A text twin for consultants, coaches and founders
AI Digital Twin of Yourself That Answers From Everything You Wrote
Short answer: an AI digital twin of yourself is an assistant that has read your own documents and replies in the first person, the way you would. MentalClone builds one from the files you upload, such as reports, notes, transcripts and newsletters. It answers only from that material, and when your files do not cover a question it tells you instead of guessing.
Paste a page you wrote into the box and ask it something. Three questions, no account needed.

What your twin does with a question
You ask in plain English. The twin looks through your library for the passages that match, then writes the reply in your register, in the first person. A consultant asking "what did I tell the Denver client about pricing tiers?" gets the answer from the actual memo, not from what a generic chatbot thinks consultants usually say.
That is the difference that matters when you pay for one. A general AI is trained on the internet. A digital twin is useful only if it knows what you know and refuses to make up the rest.
- Answers come only from documents you uploaded.
- Replies in the first person, following the tone of your writing.
- Says plainly when your files do not cover the question.

Four kinds of AI twin and which one you are shopping for
"Digital twin of yourself" covers very different products. Pick by what you want copied: your face, your voice, your public persona or what you know.
| Kind of twin | What it copies | What you feed it | Who talks to it | Examples |
|---|---|---|---|---|
| Video avatar | Your face and voice reading a script | A few minutes of training video | Viewers of the videos you publish | HeyGen, Synthesia |
| Voice clone | How you sound | Audio recordings | Listeners of audio you generate | ElevenLabs |
| Audience clone | Your public persona, by chat and voice call | Content, podcasts, videos, social posts | Your audience, often as a lead magnet | Delphi, Coachvox |
| Knowledge twin | What you know and how you write it | Your documents, notes, transcripts and scans | You, plus anyone you send a private link | MentalClone |
If you were looking at audience clones, our Delphi AI alternative page compares Delphi's plans line by line, and the Coachvox alternative page covers the coaching version.
How to create an AI twin of yourself in an afternoon
-
1
Gather what you have written
Client reports, proposals, meeting transcripts, course material, newsletters, a book draft, years of notes. Quantity helps: the more of your thinking it can read, the more questions it can answer.
-
2
Upload it in one go
Drag in PDF, Word, Excel, CSV, RTF, Markdown, EPUB and saved email files, scans and phone photos of handwritten pages, or a zipped notes vault from Obsidian, Logseq, Bear or Notion. Each file can be up to 100 MB.
-
3
Test it with questions you get asked
Ask the questions clients, colleagues or readers bring you every week. Check that the answers sound like you and point to the right files.
-
4
Use it, and share it if you want
Draft from your own past work, or create a private link so a client can ask your twin between calls without an account.
Who pays for a digital twin of themselves
People whose value sits in years of writing that nobody, including them, can search quickly.
Consultants
Ask your own past engagements for the framework, the benchmark or the wording you used before, and hand a client a twin of the playbook you delivered.
Coaches
Clients ask your methods between sessions through a private link, and the answers stay inside what you actually teach.
Founders
New hires ask the twin how you think about pricing, hiring or positioning, using your memos and all-hands notes, instead of waiting for a slot on your calendar.
Authors and advisors
Find the example from chapter four or the 2022 newsletter in seconds, and draft new pieces in your own register.
How much does it cost to make an AI clone of yourself?
A knowledge twin on MentalClone costs $49 a month on Starter, or $288 a year, which is $24 a month. Professional, which reads three times more of your documents for each answer, is $99 a month or $588 a year. Both include unlimited documents and unlimited messages for you.
Audience clones cost more because they also sell the marketing layer. Delphi lists Builder at $79 a month and Scaler at $299 a month on annual billing, and Coachvox is one plan at $99 a month. Video avatar tools price by minutes of video rather than by documents.
The full breakdown is on the MentalClone pricing page.

When a knowledge twin is the wrong buy
MentalClone is a text twin built from documents. If one of these is the reason you are searching, a different kind of product fits better.
You want a talking video of yourself
MentalClone does not render a face. Use a video avatar tool.
You want your voice on calls
There is no voice calling. Audience clones and voice tools do that.
You want a public lead magnet
There is no website widget, lead form or paywall for visitors.
You have written very little
A twin can only answer from what exists. With a handful of pages it will say "I don't know" often.
Questions people ask before building a twin
Can I create an AI twin of myself?
+
Yes. Upload the documents you have written, such as reports, notes, transcripts and newsletters, and MentalClone builds a twin that answers questions from them in the first person. It needs real material to work from: the more of your own writing it can read, the more it can answer.
How do I create an AI twin of myself?
+
Gather what you have written, upload it as PDF, Word, Excel, text, EPUB, email files, scans or a zipped notes vault, then ask it the questions people usually bring you. Setup takes minutes; most of the time goes into choosing which files to include.

Will my digital twin make things up?
+
It is instructed to answer only from your documents. When your files do not cover a question, it says so instead of filling the gap with general knowledge, so a missing answer usually means a missing document.
Can other people talk to my AI twin?
+
Yes, on a paid plan. You create a private link and send it to a client or colleague. It opens in any browser without an account, the file list stays hidden, each link takes up to 100 questions a day, and you can revoke it at any time.
Is a digital twin of yourself the same as a video avatar?
+
No. A video avatar copies your face and voice to read a script. A knowledge twin copies what you know and how you write. MentalClone is a knowledge twin: text answers drawn from your own documents, without a face or voice.
What files can my twin learn from?
+
PDF, DOC, DOCX, XLSX, CSV, RTF, TXT, Markdown, EPUB and saved emails, scanned PDFs and photos of handwritten notes, plus zipped notes vaults from Obsidian, Logseq, Bear or Notion. Each upload can be up to 100 MB.
