What Makes Letheia Different

We don’t do likes. We don’t sell your data.
We don’t pretend journaling fixes everything.

Instead, we hold space—for your spirals, your growth, your late-night anxiety, and your moments of clarity. Letheia is emotional self-care, reimagined for those who feel deeply and think fast.

Built with Mental Health Experts

Letheia is shaped by licensed counselors and real users.
No toxic positivity—just emotionally honest tools that support your inner world.

Letheia is for:
• Overthinkers at midnight
• Tender-hearted realists
• Those who say “I’m fine” but aren’t
• Or if you just want a friend who gets it—or an AI companion to chat with for a while

You don’t need to be fixed. Just met with truth.
