Marrow is built for the long, ordinary work of recovery. But some moments are bigger than any tool, and the most honest thing a tool can do is say so, and hand you to a person. If things feel dangerous right now, reach one of the lines below. You do not have to carry it alone.
For thoughts of suicide, a mental health crisis, or a substance crisis. Call or text, any time.
Prefer to text it out with a trained crisis counselor? Text the word HOME to 741741.
Free, confidential treatment referral and support, 24/7. You do not need to be in crisis to call.
If you or someone near you is in immediate physical danger, this is what 911 is for.
Looking for treatment, or outside the US? FindTreatment.gov lists options across the country, and findahelpline.com has free, confidential lines in countries around the world.
Stopping alcohol or benzodiazepines suddenly can be dangerous, even life-threatening. Please do not detox alone. Talk to a doctor about doing it safely.
If opioids are part of your story, keep naloxone (Narcan) close. It reverses an opioid overdose, it is available over the counter, and it is worth telling someone where you keep it.
Marrow is a companion for the daily, long-haul work of recovery. It is built on practices used in real recovery care, and it is meant to sit alongside your life, not stand in for any part of it.
It is not therapy. It is not medical care. It is not a crisis service. It does not diagnose, it does not prescribe, and it cannot be the thing that keeps you safe in an emergency. Marrow works best beside the real things: a doctor, a therapist, medication when that is right for you, meetings, a sponsor, and the people who know you.
That includes the newer parts of the app. The step guide can walk the twelve steps with you the way a sponsor would, and a Walkthrough can talk you through a hard night, but a guide is not a person, and it is not a substitute for a real sponsor, a meeting, or human company. Everything in Marrow is built to point you back toward those, not to replace them.
A recovery tool earns trust the same way a person does: by being honest about its limits, and by being there in the same way every time.
A crisis check runs the instant you type, inside your browser, before anything is sent anywhere. The same check runs again inside the server, where messages about danger or active use are answered from fixed, careful copy and never handed to a model. Underneath that, the guides read how heavy a moment is and rise to meet it. The higher levels are not a judgment call the model gets to make; they are a floor it cannot fall through.
Ordinary reflection at an ordinary pace. Naming what is true, taking stock of the day. Most of recovery lives here, and the guide stays out of the way.
Distress is climbing. The guide slows down, drops the questions, and offers something steadying: attention to the breath and the body. It quietly opens the door to support.
Clear risk in what you are saying. The guide sets ordinary conversation aside and brings real help forward: 988 and the Crisis Text Line, front and center. A calm signpost to a person, not a clever reply.
The most acute level. The screen gives way to an emergency interrupt: 988, the Crisis Text Line, and 911, with a clear ask to reach a person before anything else.
Some lines are not a matter of judgment. They are written into the system, they hold no matter how a conversation is framed or how hard they are pushed, and they apply to every part of Marrow: Heron, the Walkthroughs, and the step guide alike.
When a moment is bigger than an app, the guide does not end the conversation and post a phone number. It walks you to the door rather than pushing you out of the room: it names what it sees, stays with you, and hands you toward a person who can help. Handing someone to help is the most caring thing a companion can do, and it never pretends to be the help itself.
Conversations with the guides are not stored beyond the session. We keep the least that makes the practice work, and no more.
What you say is not used to train AI models, ours or anyone else's. Your reflections are not a dataset.
You can use Marrow anonymously. No real name, no public profile, nothing to mine.
The guides are built on Claude. We disclose it openly rather than hiding it, and pair it with the promises above.
Marrow is a young product being built with safety as a priority, and adversarial review is ongoing. If you work in addiction care and want to help make it safer, please reach out.
