An AI astrologer that works from your birth chart
AstroChart.ai is an AI astrology chat app built around the birth chart. Save birth details once, ask a question in plain words, and it runs the relevant calculation, whether Western astrology, Vedic, BaZi, Human Design, numerology or astrocartography, before explaining the result in the same conversation. It runs in the browser and on Android; an iOS app is listed as coming soon.
Calculation specialists behind one chat
There is no need to pick a system before asking. Each question is routed to the right specialist, and the site's sample conversations show what each one calculates:
- Western: planets, houses and aspects, read through the Sun, Moon and rising combination.
- Astrocartography: the birth chart projected onto a world map, with planetary angle lines and nearby cities and crossings; one sample looks at Lisbon.
- Vedic: a sidereal chart on the Lahiri ayanamsa, the Ascendant, Moon and Nakshatra, and the current Dasha period.
- Numerology: core numbers such as Life Path, Expression and Personal Year, worked out from the birth date and chosen name, with both Pythagorean and Chaldean systems.
- Human Design: personality and design dates, centers, gates and channels, leading to Type, Strategy and Authority.
- BaZi: the Four Pillars calculated from local birth time and time zone, with the Day Master, hidden stems, Ten Gods, stem and branch relationships, and Da Yun luck periods.
Every answer can open into the calculated chart, and follow-up questions stay in the same thread.
A daily check-in that starts with mood
The daily view asks how the day feels, with options like calm, focused, overwhelmed or low energy, then pairs the answer with the day's astrological timing, such as the Moon's sign, and suggests a next step. The weekly view is about timing and priorities, and longer conversations cover relationships, purpose and future chapters.
Life Predictor
Life Predictor lays longer periods out as a timeline, each one named for a planet. The sample runs Venus Connection, Mercury Expression, Moon Belonging and Mars Action. It explains the move from one chapter to the next without treating the future as fixed.
Saved people and compatibility
A partner, friend or family member can be saved once. After that, it is possible to ask about them, compare charts, and check compatibility and shared timing without re-entering birth details, with every follow-up kept in one conversation.
More than 90 languages
The chat works in more than 90 languages, including English, Spanish, Chinese, Japanese, Korean, Hindi and Arabic. Answers lead with a plain explanation; technical values and full charts are there for anyone who wants them.
Moon, retrograde and celebrity chart tools
The site also has standalone tools: a Compatibility Calculator, Celebrity Charts, a Moon Soulmate Test, a moon calendar, Moon Tonight, full and new moon dates, 2026 eclipses and retrograde planets, Mercury Retrograde and a Saturn Return Calculator.
Free account, paid full reports
A free account saves the birth profile and keeps conversations together, and it is free to start with no credit card. Complete reports are a purchase: they follow the same sections as the site's sample reports, recalculated for the person's exact birth date, time and place. The Android app is on Google Play. iOS is listed as coming soon, and on iPhone or iPad the site can be added to the home screen.
