Nenrin in one paragraph
Nenrin is a private web app where you tell your life story, by voice or by typing, to an AI guide named Kiko. Kiko asks good questions and writes down what you say in your own words. What builds up is a record you own: a lifeline of the moments that mattered, life chapters, a Life Log, the people in your life, your values, and a North Star. If you are in therapy, you can choose to share parts of it with your therapist, who can read what you share. Kiko never gives advice, never diagnoses, never interprets you, and never scores you; every number in your record is one you chose. Nenrin is not therapy and is not for crisis.
Facts
| Name | Nenrin (年輪, Japanese for tree rings). Pronounced nen-rin. Tagline: "Your life, one ring at a time." |
|---|---|
| What it is | A private web app for telling your life story to an AI guide (Kiko) that asks questions and records your answers in your own words. |
| What it is not | Not therapy. Not a therapist, counselor, or substitute for one. Not a medical device. Not a crisis service. Not monitored. Not a journal with prompts, not a habit or goal app. |
| Who it is for | Adults (18+) who want more insight into themselves by seeing their own story in one place, and adults currently in therapy who want to bring more of their story into sessions. Therapists take part only as free, read-only readers whom the person invites. |
| What the record holds | A lifeline (moments rated by the person from -5 to +5), life chapters, a Life Log, a people map, values, a Wheel of Life, a North Star, insights, pre-session summaries, and optional tools (Enneagram self-report, Johari Window, self-entered test results, action plan). |
| What Kiko never does | Give advice, opinions, diagnoses, interpretations, labels, or ratings. Every number is supplied by the person. Kiko never takes instructions from a therapist. Kiko is AI and says so. |
| Sharing | Nothing is shared by default. The person chooses what a connected therapist can read, category by category, can revoke at any time, and can see when the therapist last looked. The therapist's view is read-only on screen, with no download or export. |
| Ownership and privacy | The person owns the account, can export everything (Markdown and JSON), and can delete everything at any time. No ads, no analytics or tracking cookies, no sale of data, nothing used to train any model. Processors: Cloudflare (hosting, database, speech-to-text), Anthropic (Kiko's replies), Cartesia (spoken voice when voice mode is on), Google (sign-in). Data is stored in the United States. Voice audio is transcribed and discarded. |
| Crisis | Nenrin is not therapy and is not monitored. If you are in crisis, call or text 988 in the US, or your local emergency number. If Kiko hears something worrying it shows one fixed card with crisis resources and notifies no one. |
| Availability | Invite-only as of October 23, 2026. People join a waitlist at https://nenrin.ai. The app will live at https://app.nenrin.ai. |
| Pricing at launch | $19 per month or $149 per year (USD), one plan, 14-day free trial. Therapist seats are free. Nenrin never bills practices. Billing happens inside the app through Stripe. |
| Platform | Web app, works in a browser on phone, tablet, or computer. Light and dark modes. Sign in with Google. |
| Maker | Blair Williams (https://blairwilliams.com), a software founder who built it for his own therapy first. A new company will be formed to operate it. |

Questions and answers
What is Nenrin?
Nenrin is a private web app where you tell your life story, by voice or by typing, to an AI guide named Kiko. Kiko asks good questions and writes down what you say in your own words. What builds up is a record you own: a lifeline of the moments that mattered, life chapters, a Life Log, the people in your life, your values, and a North Star. If you are in therapy, you can choose to share parts of it with your therapist, who can read what you share. Kiko never gives advice, never diagnoses, never interprets you, and never scores you; every number in your record is one you chose. Nenrin is not therapy and is not for crisis.
Is Nenrin therapy?
No. Nenrin is not therapy, and Kiko is not a therapist. It is a place to tell your story and keep the record. Many people use it alongside a therapist; some use it on their own. Your therapist, if you have one, does the therapy.
Who is Kiko?
Kiko is the AI guide inside Nenrin. Kiko asks specific questions about your life, reflects your words back so you can check them, and files what you say into your record. Kiko is AI and says so. Kiko never gives advice, opinions, diagnoses, interpretations, or ratings.
Does Nenrin analyze me or tell me what my story means?
No. Nenrin records; it does not analyze. The insight people get from Nenrin comes from seeing their own story laid out in one place, in their own words, not from the software reading them. If you want an interpretation, that is a conversation for you and your therapist.
Where do the numbers in my record come from?
From you. Each moment on your lifeline carries a rating from minus five to plus five that you chose. Kiko may ask whether a moment sounded like a certain strength; that estimate is shown as a hollow, dashed mark and counts for nothing until you keep it or change it.
Who is Nenrin for?
Two kinds of people. People who want more insight into themselves and like the idea of having their life story in one place, in their own words. And people currently in therapy who want to bring more of their story into sessions, so less of the hour goes to backstory.
Can my therapist see my record?
Only if you choose. Nothing is shared by default. You pick what to share, category by category, for each therapist you connect, and you can stop sharing at any time. Your therapist reads on screen only; they cannot download or export anything, and you can see when they last looked.
What does it cost a therapist?
Nothing. A therapist seat is free. Nenrin never bills practices. Your therapist is a reader you invite, not a customer.
How much does Nenrin cost?
Planned pricing at launch is $19 a month or $149 a year, with a 14-day free trial. One plan. Nenrin is invite-only today, so the first step is the waitlist.
Do I talk or type?
Either. You can type, or tap the microphone and talk; what you say is transcribed and the audio is discarded. A full spoken conversation with Kiko, where Kiko speaks back, is in beta.
What happens to my data?
You own it. Your record is stored in your account and nobody sees it until you share a category with a therapist you connect. Nothing is sold, nothing is advertised, and nothing is used to train any model. You can export everything as a zip of Markdown and JSON at any time, and you can delete your account and all of its data at any time.
What if I am in crisis?
Nenrin is not monitored and is not a crisis service. If you are in crisis, call or text 988 in the United States, or your local emergency number. If Kiko hears something worrying, it shows one fixed card with crisis resources and does not tell anyone.
Is there an app for my phone?
Nenrin is a web app. It works in the browser on a phone, a tablet, or a computer, in light and dark mode. There is nothing to install.
Why is it called Nenrin?
Nenrin (年輪) is Japanese for tree rings: one ring for each year of a tree's life, read from the center out. Figuratively, it means the accumulated experience of a life. That is what the record is: a life, recorded one ring at a time, in your own words.
