Build a browser extension and lightweight account service that consolidates subscription prices, plan entitlements, renewal dates, observed usage, and credit purchases across major AI providers. It would warn users before a planned report, research session, or document-processing job is likely to exceed available capacity and recommend the least expensive eligible provider or plan. The first version can combine receipt ingestion, user-entered plan limits, browser-observed usage events, and a maintained catalog of provider pricing rules.

AI providers are combining subscriptions with variable credits, multiple usage tiers, and platform-specific pricing. As professionals adopt several services simultaneously, managing capacity and avoiding interrupted work is becoming a recurring buyer workflow rather than a complaint about one application.
