Select any statement and get Gemini to verify whether a specific claim holds up, right inside the page you are reading.
Scan an article and have the model call out framing, slant and potential bias so you can read more critically.

Generate balanced, well-reasoned arguments for and against a topic to stress-test your own position.

Locus is an AI-powered browser extension that replaces the traditional Ctrl+F with natural-language search. Instead of hunting for exact keywords, you describe what you are looking for and Locus jumps to the relevant section inside web pages and PDFs, then helps you summarize, brainstorm, and build study notes with LLM assistance.
