Stop overthinking your notes. HotJot is the fastest way to capture ideas, photos, and thoughts using an interface you already know: a text thread. Organize your life into Stacks. These are focused, chronological streams of consciousness that feel like texting yourself. Whether it’s a fleeting thought, a photo of a receipt, or a project log, HotJot keeps it organized by time and topic without the heavy feel of other note-taking apps. Why HotJot? • The "Text-to-Save" Workflow: No friction. Just pick a Stack and start typing. • Visual Timelines: Every entry is automatically timestamped. Scroll back to see exactly when an idea struck. • Total Privacy: Your data never leaves your device or your personal iCloud backup. It’s in your control. • Own Your Data: Don’t get locked in. Export any Stack (or your entire library) into a clean .zip file containing universal Markdown files and your original photos or videos. • No ads: We hate ads as much as you do. HotJot is completely free for an introductory period, and if you get it while it's free you'll get upgraded for free later. Perfect for: • Project Tracking: Document progress with photos and quick notes. • Quick Capture: Save links, quotes, book recommendations, and "to-dos" before they vanish. • Personal Journaling: A space for your daily thoughts. • Shopping & Lists: Text your family’s requests into a dedicated Stack.
