Most of what you'll read today isn't worth your time. The problem isn't you. It isn't your focus, and it isn't your willpower. It's that you're sent more text every day than any human can process, and you've been made to believe you have to read all of it. You don't. You have to choose. Reflex does something other tools don't: it helps you decide before you read. Paste a text, drop a file, send a document. In seconds, you know what it's worth. You're not speeding up your reading. You're sparing yourself the reads that were never worth it. Some texts deserve an hour. Others, two minutes. Many, nothing at all. Reflex tells you which. And when a text does deserve your attention, nine tools are waiting: Summarize. Listen out loud. Translate. Rewrite. Paraphrase. Find synonyms. Correct. Compose. Keep your documents and notes in one place. One tap opens them all. Reflex isn't the Resoomer extension on mobile. The extension serves you when you read what you've chosen, on your computer. Reflex steps in before that: on your phone, facing what arrives without you asking for it. The first helps you read. The second helps you not read. This tool was born in 2016 for one simple reason: to make information reachable for the people a wall of text pushes away. A language you don't fully master. A brain that reads differently. Too little time, too many pages. Years later, it's still the only mission, for our thousands of readers. Free. No account. No detours. You don't have an attention problem. You have too much to read. And now, a way to sort through it.
