FAQ

Answered plainly.

Because free tools give you free results. The AI analysis runs a real API call on every submission. ₹99 covers that cost and signals that this is a product, not a lead magnet. If the tool saves you ₹1,000 in tax, it has paid for itself for the next decade.
Cleartax computes. This advises. Generic tools give you a number. This tool gives you a recommendation, optimisation score, scenario analysis, breakpoint warnings, and a CA-signed PDF — tailored to your persona (salaried, NRI, freelancer, senior).
The AI is prompted with your complete tax profile and instructed to respond as a senior CA at R. Mahesh & Associates. Output is structured: recommendation, Budget 2025 changes, action list, risk notes, and baseline vs optimised. It replaces the first 15 minutes of a CA's advice session, not the CA.
Yes — the Firm tier at ₹2,499/year includes multi-client dashboard, white-label branding, and the ability to embed on your firm's website. Contact mahesh@rmaaca.in for white-label enquiries.
