4. Expanded Feature Catalog (What Astrology Users Ask For)

Each feature is classified: TS / D / X / L. Priority is for the recommended wedge (a Vedic-first AI astrologer that calibrates and remembers, web + WhatsApp, for Indian and Indian-origin users). P0 = v1, P1 = next, P2 = later, — = don't build.

4.1 Onboarding and the chart

Feature	Category	Priority	Notes
Birth details with place search and historical timezone	TS	P0	Wrong timezone history (e.g. India before 1947, war-time DST abroad) gives a wrong chart. Use the IANA tz database.
Accurate Vedic chart engine (lagna, D1/D9, nakshatra, Vimshottari dasha, transits), ayanamsa shown	TS	P0	Test against a reference tool on 200+ charts before launch.
Calibration quiz (8–12 dated, discriminating life-event questions)	D	P0	Rectifies birth time within a window and produces the "it knew" moment. Show what changed and why.
Birth-time confidence meter ("exact / approximate / unknown")	D	P0	Honest about uncertainty. Unknown times get a sunrise or Moon-chart fallback, clearly labelled.
Palm photo scan (entertainment hook)	TS / L	P1	On-device or process-and-discard. Label as entertainment. Don't use it for predictions.
Western tropical chart	TS	P2	A separate audience. Offer later as a toggle, not a second product.
Numerology and name analysis	TS	P2	Cheap to add, popular in India, weak retention.
Tarot, Chinese astrology, I Ching	X	—	Different audiences.

4.2 The conversation

Feature	Category	Priority	Notes
Chart-grounded chat (the model calls the chart engine, never invents positions or dates)	D	P0	The core. Every answer cites the placement, dasha or transit it rests on.
Memory of the user's life (job, relationship, family, past questions)	D	P0	Answers get more specific each week. This is the switching cost.
Hindi, Hinglish and English	D	P0	Most Indian users ask in Hinglish. Add Tamil, Telugu, Marathi and Bengali by demand.
Safety guardrails (crisis routing, no medical/legal/financial instructions, no death predictions)	TS (for survival)	P0	Non-negotiable. See 07.
Consistency (the same question gives the same core answer)	D	P0	Store the "reading" per topic, and let the chat reference it. Inconsistency is how users catch AI astrologers out.
Family and partner profiles (add a spouse's, child's or parent's chart)	D	P1	Progressive profiling. Families consult for each other, which multiplies usage.
Voice questions and spoken answers	D	P1	Many users prefer speaking, especially older users and regional-language users.
Question credits and topic packs (career, marriage, finance, health-as-wellbeing)	TS (monetization)	P0	Matches how Indian users already pay per consultation.
Escalation to a human astrologer	TS in India / L (ops)	— (later, via partner)	Running a human marketplace is a different, ops-heavy business. Partner or refer later if users demand it.

4.3 Daily and timing

Feature	Category	Priority	Notes
Personal daily card (do / avoid, from your transits and dasha)	D	P0	The daily habit. Short and specific. Shareable.
Delivered on WhatsApp (opt-in) and as a web push	D	P0	WhatsApp is where the daily habit already lives in India.
"Favourable window" for events the user plans (muhurat for signing, travel, purchase, puja)	D	P1	The safe version of "important day" alerts. User-initiated.
Panchang, Rahu Kaal, choghadiya, festival calendar	TS	P1	Commodity content, but expected and a good entry point from search.
Transit and dasha-change alerts ("Saturn enters your 7th house next month")	D	P1	Timely reasons to open the app.
"Life timeline" (past calibrated events + upcoming periods)	D	P2	A strong visual. Shareable.
Notifications more than once a day	X	—	Churn and uninstalls.

Feature	Category	Priority	Notes
Compatibility (kundli matching / guna milan) with a shareable result	TS / D	P0	Huge search demand. The shareable result is the viral loop: to see it, the partner enters their details.
"My real ascendant" calibrated card for WhatsApp Status and Instagram Stories	D	P1	Turns the calibration moment into distribution.
Referral credits (free questions for both)	TS	P1	Standard and effective.
Gift a reading	D	P2	Common in India around birthdays and weddings.
Social feed or community	X / L	—	Moderation, and it adds nothing to the one-to-one value.
Dating based on compatibility	X	—	A different, harder product.

4.5 Monetization add-ons

Feature	Category	Priority	Notes
Subscription (monthly, annual) + question credits	TS	P0	See pricing in 07.
Calibrated "life report" as a one-time purchase	TS	P1	Easy upsell after the quiz. Keep it short.
Gemstones, yantras, puja booking e-commerce	L	—	High margin, but fear-based selling of remedies is where the category's trust problems come from, and it adds inventory and logistics.
Advertising	X	—	Low revenue, and it undermines a paid product.

4.6 Net effect

Out of about 40 features, about 14 go into v1. None of them is "a smarter model". They are: an accurate chart, a calibration quiz, grounded chat with memory in the user's language, a personal daily card on WhatsApp, and one shareable loop (compatibility). The product wins by knowing the user, and by being safe enough to keep.
