Know Every Document, Every Version, Every Approval ‍Before a Missing File Becomes a Missed Deadline

A tender document lands in a departmental inbox as a scanned, slightly crooked PDF. Six months later, someone needs to find it — not by its filename, which nobody remembers, but by what it said. "What was the bid submission deadline on that Q3 IT infrastructure tender?" In most organisations, that question means a phone call, a folder search, and a fair chance the document turns up too late, or not at all.With Pi DMS from Pipra Solutions, that search takes a few seconds and returns a cited answer, not a folder listing. The document was OCR'd, classified, and indexed the moment it was uploaded. It carries a full version history, an immutable audit trail, and access controls that respect exactly who is cleared to see it. Nothing about that changes as the organisation grows from one department to a multi-site enterprise — the same platform, the same security model, just more capacity underneath.

One Platform, From Scanned Page to Cited Answer

Government and enterprise organisations share a common blind spot: the gap between a document existing somewhere and a document being findable, trustworthy, and properly controlled. Paper piles up. Scans go unindexed. Versions get overwritten. Sensitive files end up one careless share away from the wrong desk.

Pi DMS, powered by Pipra's AI engine Kuyil, is built to close that gap  a document platform deployable on-premise or in the cloud, where OCR, semantic search, a RAG-based assistant, version control, audit trails, and access control all operate on the same document record, not as bolted-together tools. Here is what each capability does.

OCR: From Scanned Paper to Searchable Record

Pi DMS turns scanned and photographed documents  including legacy paper records, handwritten forms, and low-quality scans  into fully searchable text, in a single ingestion pass.

  • Multilingual OCR — Hindi and English are recognised together out of the box, with the pipeline built to extend to additional languages as an organisation needs them
  • Pre-processing before recognition — automatic deskew and denoising handles tilted, crumpled scans, and contrast enhancement recovers faded or overexposed pages before text recognition runs
  • Confidence scoring per page — low-confidence output is flagged for human review rather than silently indexed as fact
  • No double-processing — pages that already carry a digital text layer skip OCR entirely, so a mixed scanned-and-native PDF is handled efficiently in one pipeline run
  • Optimised for the document types government offices actually generate circulars, file notings, orders, tender documents

Every extracted word becomes instantly searchable the moment ingestion finishes no separate indexing step for someone to remember to run.

Automatic Metadata Extraction and Tagging: No Manual Filing

Documents classify and tag themselves on the way in.

  • AI classifies document type — Circular, Tender/RFP, File Noting, Official Order/Gazette, Archival Record
  • Named Entity Recognition pulls out dates, issuing authority, reference numbers, departments, and signatories automatically
  • Keyword extraction surfaces the top terms for discoverability without anyone typing tags by hand
  • Ready-made schemas for common PSU document types ship with the platform, so most organisations can go live without designing a taxonomy from scratch — and any new document type or field can be added later through configuration, with no code changes required

The result: metadata that would normally require a data-entry step exists the moment the file lands, and it's exposed directly as search filters.

AI Semantic Search: Understanding Meaning, Not Just Keywords

Powered by Kuyil. Pi DMS search goes past exact keyword matching to understand what a query means.

  • Hybrid retrieval — dense vector (kNN) search combined with BM25 full-text ranking, so both conceptual and exact-term matches surface
  • Multilingual by design — a model covering 50+ languages means a query typed in Hindi can return relevant English documents, and vice versa
  • Adjustable relevance — Broad, Balanced, and Precise modes let a user trade recall for precision on any individual search, on top of an admin-tunable default
  • Query shorthand — tag: and file: qualifiers narrow a search inline, combinable with free text
  • Filterable by document type, department, date range, and sensitivity level, with results ranked by relevance score and a matched excerpt preview

Organisations with strict data-sovereignty requirements aren't locked into a commercial API to get this: Kuyil runs fully on-premise, in a private cloud on self-hosted models, or against a commercial API — with no data leaving the network in on-premise mode.

RAG-Based Document Assistant: Ask a Question, Get a Cited Answer

Also powered by Kuyil. Beyond search, Pi DMS lets users ask plain-language questions and get answers grounded directly in the organisation's own documents.

  • Questions and answers work across languages — a user can ask in Hindi and get an answer grounded in an English document, or vice versa
  • Every answer cites its source document — the assistant answers from retrieved content, not open-ended generation, and citations are clickable straight through to the originating file
  • Retrieval is access-controlled — the assistant only surfaces content the asking user is actually cleared to see, so the chatbot can never leak a document the user couldn't otherwise open
  • Follow-up questions carry conversation context, so a user can refine a query without restating it from scratch

Kuyil's model-agnostic architecture means an organisation can start on a commercial API for speed and migrate to an on-premise model later, without changing the application layer.

Version Control and Audit Trails: Nothing Overwritten, Nothing Untracked

Every document in Pi DMS keeps a complete history — of the file itself, and of every action taken against it.

Version control:

  • Every upload and edit creates a new version linked to the same document record — nothing is ever overwritten or lost
  • Full history with timestamp, file size, and checksum per version; the latest version is always one click away, older versions retrievable on demand

Audit trails:

  • Every meaningful event is captured — uploads, views, downloads, searches, tag and settings changes, share activity, sensitivity decisions, logins, and access-denied attempts
  • The log is append-only — no event can be deleted or modified after the fact
  • Every user sees their own trail; full cross-user audit visibility is restricted to elevated roles

When a regulator or an internal review asks who did what to a specific document and when, the answer already exists — it doesn't need to be reconstructed.

Access Control: Configurable Roles, Sensitivity-Driven Access

Pi DMS uses Attribute-Based Access Control, built around two things: who the user is, and how sensitive the document is. There's no rigid, hard-coded role implementation to work around — access is configuration-driven, so an organisation can define its own set of roles and map each one to the document sensitivity levels it should see, matching its existing structure rather than adapting to the platform's.

Sensitivity

Typically Mapped To

SECRET

Most restricted role only

CONFIDENTIAL

Restricted roles and above

INTERNAL

Most internal roles

PUBLIC

All authenticated users

Share links inherit the same cap — a shared link can never grant more access than the sharer's own permission level allows.

Native Document Viewer: Protection That Scales With Sensitivity

Every document opens in Pi DMS's own viewer, and what a user can do inside it depends on the sensitivity of the file itself, not just whether they're allowed to open it.

  • PUBLIC and INTERNAL documents open with normal viewing, download, and print options
  • CONFIDENTIAL and SECRET documents open in a locked-down mode — printing is blocked, the download button is removed from the viewer, right-click and text selection are disabled, and a diagonal watermark carrying the viewing user's email is applied across the page

Sensitivity doesn't just decide who can open a file — it shapes what they can do with it once it's open, enforced by the viewer itself rather than by a separate policy layer.

Compliance and Retention

Compliance is built into the architecture, not bolted on as a report. Documents flagged CONFIDENTIAL or SECRET are held for human approval before they're indexed. Retention periods are configurable by document type and sensitivity, with automatic archival once a document ages past its threshold — and every retention action is logged to the same audit trail as everything else. The platform is designed to align with GoI data handling guidelines, MeitY advisories, and DPDP Act requirements.

Integrations and Workflow Automation

Pi DMS is API-first, so it fits into what an organisation already runs — ERP, CRM, SharePoint, Teams, Outlook, or any system that can call a REST API — with SSO via Active Directory/LDAP and hot-folder ingestion from existing NAS shares. A built-in workflow engine moves documents through Draft → Under Review → Approved → Published → Archived, with the sensitivity approval queue as part of that same flow, and every approval, rejection, or override logged automatically.

Mobile Access and a Personal Workspace

Pi DMS is fully responsive and works identically access control and all on desktop, tablet, or phone, with no VPN needed inside the organisation's network.

My Documents gives every user a single page combining what they've uploaded, what's been shared with them, and everything else within their clearance computed live from their access, not maintained as a manual folder tree.

Live Operational Dashboard

Administrators get a real-time view of the platform without leaving the browser document counts, sensitivity mix, pending approvals, and recent activity, refreshing automatically. An upload, approval, or share action taken anywhere else in the system shows up without a manual refresh.

Performance and Scale

A note on these figures: Pi DMS hasn't yet been through formal load testing. These are engineering projections based on measured component performance, offered as directional guidance for planning not contractual SLAs.

Pi DMS is built to grow with the organisation, without a re-platform along the way:

  • Pilot deployments — a single department or office, comfortably supporting dozens of users and tens of thousands of documents, with sub-second search
  • Regional deployments — several departments sharing one deployment, scaling to several hundred users and a quarter-million documents, with the same responsiveness
  • Enterprise deployments — a headquarters coordinating many sites, built to scale to thousands of users and well over a million documents, with high availability across the platform

Search stays fast at every scale, since only the query itself needs a fresh embedding the corpus isn't re-processed on each search. Documents that already have a digital text layer skip OCR entirely and index in a fraction of a second, so native PDFs move through the system quickly regardless of deployment size; scanned-page throughput is what scales as more capacity is added.

One Platform, Any Deployment Model

Pi DMS deploys on-premise, in a private cloud, air-gapped, or on Kubernetes for high availability the same platform and security model throughout. Document content, metadata, and audit logs stay entirely within the customer's own infrastructure, with no telemetry sent back to Pipra or any third party.

That's the practical point for an organisation evaluating a DMS: the same platform that OCRs a single department's scanned circulars on day one is the platform that, scaled up, serves a million-document, multi-site enterprise without switching products to get there.
