What does Enable AI Analysis do?

When checked, the document is routed through SigmaDSA's AI pipeline on upload. Bank Statement docs get the AI Bank Statement Analyzer (BSA) — transactions parsed, salary detected, EMIs detected, FOIR computed. ID documents (PAN, Aadhaar) get OCR field extraction. Without it the document is just stored as-is.

What does Requires Date Range mean?

For time-bound documents (Bank Statement last 12 months, Salary Slip last 3 months, Form 16 last 2 years), check this — the upload UI then asks for the period. Configure Period Type (Monthly / Yearly) + Past Periods (e.g., 12 months). This drives the BSA's analysis window.

Can I add custom document types beyond the defaults?

Yes — and you should, when your lender panel asks for products the default catalogue doesn't cover (Society NOC, Builder NOC, Probate Order, etc.). Custom types appear in the file's Documents tab and the upload checklist.

How does the document checklist appear on a file?

When a file is created with a Loan Type, the Documents tab shows the relevant document types as checklist items. Each loan type can specify which document types are mandatory vs optional via per-loan-type configuration. Default checklist works for most products out of the box.

Document Types — SigmaDSA Help

Configure the file checklist in SigmaDSA — PAN, Aadhaar, Bank Statement, ITR, Salary Slip, etc. Mark which types need a date range (last N months) and which need AI analysis (Bank Statement Analyzer, OCR).

The Document Types page (/settings/document-types) is the master catalogue of every kind of document the system understands. Each type controls what fields the upload UI asks for, whether AI analysis runs, and how the document surfaces on the file checklist.

Document Types list with Add Document Type button and types table highlighted — The Document Types list: (1) Add Document Type, (2) types table with name, date range, AI analysis, status.

Add a document type

Click Add Document Type

Top-right. A centred modal opens.

Add Document Type modal with form fields and Save button highlighted — Add Document Type: (1) Name + Code + Display Order + Requires Date Range + Enable AI Analysis + Remarks, (2) Save.

Identity

Name — display name (e.g., "Bank Statement"). Required. Shown on the file checklist.
Code — short identifier (e.g., BS, PAN, AADHAAR). Required. Used by API + lender integrations.
Display Order — lower = appears first on the checklist.

Date Range

If the document represents a time period (last N months, last N years), check Requires Date Range. Two more fields appear:

Period Type — Monthly / Yearly / Quarterly.
Past Periods — how many periods (e.g., 12 for "last 12 months").

The upload UI then prompts the user to confirm the period covered, and the AI pipeline uses this window for its analysis.

AI Analysis

Check Enable AI Analysis to route uploads through SigmaDSA's AI pipeline. The pipeline that runs depends on the document name pattern:

Document type	AI pipeline triggered
Bank Statement (or similar)	AI Bank Statement Analyzer — parses every transaction, detects salary credits, EMIs, bounces, computes monthly inflow/outflow. Output lands on the Credit Evaluation tab.
PAN Card / Aadhaar Card / Driving License	OCR field extraction — pulls PAN number, Aadhaar number, name, DOB, address. Auto-fills the applicant card on File Details.
Salary Slip / Form 16 / ITR	OCR + numeric extraction — pulls employer, gross/net amounts, period. Feeds income analysis.
GSTR-1 / GSTR-3B	Tax-return parser — pulls turnover, tax paid, filing date. Feeds GST section on Credit Evaluation.
Other	Stored as-is, no analysis.

Remarks

Free-text note for ops. E.g., "Required for all Home Loan files" or "Only needed if applicant is self-employed."

Click Save

The new document type appears in the loan-file Documents tab checklist immediately (for files of relevant loan types). Configure which types are mandatory for which loan products via per-loan-type configuration.
