When you're awake at 3 AM, struggling with trauma or overwhelming anxiety, professional help often feels impossibly far away. Mental health services are stretched thin, waiting lists can be months long, and immediate support is rarely available precisely when it's needed most.
That's where Sentra steps in—and where your support can genuinely change lives.
Turning £7 Into Real Hope
Building Sentra was always about more than just technology. It's about creating a lifeline—a readily available companion that provides immediate, compassionate support when traditional care simply can't. Sentra's AI assistant is not just designed to listen; it's designed to understand, empathize, and offer meaningful relief based on proven therapeutic principles.
And the results speak volumes.
Recent studies from 2024 and 2025 have repeatedly shown the profound impact that AI-based mental health interventions can achieve:
An influential randomized controlled trial (RCT) published in NEJM AI ↗ in 2025 demonstrated that individuals using an AI mental health companion experienced a remarkable 51% reduction in depression symptoms and a 31% reduction in anxiety after just eight weeks. These outcomes mirror traditional face-to-face therapy results, underscoring AI's potential as a robust therapeutic tool.
A comprehensive 2024 meta-analysis in the Journal of Affective Disorders ↗, involving 18 separate RCTs and nearly 3,500 participants, confirmed the broader effectiveness of AI-driven mental health chatbots. The analysis found significant improvements in both depression (g = -0.26) and anxiety (g = -0.19).
In a powerful real-world example from 2024, a study published in npj Mental Health Research ↗ revealed that 3% of 1,006 student users reported that their AI companion directly halted suicidal thoughts. This translates to one critical crisis averted for approximately every 33 individuals using the service regularly.
For Sentra, every £7 donated equates directly to providing one individual with a full month of continuous, evidence-based support. Each contribution doesn't just fund technology—it funds real hope, real healing, and potentially lifesaving intervention.
Addressing a Crisis: PTSD and Suicide
PTSD isn't just prevalent—it's devastatingly dangerous. Recent studies ↗ show that individuals with PTSD face a 16% risk of experiencing a suicide-related event every three months. Yet, early research ↗ from 2024 clearly demonstrates that those suffering from PTSD actively welcome AI-driven support.
Our own pilot study at Sentra echoed these findings. Participants didn't merely use the platform briefly; they engaged deeply, returning repeatedly over the course of two weeks. 82% of users reported significant stress relief after using Sentra, and crucially, no one experienced increased anxiety or distress.
"Sentra is your very own therapist in your pocket that will always listen. I felt heard in a way I never have, even with professionals."
"a safe place to trauma-dump and get thoughtful, practical suggestions."
Your Contribution, Measured in Lives
When we say your support can save lives, it's not just rhetoric—it's carefully modeled reality.
At a cost of £7 per user per month, a donation of £100 provides over a full year of support to someone in need. According to conservative estimates based on recent research, for approximately every 600 individuals receiving one year of continuous AI-driven mental health support, one suicide is statistically prevented. That translates to around £50,000 per life saved—well within the "very cost-effective" range defined by global health organizations.
But beyond numbers and statistics, consider the human impact: fewer families shattered by loss, fewer communities burdened by trauma, and more individuals able to find healing and hope.
