How it works
Describe your purchase
“I’m choosing between three robot vacuums. What matters: suction, noise, price, and app quality.”
Your assistant builds it
It creates the comparison with your weighted attributes, researches each candidate, and scores them against absolute anchors.
Get a ranked answer — anytime
See the weighted ranking, refine scores as you learn more, and reopen the same comparison in any future conversation.
Why Komparable
AI assistants are great researchers and terrible bookkeepers. Komparable keeps the state and does the math, so the model can do what it does best.
Your attributes, your weights
Define exactly what matters — battery life, comfort, warranty, resale value. Weight each from 0 to 10. The ranking reflects your priorities, not an average of everyone's.
Deterministic, transparent math
Scores are stored and the weighted ranking is computed server-side — the same answer every time you ask, with the formula in plain sight. No regenerated, vibes-based verdicts.
Persistent across conversations
Considered purchases take weeks and many sessions. Your comparison lives under a permanent ID — reopen it next week, on your phone, in a brand-new chat.
Built for AI assistants
An MCP server any assistant can drive. ChatGPT or Claude researches products, proposes criteria, and fills in scores — you just describe what you're shopping for.
