This chapter is part of Gurukul Plus

The foundational curriculum — grahas, rashis, bhavas, nakshatras, dashas and how to read a chart with them — is free to read here and free to practise in the app. Compatibility — Ashtakoota is one of the advanced chapters, and its teaching text comes with Plus.

Plus is ₹199 a month, or ₹1,999 a year. It opens every advanced chapter and raises your saved charts from one to four, so you can work on family charts alongside your own. Both plans renew until you cancel, and cancelling takes one click.

Writing up your experience in the community earns Plus days too — see the subreddit.
