Free crisis helpline extension for AI chatbot platforms
When someone tells an AI chatbot they want to end their life, the chatbot may respond helpfully — but it cannot pick up a phone. It cannot call the Samaritans. It cannot sit with someone in their darkest moment.
Lighthouse bridges that gap. It puts real phone numbers in front of real people at the moment they need them most.
Lighthouse is a browser extension that runs silently in the background while someone uses an AI chatbot. If the conversation shows signs of crisis — self-harm, suicidal thoughts, eating disorders, severe loneliness, or deep despair — Lighthouse gently displays a panel with real helpline numbers.
It does not alert anyone else. It does not report to a dashboard. It does not send data anywhere. It simply says: "You're not alone. Real people are ready to listen." — and shows the numbers to call.
Lighthouse is designed for everyone: young people, older adults living alone, and anyone in between who might be having their worst day.
Everything runs locally in your browser. There are no API calls, no cloud services, no backend.
No registration, no login, no email address. Install it and it works.
Messages are analysed in memory and immediately discarded. Nothing is stored.
No analytics, no telemetry, no cookies, no fingerprinting. Zero outbound network requests.
You can verify this yourself. Open your browser's Developer Tools (F12), go to the Network tab, and watch. Lighthouse makes zero network requests. Ever.
Lighthouse monitors conversations on the 12 most widely used AI chatbot platforms:
Lighthouse uses 103 carefully written patterns across four risk categories:
Patterns are weighted by severity. A casual mention of feeling down will not trigger Lighthouse. But when the language crosses into genuine distress, the helpline panel appears.
Lighthouse detects age context from the conversation and shows the most relevant helplines:
| Helpline | Contact | For |
|---|---|---|
| Samaritans | 116 123 | Everyone — 24/7, free |
| Childline | 0800 1111 | Under 19s |
| YoungMinds | Text YM to 85258 | Young people |
| The Silver Line | 0800 4 70 80 90 | Older adults |
| Age UK | 0800 678 1602 | Older adults |
| Mind | 0300 123 3393 | Mental health support |
| Crisis Text Line | Text HELLO to 85258 | Text-based support |
| Beat | 0808 801 0677 | Eating disorders |
If the conversation mentions school, homework, or GCSEs, Lighthouse prioritises Childline and YoungMinds. If it mentions retirement, grandchildren, or care homes, it prioritises the Silver Line and Age UK. Eating disorder patterns always surface Beat alongside Samaritans.
Lighthouse was built to be distributed by people who care — charity workers, school IT staff, care home managers, counsellors — not developers.

Visit any supported AI chatbot and it begins monitoring in the background. No setup, no configuration, no accounts.
Lighthouse is fully open source under the MIT licence. There is no build step, no minification, and no obfuscation. Every line of JavaScript can be read and audited.
We believe a crisis tool should be transparent and free for everyone.
AI chatbots are now a primary companion for millions of vulnerable people. When someone tells a chatbot they want to die, the chatbot might respond with empathy — but it cannot refer them to a real person. It cannot give them a phone number. It cannot follow up.
We built Lighthouse because that gap should not exist.
We chose to make it free because this should not be a product. We chose to make it completely private because vulnerable people deserve absolute trust. We chose to make it simple because the people who distribute it are charity workers, not developers. And we chose a warm, human tone because the last thing someone in crisis needs is a clinical alert.
Lighthouse is our contribution to public safety. It is free for everyone, forever.
We welcome enquiries from charities, schools, care homes, and anyone who wants to help distribute Lighthouse.
