A connected GST workflow system. Not a generic AI chat tool.
GSTArk™ is an integrated GST workflow, decision intelligence and drafting system. Every output is structured, editable and source-aware. Users select a bench, apply built-in expert logic, and receive a legal-grade draft — not a prompted text block.
Integrated GST workflow benches
Structured benches for scrutiny, audit, inquiry, SCN, OIO, review, recovery, refund, registration, appeal and GSTAT. Users never start from a blank prompt.
Built-in expert prompts
Every card carries built-in GST expert prompt logic. Dropdowns change the legal posture and output package. No prompt engineering required.
Editable A4 legal drafts
Outputs arrive as A4 legal draft previews — edit, add custom instructions, save versions, copy or export. Not generic chat output.
Decision intelligence
Built-in analysis of limitation, natural justice, mens rea, evidence sufficiency, litigation risk, appeal sustainability, document gaps and source confidence.
Financial analysis integration
Generate financial analysis reports with exposure, reconciliation, variance, risk and document proof layers. Legal workflow can directly use financial findings.

Department-side notesheets and internal notes for review, revision, appeal, recovery, audit and PH stages — built into the drafting workflow.
Portal summary intelligence
Full speaking SCN with DRC-01 summary, full speaking OIO with DRC-07 summary, and DRC-08 rectification summary — separate from and complementary to full legal drafts.
GSTAT litigation workflows
Dedicated GSTAT filing package: APL-05 / APL-06 / APL-07 logic, IA / stay / condonation / written submissions. No DRC-07 in GSTAT — correctly handled.
Verified source layer
Acts, rules, forms, circulars, notifications, instructions, judgments, manuals, GSTAT rules, case records and guidance — missing authority flagged as source verification required.
Revenue and taxpayer workflows. Separate. Connected. Structured.
GSTArk™ does not mix revenue and taxpayer workflows. Each mode has its own structured benches, built-in expert prompts and output package logic — matched to the legal posture and stage of the matter.
Department-side workflows
Structured GST benches for revenue officers — from scrutiny and audit through SCN, OIO, review, recovery and GSTAT, with notesheet and financial analysis support.
Defence and appeal workflows
Structured GST benches for taxpayers, CAs, advocates and consultants — from reply and hearing through appeal, GSTAT, refund, registration and financial reconciliation.
Select bench. Analyse position. Generate draft. Edit and finalise.
GSTArk™ is a connected output system. Each step feeds the next — from bench selection through decision intelligence to editable A4 output. Users do not prompt. They select, review and refine.
Select Bench
Choose the matter type from structured GST workflow benches — scrutiny, SCN, OIO, audit, appeal, GSTAT, refund, registration, recovery or financial analysis. No blank prompt.
Analyse Position
Add facts and upload records. GSTArk™ applies built-in expert logic — limitation, natural justice, evidence sufficiency, mens rea, litigation risk, source confidence and document gaps.
Generate Draft or Report
Receive an editable A4 legal draft, notesheet, financial analysis report or portal summary — depending on the bench and output type selected.
Edit and Finalise
Edit the draft with custom instructions, save versions, use portal summary where applicable, and export or copy when ready. Output is always in your control.

Start 7-Day TrialInstitutional legal intelligence for GST practice.
GSTArk™ was built by former CGST officers, practicing advocates, and GST litigation specialists who recognized that GST decision-making requires access to verified legal intelligence, not just document drafting.
After 12+ years of GST practice, we observed that officers, professionals, and taxpayers struggled with three core challenges: understanding complete GST positions, evaluating litigation sustainability, and preparing defensible actions backed by verifiable evidence.
GSTArk™ is our response. A GST intelligence infrastructure platform that combines verified legal research, procedural analysis, pattern intelligence, and appellate awareness into one unified system. Every recommendation is evidence-backed, every position is citation-linked, and every risk assessment is grounded in legal precedent and procedural requirements.
We believe GST professionals and officers deserve better than guesswork. They deserve intelligence. Verified, evidence-backed, actionable intelligence.
Our Principles
Every legal reference verified against primary sources.
No arbitrary outputs. Citations, reasons, and confidence scores visible.
Users understand exactly why a position is strong or weak.
Every action recommended is sustainable in appeal or litigation.
Combined experience of founders in adjudication, litigation, and compliance.
15,808 verified case law records • 3,232 AAR/AAAR rulings • 1,221 notifications • 240 circulars • 195 forms
Every recommendation linked to verified sources and legal authority.
GSTArk™ provides structured intelligence, not unverified legal conclusions.
