Everything Thought Spark does with an idea
Most apps stop after they transcribe you. Thought Spark takes an idea through a full loop — capture it, clarify it, research it, and act on it — so your best thoughts become real things instead of forgotten notes.
The loop: capture → clarify → research → act. Each step below is its own page — start with whichever problem you have right now.
The four steps
1 · Capture
Tap once and talk, or type. Every idea is transcribed, titled and tagged automatically — no blank page, no friction.
How capture works →2 · Clarify
A short AI interview asks the right questions and turns a vague notion into a sharp, well-formed idea.
How clarify works →3 · Research
Send an idea to the web for prior art, context and risks — and get findings back with real, openable sources.
How research works →4 · Act
Turn findings into reminders, a focused calendar work-block and concrete next steps — straight into your iPhone.
How act works →Why a loop, not just capture?
Capturing ideas is a solved problem — your phone already has three ways to do it. The reason good ideas still die is everything that doesn't happen next: they never get sharpened, never get checked against reality, and never turn into a scheduled step. Thought Spark is built around closing that gap. And because your thoughts are personal, ideas are stored on your device — sent for AI processing only at the moment you use a feature, and never used to train models.
