Jyotishka is a private Vedic astrology app, free to use on the web today, with iOS and Android apps coming soon. It computes birth charts using traditional Jyotisha methods (Whole Sign houses, Lahiri ayanamsha) and lets you ask an AI questions about any chart in your family.
Yes. The birth chart, dasha timeline, yogas, predictions and PDF export are all free, for every chart you create. A Premium subscription adds the Extended Report — divisional charts, Ashtak Varga and detailed Bhava analysis — with its own PDF. Premium is available monthly or annually.
Yes. Your birth details are stored securely on our servers (encrypted in transit and at rest) so your charts sync across devices, and we do not sell or share personal data with third parties. Chat runs on our servers by default: your question and a chart summary are sent to generate the reply, and we do not store the conversation. On Android you can download the Jyotishka AI model, after which conversations are processed entirely on your phone and never sent to any server. See our Privacy Policy for details.
Jyotishka is for anyone interested in Vedic astrology — whether you are Indian, part of the South Asian diaspora, or simply curious about Jyotisha. It supports charts for your whole family: yourself, your spouse, children and parents.
Yes. Janam kundli, jatakam, kundali and birth chart all describe the same thing: a map of the sky at your moment of birth. Jyotishka computes it with Swiss Ephemeris using Whole Sign houses and Lahiri ayanamsha, the conventions most traditional Jyotishis use.
Yes. Jyotishka is fully translated into English, Hindi, Tamil, Bengali, Telugu, Marathi and Gujarati — not just the buttons, but the chart interpretations, predictions and the exported PDF, which embeds the correct script for each language.
No, and this is deliberate. Tithi, vara, festival dates and auspicious days come from the astronomical calculation and a hand-verified festival calendar. They never pass through the language model. The AI can discuss what a date means, but it cannot invent or alter the date itself — and if an answer ever contradicts the calculated calendar, the app flags it and shows you the computed dates instead.
Lahiri (Chitrapaksha) by default — the standard used in India and by most traditional Jyotishis. Raman and KP (Krishnamurti) are also available in settings.
Whole Sign houses — the traditional Vedic system where each house corresponds to exactly one rasi. The lagna (ascendant) is the first house.
You can enter an approximate time or leave it blank (the app defaults to noon). The Moon sign, nakshatra and dasha timeline will still be accurate. The lagna (ascendant) will be marked "approximate" because it changes every two hours. Use the Birth Time Verification tool to narrow it down using known life events.
Yes. Jyotishka includes city data for India, UK, USA, Canada, Australia, UAE, Singapore, Malaysia and South Africa. For any other location worldwide, a global search fallback finds the correct coordinates and timezone automatically.
Very accurate. The Vimshottari dasha start date is computed from the exact Moon longitude at birth. With an exact birth time, the antardasha (sub-period) dates are accurate to within a day or two.
By default, yes — chat runs on our servers on every platform. Your question and a chart summary are sent to our AI provider to generate the reply; the conversation content is not stored on our servers. On Android you can download the on-device model, after which the language model runs entirely on your device and no questions or answers leave your phone. An on-device option for iPhone is not available yet. The app shows which mode you're in.
Jyotishka AI is approximately 0.8 GB and works fully offline once downloaded. It is available on Android only for now — iPhone and the web app use cloud chat. We recommend downloading on Wi-Fi.
Cloud chat works on any supported iPhone, Android phone or browser. The optional on-device model is Android-only for now and wants roughly 3 GB of RAM or more — most phones from 2018 onwards meet this comfortably. If it feels slow on your device, you can switch back to cloud chat at any time.
