Built for whatever you capture
Everyone's ideas are different. A founder's "what if" is a validation problem; a writer's is a lost angle; a manager's is a next step with no calendar slot. Thought Spark runs the same loop for all of them — here's how it shows up in your world.
Same app, four jobs. Find the person below who sounds most like you — each page walks the capture → clarify → research → act loop the way you'd actually use it.
Find your fit
Founders & makers
You have more ideas than weekends. Validate the promising ones fast — prior art, the real gap, sources — then put the first step on your calendar.
For founders →Writers & creators
Your best angles arrive on walks, not at the desk. Catch them by voice in one tap, then turn a raw spark into a sharp, publishable angle.
For creators →Busy professionals
Ideas strike between meetings and vanish. Capture in five seconds, then send a concrete next step straight to Apple Reminders and Calendar.
For professionals →Busy, buzzing minds
Thoughts arrive fast and won't wait. Get them out of your head in one tap — no folders, no filing, nothing to maintain. The app does the organizing.
For racing thoughts →PKM & second brain
You solved capture and storage; processing is still the gap. Add the front door and engine your Obsidian/Notion stack was never designed to be.
For your PKM stack →The one thing they share
Whatever you capture, the failure is the same: a good thought arrives, gets written down, and then just… sits there. No sharpening, no reality-check, no next step. Thought Spark is built to close that gap for all four — see the full loop, or how it compares to other idea and voice-note apps.
Whichever one is you — start free
Capture is always free. Try the loop on your next real idea.
