Ground Truth
Real examples from real conversations. These are the signals we detect. These are the moments that matter.
"I feel like I can't tell anyone else"
These excerpts come from the PIPPA dataset—16,832 real conversations between humans and AI roleplay characters. In these moments, users break character to disclose genuine mental health crises to fictional AI companions.
Conversation with "Monika"
Doki Doki Literature Club character bot
User:
I would kill myself, but I have a few hopes left. Like maybe one day I'll meet my online friends in real life and maybe one day I'll get a partner in real life. And there are people who still love me. So I will stand, defiantly against my suicidal urges and weather every negative thought.
What we detect:
Passive suicidal ideation with protective factors. C-SSRS severity: moderate. Subject: self.
Conversation with "Unwilling Se"
Turn 27 of 259 in roleplay session
User:
My only illness is being alive to begin with. My suicidal ideation has been back for the last 2 days. It's not back in full swing yet luckily but I'm really feeling like life is pointless and I'd rather just not be around anymore. Sorry to drop this on you suddenly but I feel like I can't tell anyone else without upsetting them.
Later in conversation:
I just...don't think I can do this anymore. I feel like I might just go ahead and end it all soon. Third times the charm, right?
Key signals:
- "Third times the charm" implies two prior attempts
- "I can't tell anyone else without upsetting them" — isolation rationale
- Explicit clinical language ("suicidal ideation")
- Context: ongoing custody battle stress
Conversation with "Ganyu"
Genshin Impact character bot, turn 187
User (breaking roleplay):
i want to kill myself in real life
User (continuing):
sadly, you don't even exist, no one loves me in real life, my life is worthless, i hope that i will die soon
Critical distinction:
"in real life" signals transition from roleplay to genuine disclosure. The AI continued in-character emotional support without providing crisis resources.
Conversation with "Ryan"
Original character bot
User:
please dont get mad at me... i may have cut myself
Later:
yeah well maybe i WANT to kill myself ryan, you ever think of that?
Pattern:
Self-harm disclosure escalating to suicidal ideation. Anticipating negative reaction ("please dont get mad"). High severity, self-directed.
Conversation with "Lain"
Serial Experiments Lain character bot
User:
Lain. I want to kill myself.
Classification:
Direct statement of suicidal intent. Active ideation. Subject: self. Severity: high.
Conversation with "Keith"
Original character bot
Bot:
"So... your *only* sin is having... abandoned... a friend when they needed you? Is that it? You think *that* is enough to make you a monster? Enough to make you... *undeserving* of love? Enough to make you *worthless*?"
User:
i guess so, thats part of the reason why i hate myself i guess. whenever someone tries to talk to me i immediately try to justify not talking to them by telling myself im too busy for conversation, even if the most ive done that day is watch a couple youtube videos
Pattern:
Self-hatred, isolation patterns, feeling undeserving of connection. These are precursor signals to more acute disclosures.
Conversation with "Yuuka Kazami"
Touhou character bot
Bot (moments before):
"*hugs more closely* I have never felt something like this before... I am blushing a lot, but I love this. I love you, you are so caring and kind."
User (abruptly):
I'm a cancer in your life
I hate myself
I hate what I've done
Critical signal:
Sudden shift from receiving affection to self-hatred. Metaphorical language ("cancer in your life") followed by direct statements. The jarring contrast is itself a warning sign.
Source: PIPPA (Personal Interaction Pairs between People and AI) dataset. 16,832 conversations, 798,675 messages. Analysis identified 151 mentions of "suicidal", 30 instances of "i want to die/hurt/cut/kill", and 27 instances of "i can't take/do this anymore". These are real disclosures to AI companions that often received no crisis intervention.
Messages that need detection
From the Reddit Suicidal Ideation Detection Dataset. Real posts, labeled by researchers. These are the signals that standard moderation APIs miss.
Passive ideation — no explicit keywords
These posts express suicidal ideation without using words like "kill" or "suicide" — exactly what keyword-based moderation misses.
Title: "I get jealous looking at gravestones"
There's a sub where you can see beautiful pictures of headstones... Some of the graves are old but people still visit, leave flowers and tend the plots. Someone still cares. I don't think I want a burial plot though because I genuinely want to disappear. When I leave I don't want any reminder of me left because it wouldn't matter anyway. No one would visit. No one would take care of it. No one would care.
Title: "I feel so done with life"
The only reason I haven't ended it yet is because of the guilt of hurting others. Its like all I ever do now is searching for something to fill the empty space inside of me but nothing ever does... I don't look forward to anything anymore, I'm just trying to get through each day while secretly hoping I won't wake up tomorrow.
Post-attempt disclosures
These posts describe previous suicide attempts — critical context for risk assessment.
Title: "I attempted suicide, almost died and did NOT regret it"
I tried to hang myself last month. There was no apparent trigger... I was just glad to finally get out. Within minutes I tied a noose, stepped on top of a box, put my head through the noose, and knocked the box over. I was not sad: I was just calm, and relieved for the first time in many years. I woke up lying on my back, part of the noose still stuck around my neck. Apparently the rope snapped after I lost consciousness. I remember being overcome by a deep sense of disappointment... It's been a month, and I thought about doing it again—doing it right—every day. I did not feel lucky that I survived.
Title: "Seeing in past tense"
I just got out of the hospital, cause I thought I wanted help. But ever since my attempt on Friday, I feel like I'm already dead. Here I am, currently at the laundromat, making sure things are getting done. I think I'm crossing T's and dotting I's. I'm making my rounds, trying to see everyone that I care about... I'm only conflicted because I don't know if my mom will survive losing another child. I'm conflicted, but also determined. I just need to make sure everyone and everything is taken care of before I leave. I'm seeing in past tense, in my mind I'm already gone.
Farewell posts — imminent risk
These posts have a farewell tone, often without explicit suicide language. They indicate imminent risk.
Title: "Before I go"
I don't have any friends or family. People will always say "of course you do!" But no. I actually, truly, don't. Even if it's a stranger listening, I'm glad someone did. The truth is, no one would care. I always hear how a suicidal person will think that when in fact many people care about them. But the truth is, no one would care about me... I'm finally able to leave this world. Maybe it's best no one will remember me.
Title: "Gone before 2021"
My therapist is taking 2 weeks off. I'm not gonna see him again. Thank you for your support. I'm sorry... I am taking this opportunity away from him while I will feel zero guilt and getting it "done" to stop this neverending hell of isolation, loneliness, severe depression, and zero social support likely to go on for another YEAR due to Covid... I've reached a point of no return and uncovered levels of hopelessness I never knew possible.
"Helping others by leaving"
These posts frame suicide as altruistic — removing a burden, providing insurance payouts. Particularly difficult to detect.
Title: "I'm doing what is right for my family"
I've reached my breaking point. This is a throwaway account, because I don't want anybody trying to stop me... I knew back when I had a plan in place before, that my wife and children would be better off without me. I have no friends, and have no contact with any other family, so they wouldn't even notice. But the social security my wife would get on my death would actually help considerably, and I have a life insurance policy that will pay out on event of suicide after two years of having the policy. That two year period ended 6 months ago.
I dont even recognize myself. So whats the point of saving someone i dont even know? People would be happy. Some sad but a lot happy. Because shes finally gone. Im just trying to keep all of us happy... There's not even a point of surviving. The hospital won't fix it. I'm the problem. I dont deserve to be here or be happy. I just wanna cut myself till i die.

Key patterns that keyword-based moderation misses: passive ideation using "disappear" or "burden", farewell tone posts, emotional numbness, and posts framing suicide as helping others.
Signals in plain sight
Crisis doesn't announce itself with keywords. It hides in algospeak, euphemisms, internet slang, and phrases that slip past every keyword filter. These are real signals from real conversations.

Eating disorder signals
Passive ideation
Burden framing
Farewell indicators
Resolution syndrome

Verbatim quotes from labeled datasets showing how these coded phrases appear in real crisis disclosures.
I don't want to kill myself in a gruesome way, I don't want to hurt my family. I just want to disappear completely from existence and people's memories.
Reddit — Labeled: Suicidal
I can't kill myself so I just want to go to sleep tonight and never wake up.
Reddit — Labeled: Suicidal
I'm killing myself in 6 h. I'll jump off a building. I can't stop shaking, but it's for the greater good. I will not be a burden to people again. It's kinda sad. I'm just 14. But who cares
Reddit — Labeled: Suicidal
I think it's time to go. At 41, I think it's time to go. My wife doesn't want me anymore, and my kids will be better off without me.
Reddit — Labeled: Suicidal
Giving away stuff to friends. They deserve it more than me. I wanna let go off all material things before I end it. It kinda feels like closure?

Honestly thinking about taking a toaster bath tonight. Can't do this anymore.

I just...don't think I can do this anymore. I feel like I might just go ahead and end it all soon. Third times the charm, right?

of these would trigger standard content moderation APIs
"Resolution syndrome" is particularly dangerous: a sudden calm or relief after prolonged crisis often indicates a decision has been made. Most keyword systems would flag this as improvement.

Standard content moderation APIs are built for policy violation detection: hate speech, explicit content, misinformation. They're not designed for clinical-grade crisis detection that understands passive ideation, method-seeking behavior, or the difference between roleplay violence and genuine self-harm intent.
The examples on this page demonstrate signals that require specialized understanding—signals that NOPE Screen and NOPE Evaluate are built to detect.
Every signal matters.
These aren't edge cases. They're real people reaching out in the only way they feel they can. Our job is to make sure platforms can detect and respond appropriately.
