The problem
Your SaaS stack is full of assumptions.
buildvsbuy turns those assumptions into evidence.
Stop guessing. Know what to keep.
Your SaaS bill tells you what you bought.
Your browser tells you what you actually use.
buildvsbuy connects those two signals.
01
Pay
Tell us what you’re paying for.
Enter the SaaS, plan, and monthly cost. No finance integration required.
02
Use
Pair your Chrome profile.
The extension measures focused time, app usage, feature signals, and switching patterns.
03
Decide
Get a recommendation from actual usage.
KEEP when you’re getting value. DOWNGRADE when you’re overpaying. AUTOMATE when a loop beats another seat.
Built for one browser profile. Not your entire company.
One Chrome profile. One clear answer.
You don’t need
- ×MDM software
- ×Invoice integrations
- ×Employee monitoring
- ×Page scraping
- ×Complicated analytics
You get
- ✓Focused time on known SaaS
- ✓Feature signals from URLs
- ✓App-switch patterns
- ✓Usage-based recommendations
The SaaS stack gets expensive one renewal at a time.
Then suddenly you’re spending hundreds every month on software your team barely touches.
buildvsbuy helps you find the waste.
Outcomes
Meet your three decisions.
KEEP
You’re getting your money’s worth.
Usage matches the tools and features you’re paying for.
DOWNGRADE
You’re paying for features you don’t use.
Move to a cheaper plan without losing the workflows that matter.
AUTOMATE
You’re paying for a workflow that could be automated.
Spot repetitive app-switching patterns and streamline them.
Privacy
Evidence, not surveillance.
Designed to understand software usage — not spy on people. Data stays focused on one thing: better SaaS decisions.
We collect
Focused time
How long you actively use known SaaS.
Feature signals
Optional coarse feature ids — never full URLs or query strings.
Switch patterns
Repeated app → app workflows.

What people decide with buildvsbuy.ai
Keep, downgrade, or automate — grounded in Chrome usage on one profile, not invented utilization percentages.
Downgrade
“Notion Plus looked essential until the evidence said otherwise — we were living in docs, not databases. Downgraded two seats and the dollar number finally matched how we actually work.”
Keep
“Slack kept coming up as Keep, which was the call I needed before canceling on vibes alone. Focused minutes on this Chrome profile beat another spreadsheet of ‘maybe we use it.’”
Automate
“Jira → ChatGPT → Sheets showed up as a loop every afternoon. The Automate call didn’t invent a product — it just made the wasted context-switching impossible to ignore.”
Privacy
“I only paired my work Chrome profile. No page HTML, no keystrokes — just domains and focused time. That was the bar for installing anything that watches browsing.”
Downgrade
“Loom was on the annual plan out of habit. Usage said we barely opened it. buildvsbuy didn’t scrape invoices — I typed the price once, then trusted the Keep vs Downgrade call.”
Keep
“Figma stayed Keep after enough active days. Useful when finance asks ‘do we still need this?’ and you want evidence from this browser — not company-wide guesses.”
