This is one of Briefix's free AI productivity tools. Paste any article, lecture notes, research paper, or homework text - the AI condenses it into clear, shorter text in seconds. No account required. Every feature in the app is 100% free. After summarizing, hit Humanize to rewrite in natural language, then listen with text-to-speech at any voice and speed you choose. Your text is sent once for summarization and never stored. Why I replaced six apps with one free AI tool (Medium).
