Cyrus is an AI emotional support tool built from the real clinical knowledge and experience of licensed mental health practitioners. It's constantly being updated with the current practices and strategies of practicing therapists.
Every response is shaped by clinicians who are in the room with real clients every week, people who understand what it actually means to sit with someone.
It is not a therapist. It will tell you that. But a lot of people are using AI for help and a lot of therapists want to meet you where you are.
Safety is checked before anything else, including whether you are a subscriber. It reads what you mean rather than matching keywords. It draws on a knowledge base contributed by practicing clinicians, who are paid every time their knowledge is used. And it responds the way they taught it to — curiosity before conclusions, and no easy agreement.
Just as deliberately: it isn't therapy, it doesn't keep you here, and it never learns from your conversations.

Try it freeMore and more of my clients are using AI between sessions. Sometimes it helps them. Sometimes it makes things significantly worse, because it doesn't know what it's doing clinically. It just sounds like it does.
So I started looking into what was actually out there. And here's what I found: there are platforms that mention a PhD on their website. There are some that say their AI is "trained by psychologists." But I couldn't find a single one actually built and operated by practicing therapists, people who are in the room with real clients every week.
Therapists are expensive, hard to find, and only available 50 minutes at a time. That gap is real and it affects people who are already struggling. And in that gap, people are turning to whatever is available.
We are all going to use these tools. That's just reality. The question is whether those tools are built by people who actually understand what they're doing, or by technologists who see mental health as a market.
I'm a Licensed Clinical Social Worker. I work in an Intensive Outpatient Program that serves my local community and a local residential recovery program in western Massachusetts. I built Cyrus from the clinical knowledge and experience of practicing therapists across different specialties and perspectives, grounded in actual frameworks, designed to listen before it says anything.
It's not a therapist. It tells you that. But it's the most clinically honest version of this that I know how to build, and I'm building it with other clinicians who care about the same things I do.

Cyrus Mental Health LLC ("we," "us," or "our") operates the Cyrus platform. We take the privacy of your personal and conversation data seriously — particularly given the sensitive nature of emotional health discussions. This Privacy Policy explains what data we collect, how we use it, and your rights over it.
By using Cyrus, you consent to the practices described in this Policy.
2.1 Account Information
When you create an account, we collect:
2.2 Conversation Data
When you use Cyrus, we collect and store:
Conversation data is among the most sensitive information we handle. We treat it accordingly and do not use it for purposes beyond those described in this Policy.
2.3 Voice Data
If you use the voice (text-to-speech) feature, audio is generated in real time and is not stored on our servers. Voice synthesis is handled by ElevenLabs; please review their privacy policy for details on their data handling.
2.4 Usage Data
We automatically collect certain technical information when you use the Platform:
2.5 Notes Tool Data
If you use the in-app notes or journaling feature, your notes are stored and linked to your account. This data is subject to the same protections as conversation data.
We use your data solely for the following purposes:
We do not sell your data to third parties. We do not use your conversation data for advertising. We do not share your conversation data with other users.
4.1 Where Your Data Is Stored
Your data is stored in a secured cloud database (Supabase/PostgreSQL) with encryption at rest and in transit. Application infrastructure is hosted on Vercel. Both providers operate with industry-standard security controls.
4.2 Security Measures
4.3 Pseudonymization
To further protect your privacy, we separate directly identifying information (such as your name and email address) from your conversation data using a unique internal identifier. Your conversation records are stored under this identifier rather than under your name. Only authorized personnel with access to the linking key can connect your identity to your conversation history. This approach limits exposure of sensitive conversation content in the event of a data incident.
4.4 Data Retention
We retain your conversation data for as long as your account is active. If you delete your account, we will delete your conversation data within 30 days, except where retention is required by law.
We share data with the following third-party providers solely to operate the Platform:
Each provider processes only the data necessary to perform their service. We do not authorize any provider to use your data for their own purposes beyond service delivery.
5.1 International Data Transfers
Some of our third-party service providers — including Anthropic, OpenAI, ElevenLabs, AssemblyAI, and Pinecone — may process your data on servers located outside the United States or the Commonwealth of Massachusetts. By using the Platform, you consent to the transfer of your information to these providers in accordance with this Privacy Policy.
We take steps to ensure that any international transfers are handled with appropriate safeguards and in compliance with applicable law. However, please be aware that data transferred internationally may be subject to the laws of the countries in which it is processed, which may differ from the laws of your home jurisdiction.
5.2 Third-Party AI Services
Cyrus uses Anthropic's Claude API to power AI-generated responses within the app. When you send a message, the text content of that message is transmitted to Anthropic's servers for processing. Anthropic returns a generated response which is displayed to you in the app.
Anthropic's data practices are governed by their own Privacy Policy, available at anthropic.com/privacy. Anthropic does not use your conversation data to train their models and provides data protection equivalent to the standards described in this policy.
5.3 Voice Transcription and Knowledge Base Search
Cyrus uses OpenAI's API for two purposes. If you record a voice message, the audio is transmitted to OpenAI's Whisper service and converted to text. Separately, the text of your message is converted into an embedding — a numerical representation of meaning — so it can be matched against our de-identified clinical knowledge base.
OpenAI's data practices are governed by their own Privacy Policy, available at openai.com/policies/privacy-policy. OpenAI states that data submitted through their API is not used to train their models.
Beyond the providers named in this section, Cyrus does not share your data with any other third-party AI services, and we do not sell your data to any third party.
You have the following rights regarding your personal data:
To exercise any of these rights, contact us at hello@cyrusmentalhealth.com. We will respond within 30 days.
Cyrus does not require you to create an account or password. If you have provided an email address, you may request deletion of your conversation data at any time by emailing hello@cyrusmentalhealth.com. Deletion will be processed within 30 days of your request. Step by step instructions are on our account deletion page.
Cyrus is designed for emotional support conversations, which may include sensitive disclosures — including but not limited to mental health history, trauma, substance use, and relationship issues. We treat all conversation data as sensitive by default and apply heightened protections accordingly.
We do not use sensitive disclosures for profiling, targeting, or any purpose other than providing the continuity features described in this Policy.
Cyrus is not intended for users under 18 years of age. We do not knowingly collect data from minors. If we become aware that a user is under 18, we will delete their account and all associated data promptly. If you believe a minor has created an account, contact us at hello@cyrusmentalhealth.com.
We may update this Privacy Policy from time to time. We will notify registered users of material changes by email and will post the updated Policy on the Platform. Continued use of the Platform following notice of changes constitutes acceptance of the revised Policy.
For privacy-related questions, requests, or concerns:
Cyrus Mental Health does not use passwords. If you entered an email address in the app, that email address is your account, and it is the only thing that links your conversations to you. If you never entered an email address, your conversations are stored only on your device, and deleting the app removes them.
Delete my account.Writing from the address you used in the app is how we know the request is yours. We do not ask for anything else.
Within 30 days of your request we delete:
You may instead ask us to delete your conversation data only and keep your email address usable in the app. Say so in your email and we will leave your email address in place.
Most AI will tell you what you want to hear. Cyrus was built by practicing clinicians to do something harder — listen well, stay honest, and draw on real clinical knowledge when it responds. Here is exactly what happens when you talk to it.
Before anything else — before it even checks whether you are a subscriber — your message is checked for signs of crisis. If they are there, everything stops: you get a full response and real crisis resources (988, the Crisis Text Line at 741741, and 911 for immediate danger). An expired subscription does not change that. The order of operations was built so that safety outranks revenue, every time.
"It just feels far away again, I guess" is not a search term — it is a feeling. Cyrus reads your message in the context of your conversation and works out what is actually being said: the longing under the metaphor, the worry under the joke. That understanding, not keywords, is what it carries forward.
Cyrus holds a knowledge base built from the notes, training, and thinking of licensed, practicing clinicians — how people who listen for a living actually work. The most relevant pieces are pulled in to inform the response. And every time a clinician's knowledge is used, they get paid for it. That is the deal that makes the knowledge real.
Curiosity before conclusions. Questions before advice. It starts from the assumption that what you are doing makes sense given what you are carrying — and it will not just agree with you to keep you comfortable. When something needs a real person, it says so and helps you find one.
No diagnosis, no treatment, no medical advice — and it tells you that plainly, from the first screen. It is a place to think out loud, built by people who know exactly where that line is.
Sessions run 90 minutes and end on purpose. As the end approaches, Cyrus winds the conversation down rather than cutting you off mid-thought, and it will tell you how much time is left whenever you ask. If you are subscribed, it says before the session closes that there is a one-hour break before you can begin a new one — so the ending is never a surprise. Most people use about 20 minutes. It is built to send you back to your life, not to maximize your screen time.
The clinical knowledge comes from clinicians who chose to contribute it. Your conversations are never added to it. What you say is used to remember you and respond to you — not to train the knowledge base.
$9 per month on the web, $12.99 on iPhone — and your access follows you between them. Before that, everyone gets 90 minutes free to try.
We are showing you the whole machine because we think honesty is the product.
Cyrus is built by practicing therapists and we want to keep it that way. Contribute your clinical voice and get paid every time it's used.
Cyrus's knowledge base is built from the de-identified clinical experience and philosophical frameworks of licensed practitioners. When you contribute, you complete a detailed clinical philosophy form covering your orientation, your approach, and your hard-won perspective. That material shapes how Cyrus responds to real people in real moments.
Cyrus is early. The compensation that makes sense depends on the stage, so here is all of it, including the parts that are small today.
The first contributing clinicians receive an equity stake in Cyrus Mental Health LLC from a reserve pool, on a vesting schedule, in recognition that they are building the knowledge base before there is a network to pay for it. Equity terms are discussed individually and documented in a written agreement. The number of early clinician positions is limited.
Cyrus grounds its responses in retrieved clinical material whenever the knowledge base has something relevant, and the three most relevant retrievals in every turn are recorded to the clinicians who contributed them. Clinicians are paid per retrieval in subscribers' conversations: $0.003 when a contribution ranks first in relevance, $0.002 for second, $0.001 for third. The arithmetic, plainly, with one conversation turn per subscriber per day: at 1,000 active subscribers, a clinician whose material ranks first in one of every ten conversation turns earns about $9 a month; at 30,000 subscribers the same share is about $270 a month. Today the amounts are cents, because the subscriber base is small. The ledger behind this already runs in production and every contributor can be shown their own numbers.
Cyrus is built to notice when a person would benefit from a human clinician, and to notice whose contributed knowledge has actually been helping that person over time. When the network is large enough on both sides, Cyrus will offer the person an introduction to a clinician whose work fits what they have been working through, filtered by location, insurance, and availability. The introduction carries only what the person chooses to share; no conversation content is transferred. This requires enough users and enough clinicians to match between, which is why early clinicians matter: you are the network.
Contribute your knowledge, own a piece of what it becomes, be paid when it is used, and be matched with the people your work already helps.
Participating clinicians get access to Cyrus Consult, a consultation interface backed by a growing knowledge base of experienced clinicians across orientations and specialties. Describe a client presentation and receive multi-perspective responses drawn from that knowledge base. A thinking partner built from real clinical experience. Your judgment stays with you.
Consult is live and in use with our early contributing clinicians. Access is invitation-only while we grow the group.
The question is whether the tools they turn to carry any real clinical weight. We think they should. And we think the clinicians behind them should be compensated for their insight, perspective, and education.
Complete the clinician interest form. We review every submission and verify licensure before onboarding. If it's a fit, we'll be in touch.
