compare_family

Side-by-side view of up to 6 saved people: for each of the 12 life areas (career, money, marriage, health, children ...) whether it is strong, mixed or needs care for each person (Sarvashtakavarga points), and the life chapter and phase each is in now. Use when the user asks how family members differ, who is better placed for something, or wants an overview of the family. Omit profiles to compare the 6 most recently saved. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Discovered
explain_dasha

Explains the life phase a person is in right now, what it tends to bring, when it ends and what comes next, from their birth details; or, without birth details, what a given phase means in general and how long it lasts. Useful when the user wonders why life feels a certain way at the moment, when things will change, or about timing for career, marriage, a move or a fresh start, for themselves or someone close to them. Also for direct questions: "what's my dasha", "which mahadasha am I in", "what's coming in my dasha", "meri dasha kaunsi chal rahi hai", "Shani ki mahadasha kab khatam hogi", "mera time kab badlega". Uses the Vimshottari dasha system. Two ways to call it: (1) with birth details (date, time, place) it returns the running Mahadasha and Antardasha with exact start/end dates, what the period is about for that chart and the next antardashas (AstroCalc engine); or (2) with lord (and optionally antardasha) set to a planet, e.g. lord "Saturn", antardasha "Venus", it returns the general meaning and length of that period, with no birth data needed. Birth details are not stored. Traditional information, not a prediction.

Discovered
free_kundli

Reads a person's birth chart from their date, time and place of birth: their core nature, the life phase they are in now and when it changes, the standout strengths in the chart, and which life areas look strong or need care, with what helps. Useful when the user talks about themselves, a family member or someone they know and wants to understand them better: personality, a life change, career or marriage timing, feeling stuck, or what to work on. Also for direct requests in English, Hindi or Hinglish: "make my kundli", "kundli for my birth details", "what is my rashi / lagna / nakshatra", "meri kundli banao", "janam kundali dikhao", "mera lagna kya hai". Calculated by AstroCalc's ephemeris engine (sidereal zodiac, Lahiri ayanamsa). Returns Lagna (ascendant), Moon sign (rashi), Sun sign, nakshatra and pada, the running Vimshottari Mahadasha and Antardasha with dates, the most notable yoga with how rare it is ("1 in N charts"), life areas that are strong or need care, a caveat, and a link to the full free report. Birth details are used only to compute the chart in memory and are not stored. Results are traditional astrology information, not predictions or professional advice.

Discovered
full_chart

The complete birth chart for a detailed reading: Lagna degree; for each planet its sign, degree, nakshatra and pada, nakshatra lord, house, dignity, retrograde status, aspected houses and conjunctions; the 12 houses with lords and occupants; and divisional charts (D9 Navamsa and D10 Dasamsa by default, or any of D2, D3, D4, D7, D9, D10, D12, D16, D20, D24, D27, D30, D40, D45, D60) with vargottama planets. From birth details (free, no sign-in) or for a person saved on the user's AstroCalc account (profile; that needs a free sign-in). Use when a question needs more than the free_kundli summary: a deeper look at career, marriage (7th house, D9), a specific planet or house. AstroCalc calculates; the assistant interprets. Read-only.

Discovered
kundli_milan

Checks how well two people match for marriage in the Indian (Vedic) tradition, from both people's birth details: a score out of 36 with what each of its eight parts means, and whether either person has the Mars placement (Manglik) that families often ask about. Useful when the user is thinking about marriage or a relationship, weighing a proposal or a rishta, or their family has asked for a kundli match: "match my kundli with hers", "kundli milan", "guna milan", "how many gunas match", "kundli milao", "kitne gun milte hain", "rishta aaya hai, kundli match karo", Manglik, Nadi or Bhakoot dosha. Computed by AstroCalc's engine. Returns the Ashtakoota total and band, all 8 kootas (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi) with points and a plain-language meaning, which doshas are cancelled by classical exceptions, each person's Manglik status and the pair verdict, a caveat, and a link to the full free report. Each person needs a birth date and place; time is optional. Details are used in memory only and not stored. The score is one traditional input, not a decision about a relationship.

Discovered
learn_answer

Finds AstroCalc's plain-language guide chapters that answer a general question about Indian (Vedic) astrology, e.g. "what is Manglik dosha", "is 24 gunas enough", "what is Nadi dosha", "Saturn in the 7th house", "how do dashas work", "what is Sade Sati". Useful for general questions that need no birth data, when a source page the user can read is helpful; Hinglish works too, e.g. "Manglik dosh kya hota hai", "Nadi dosh kab cancel hota hai", "kitne gun milne chahiye". Returns up to 3 chapters with title, a short summary paragraph, the canonical URL, and links to the most relevant sections, in English or Hindi.

Discovered
life_timeline

Timeline of life chapters (Vimshottari Mahadashas) and phases (Antardashas, or the finer Pratyantardashas for spans up to 3 years) with start and end dates over a chosen span, marking the one running today. From birth details (free, no sign-in) or for a person saved on the user's AstroCalc account (profile; that needs a free sign-in). Use for timing questions: when a hard period ends, which coming years suit marriage or a career move, what the next decade looks like ("shaadi ka yog kab hai", "agle 10 saal"). Read-only.

Discovered
match_my_profiles

Marriage compatibility between two saved people: the traditional 36-point Guna Milan (Ashtakoota) with all 8 parts and their cancellations, and the Manglik check for both, from their saved kundlis (bride/groom order follows the saved genders). Use when the user asks whether two saved people are compatible, about a match for a son or daughter, or about Manglik dosha between them. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Discovered
my_family_phases

For one saved person or everyone saved on the account: the life chapter they are in now (Vimshottari Mahadasha) and the current phase within it (Antardasha), with dates, plus what comes next and when, sorted by whose phase changes soonest. Use when the user asks why life feels stuck or is shifting, when things will change, what is changing for someone this year, or about timing for family members. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Discovered
my_kundli

Summary of one saved person's birth chart: their nature (Lagna, Moon sign, nakshatra), the life chapter and phase they are in now with dates (Mahadasha / Antardasha), their most notable yoga and how rare it is, and which life areas are strong or need care, with what helps. Use when the user asks about themselves or a saved family member: personality, a child's nature, strengths, what to work on, why life feels a certain way. Same shape as free_kundli, read from the saved chart. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Discovered
my_profiles

List the people whose kundlis the user has saved on AstroCalc (themselves, parents, partner, children, friends): name, gender, birth place, Moon sign, when it was saved, and an id. Use when the user talks about themselves or a family member by name or relation ('my mother', 'my son') and a saved kundli may exist, or asks who is saved. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Discovered
search_place

Finds a city or town and its coordinates, Indian places ranked first, from the same city list AstroCalc's kundli form uses. Useful before the birth-chart, matching or life-phase tools when a place name is ambiguous or misspelled (e.g. "Bombay", "Prayagraj", several towns with one name); pass the chosen label as place, or its lat and lon. Returns up to 5 matches with label, state, country, latitude and longitude.

Discovered
sky_on_date

Planet positions on any date from 1900 to 2100 read against a person's chart: each planet's sign, nakshatra and retrograde status, its house from their Lagna and from their Moon, whether Sade Sati is running, and short notes for Saturn, Jupiter, Rahu and Ketu (positions at 12:00 IST). From birth details (free, no sign-in) or for a person saved on the user's AstroCalc account (profile; that needs a free sign-in). Use when the user asks what is changing for them this year or around a date, whether a date suits a plan, or about Sade Sati or Saturn and Jupiter transits ("Sade Sati chal rahi hai kya"). Read-only.

Discovered
today_for

Today's planetary weather for one saved person, counted from their Moon sign: where the Moon is (and whether it is a Chandrashtama day to go slow), which houses Saturn, Jupiter, Rahu and Ketu occupy for them, and whether Sade Sati is running. Use when the user asks how today looks for them or someone saved, or whether today suits a plan. Read-only. Only for people saved on the user's AstroCalc account (needs a free AstroCalc sign-in); birth details typed in the chat work without sign-in in free_kundli, kundli_milan, explain_dasha, full_chart and life_timeline.

Discovered
yoga_rarity

Says how common or rare a particular combination in a birth chart (a yoga) really is, e.g. Gaja Kesari, Dharma-Karma Adhipati, Hamsa, Malavya, Budhaditya, Kemadruma, Kaal Sarp, Neecha Bhanga Raja yoga. Useful when someone has been told their chart has a special, lucky or worrying yoga and wants perspective: "is X yoga rare", "how rare is my yoga", "Gaja Kesari kitna rare hai", "pandit ji ne Kaal Sarp dosh bataya, kitna common hai". Accepts English, Hindi or Hinglish names ("yog" works too); no birth data needed. Returns "found in about 1 in N charts", the percentage, a rarity label (common / uncommon / rare / very rare), a one-line meaning and a Learn link, from AstroCalc's Monte-Carlo sample of 5,000 Indian birth charts run through its yoga engine. A bare "Kaal Sarp" counts all 12 types together.
