Smart India Hackathon submission

Every document hashed.
Every claim traceable.
Nothing accused without evidence.

A secure, multi-case investigation workspace for investigators and legal professionals. Upload the case file and let the platform build the timeline, map the connections, flag contradictions, and draft the report — every conclusion linked back to its source document.

Inside a case file

The whole investigation, charted

Entity breakdowns, conflict severity, upload cadence and evidence-backing scores are computed from the case's own documents — so you can see where the file is thin before you act on it.

How it works

From raw case file to structured report

Four steps, all grounded in the documents you upload — nothing is invented that isn't traceable to a source.

01

Upload the case file

.txt, .md or .pdf. Each document is validated, SHA-256 hashed and logged to the chain of custody.

02

AI reads & organizes

Entities, dated events and factual claims are extracted from every document automatically.

03

Timeline, graph & conflicts

A chronological timeline, an evidence connection graph, and any contradictions across documents.

04

Structured report

A 12-section exportable Markdown report, ready to hand off — with a full audit trail behind it.

Built for the field, not just the demo

One workspace your whole investigating team can actually use

Investigators upload, reviewers verify, admins manage access — everyone works from the same case file instead of scattered folders, group chats and printed reports.

What's inside

Built for the whole investigation, not one document

Every feature below is grounded in the case's own documents and framed as analysis, never as a verdict.

Secure Document Vault

Hash-verified uploads with version and confidentiality tracking, searchable and filterable by type.

Investigation Timeline

Chronological, evidence-linked events with automatic gap detection across 30+ day silences.

Connections graph

People, organizations and locations mapped — click any connection to see the evidence behind it.

Contradiction detection

Conflicting claims surfaced with a conflict type and confidence score — always flagged for human review.

Similar cases

Pattern matches against a reference case library, framed as similarity — never an outcome prediction.

Case chat

Case, Evidence and Legal Knowledge modes, with a Hindi toggle and hold-to-speak voice input.

Role-based access

Admin, Investigator, Reviewer and Viewer roles gate case creation, uploads and deletion server-side.

Audit trail

Every sensitive action on a case — who did it, what it was, and when — in one searchable log.

Exportable report

A structured 12-section Markdown case report, generated on demand and downloadable in one click.

AI Analysis

Case Intelligence

Narrative summary, argument intelligence and grounded case chat — every output traceable to an uploaded document. Conflicting claims now live in their own Contradictions workspace.

No summary yet
Upload at least one case document and this tab auto-generates a narrative summary — every sentence traceable back to its source.
No argument analysis yet
Evidence-grounded potential arguments and fair counterarguments for internal case-building — not a courtroom simulator, and not a verdict.
Verification

Contradiction Analysis

Claims that conflict across the case file, ranked by severity and scored for confidence. Every finding is a prompt for human verification — nothing here is resolved, decided, or treated as proof.

Severity breakdown

Confidence-weighted, highest first.

—

Conflict types

What kind of disagreement was found.

—

Documents most often in conflict

Which exhibits keep turning up on one side of a disagreement.

—
No contradictions checked yet
Once documents are uploaded, conflicting claims across them are surfaced here with a conflict type and confidence score — always flagged for human review, never auto-resolved.
Chronology

Investigation Timeline

Dated events extracted from every document, arranged chronologically and linked back to the exhibit they came from — with automatic gap detection across 30+ day silences.

Event density

Where activity clusters — and where the file goes quiet.
