Your Ideas Operating System
Capture ideas or opportunities in as few or as many words as you like.
Let AI do the heavy lifting to enrich, research, score and prioritize them.
Quick Setup
Create entries in no time. Give as much or as little detail as you want. Scratch notes or brief summaries are fine.
Single Click Research
Study the value and complexity of your ideas before investing time.
Fast, Frictionless Input
Every action is designed for speed. Clean structure, no clutter, no extra steps.
Capture ideas instantly and keep moving.
Idea Management
Store, rank, and revisit your ideas without losing momentum. Your entire pipeline lives in one organised, lightweight workspace.
Score what actually matters
Evaluate each idea using signals founders actually care about: competitive landscape, monetization pathways and complexity.
Clarity at a glance
Visual rankings and simple summaries replace messy lists and mental overhead.
Prioritise with confidence
Choose what to build next using real metrics instead of gut feel.
Fast, Frictionless Output

Export and integrate seamlessly into your existing workflow.

Tom
Founder of AccretionsI created this platform because I was drowning in half-baked ideas scattered throughout my Notes app with no way to compare or prioritise them.
I needed a clean and simple way to decide what was actually worth building — so I made it.
