About the startup
Most good ideas die in a notes app. Thought Spark treats capture as step 1 of 4: capture by voice in seconds (hands-free via Siri), let AI title and file it, sharpen it with a short AI interview tuned to how you think, research it on the web with real sources, and turn it into Apple Reminders and Calendar blocks. Ideas stay on your device. Free to capture forever; Pro unlocks unlimited refining and deep research.
