You can find the daily NAVs on the AMC website, most mutual fund markets places or from the Association of Mutual Funds of India.
You can also get this on Jamawealth.com as and when you invest in a specific fund.
One more thing about NAVs. Each mutual fund, has two plans: The Regular and Direct plan. The NAV of both are however different as the regular plan is loaded daily with the broker commissions.
A smart investor always goes for the direct plan, with the help of an investment advisor (like Jamā) who can help you with the investment process, selection, tracking, tagging it with your goals etc.
