Paste text, move through it word by word, sentence by sentence, or in chunks, then use Duck Check to explain what you understood. DuckRead gives AI feedback on what stuck, what needs review, and what to focus on next. When your focus slips, tap I Zoned Out for a quick recap. You can also simplify dense writing into a clearer reading, save reports, and return to previous readings from history. DuckRead is a focus-friendly reading and comprehension tool.
