Beneath the incomplete sentence, there's a word prediction tool suggesting completions like 'name', 'names', 'named', etc. On the right side, the Helperbird extension is active, displaying several features. There's a bright pink 'Helperbird note' that quotes Chef Gusteau from Ratatouille, saying, 'Your only limit is your soul. What I say is true—anyone can cook ... but only the fearless can be great.' Other visible Helperbird tools include 'Voice typing', 'Sticky note', 'Word Prediction', and 'Highlighter'.
