Your notes can finally answer you back. IdeaHatch lets you dump rough notes anytime, then ask AI about them — and get the answer you're looking for, instantly. ■ Perfect for - Anyone who takes notes but can never find them again - People who forget the idea they wrote down last week - Indie developers and entrepreneurs with ideas to capture - Writers who struggle to structure their thoughts ■ What IdeaHatch does [Ask AI] "Where's that idea I wrote last week?" "Summarize my notes about X" — just ask, and AI searches your notes to find the answer. Watch the search happen in real time, so you always see what it's basing the answer on. If your question is unclear, AI offers quick-tap options to help you find your answer faster. Not sure what to ask? Suggested questions help you get started. AI can even suggest creating a new note from your conversation. Every past question and answer is saved for you to revisit anytime. [AI-Powered Structuring] Type or speak your rough notes — IdeaHatch's AI reads between the lines and asks smart clarifying questions ("What tone are you going for?", "Who's the audience?"), then transforms your raw input into a well-structured Markdown document that sounds like you. [Markdown Editor + Preview] A capable editor supporting headings, bold, blockquotes, lists, code blocks, and task lists. Tap to toggle between editing and a clean preview at any time. [Voice Input] Speak your ideas and watch them transcribe in real time. Your thoughts, captured at the speed you think. [Export Anywhere] Share as a .md file or export as PDF — ready for Notion, Obsidian, GitHub, or anywhere else you work. [Tags, Bookmarks & Search] Full-text search including tags keeps every note findable. Swipe to bookmark; swipe the other way to delete. [Dark Mode] Light and dark themes available — easy on your eyes at any hour. ■ AI that accelerates you, not replaces you IdeaHatch's AI doesn't think for you. It pulls the information you need out of everything you've written, and amplifies your raw signal. You can always compare the original note side-by-side with the AI version — and every word of the final document is yours to edit. Your ideas deserve to be seen.
