A product decision you can return to.
Tarazu connects a choice with its evidence, tradeoffs and next test, then keeps dated reviews alongside the original reasoning.
Why it exists
A ranking answers which option came first. It may take more work to explain why, especially when someone returns to it months later. Tarazu keeps the choice, source notes and later reviews together.
Use RICE to compare options, check the sources behind a score, and save the next step. Spreadsheets and other discovery tools can also keep this context; Tarazu gives it a place in the decision record.
What it isn't
It's not a roadmap tool or a project tracker, and it doesn't make the call for you. The AI drafts a score; a person decides whether to keep it. Where it stops is on purpose — a ranked list and a written-down reason is the handoff to whatever you actually run delivery in.
Who built it
I'm Kristen Martino, an Product manager with a Master's in Business Analytics from UT Dallas. I built Tarazu to keep product decisions connected to their evidence, assumptions and reasoning.
Writing the PRD before touching the backlog UI was slower than it needed to be, but it's also the reason the scoring model, the AI, and the tradeoff map agree with each other instead of pulling in three directions. That PRD, the competitive research, and the launch plan are still in the repo.
The source is on GitHub if you want to see how any of it works.

The name
Tarazu (तराज़ू / ترازو) is the Hindi and Urdu word for a balance scale, from the Persian tarāzū. A scale doesn't decide anything — it shows you which side is heavier and leaves the rest to you. That's the whole design philosophy in one object.
How it works covers the full loop end to end, and the RICE guide gets into the scoring model, including where it breaks down.
