Soliloquy

Soliloquy is a quiet place to keep the words you never want to forget. Found a beautiful word in a novel? Heard one in conversation you'd love to use yourself? Give it to Soliloquy. The app looks it up for you — meaning, pronunciation, part of speech, and an example sentence — and adds it to your own personal library. No streaks. No noise. No clutter. Just you, your words, and a rainy window. A NIGHT SKY OF YOUR OWN Every word you keep becomes a star. Kindred words gather into constellations — wandering minds, westmost hour — drawn just for you across your own night sky. As your collection grows, so does your sky: new stars are born, new figures take shape, and words you've truly learnt shine gold. No two skies are alike, because no two collections are. A LIBRARY THAT IS TRULY YOURS Every word you keep lives in your Sanctuary — a calm, candlelit collection you build over time. Slide along the alphabet to wander through it, mark words as learnt, and watch your vocabulary quietly grow. HEAR EVERY WORD Tap any word to hear it spoken aloud in a warm, natural voice. Choose the voice that suits you and learn the pronunciation properly — no phonetic guesswork required. WORDS WITH STORIES Every word carries a past. Ask for a little story — a three-sentence scene woven around your word, read aloud — or trace its journey: where the word was born, what its roots once meant, and how it wandered through languages and centuries into English. REFLECT, GENTLY A short daily reflection tests you on the words you're still learning. No leaderboards, no pressure — just a quiet moment under your sky. Each reflection strengthens a star; three, and a word is truly yours, shining gold in its constellation. A WORD A DAY Open the app each morning to a new word worth knowing, with an optional daily reminder at a time of your choosing. DESIGNED FOR CALM Soliloquy is navigated entirely by touch — swipe from the home screen to move through the app. Choose from atmospheric ambient backdrops and adjust text brightness to make the space your own. SOLILOQUY UNLIMITED The free version lets you build a small collection, reflect once a day, and enjoy one story and one word journey each day. Soliloquy Unlimited unbinds the sanctuary: unlimited words, unlimited reflections, unlimited stories and journeys, and every voice. Your sky is waiting. Come in out of the rain.
