Keep, downgrade, or automate — deciding with usage evidence

The renewal problem

Most SaaS renewals are decided on two weak inputs: the invoice amount and a fuzzy memory of “we use that tool.” Neither answers whether you are using the paid features that justify the plan you are on.

Finance tools excel at showing spend. Spreadsheets excel at listing catalog prices. What they cannot see is how this browser profile actually spends focused time on Notion, Loom, Slack, or Calendly — or which URL-level features show up in day-to-day work.

What buildvsbuy.ai is for

buildvsbuy.ai is a Chrome-based decision tool. You pair a small extension with a web workspace. The extension records coarse usage on known SaaS sites for this profile only: focused minutes, features inferred from URLs, and app-switch patterns.

You optionally confirm plan names and monthly prices. Spend is never invented from list prices. After enough active days, you get plain recommendations — KEEP, DOWNGRADE, or AUTOMATE — with the evidence attached. BUILD appears only as a directional cost sketch, not a project bid.

What it deliberately does not do

buildvsbuy.ai does not scrape invoices, read page HTML or keystrokes, watch desktop apps, or claim company-wide utilization. If a teammate lives in a different browser, that usage is invisible — and that honesty is the point.

A better default question

Before you cancel on vibes or renew on habit, ask: does focused usage on this profile still match what I pay for? That is the question the product is built to answer.
