Hilo - AI Explain, Simplify & Translate Highlighted Text

Select any text to explain, simplify or translate it with AI, right next to what you're reading. Free 5 a day.

Read anything. Understand everything. Select any word, sentence or paragraph on a web page and Hilo explains it right next to the text: its meaning in context, a simpler version, or a translation. No sidebar, no chat window, no copy-pasting into another tab. 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, with a "Go deeper" button when you want more - Simplify: break it down like you're new to the topic - Translate: translate the selection into your language Context-aware Hilo takes context from around your selection and from the page, 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 stores what you read or highlight. The selected text is used to write the explanation, then discarded; the server keeps a daily usage counter, not your text. No history, no profiling, no ads. Free and Pro Free: 5 explanations/day, enough to try it on anything. Pro: 100 explanations/day for €2/month or €10/year. Works on Wikipedia, news sites, research papers, technical docs, and anywhere else you read online.
