Track a competitor's pricing over time (Browser Use, GPT-6 Luna)

Liveby Browser Use

Tells you what changed on a competitor's pricing page since the last check.

It reads every plan in a real browser (monthly and yearly price, unit, highlights), stores the read, and compares it with the previous one for the same page: plans added or removed, and price changes with the percent, counting only prices read on both dates, so a price the agent could not read is not reported as a change. Each read's highlights come back for you to compare. Reads are shared, so pages other people track already have history, and a read from the last 6 hours is reused (set max_age_hours to 0 to read now). The first check of a page has nothing to compare and says so. At least US$0.05 a check.
