What it does
Built for real
life questions.
Not a horoscope feed. An instrument for self-understanding and decision support.
Your chart, fully understood
Every planet, house, and aspect explained in relation to your actual life — not a generic sun-sign interpretation.
Daily guidance that adapts
Personalized horoscopes, transit alerts, and weekly outlooks that reflect your unique chart, not just your sign.
AI reasoning for real questions
Career change, relationship conflict, burnout, a move — ask a real question and get a layered answer with evidence and timing windows.
Relationships, decoded together
Synastry readings, compatibility reports, and shared guidance rooms that help two people navigate their dynamic.
Journal, reflect, grow
Write freely and let Cosmo surface patterns over time — connecting life themes to astrological cycles.
Know why, always
Every reading shows which chart factors drove the answer, plus a confidence band. No mysticism — just transparent reasoning.
Under the hood
How Cosmo thinks.
Not one chat model with a prompt. A structured orchestration where deterministic chart computation is separate from interpretation, memory, and safety controls.
Chart Engine
Computes your natal chart, current transits, and synastry — exact positions, aspects, and timing windows.
Your Memory
Recalls your patterns, goals, past reflections, and what themes resonate with you over time.
Domain Reasoning
Synthesizes chart data and personal context into ranked insights for your specific question.
Safety & Grounding
Ensures reflective framing — no medical, legal, or financial overclaiming. Honest about uncertainty.
Evidence Layer
Builds the "Why this reading?" trace — which placements, transits, and memories drove the answer.
“The app should never just say ‘Mercury retrograde affects communication.’ It should say: based on your chart, this week is better for renegotiating expectations than starting a conflict — and here is why.”
How it works
From chart to clarity.
Enter your birth data
Date, time, and place. Cosmo computes your natal chart from precise astronomical data — and handles uncertain birth times gracefully.
Cosmo builds your model
Your chart becomes the foundation. As you journal and ask questions, Cosmo learns which themes recur, what tone you prefer, and what matters to you.
Ask anything
Type a real question. Cosmo synthesizes your natal chart, current transits, and personal context into a layered, honest answer with evidence.
Grow over time
Patterns surface across months and years. Cosmo tracks what keeps repeating — emotionally, in relationships, in career — and shows you the cycles behind it.
“The goal isn't to predict your future. It's to help you understand the forces shaping it — and respond with more intention.”
Early access
What people say.
“I've tried every astrology app. Cosmo is the first one that actually answered a real question I had about my career change — not just told me what Scorpios are like.”
Maya R.
Scorpio Sun · Virgo Rising
“The compatibility room helped my partner and I understand our dynamic in a way months of conversation hadn't. The timing analysis was uncannily accurate.”
James & Priya
Synastry report
“It remembered something I wrote in my journal two months ago and connected it to a current Saturn transit. That kind of longitudinal memory is what sets it apart.”
Sofia L.
Virgo Sun · Pisces Moon
“The evidence trace — seeing exactly which placements drove the reading — changed how I relate to astrology entirely. It respects my intelligence.”
