Description
Highlight any text for an instant AI explanation. Select, click, understand — on every website. One highlight. One explanation. Zero friction. Hilo is a lightweight AI assistant that lives in your browser. No sidebar, no chat window, no copy-pasting into another tab. Highlight a word, a sentence, or a whole paragraph — a small spark appears, you click it, and Hilo explains it right there, in context. How it works 1. Select any text on any webpage 2. Click the spark icon that appears 3. Get a clear, context-aware explanation in seconds Three modes — Explain — concise definition or explanation, 3-5 sentences — Simplify — break it down like you're new to the topic — Translate — translate the selection into your language Context-aware Hilo reads the paragraph around your selection, not just the highlighted words. It knows you're reading about monetary policy when you highlight "quantitative easing" — not just asking for a dictionary definition. Privacy first Hilo never logs what you read or highlight. Selected text is processed and immediately discarded. No history, no user profiling, no ads — ever. Free and Pro Free: 5 explanations/day — enough to try it on anything. Pro: 100 explanations/day, all modes — €2/month or €18/year. Works on Wikipedia, Medium, Reddit, GitHub, news sites, research papers, technical docs, and anywhere else you read online.
