Every CA firm in India knows the feeling: a client forwards an ASMT-10 at 11pm. Demand: ₹8,40,000. Reply deadline: 7 days. You have six other notices on your desk. The draft takes 3 hours minimum — reading the notice, identifying the specific demand, cross-referencing GSTR-2A vs GSTR-3B mismatches, structuring the reply, getting the legal language right.
GSTGuard AI processes the same notice in 60 seconds. Not a template — a full AI draft that extracts the GSTIN, demand amount, notice type, applicable period, and the specific issues raised. Then Claude Sonnet generates a formal reply with proper section references and a CAI self-critique loop that checks coverage and tone before you see it.
What notice types does it handle?
GSTGuard AI handles the eight most common GST notices issued by the department: ASMT-10 (scrutiny of returns), DRC-01 (demand and recovery), DRC-01A (intimation of tax ascertained), DRC-07 (order of demand), GSTR-3A (notice for non-filing), ADT-01 (audit notice), GSTR mismatch notices, and DRC-10 (attachment order). Upload a PDF or plain text copy — the AI extracts all fields with a confidence score (high/medium/low) per field, so you know exactly where to verify manually.
The AI extraction pipeline
Step 1 — Claude Haiku reads the notice and extracts structured fields: notice type, GSTIN, taxpayer name, notice number, notice date, reply deadline, demand amount in INR, the tax period in question, and the specific issues raised. Each field is tagged as 'found' (directly stated in the document), 'inferred' (derived from context), or 'absent' (not found).
Step 2 — Claude Sonnet generates the draft reply. The system prompt instructs it to write in formal CA-standard language, address each issue specifically, cite relevant GST provisions, and not make legal conclusions beyond what the document supports.
Step 3 — The CAI (Constitutional AI) critique loop runs Haiku over the draft, checking only two things: does the reply cover all issues raised in the notice, and is the tone appropriately formal. It never assesses legal accuracy — that stays with the CA.
What the CA still does
The AI draft is a starting point, not a filing. The CA reviews the extracted fields, verifies demand amounts against the client's books, adds case-specific facts and supporting documents, and applies professional judgment before signing. The AI eliminates the blank-page problem and the boilerplate drafting — the CA's time goes into judgment, not typing.
GSTGuard also generates a CA briefing note: a plain-language summary of what the notice is about, what documents to gather from the client, and a deadline tracking view across all active notices.
Real time savings
For a CA firm handling 40 GST notices per month, the math is straightforward. At 3 hours per notice draft: 120 hours/month on notice drafting alone. At ₹500/hour billing rate, that's ₹60,000 of billable time spent on mechanical drafting that AI can handle. GSTGuard costs ₹999/month. The ROI is 60× in month one.
More importantly, the 3am notice from a distressed client — the AI can handle the first draft immediately, so you can send the client a preliminary response the same night and work the details in the morning.
