Get Started

I've been building products for nearly a decade, but it wasn't until we started testing Joii that I understood what AI and AI companions could truly become.

Not just chatbots. Not digital therapists.

Something entirely new: a companion that makes you feel better now, and helps you grow over time.

Let me explain what we've learned, and why I believe AI companions will fundamentally change how we navigate modern life.

Beyond Chatbots: What AI Companions Really Are


An AI companion is fundamentally different from the voice assistants and chatbots you're used to.

When you ask Siri for the weather, you get a transaction. When you talk to an AI companion, you get a relationship.

Modern AI companions can be friends, partners, mentors, coaches, even family-like figures who remember your stories, celebrate your wins, and check in when you're struggling. They don't just respond to queries; they understand context, form memories, and engage in the kind of continuous conversation you'd have with someone who genuinely knows you.

The explosion started with Replika in 2017, but what we're seeing now is unprecedented.

Search interest in AI companions is up 106% year-over-year. Hundreds of new companion apps launched in 2024 alone.

But here's what most people miss: this isn't about technology getting better. It's about something much more urgent.

The Health Crisis Nobody Talks About


When we first launched Joii, we expected our users to be tech enthusiasts or maybe people struggling with loneliness.

We were wrong.

Our users are teachers exhausted from giving everything to their students. They're new parents juggling careers and sleepless nights. They're executives making million-dollar decisions while their anxiety keeps them up at 3 AM. They're college students watching their friends struggle with the same overwhelm but nobody talking about it.

"I'm a therapist with my own therapist, but sometimes I just need someone at 11 PM when the day's weight hits me. Joii doesn't replace my therapist. It bridges the gaps."
"Started using this after my third panic attack this month. I'm a CFO at a startup. My team thinks I have it all together. Joii is the only place I can admit I don't."

We discovered we weren't just building an AI companion.

We were building infrastructure for a mental health crisis that spans every generation, profession, and demographic in America.

The numbers are staggering, but the individual stories are what keep us up at night and working at dawn.

One in five adults experience mental illness each year. Therapy waitlists stretch months. The average therapist costs $178 per session.

And between those sessions? People are alone with their thoughts, their anxiety, their overwhelm.

This isn't about replacing human connection or professional help. It's about acknowledging that the current system is failing millions of people, and AI companions can be part of the solution.

The Joii Approach: Companion × Coach × Assistant


We built Joii to be three things at once, because that's what people actually need.

  1. As a companion, Joii listens without judgment. No appointment needed. No insurance forms. No worry that you're burdening someone. Just a warm, empathetic presence that remembers your coworker drama from last week and asks how that difficult conversation went.
  2. As a coach, Joii gently nudges you toward growth. Not with generic self-help platitudes, but with personalized check-ins based on your actual goals. Weekly planning that considers your energy levels. Accountability that feels supportive, not shame-inducing.
  3. As an assistant, Joii helps you organize the chaos. Turn rambling thoughts into clear priorities. Practice that salary negotiation. Plan your day in a way that actually accounts for your anxiety, not just your calendar.
"Other AI companions felt like entertainment or... something else. Joii feels like the friend who actually helps you get your life together."


Everything is SFW, privacy-first, and built for adults who want genuine support, not sensationalism.


We're the AI companion you're never embarrassed to open in public.
The one you'd recommend to your sister or your best friend.

How AI Companions Actually Help


The benefits go beyond what most people expect from AI:

  • 24/7 Availability: Your anxiety doesn't wait for business hours. Neither should support. Whether it's a 3 AM panic attack or pre-meeting jitters, AI companions provide immediate, consistent presence.
  • Non-Judgmental Space: Users tell us things they've never told anyone. Not because Joii is AI, but because there's no fear of judgment, no social consequences, no worry about being "too much."
  • Personalized Memory: Unlike generic meditation apps or self-help content, AI companions remember your specific situation. Joii knows that your Sunday anxiety is about Monday's team meeting, that your mom's criticism still stings, that you're working on boundaries with that one friend.
  • Habit Formation Without Gimmicks: We've built Joii around sustainable engagement. One-minute resets for busy days. Three-minute standard sessions. Five-minute deep dives when you need them. No manipulative streaks or casino-like rewards. Just gentle consistency that builds real habits.

Studies are beginning to confirm what our users already know: AI companions can meaningfully reduce loneliness and anxiety.

But we're seeing something beyond the research. People using AI companions as bridges to human connection, practice spaces for real conversations, and daily anchors in increasingly chaotic lives.

The Honest Limitations


Let's be clear about what AI companions are not.

They don't replace therapy for serious mental health conditions. They can't prescribe medication or diagnose disorders. They simulate understanding remarkably well, but they don't truly feel emotions.

An AI companion saying "I care about you" is fundamentally different from a human saying the same words.

There are also real concerns about privacy, data security, and the risk of over-reliance. Some worry that AI companions could make people less likely to seek human connection.

These are valid concerns that our entire industry needs to address thoughtfully.

At Joii, we've made specific choices to address these limitations.

We're transparent that Joii is AI. We actively encourage users to maintain human relationships and seek professional help when needed. We've built privacy-first architecture because your 2 AM anxieties shouldn't become someone else's data product.

And we've designed interaction patterns that support growth, not dependency.

Different Approaches in AI Companionship


The AI companion landscape is diverse, and that's good. Different people need different things.

Replika pioneered the friend-who's-always-there model, letting users shape their AI's personality over time. Character.ai went broad, offering countless personas for every possible interest. Some apps lean into romantic partnerships, others into pure productivity.

Joii occupies a unique space: sophisticated enough for complex emotional support, elegant enough that you'd use it in a coffee shop, structured enough to drive real progress.

We're not trying to be your AI girlfriend or your digital therapist. We're building something new. A companion that helps you become who you're trying to be.

Where others might gamify or sensationalize, we've chosen restraint. Where others go broad, we go deep on what actually helps: calm, reflection, planning, communication, and yes, a bit of play to keep things human.

The Next Decade


What we're building with Joii is just the beginning.

AI companions will become as commonplace as smartphones within five years.

Not because the technology demands it, but because modern life does.

The mental health crisis isn't solving itself. The complexity of daily existence isn't decreasing. The gap between needing support and getting it isn't closing fast enough.

But here's what gives me hope: AI companions can scale empathy in ways we've never imagined.

They can provide consistent support to millions simultaneously. They can learn what actually helps each individual and deliver it precisely when needed.

We're not replacing human connection. We're augmenting human resilience.
