Intercept harmful content

Koko detects high-risk search terms & phrases on platforms and online communities using our proprietary keyword library.

Our systems can capture up to 20-40% more keywords than traditional filters and constantly evolve to mirror new trends and slang.



We make it easy to offer a variety of support options to at-risk users in an accessible way.

From crisis lines, to support systems designed to help before a user reaches an emergency state.

Koko has reached over 2,000,000 people.

Over 90% of users found Koko helpful.

But we're just getting started. We want to see a world where people can access services like ours for free — zero friction, completely ubiquitious.

"A lot of people express online that they are struggling, and we don’t yet have a good understanding of how best to provide help and support. Koko is filling this gap and providing scientifically-supported tools to help those who are struggling. They’re figuring out what works best and then putting it to work to help people." - Dr. Matthew Nock, Ph.D.

Shielding users from harmful mental health content isn’t just sensible business, it’s the right thing to do.

As the U.S. Surgeon General declares youth mental health 'the defining public health crisis of our time,' the stakes have never been higher for the well-being of young people navigating social media at increasingly younger ages.

Now, more than ever, it is imperative for social media companies to rise to the challenge and create a safe, supportive space for their users. Though the task may be complex, we are here, committed to helping you make a lasting, positive difference.
