An App That Eliminates "I Don't Know What to Ask ChatGPT" Choose from 1,033 prompt templates, fill in the dropdowns, and get professional-quality questions in 30 seconds. One-tap paste to ChatGPT / Gemini / Claude / Perplexity / Genspark. --- Why I Built It I wanted people to use AI as a tool for solving small daily frustrations, and as a prescription for reclaiming lost time. Proofreading English emails, deciding tonight's dinner, praising children, getting a second opinion on investments. People are losing a little time and energy every day on small tasks that AI should be able to handle instantly. --- Frustrations with Existing AI Prompt Apps It's incredibly tedious to find a prompt you like. Read the prompt → rewrite it for yourself → copy and paste—most people drop out at these 3 steps. In the end, people just throw vague requests like "make this sound nice" and cry over mediocre answers. This App's Approach Just follow the basic template and tap to select the parts that differ for each user as "variables". No rewriting needed—you get a prompt perfectly optimized for your situation. For example, if you want to know "how to praise my child": → Tap the age (3 years old / early elementary / middle school...) → Tap the scene (extracurricular activities / studying / chores...) → Tap your parenting style (praise to encourage growth / strict approach...) That's it—you get a prompt that fits your situation perfectly. --- What I'm Aiming For Ultimately, I want this to become a "beginner's guide" to AI chat apps. People who installed ChatGPT but never figured out how to use it can use this app as a stepping stone to incorporate AI into their daily lives. That's the bridge-building role I'm creating this for. --- Specs Number of prompts: 1,033 (17 categories / 148 subcategories) Work / cooking / health / investing / parenting / learning / job hunting / SNS / fortune telling, etc. Login bonuses / streaks / referral codes / 14-day free premium Freemium: 51 prompts available for free Tech Stack Expo (React Native) + TypeScript Supabase (analytics / rankings / referral code management) RevenueCat (subscription management) expo-notifications (streak warnings / update reminders via local notifications) --- Since this is an indie project, all feedback, bug reports, and feature requests come through loud and clear. If it sounds like your thing, definitely give it a try.

AA (ASCII art) is convenient when conveying UI images to LLMs (AI). While you could try to convey images visually, that only works with multimodal-capable models. However, with AA, even LLMs with very low parameters can read and understand it. You can convey UI images without being limited by the model type. Plus, with AA, you can make edits in a text editor. No specialized tools are needed. However, creating AA is difficult. That's why I created a tool that makes it easy to generate AA by arranging parts in a PowerPoint-like interface. It supports .md, .txt, and .png output. It has layer separation functionality, real-time preview, and the ability to load and reference images while creating, so I believe it has sufficient performance for practical use.
