How it works

Your positions are computed, never guessed.

Most AI astrology lets a language model improvise the sky. Ritvi refuses. Real astronomy does the math; the AI only interprets. Here is the whole journey, in four honest steps.

The one rule

“The AI never computes your chart. It only reads it.”

Your chart is computed once, from real ephemeris data, and stored. Every conversation, daily reading and timing window is an interpretation of that stored chart — nothing is ever invented on the fly.

01The journey

Four steps, one honest chain.

Astronomy is deterministic; interpretation is personal. Every step below either computes something or interprets something already computed — never both at once.

01/Your details

Share your birth details.

Date, time and place — the three coordinates every real reading begins with. That’s all Ritvi asks for, and it takes about a minute.

Birth date

Birth time

Birth place

Don’t know your exact birth time? Ritvi still works — it adapts the reading to what it can know for certain.

02/Real astronomy

Real astronomy computes your chart.

A professional ephemeris — the same class of calculation an observatory would trust — computes your planetary positions, whole-sign houses, Vimshottari Mahadasha and today’s panchang, all on the Lahiri sidereal ayanamsa. The AI never does this math. Not once, not partially, not ever.

Every one of these feeds your kundli and today’s panchang.

03/Interpretation

Ritvi interprets — and shows her reasoning.

With the astronomy settled, Ritvi reads only your stored chart and current Mahadasha, then answers in your language — warm, specific, and honest about where the answer comes from. Every reply carries a “Why I’m saying this” rationale, so guidance never asks for blind trust.

Why I’m saying this

Each answer traces back to the placements it rests on — the house, the planet, the period — inside a conversation with Ritvi, in 8 languages, native script.

04/Living guidance

Guidance that lives with you.

A chart is not a one-time report. Every morning brings a fresh daily reading, timing windows mark the hours worth using, and a mood check-in keeps the ritual honest — so the sky stays useful, day after day.

  • A new daily reading, every morning
  • Timing windows for decisions and beginnings
  • Mood check-in and streaks that keep the ritual alive

02In plain terms

The words we use, defined once.

Seven terms come up throughout Ritvi. Here's exactly what each one means — no jargon left unexplained.

Ephemeris
A table of exact planetary positions for any moment in time, calculated from real astronomical data — the same kind of calculation an observatory would trust. It's why Ritvi's chart is computed, never guessed.
Kundli
Your Vedic birth chart — a map of where the Sun, Moon and planets stood, house by house, at the exact place and moment you were born.
Ayanamsa
The correction Vedic astrology applies to line the zodiac up with the stars you can actually see, rather than the seasons. Ritvi uses the Lahiri ayanamsa — the standard sidereal reference across Indian Jyotisha.
Mahadasha
A planetary period — one of nine chapters your chart moves through in a fixed 120-year cycle, each ruled by a different planet's themes. Ritvi tracks where you are in yours, so guidance knows what season you're in.
Antardasha
A sub-period nested inside a Mahadasha — a shorter planetary chapter that sharpens exactly what that longer season feels like right now.
Panchang
The day's Vedic almanac — tithi, nakshatra, sunrise, sunset, rahu kaal, abhijit. Ritvi reads today's panchang alongside your chart for daily guidance.
Kundli Milan
The traditional Vedic compatibility match between two charts. The Ashtakoota system scores eight kootas — temperament, mindset, health and more — out of 36 points, alongside a separate check for Mangal Dosha.

03Built private

The architecture keeps the promise, not just the copy.

01

Keys never touch your phone

The AI is called through secure server functions. API keys live server-side only — never inside the app on your device.

02

Your birth data stays yours

Birth details are used only to calculate your chart. Never sold, never shared for ads, never sent to analytics.

03

Conversations stay private

What you ask Ritvi is private to your account. Memory is opt-in — nothing is remembered until you approve it.

Honest, always

Two things we’d rather say plainly.

No exact birth time? Still fine.

Ritvi adapts the reading to what can be known with confidence, instead of pretending precision it doesn’t have.

Reflection, not prescription.

Astrology in Ritvi is for reflection and entertainment. It is not medical, legal or financial advice — for those, please talk to a qualified professional.

Four steps. One minute of setup. A lifetime of sky.
