A voice journal that only asks once a week. Muse Otter is an AI voice journal built around a single weekly review — not a daily streak you drop by Thursday. Capture by voice during the week, then take 7 minutes to make sense of it. Instead of asking you to journal every day, Muse Otter fits busy lives. Capture quick notes throughout the week by voice, text, or image, then come back for one guided weekly review. The Otter helps turn scattered thoughts into structured clarity. HOW IT WORKS • Quick Notes — Capture thoughts, wins, and challenges in seconds. Voice, text, or image. • Weekly Review — A guided weekly reflection flow to revisit intentions, review your notes, notice patterns, and decide what matters next. • AI Recap Cards — After each review, get a clear recap with themes, patterns, and a visual summary. • Voice-First Capture — Speak when typing feels like friction. Muse Otter helps structure what you capture. WHY MUSE OTTER? Most journaling apps ask for daily consistency. Most people drop off. Muse Otter is built around one intentional weekly ritual that is easier to sustain and more useful over time. The Otter evolves with you: - Weeks 1-2: helps clarify what you captured - Weeks 3-4: starts connecting themes across entries - Week 5+: surfaces patterns and recurring topics FEATURES ○ Quick voice, text, and image notes ○ Guided weekly review with intention tracking ○ AI recap cards with visual summaries ○ Mood and pattern reflection ○ Yearly reflection support ○ Shareable recap moments ○ Smart nudges for unfinished threads PREMIUM Free: 3 notes/week, 2 reviews/month, basic Otter feedback Premium: Unlimited notes, weekly reviews, deeper AI insights, history, sharing, and more Built for people who think deeply but do not want the pressure of daily journaling.
