Look up a word without losing your place .
NotaRead sits quietly in your browser. Double-click a word, get the answer, keep reading. No tabs, no friction, no breaking flow.
Memory is not a recording device. It is a reconstructive process. Each time we recall something, we are not retrieving a file from a folder; we are assembling it anew from fragments of experience, emotion, and expectation.
Definition: Relating to the act of rebuilding something from parts.
In context: Memory doesn't play back; it rebuilds the past each time.
Double-clicked "reconstructive" — NotaRead responded instantly
How it works
Three steps. Zero friction.
You read.
Articles, PDFs, or any webpage. NotaRead stays out of your way until you need it.
You double-click.
A small popup appears. Definition first, context second, translation if you need it.
You keep reading.
Notes are saved automatically. Vocabulary builds itself. The flow never breaks.
Features
Everything you need. Nothing you don't.
Contextual definitions
AI-powered
A dictionary tells you what a word means. NotaRead tells you what it means here — in this sentence, in this author's hands. The AI reads the surrounding text before it answers.
Translation when you need it
30+ languages
One click, not a new tab. Highlight any phrase and translate it into your language without leaving the page. Works with 30+ languages.
Notes that stay attached
Synced across devices
Highlight a passage, jot a thought. It's saved with the source, the page, and the context. Months later, you'll know exactly why you saved it.
PDFs, actually supported
Built-in reader
Most tools ignore PDFs. We built a dedicated reader for them. Open a textbook or research paper and NotaRead works exactly the same as on the web.
Read without installing
Web reader
No extension? No problem. Paste any article URL and read it here with the same instant lookup, translation, and note tools built in.
