From page change to market signal
Competitive intelligence without the manual patrol.
A generic page monitor tells you pixels moved. PlanSentry focuses on the commercial structure of the page—and preserves the evidence behind every alert.
01 · Capture
Build a reliable baseline
Add a public pricing URL. PlanSentry captures its current plans, price points, packaging signals, annual offers, and a private visual snapshot.
02 · Understand
Classify what changed
Separate price moves, plan launches, feature removals, limit changes, and discount shifts from routine page noise.
03 · Act
Route the signal
Review the change feed, compare history, set smart thresholds, or send alerts by email and webhook.
One source of pricing truth
Follow the entire competitive offer—not just the number.
Structured plan intelligence
Turn public pricing pages into a high-level view of detected plans, amounts, currencies, and billing periods.
Package and limit monitoring
Track seats, storage, credits, usage allowances, support, and included features as the offer evolves.
Annual offer tracking
Surface yearly billing, months-free promotions, effective monthly cost, and changes to advertised savings.
Visual and historical evidence
Compare private screenshots, price history, structured summaries, and the underlying added and removed text.
Portfolio organization
Group competitors, add tags, search the portfolio, and compare offers in a consolidated pricing matrix.
Alerts with judgment
Choose severity, delivery cadence, webhook destinations, and thresholds for the changes that deserve action.
