About

Voice AI Planner

Read full description

An AI planner that lets you capture what’s on your mind just by speaking. Say your to-dos all at once, and AI sorts them into lists for Soon, Later, and Someday. Your plans, feelings, and records of what you’ve accomplished—all on one screen. Created by a developer with ADHD as an AI planner they could keep using in everyday life. You don’t have to keep a perfectly organized schedule. When something comes to mind, just write it down. Completed plans automatically become records, while your feelings and activities are saved alongside them as part of the same day. Things to do right now. Things to do someday. Important things you don’t want to forget. What you’re feeling in this moment. Instead of keeping everything in your head, give each thought a place—and come back to it whenever you need to. -------------------- What is brain dumping? Brain dumping means writing down everything on your mind to help you feel clearer. Sometimes described as a form of meditation through writing, it may help free up working memory and make it easier to process thoughts and memories. Other potential benefits include better focus, reduced stress and anxiety, improved memory retention, and more efficient learning. -------------------- ■ Organize your plans, feelings, and activities in one place • PLANS: What you’re going to do. • THOUGHTS: What you’re feeling right now. • LOG: What you did today. • TODO: What to do soon, later, or someday. The background shifts through morning, daytime, evening, and night at the times you choose. Let the sun and moon accompany you throughout your day. You can also keep your favorite time of day on screen. Your plans, todos, journal entries and other records are stored on your device. AI voice input sends data to external services. HITUKI’s relay server does not store the text content. With HITUKI+, you can access AI-powered voice input, weekly reports, list views, weather, recurring entries, multiple photos, widgets, and more—making everyday life easier to organize. Not to manage everything perfectly, but to get things out of your head and make each day feel a little easier. Whether you have ADHD traits or not, we hope HITUKI can lend a hand in your everyday life. Have a feature request or an idea? We’d love to hear from you. /// Give HITUKI a try! /// Try the annual plan free for 7 days. /// Core features are always free.
