Fact-Checking at the speed of live speech

Veraxion extracts check-worthy claims from live speech in seconds, verifies them against official
statistics and global fact-checking databases, and gives your newsroom human-approved
context overlays for live broadcasts.

VERAXION // SYSTEM BLUEPRINT & PRD

< 30s LATENCY TARGET

Real-time claim extraction, normalization, verification, and automated lower-third cueing.

100% DETERMINISTIC DATA

Verifies numeric claims directly against embedded official Indian government snapshots (MoSPI, AISHE, MNRE).

ZERO AUTOMATED RISK

100% Human-in-the-Loop newsroom safety. Nothing airs without explicit producer approval.

HONEST UNCERTAINTY

Never guesses or hallucinates. Explicitly outputs "Unverified in time" when evidence is inconclusive.

500ms EMERGENCY CLEAR

Instant broadcast kill switch clears lower-third overlays in under 500ms with a hotkey.

01 / THE LIVE BROADCAST CHALLENGE

Why modern newsrooms and debate feeds require sub-second deterministic verification.

THE PROBLEM IN LIVE MEDIA

  • Speech Moves Too Fast: Speakers utter dozens of statistical claims per minute during debates and panels.
  • Corrections Arrive Too Late: Fact-checking articles published hours later fail to fix real-time audience perception.
  • Generic LLMs Hallucinate: Off-the-shelf AI invents source figures and risks network credibility on live TV.
  • Cherry-Picked Definitions: Speakers switch between Usual Status vs Current Weekly Status without context.

THE VERAXION SOLUTION

  • Sub-Second Cache: Pre-verified vector matching delivers context in 1 to 3 seconds.
  • Official Data Computation: SQL execution on MoSPI PLFS, CPI, AISHE, and MNRE datasets.
  • Human Operator Desk: "The Wire Desk" interface gives editors 100% control over air graphics.
  • OBS Broadcast Sync: Automatic delay alignment schedules cards at t_spoken + broadcast_delay.

02 / 5-TIER SMART ROUTING PIPELINE

Cascading verification pipeline optimized for speed, compute cost, and strict journalistic accuracy.

TIER 0

Sub-Second Claim Cache

Instant semantic matching against pre-verified claim vectors for sub-second lower-third generation.

TIER 0.5

Published Fact-Check API

Queries Google Fact Check Claim Search and recognized global fact-check organization repositories.

TIER 1

Official Data Snapshot Engine

Executes deterministic SQL queries against embedded SQLite government databases (MoSPI PLFS, CPI, AISHE, MNRE).

TIER 2

Vector Retrieval & Stance NLI

Local FAISS vector search combined with Tavily web retrieval and MiniCheck natural language inference scoring.

TIER 3

30s Graceful Timeout Queue

Automatically flags unresolved claims as "Unverified in time" and routes to human editor triage.

03 / USER ROLES & WORKFLOW INTEGRATION

Dedicated interface views tailored for each member of the broadcast production team.

User Role Primary Screen Workflow Action Value Delivered
Broadcast Operator /console Monitors wire items, inspects evidence, approves overlays Cuts fact-checking triage from 20 mins to 5s per claim
Debate Moderator /moderator Receives short, data-backed follow-up questions on tablet Enables anchors to challenge vague stats live
Broadcast Audience /overlay Views neutral lower-third overlay graphics on delayed feed Builds deep trust without interrupting show flow
Station Executive /results Audits past sessions and SHA-256 evidence logs 100% editorial compliance and auditability

04 / COMPETITIVE COMPARISON

Why leading networks choose Veraxion over manual checking or generic LLM tools.

Feature Manual Checking Generic LLMs Veraxion Platform
Verification Speed 15–60 minutes 5–15 seconds (unreliable) 1–3s (Cached/Official), Max 30s
Live Delay Sync Impossible High hallucination risk OBS Overlay with 30s Delay Sync
Official Data Engine Manual lookup Guesses figures Deterministic SQLite Computation
Air Safety Controls Shouting / Phone Uncontrolled API risk Human Operator Desk + 500ms Kill Switch
Neutrality Standard Subjective tone Unpredictable prompt Neutral Evidence Cards (No True/False Labels)

05 / TECHNICAL SPECIFICATIONS & QUICK START

High-performance zero-build stack powered by Python FastAPI, WebSockets, Deepgram Nova-3, and GLiNER.

06 / FREQUENTLY ASKED QUESTIONS

Q: Where does the landing page redirect users when clicking CTAs?

A: All primary buttons redirect directly to the official Veraxion GitHub repository: https://github.com/VishnupiriyanV/Veraxion.

Q: How does Veraxion prevent false information from airing?

A: Veraxion enforces a strict Human-in-the-Loop design. No graphic appears on screen automatically. An operator must explicitly review the evidence card and click "Approve for Air."

Q: What happens if a claim isn't in official government snapshots?

A: The system routes the claim through Tier 2 vector search and allowlisted web retrieval. If evidence remains inconclusive before the 30s deadline, it outputs "Unverified in time."

Q: How does broadcast delay synchronization work?

A: Veraxion processes undelayed live audio and cues approved lower-third graphics to display on the delayed feed at the exact second the speaker's claim reaches home viewers.
