Compare two items at a time. Statistical algorithms reveal your true priorities. No more agonizing over lists.
You have 20 priorities. Ranking them all at once means juggling 190 possible comparisons in your head. Your brain can't hold that. But answering "which matters more, A or B?" — that's easy.
Around 30 pairwise choices is all it takes to produce a statistically sound ranking.
Paste a list of tasks, ideas, or anything you need to prioritize. One item per line.
"Which is more important?" and "Which is quicker to do?" Just pick one each time.
Terasu calculates the optimal order based on importance and speed. The best ROI tasks surface to the top.

Terasu uses ASAP (TrueSkill) by default — the same algorithm Xbox uses for matchmaking, adapted for priority ranking. It picks the most informative pairs to show you, so fewer comparisons yield better results.
Four algorithms available: ASAP, Glicko-2, Elo, and Bradley-Terry. Each has different strengths — pick the one that fits your use case.
