Traditional CAATs pioneered computer-assisted audit. AI-native platforms are the next evolution. Here's how they compare for Indian statutory audit.
At a glance
Two platforms, opposite ends of the same problem.

Questions
The kind we answer before you ask them.
Absolutely. IDEA, ACL, and CaseWare have been the gold standard for computer-assisted audit for over two decades. They remain deeply embedded in Big 4 workflows, internal audit departments, and forensic investigations. The question isn't whether CAATs are relevant, it's whether your firm needs their scripting power or would benefit more from AI-native automation.
For Indian statutory audit, CORAA covers the analysis CAATs perform, ledger scrutiny, reconciliation, anomaly detection, without requiring scripts. Where IDEA excels is in custom forensic analytics and advanced statistical routines built over years of scripting. If your work is heavily forensic or script-driven, CAATs may still be the better fit. If you need same-day statutory audit automation, CORAA is purpose-built for that.
No. CORAA is designed to be used without any scripting or programming knowledge. You import your data, and AI modules handle the analysis, reconciliation, and working paper generation. This is the fundamental difference from CAATs, where power comes from scripts you build and maintain.
CORAA is primarily designed for statutory audit workflows, the kind Indian CA firms perform under the Companies Act. CAATs like ACL and IDEA have deeper roots in internal audit and continuous monitoring. If your primary need is internal audit with GRC integration, traditional CAATs may be more appropriate. For statutory audit, CORAA offers a faster, more automated path.
CORAA generates timestamped, immutable audit trails automatically, designed from the ground up for NFRA quality reviews. Traditional CAATs produce excellent documentation, but NFRA-specific compliance (Indian statutory format, Schedule III mapping) typically requires additional configuration or manual steps.
There's no direct script migration path, because CORAA doesn't use scripts, it uses AI modules. The analysis your scripts perform (duplicate detection, gap analysis, Benford's law, threshold checks) is handled automatically by CORAA's AI. You don't port scripts; you let the AI replicate the intent. For complex custom forensic scripts, you may want to keep your CAATs licence alongside CORAA.
