Step-by-Step Instructions

chrome://extensionsFor Edge, use edge://extensions • For Brave, use brave://extensions • For Opera, use opera://extensions

Toggle the "Developer mode" switch in the top-right corner of the Extensions page. This allows you to install unpacked extensions.

Quick Questions
Can I install on multiple browsers?
Yes. Repeat the installation steps for each Chromium browser (Chrome, Edge, Brave, etc.). Your settings are stored independently per browser.
Will updates happen automatically?
Not yet. Since this is a developer preview loaded via "Load unpacked," you will need to pull the latest code from GitHub and reload the extension at chrome://extensions.
Do I need a backend server?
Yes. TruthLayer requires the backend server to run locally on your machine. After cloning the repo, open a terminal in the backend/ folder, run npm install && npm start, and keep it running while using the extension. The backend handles AI analysis and trust score calculation — it is not hosted remotely. This is a developer preview; a cloud-hosted version is planned.
Is my data safe?
Yes. TruthLayer only sends structured metadata (page title, headings, tracker domains) to the API. Raw page content stays in your browser. No personal data is collected or stored.
