The sky the minute
you were born —
finally readable.
Stellara computes your real planetary positions with Swiss Ephemeris, then lets AI turn them into a reading that actually sounds like you. Horoscopes, tarot, synastry, dream work and palmistry — all tuned to your exact birth sky.
Free to start with a 20-coin welcome bonus · No card required
The same horoscope, sent to millions of people.
Most astrology apps just reuse one generic text per star sign. They never look at your sky — your exact minute, your exact city — so the reading could belong to anyone.
One chart. Yours. Computed.
Stellara starts from real ephemeris data and pinpoints 14 celestial points the moment you were born — from your Ascendant to Chiron and the lunar nodes — and only then asks AI to interpret. The math is never invented; only the words are.
Seven readings, one chart underneath
Every feature is personalized to your real birth sky — and shows its work.
Reads your transits, not your sun sign
Every forecast is built from today's planetary transits laid over your natal chart — with love, career, health and finance rated, lucky numbers, and the colour of your day.
Computed, not guessed
Swiss Ephemeris places all 14 points to the exact degree, including your Ascendant and Midheaven. AI writes the interpretation; the positions stay astronomically true — retrogrades and all.
A real deck and a real reading
Draw your Card of the Day from a full 78-card deck, hand-painted, with upright and reversed meanings interpreted for your sign and your moment — keywords included.
Compares two whole charts
Real synastry — your planets against theirs — scored dimension by dimension, with the strengths and the friction spelled out. No sun-sign shortcuts.
Reads dreams through your chart
Tell Stellara your dream. It asks a clarifying question, then reads the symbols through your Moon, Neptune and the houses of your own natal chart — in conversation.
Both palms, seven lines, eight mounts
Photograph both hands. AI compares your dominant and passive palm across seven lines and eight mounts, then ties the reading back to your chart.
Ask the sky anything
A chat companion who already knows your sign, your placements and today's sky. Ask anything, any time, in plain words — Lyra answers in context.
Your moon, every day
A living lunar calendar with the current phase, illumination and what the day's energy is good for — month at a glance.
And quite a bit more
The small things that make it a daily companion.

We do the astronomy
Swiss Ephemeris computes your 14 points and today's transits. No guessing.
AI does the reading
Personal, plain-language interpretation across every feature — and Lyra for follow-ups.
The AI interprets your chart — it never invents it
A hybrid engine: professional-grade astronomy, computed; then AI, only for the words.
The astronomy is computed, not AI-guessed
Stellara uses a hybrid approach: the exact astronomical calculations are performed not by AI but by a dedicated server module built on Swiss Ephemeris. Your planetary positions, Ascendant, houses, transits, retrogrades and the other elements of your natal chart are computed mathematically from your birth date, time, place and timezone.
AI interprets real data — it doesn't guess your chart
Stellara then hands the finished, computed data to Google's modern Gemini model, which doesn't "guess" the chart but interprets the real astrological indicators in plain human language. This combines the precision of professional ephemeris with the power of AI interpretation: you get not a generic horoscope but a personal explanation of your chart, transits, compatibility, numerology, lunar phases and other practices — in a single system.
AI as a personal astrologer-translator
What makes Stellara unique: here AI works like a personal astrologer-translator — it explains the complex symbols, connections and influences, but always leans on a pre-computed chart rather than conjuring one out of thin air. That makes the answers more stable, more personal and protected from the typical mistakes of generative AI.
Made for how you read the stars
Whether you want the math or just the meaning.
The curious newcomer
"Explain my chart like a person would." Lyra and plain-language readings meet you where you are.
The data-minded skeptic
"Show me the math." Exact degrees, retrogrades and the full planetary data, on screen.
The relationship reader
"Is this actually a match?" Real synastry, dimension by dimension.
The daily-ritual keeper
"Coffee, horoscope, tarot, affirmation." A morning dashboard built for the habit.
Stellara shows its work
Open the horoscope and scroll: every planet's sign and degree for today, your natal positions, retrogrades marked, your Ascendant to the degree.
A reading is only as trustworthy as the chart it's built on — so we put that chart right on screen.
Loved by skeptics and believers alike
"I went in a skeptic. The natal chart matched my birth certificate to the degree, and the writing actually sounded like me."
"The compatibility report read our two charts, not our star signs. It named the exact thing we always argue about."
"Horoscope, tarot and affirmation every morning before coffee. It's the first app I open."
"I tell Stellara a dream and it answers through my own Moon and houses. Spooky in the best way."
"Lyra explains things like a patient friend. I finally understand what my Ascendant means."
"Fourteen points, the lunar nodes, palmistry that compares both hands. This is the deep end, and I love it."

Questions, answered
Real. Stellara computes your actual planetary positions with Swiss Ephemeris — the same engine professional astrologers use — before any interpretation is written.
It helps a lot — birth time sets your Ascendant and houses. You can mark your time as exact, approximate, or unknown, and Stellara adjusts how confidently it reads houses.
Google's Gemini AI writes the readings. The astronomy is computed separately and is never AI-generated, so the chart underneath is always accurate.
Six interface languages, and AI-written content in fourteen.
Partner details and your reading history stay on your device. The app stores readings tied to your account, not a public profile.

The same Swiss Ephemeris — inside your AI agent.
Stellara MCP gives Claude, Cursor, Hermes and any MCP-capable agent exact natal charts, transits and synastry as JSON. The engine computes; the agent interprets. No hallucinated house cusps.
What your agent gets
An open-source MCP server (npm package stellara-mcp) — or a remote connector by URL, no install — that talks to our astronomy API.
- 4 tools: resolve birth place, natal chart, transits, synastry
- 14 points, 12 house cusps, 10 house systems, exact aspect orbs
- Historically correct time zone & DST for the birth instant
- Guided birth-profile intake prompt — nothing stored on our side
Get an API key
Free — 5 requests a day to try it out. Stellara API Pro — 5 000 a day for $9 / month, cancel anytime. Keys arrive by e-mail within a minute.
This is the MCP entry for your agent’s config: it launches the stellara-mcp package locally (Node.js 18+) and passes your key to it. Replace sk_stellara_... with the key from the e-mail.
{ "mcpServers": { "stellara": {
"command": "npx", "args": ["-y", "stellara-mcp"],
"env": { "STELLARA_API_KEY": "sk_stellara_..." }
} } }What Free covers: every tool call is one request. Birth place → coordinates (1) + natal chart (1) = a complete chart with houses and aspects; today’s transits +1; synastry with a partner +2. Five a day = one full reading every day. The interpretation is written by your agent and is unlimited.
How to connect
Add the entry to your agent, then restart the app — the four Stellara tools appear after the restart.
By URL, no install — Claude, ChatGPT, Grok
Claude.ai / Claude Desktop: Settings → Connectors → Add custom connector → URL https://mcp.stellara.natlex.it/mcp → Connect → sign in with your Stellara account (the app account; Free: 10 requests a day, Stellara Pro: 5 000). Claude Code: claude mcp add --transport http stellara https://mcp.stellara.natlex.it/mcp, then /mcp to sign in. Other clients with remote-MCP support (ChatGPT developer-mode connectors, Grok, Cursor, Windsurf): paste the same URL and sign in. No key, nothing to install.
Claude Desktop
Settings → Developer → Edit Config → paste the entry into claude_desktop_config.json (Windows: %APPDATA%\Claude\, use "npx.cmd" instead of "npx"; macOS: ~/Library/Application Support/Claude/) → restart Claude.

What to ask your agent
Send everything in one message. Birth time is the local clock time at the place of birth (not your current time zone); say whether it is exact or approximate — that decides how confidently the houses are read.
