A round-based idea iteration system that treats ideas as competing organisms — scoring, selecting, crossing, and evolving them through structured rounds to surface the strongest concepts.
Most idea management tools are filing cabinets: they store ideas, tag them, and let them rot. Idea Darwin flips the paradigm — instead of organizing ideas, it lets them compete. Every idea is a living species on an evolution island. Each round, the fittest get deepened, different ideas cross-pollinate to produce unexpected hybrids, and external stimuli trigger mutations.
Your ideas are alive on this island. Like organisms, they follow three core laws:
Every idea gets a structured card recording: core question, full description, lineage (parent/child IDs), 6-dimensional scores, and change history.
| Dimension | Weight | What It Measures | |---|---|---| | Novelty | 10% | Genuine breakthrough or repetition? | | Feasibility | 20% | Technically and resource-wise achievable? | | Value | 20% | Impact if successful? | | Logic | 20% | Internally consistent, no gaps? | | Cross Potential | 10% | Can spark something new when combined? | | Verifiability | 20% | Can we design a validation path? |
seed → exploring → refining → crossing → validated → dormantThe user always has final say on all life-or-death decisions. The system only recommends.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +64 percentage points is the difference between those two pass rates over the 22 comparable cases.
The per-case answers from this run were removed by the retention sweep, so the case table below shows the verdicts without the text either arm produced. The counts above were recorded at the time and are unaffected. Answers are now kept for 180 days.
Other measured skills in the registry, with their headline benchmark lift.
