A research platform answers the question you asked, inside the module you asked it in. You still open a blank document, restate the position in your own words, rebuild the structure of the opinion, and re-key the citations. If the matter touches both GST and income tax, you run it twice and reconcile the two answers yourself.
The same question is reasoned across every module at once, so a cross-border transaction is read under FEMA, income tax and transfer pricing together. The cited position then drafts straight into your firm's own template, branded and ready to send. What you produced stays searchable in the firm's knowledge base, so the next person starts where you finished rather than from the same blank page.
Whichever tool you choose, evaluate it on the things that decide whether the work is defensible: coverage of Indian primary sources; whether the citation is shown verbatim or merely referenced; whether the output is an answer or a client-ready deliverable; whether your own firm templates are supported; whether the knowledge stays in the firm; whether the team can review and sign off inside the tool; and whether the pricing is per-seat or usage-based.
