Letheia: Mood Magic for Your Inner World
Letheia (leh-thay-uh) is where you go when your head feels loud. A place to check in, clear your head, and say what's actually real.
Not a therapist. Not social media. Just a truth-telling space for Gen Z feelings.
—
Feeling something? Let's check in.
• Tap an emoji for a quick read, or go deeper with the 3-level Emotion Wheel — "Angry" to "Frustrated" to "Overwhelmed."
• Say it or type it... no judgment
• Get a personalized AI reflection that actually mirrors your emotional state
• Unlock "Truth Threads"... AI-crafted affirmations that sound like you, not a fortune cookie
• Save the ones that hit and come back to them later
—
Talk it out with Letheia Chat
Sometimes a check-in isn't enough. Open a full conversation with Letheia's AI... it listens, mirrors, and helps you process in real time. Not advice. Not therapy. Just something that actually gets it.
—
Breathe with the Orb... 14 breathwork exercises synced to sound, haptics, and rhythm. Breathe in. Breathe out. Feel the difference.
—
Chill Zone... Too much? Tap it out. When your brain needs a break, not a deep dive.
• Flip the Feel
• Mood Match
• Whack a Mood
• Slide the Vibe
• Mood Blaster
Your brain deserves a snack break. These games are the chips.
—
See your patterns... Track how your emotions move over time.
• Mood + Energy Map
• Weekly Rhythm
• Time of Day
• Top Vibes
No pressure. No streaks. Just awareness.
—
Make it yours
• Customize your vibe
• Switch between emoji and wheel mode
• Reorder your dashboard
• Set your breath style and weekly intentions
—
Now on Apple Watch
• Quick Mood Check-Ins from your wrist
• Guided breathwork on the go

—
Built with Safety at the Core. Letheia runs on TruthSafe™, our patent-pending AI safety system. Designed for honest emotional expression with grounded, non-clinical responses.
No mind-reading. No diagnosing. Just human-first AI, built to listen safely.
—
Shaped by Mental Health Professionals
Letheia is guided 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
• People who say "I'm fine" but aren't
• Anyone who just wants something that actually gets it
You don't need to be fixed. Just met with truth.
