Free tier. Builder $79/month and Scaler $299/month, billed annually. Immortal is custom priced.

3. MyClone
Best for service businesses that screen prospects.
MyClone builds a chat and voice clone of your expertise and positions it to screen prospects before a call. Pro includes 30 personas, 3 voice clones, white-labelling, and Stripe and HubSpot connections.

4. HeyGen
Best video twin of your face.
HeyGen asks you to record one short video, then clones you into an avatar that looks, moves and gestures like you. Paid plans add voice cloning and 175+ languages. It is the strongest option on this list for video, and the wrong one if you want clients to chat with your knowledge.
- Who it fits
- Creators and marketers who want videos of themselves without filming each one.
- Price (Oct 2026)
- Free tier (3 videos a month). Creator $29/month, or $24/month billed annually. Pro from $49/month.
- Watch out for
- It reads scripts. It is not a twin people can ask questions.
5. Tavus
Best for live, two-way video conversations.
Tavus makes lifelike video agents that see, hear and respond on a call. Developers get custom faces and an API; individuals get "PALs" on its consumer plans. Its pricing page still showed an older table beside the current one when we checked, so confirm the plan before you buy.
- Who it fits
- Developers and companies building real-time video agents, plus individuals on its consumer plans.
- Price (Oct 2026)
- Free tier. Developer Starter $22/month (60 minutes, 1 custom face). Consumer Plus $20/month.
- Watch out for
- It is priced by the minute, and the developer plans assume you are building an app.
6. CoachVox AI
A coach-focused chat twin.
CoachVox AI builds a chat version of a coach from their content and methods, with unlimited chats and 50+ languages. We compare it in detail in Personify vs CoachVox AI and CoachVox alternatives.
- Who it fits
- Coaches, consultants and expert founders who want one plan with no tiers.
- Price (Oct 2026)
- $83/month billed annually. 14-day trial.
- Watch out for
- There is no free plan, and the trial asks for a card.
7. BuddyPro
For experts selling a premium subscription.
BuddyPro builds a white-labelled twin of an expert that the expert sells to their own clients. The prices on its site, from $797 to $3,497 a year, are what an expert might charge clients, not what BuddyPro costs. More in BuddyPro alternatives.
- Who it fits
- Established experts who want to sell their twin to clients as a yearly subscription.
- Price (Oct 2026)
- Not published. Its site mentions a yearly platform fee and AI costs of about $300 per user per year.
- Watch out for
- Clients use it on Telegram or BuddyPro's own app, and pricing is only shared on a call.

How To Choose
Four questions decide most of it.
Should it know things, or look like you? A knowledge twin answers questions. A video twin reads scripts. Very few do both well.
Who will talk to it? Paying clients, fans and prospects want different things. Pick the app built for your audience.
What will it cost at your size? Flat plans, credits and per-minute pricing behave differently as usage grows. Model it at the volume you expect.
Can you test it first? Five of the seven have a free plan. Personify can preview a clone from your website in about 30 seconds, with no signup.
Frequently Asked Questions
What is the best AI twin app?+
For coaches, course creators and experts who want a twin that answers clients from their own material, Personify is our pick: a free tier, Pro at $39 a month or $29 a month billed annually, and it sits inside Kajabi, Thinkific, Teachable or Circle. For a video twin of your face, HeyGen. For live video conversations, Tavus.
What is an AI twin?+
An AI twin is a digital version of you, trained on your words, knowledge or likeness, that can talk to people when you are not there. Some twins are text chats, some speak in your voice, and some are video avatars of your face.
Can I make a digital twin of myself for free?+
Yes. In October 2026, Personify, Delphi, MyClone, HeyGen and Tavus all showed a free plan. The free plans differ a lot: HeyGen allows 3 short videos a month and MyClone 500 text messages, for example. CoachVox AI offers a 14-day trial with a card instead.
What is the cheapest AI twin for coaches?+
Of the knowledge twins on this list, Personify has the lowest paid price: Pro is $39 a month, or $29 a month billed annually, with a free tier to start. Delphi Builder and MyClone Pro are $79 a month, and CoachVox AI is $83 a month billed annually.
What is the difference between an AI twin and a digital twin?+
A digital twin was originally an engineering term for a live model of a machine, factory or city. An AI twin, or a digital twin of yourself, is a model of a person. Search for "digital twin app" and you will mostly find industrial software, which is why this list is about people.
Do AI twin apps clone your voice?+
Some do. Delphi, MyClone and HeyGen include voice. Personify self-serve clones are text clones, and voice cloning is part of Personify Done-For-You, which is scoped on a discovery call.
Does an AI twin replace a coach or therapist?+
No. A twin answers questions from your material at hours you are not working. It does not replace a qualified coach, therapist or advisor, and it should be set up and described to clients that way.
