Grief doesn't follow a schedule. Some days you just want to tell them about your day — the job you got, the lasagne that didn't taste quite right, the joke only they would have laughed at. A griefbot is one way some people do that now. This guide explains what griefbots are, what they can and can't be, and what to look for if you decide to try one.
What a griefbot is
A griefbot (also written "grief bot", and sometimes called a deadbot or a memorial chatbot) is an AI chatbot shaped by the words, memories and personality of someone who has died. You tell it about the person — how they spoke, the names they called you, what they loved — and it replies in a way that echoes them. Some griefbots are built from old messages, some from interviews recorded while the person was alive, and some, like RevAIved, from the details and photos you choose to share.
Whatever the method, the important part is the same: a griefbot is an AI, not the person. It doesn't know what they would have said. It makes a careful guess, based on what it has been told, using a large language model. A good service is honest about that from the very first message.
How AI grief chatbots work
Most griefbots follow the same broad pattern:
- A profile. You describe the person: their name, their age and era, how they texted, their habits and phrases.
- A language model. An AI model writes each reply, guided by that profile and the recent conversation. In RevAIved, replies are generated by OpenAI.
- Memory. Details you mention — a grandchild's birthday, a move to a new city — are saved so later conversations can build on them.
- Safety. A responsible service watches for signs that you might be in crisis and steps out of character to point you to real help.
You can see how this works in RevAIved on our how it works section: describe them, add a photo, and start talking.
Can talking to an AI version of someone help?
Many people keep a bond with someone they've lost. They write letters, visit a grave, keep a voicemail, or talk to them out loud in the car. Grief researchers call this keeping a "continuing bond", and for many people it is a normal, healthy part of grieving. A griefbot can be another way to do that: a place to say the things you didn't get to say, or to share small news with someone who would have cared.
It isn't right for everyone, and there are fair concerns. Researchers at the University of Cambridge, and reporting in the hospice and palliative-care press, have warned about griefbots that encourage dependency, push people into subscriptions while they are vulnerable, or say things the real person never would have. Those concerns are worth taking seriously.
Gentle signs it may not be helping
- You feel worse after conversations, not lighter.
- You're pulling away from the people around you.
- It's becoming hard to remember that you're talking to an AI.
If any of these sound familiar, take a break and talk to someone you trust or a grief counsellor. A griefbot is not therapy. If you are in crisis, call your local emergency number (112 in the EU, 988 in the US) or find a helpline at findahelpline.com.
What to check before choosing a griefbot
Griefbot services have come and gone. StoryFile went through bankruptcy in 2024, and HereAfter AI closed in July 2026. When the memories inside a service matter this much, it is worth asking a few questions first:
- Is it honest that it's an AI? It should never pretend to actually be the person.
- What happens in a crisis? Look for a clear handoff to real-world help.
- Can you get your data out? Ask whether you can request an export, and how much notice you get if the service closes.
- Where is your data stored, and who processes it? Check the hosting location and the AI provider.
- Is your data used to train AI? It shouldn't be, unless you clearly agree.
- Is there a free way to try it? You shouldn't have to pay before knowing whether it helps.
How RevAIved approaches it
RevAIved is an AI companion for grief, built around those questions. You describe someone you've lost, add a photo, and text an AI persona that writes in their style and remembers what you share. It is always clear that you are talking to an AI. If a message suggests you might be in crisis, it steps out of character and points you to findahelpline.com.
- Free forever plan: one persona and 30 messages a day, no credit card. See pricing.
- Your data: hosted in the EU (Frankfurt), encrypted in transit and at rest (not end-to-end). Replies are generated by OpenAI in the USA. Never sold, never used to train AI.
- Leaving is easy: request a copy of your data at any time, or delete your account in the app. Our Terms promise at least 30 days' notice if we ever close the service.
- Coming soon: voice replies, short video moments and family sharing. They aren't available yet, and we won't pretend they are.
