TruthLens is a note-taking workspace that fact-checks your study notes with AI — inspecting every sentence, flagging weak or incorrect claims, and handing back corrections with reasoning and sources. All without breaking your flow.
The mitochondria is the powerhouse of the cell. Water boils at 90 °C at sea level. The Great Wall of China is visible from space with the naked eye. Python is a dynamically typed language.
01 — What it is
Most learners take notes quickly without verifying them, miss subtle factual errors, and spend hours double-checking. TruthLens automates that feedback loop so notes become reliable knowledge.
Inspects every sentence you write and flags weak or incorrect knowledge.
Uses local LLMs via Ollama to verify claims and ground corrections.
Each correction comes with references to trustworthy sources.
Get refined notes with confidence that every claim is verified.
A dashboard to manage documents, view analysis, and track corrections.
User authentication with secure, per-user workspace management.
02 — How it works
Sign up and get your personal workspace.
Create documents and start writing study notes.
Run TruthLens to analyse each sentence for factual accuracy.
See flagged sentences with corrections, reasoning, and sources.
Review and apply suggested fixes to improve your notes.
Maintain a reliable, fact-checked knowledge base over time.
03 — Architecture
A Next.js front end talks to a Django REST backend, which persists to PostgreSQL and calls a local Ollama LLM engine for the actual fact-checking.

05 — What inspired it
"We both go to an international university where professors' first language is often not English — and it becomes incredibly hard to take notes and make sure what you wrote is right." — the TruthLens team
