வணக்கம் · For your parents, in Tamil
சகாயக் தோழன் is a voice-first AI companion in Tamil. One tap and it reads the doctor's note aloud, finds the government scheme they qualify for, flags the scam in a legal notice, and tells today's panchangam.
Live in production - serving Tamil elders today
The engine under the hood
Most astrology apps just reprint stale almanac tables. Sahayak computes the Tamil panchangam, jathagam, and porutham from the real positions of the planets - observatory-grade astronomy, not a lookup. Tithi, nakshatram, yogam, lagnam: correct for your town, to the minute.
Under the hood - for the curious
NASA JPL DE440 ephemeris, read live through Skyfield - the same planetary data used to fly spacecraft, not an almanac reprint.
Sunrise, lagnam and each day's boundaries are computed for your town's precise WGS84 coordinates - never a nearest-city guess.
The Lahiri (Chitrapaksha) ayanamsa, matched to the Swiss Ephemeris to under one arc-second and to the Indian Astronomical Ephemeris.
All five angas - tithi, nakshatram, yogam, karanam, vaara - plus rasi, Tamil masam, and the Vimshottari dasha timeline.
Every rule table cross-checked against DrikPanchang, ProKerala and printed Tamil almanacs, and locked by an automated test suite.

Why we built it
"I built Sahayak for my own parents. They had a smartphone, but the apps, the English, the endless menus - none of it was made for them, so they missed out on everything technology could do. Sahayak is one button, in their language, with the patience to read, explain, and remind. Made by our family, for yours."
