Capture your thoughts as they come, then hand them off to AI—keeping what matters most close at hand. ◆ Just Toss It In ・Just speak into the mic. When you're done, simply say "Send it" and let AI take it from there. ・No need to organize your thoughts or find the perfect words. ◆ AI Sorts It Out ・The Tidy Assistant automatically sorts your thoughts into four simple categories: Lighten Now, Later, Grow, and Let Go. ・Whether it's plans, shopping lists, or random ideas, AI puts everything in the right place. ◆ Consult External AI ・Pass your collected thoughts to ChatGPT, Claude, or Gemini to hear AI's perspective. ・Bring AI's responses back into the app to record a clearer, more authentic picture of who you are today. ◆ Display What You Love on Your Shelf ・Keep the videos, music, and books you discover online alongside your favorite vinyl records. ・Just paste a link, and Head-Light turns it into a nostalgic cassette-style cover or card, beautifully arranged on your shelf. ◆ A Journal That Grows Effortlessly ・Your spoken words and snapped photos naturally become each daily page, letting you flip back through your past like a photo album. ◆ Useful Tools to Support Your Life and Mind ・Medication and sleep logs ・AI assistants for expenses and meals ・Daily mood tracker with visual charts ・Various timers for Pomodoro, workouts, meditation, and more ・Custom routines with timed tasks, voice guidance, songs or Apple Music playlist links, reminders, and streaks ・Idea and venting jars Customize your home screen with only the tools you need. ◆ Your Records Are Yours. ・No Ads.
