Estimate
Four steps. No invoice scraping. No reading your docs.
01
Create a web account. Your password never goes in Chrome.
02
Install the official buildvsbuy.ai extension and enter a code.
03
Type plan name and monthly cost.
04
After enough active days, read KEEP / DOWNGRADE / AUTOMATE.
Plain calls from what we can see in Chrome. We never invent a number like “38% of the plan.”
Keep
Stay on the plan you already pay for. Team tools, or usage that still matches that plan, stay put.
Downgrade
Switch to a named cheaper plan — for example Notion Business → Plus — when Chrome only used features that cheaper plan includes.
Automate
The same sites are opened in a loop (tab A → tab B, again and again). A shortcut may beat another subscription.
Build
Only for small, narrow tools. We show a cost estimate and payback — not a project plan, and not “go build it.”
Pause, export, or delete anytime.
