How it works

From signal to decision, with the reasoning visible.

Tarazu runs the whole arc of a product decision. Each step produces something the next one needs — and the last step feeds the first, so the system gets sharper with every call you make.

01 · Listen — every signal in one place

Requests, customer feedback, support themes, research notes, and internal ideas land in one workspace instead of four tools. You can type them in or import a CSV; the importer maps your columns onto Tarazu's fields and routes rows by type, so an existing spreadsheet is a starting point rather than something to abandon.

The point isn't collection for its own sake. A score you can defend needs evidence attached to it, and evidence scattered across three tools is evidence nobody checks.

02 · Score — the same way, every time

Every candidate is scored on four dimensions — reach, impact, confidence, and effort — each on a 1–100 slider. The score recalculates as you drag.

The scoring formula

score = round((reach × impact × confidence) ÷ max(effort, 1))

Tarazu uses a band-based adaptation of RICE on a 1–100 scale. Shared audience, timeframe and band definitions give those numbers meaning. Each score can point to a recorded claim with its actual units and caveats. The result is a relative index, not raw users per person-day or ROI; confidence is an evidence band, not a probability.

Where the AI fits

Tarazu can draft scores for you. Per-candidate suggestions come from Claude Sonnet, using your Strategy Brief, competing candidates, explicitly linked signals, and related recorded decisions. Every suggestion arrives as an editable draft with its reasoning attached.

The AI never scores on its own. A suggestion has to be accepted by a person before it counts, because the value of a prioritization system is that someone is accountable for the call — and you cannot hold a model accountable.

03 · Decide — see the tradeoff before you make the call

The tradeoff map plots every candidate with effort on the horizontal axis and impact on the vertical, splitting the field into four quadrants. Point size can track reach or score; point colour can track confidence or quadrant.

Quadrant boundaries, exactly as Tarazu computes them.
QuadrantEffortImpactWhat it means
QUICK WIN≤ 50> 50Do these first — cheap and consequential.
STRATEGIC> 50> 50Worth it, but plan for the cost.
FILL-IN≤ 50≤ 50Cheap but minor. Fill gaps, don't build a roadmap on them.
THANKLESS> 50≤ 50Expensive and minor. Say no, and record why.

The advisor

One click runs a whole-backlog analysis through Claude Opus. It returns a recommended top priority, the fastest available win, the risk most likely to bite, a suggested sequence, and a strategic read on the set as a whole — each with the reasoning that produced it, so you can disagree with the argument rather than just the answer.

AI requires sign-in and an internet connection. If a request fails or the service is unavailable, Tarazu shows an error; it does not substitute a local recommendation.

04 · Ship — the call becomes a record

A decision is recorded with what you chose, what you chose against, and why. Score changes are kept in history and can be reverted, so “why is this ranked third now?” has an answer that isn't someone's memory of a meeting.

Copy the decision brief into your existing documents or messages. It includes the preserved evidence and caveats, so readers can follow the reasoning.

05 · Review — return with new evidence

Open a decision when its review is due. Record what happened, attach new evidence and choose whether to keep, revise or retire the direction. Each dated review preserves the decision and evidence as reviewed.

Reported outcomes are not independently verified results. Reviews do not rewrite the original reasoning or automatically train the AI. Score edits and recommendation ratings remain available separately for your review.

Who it's for

Tarazu is built for the person who has to defend the roadmap, whatever their title:

  • Product managers running a backlog bigger than a meeting can hold, who need the ranking to survive contact with stakeholders.
  • Founders making sequencing calls without a product org to delegate them to.
  • Product ops trying to make scoring consistent across teams that each invented their own.
  • Platform and infrastructure teams whose work competes with customer-visible features and loses on visibility rather than value.
  • Consultants and fractional PMs who need a defensible artifact to hand a client, not a spreadsheet only they can read.

What you need to start

Requirements

Nothing. Tarazu runs in guest mode with no account: your workspace is stored in your browser's local storage. Sign in for cloud sync, score history, and online AI features. Running AI sends relevant candidate content, Strategy Brief fields, competing candidates, linked signals, and related decision summaries through Tarazu to Anthropic after sign-in.

When you do sign in, workspaces sync to a Postgres database with row-level security, and the Anthropic API key that powers the AI features lives server-side — it's never shipped to the browser.
