Platform Overview
How SourceLens works.
A privacy-first information intelligence layer built from purpose-driven analysis engines, advanced research workflows, and a local-first data architecture.
Analysis Engines
Credibility Scoring Engine
Produces credibility, evidence, transparency, citation, and depth scores — each with an explanation of why it exists, how it's calculated, and what it means.
Citation Analysis Engine
Detects academic, government, institutional, primary, and secondary sources, then measures quantity, diversity, strength, and independence.
Claim Extraction System
Identifies major claims and maps them to supporting evidence, surfacing potentially unsupported assertions in a claim map.
Source Trust Graph
Builds an interactive graph of authors, domains, organizations, and research sources to reveal citation networks and knowledge pathways.
Bias Signal Analyzer
Browser-side heuristics for framing, loaded language, one-sidedness, and narrative intensity. Provides indicators only — never misinformation labels.
Information Depth Engine
Classifies content from surface-level to research-oriented, with reading commitment estimates and knowledge density scores.
Workflows & Modes
Comparison Mode
Compare multiple articles on the same topic side by side across credibility, citation strength, evidence coverage, bias, depth, and transparency.
Research Mode
An advanced mode with citation trees, reference networks, source lineage tracking, and research-trail discovery for students and researchers.
Knowledge Dashboard
Track articles analyzed, topics explored, research depth, reading patterns, and source diversity — your personal information-consumption analytics.
Achievement System
Earn milestones like Research Explorer, Evidence Hunter, and Knowledge Cartographer. Designed to reward curiosity, not engagement addiction.
Data Architecture
Local-first schemas, stored on your device. You own and control all of it.
