AI coding tools are amazing — until the bill arrives. A single long agent session, a retry loop you did not notice, or a premium model used for a trivial task can quietly burn through your budget. AI Spend Tracker puts every AI tool you pay for into one clear dashboard. Paste or import your usage, set a budget, and see your spend by tool, project and day — before the month surprises you. 100% local-first. No account, no server, no tracking. Your data never leaves your browser.
