You have an idea in your head but no time to sit down at a desk for hours? Capture it on the go, structure it, and find out early whether it holds up. HOW IT WORKS 1. Speak or type it — AI turns it into a clear title and description. 2. Branch and connect — your idea becomes a map you can actually read. 3. Surface the assumptions — AI shows what the idea really depends on. 4. Run the tests — small, guided checks with a deadline, a metric and a target. 5. See the result — passed, disproven, or deadline missed. FEATURES - Capture ideas instantly by voice or text - Turn rough notes into clear wording with AI - Build and branch your idea as a visual map - Generate matching research tasks automatically - Track assumptions with deadlines, targets and a counter - Offline dictation with Whisper or built-in speech recognition - No account required - Available as a subscription or a one-time lifetime purchase On the train, on a break, on a walk: Shliff works whenever you have a moment.
