Short answer: Delphi AI pricing starts with a free plan for your first Digital Mind. Builder costs $79 a month and Scaler $299 a month on annual billing, which is $948 and $3,588 a year. Immortal, for public figures, has custom pricing. Paying month to month costs more, because Delphi advertises savings of up to 20% on annual plans.

Delphi sells an AI clone of you, which it calls a Digital Mind, that talks to your audience by chat and voice call. The price you pay is set mostly by two things: how many words of your content it can train on, and how many places you want to embed it. The numbers below come from Delphi's own pricing page, which now lives at delphi.co after the move from delphi.ai. Where the public page and what buyers report at checkout disagree, we say so.
Delphi AI pricing for every plan
| Free | Builder | Scaler | Immortal | |
|---|---|---|---|---|
| Price on annual billing | $0 | $79 a month | $299 a month | Custom |
| Yearly cost | $0 | $948 | $3,588 | Quoted by Delphi |
| Training words | Entry allowance | 5 million | 12 million | Unlimited on white-glove setup |
| Chat and voice calling | Yes | Yes | Pro voice calling | Yes |
| Embedding locations | None listed | 2 | 10 | Custom |
| Integrations | None listed | Slack, custom alerts, product recommendations | Plus contact import, custom workflows, custom branding | Plus SMS, WhatsApp, API access, single sign-on |
| Built for | Trying a first Digital Mind | Professionals and creators | Leaders with growing audiences | Celebrities and public figures |
Delphi's page labels Scaler as its most popular plan. Every paid tier includes everything in the tier below it, so the jump from Builder to Scaler buys more training words, better voice, more places to embed the clone and tools for importing and working with contacts.
How much does Delphi cost per month if you do not pay yearly?
More than the headline price. The $79 and $299 figures are shown with the pricing toggle on annual billing, and Delphi says annual plans save up to 20%. Reviewers who went through checkout on monthly billing have reported Builder at $99 a month and Scaler anywhere from $349 to $399 a month. Delphi does not print a monthly figure on the public page, so confirm the number on the checkout screen before you budget, and assume monthly billing costs roughly a fifth more than annual.
What one year of Delphi really costs
For most buyers the real decision is a yearly commitment, so it helps to look at the whole year rather than the monthly sticker.
- Builder, annual: $948 a year, paid up front.
- Builder, monthly: about $1,188 a year if the reported $99 monthly rate applies to you.
- Scaler, annual: $3,588 a year.
- Scaler, monthly: roughly $4,188 to $4,788 a year at the reported $349 to $399 rates.
If you are a solo consultant or coach, Builder is where the comparison usually happens. Scaler only pays for itself when the clone is part of how you sell to a large audience: ten embed locations, contact import and custom branding are marketing features.
Is Delphi AI free?
Partly. Delphi has a free plan that lets you build your first Digital Mind with chat and voice calling. It is enough to see how the clone sounds, but the training word allowance is small and there are no embedding locations, integrations or contact tools. Anyone using the clone with real clients or an audience ends up on Builder or higher.
What you are paying for on Delphi
Delphi's price makes sense once you see it as an audience product. You train a clone on your public content, such as podcasts, videos, talks, posts and documents, and put it in front of the people who follow you. It answers them by chat or by phone-style voice call, can recommend your products, sends you alerts about conversations and, on Scaler, imports contacts and runs workflows. The training word limits matter because public content is large: a few years of podcasts can run into millions of words.
That is a different job from the one many people have in mind when they search for an AI clone of themselves. If what you actually want is to ask your own past work questions, or to let a few clients ask it between sessions, you do not need voice calls, embeds or contact import, and you are paying for them anyway.
Delphi pricing compared with other AI clones

| Coachvox AI | $99 a month, or $83 billed yearly | $996 | A coaching clone with lead capture and paid access |
| ChatGPT Plus with a custom GPT | $20 a month | $240 | A quick clone from instructions and up to 20 files |
| MentalClone Starter | $49 a month, or $24 billed yearly | $288 | A private twin that answers only from your own documents |

Is Delphi AI worth the price?
Yes, if the clone is a sales channel. A coach, author or creator with a real audience who wants an always-on version of themselves on a website, answering by voice and collecting contacts, gets those features in one product, and $948 a year is modest next to one extra client. Delphi is also the stronger pick if most of your material is audio and video rather than documents.
It is less worth it if the clone is mainly for you. Consultants, founders and advisors who want to search years of reports, memos and transcripts, and get answers in their own voice, pay for a marketing layer they never switch on. In that case a private AI digital twin of yourself built from your documents does the job for a fraction of the cost. If you also want visitors who find you online to be screened and booked before a call, that is a separate job better handled by a tool that runs the discovery consultation and client intake for you.
How MentalClone differs, and what it costs
MentalClone builds a twin from what you have written. You upload PDF, Word, Excel, CSV, RTF, Markdown, EPUB and saved email files, scans and phone photos of handwritten notes, or a zipped notes vault, up to 100 MB per file. It answers in the first person in the tone of your writing, only from those files, and when they do not cover the question it says so rather than inventing an opinion you never wrote down.
- Starter: $49 a month, or $288 a year.
- Professional: $99 a month, or $588 a year, reading three times more of your documents for each answer.
- Unlimited documents and unlimited messages for you on both plans.
- Private links let a client ask your twin in a browser with no account, up to 100 questions a day per link, revocable at any time.
What it does not have, so you can rule it out quickly: no voice calling, no video avatar, no website embed and no paywall for visitors. Full details are on the MentalClone pricing page, and the demo at the top of this page answers three questions from text you paste in, with no account.
