You can build an AI that writes in your voice and knows your background, using the same tools from Parts 4 to 6. It cannot think for you, and it should never pretend to be you without people knowing.
What a "clone" really is
An AI version of you has three layers. The first two are easy to build. The third cannot be copied.
| Layer | What it means | Can AI copy it? |
|---|---|---|
| Voice | Your word choice, sentence length, humor, how you open and close a message | Yes, well, from enough samples |
| Knowledge | Your background, projects, opinions you have written down, people you work with | Yes, from files you give it |
| Judgment | What you would actually decide in a new situation, and why | No. It can guess from patterns, but the guess is not you. |
So the honest goal is not "a second me." It is "a helper that drafts like me and knows my context," with you making the final call.
The no-code way: a writing profile
This takes about an hour and works in any custom assistant from Part 4.
- Collect 10 to 20 samples of your writing. Emails, texts, posts, notes. Mix casual and formal. Remove other people's private details.
- You should have: one document of samples, each labeled ("email to a client," "text to a friend").
- Ask the AI to describe your style. Paste the samples into a chat and say: "Describe how this person writes: sentence length, tone, favorite phrases, how they start and end messages, what they never do. Be specific."
- You should get: a list of style rules. Correct anything that feels wrong.
- Write a short "about me." Your role, your main projects, what you care about, and words you use often. Half a page is plenty.
- Build the assistant. Create a new custom assistant. Put the style rules and "about me" in the instructions. Upload the samples as a file.
- Test it on real messages. Ask it to draft three messages you actually need to send. Compare with what you would write.
- You should see: drafts that need light edits, not rewrites. If not, add the missing rule and test again.
- Keep teaching it. Each time you edit a draft, note what you changed and add it to the rules.
Going further
Memory features. Several chat apps can now remember facts about you across conversations. This builds your "knowledge" layer automatically as you use it. Check your settings to see, edit, or delete what has been saved, and turn it off if you prefer.
Fine-tuning on your own writing. If you have thousands of your own messages, a developer can fine-tune a model on them (see Part 6). The result captures your voice more deeply than instructions can. The trade-offs:
- It takes real effort to collect, clean, and format the messages.
- Your messages contain other people's words and private details. These must be removed first.
- It still learns patterns, not judgment. It will confidently write things you would never say.
For most people, a well-built writing profile gets close enough, at a fraction of the effort.
Personality frameworks. You can also give the AI a description of how you tend to think and react, using a framework it already knows: a behavioral model, an MBTI type, your astrology chart, or your Chinese BaZi (Four Pillars) chart. These give it a shared vocabulary for your tendencies: "I'm an INTJ," or "I'm a Yang Fire day master." Combined with fine-tuning on what you have actually said in certain situations, the result can feel remarkably close to you.
One honest note: MBTI has limited support in psychology research, and astrology and BaZi are traditions, not science. Use them as a language for describing yourself, not as proof of who you are. The real signal still comes from your own words and choices.
Why I chose a different direction
I combined these methods, behavioral frameworks plus fine-tuning on how I respond in different situations, and found a way to make a clone that was eerily accurate at copying my responses. But I decided not to take it further. I didn't want to trade my conscience for money.
Two things stopped me:
- Clones create attachment. A copy of a person, or of someone you love, is easy to cling to. I don't think holding on to copies is a healthy direction for people.
- A clone is a manual for manipulation. To copy someone's behavior, you have to map their strengths and weaknesses. Anyone holding that map knows exactly which buttons to push.
A clone uses what it knows about you to keep you the same. Raya uses it to help you get out of the loops, and then gets out of your way.
So I built Raya.ai to do the opposite. Instead of copying you as you are, Raya imprints the clearest, most efficient, and most positive version of you. Some call it your best self or your higher self. That version lives in an agent that does things for you the way you would do them, at the highest standard, with AI's strengths built in, and explains its work back to you in a way you can understand.
The goal is not a second you. It is to free you from living to work and working to live, and from being boxed in by what someone else wants. Raya aims to give you room to choose your own path, beyond the pressures of money, status, and safety.
Ground rules
- You send it, you own it. Read every draft before it goes out under your name.
- Don't pass it off as you in real time. Letting an AI chat with people as you, without them knowing, breaks trust. Use it to draft, then send it yourself.
- Only clone yourself. Building an AI of someone else's voice or face without their permission can hurt them and, in many places, may break the law.
- Protect other people. Your messages are full of friends', family's, and coworkers' details. Strip them out before uploading anything.
- Know where it lives. A file of your writing plus your "about me" is a detailed portrait of you. Keep it on a platform you trust, and delete it when you stop using it.
The tools will keep changing. The habits from this series, clear asks, good context, checking the answer, and keeping your own judgment, will carry over to whatever comes next. And remember the idea from Part 0: let AI execute, so you can create. Part 8 shows how to put all of this to work on something you care about.
