PromptLedger

Per-prompt cost and usage tracking for AI creative tools

PromptLedger gives you a clear view of what you're spending on AI creative tools — per prompt, per tool, per project. Runway, Midjourney, and ElevenLabs don't show you a cost breakdown for individual generations. PromptLedger fills that gap by silently tracking credit usage in the background and converting it to a real dollar figure based on your plan. FEATURES • Per-prompt tracking — every generation is logged with its credit cost and dollar equivalent • Dashboard — filterable table of all generations with time-series spend chart and tool breakdown • Budget alerts — set daily and monthly limits per tool; browser notifications fire at 80% and 100% • Project tags — organise generations into projects and filter your history by them • Multi-currency — display costs in USD, EUR, GBP, JPY, and more • CSV export — download your full generation history for your own analysis • Dark mode — full light and dark theme support • Plan detection — visits your billing page to auto-detect your credit rate, or set it manually SUPPORTED TOOLS • Runway (runwayml.com) • Midjourney (midjourney.com) • ElevenLabs (elevenlabs.io) PRIVACY PromptLedger stores all data locally in your browser. Nothing is sent to any server. The extension only reads credit balance information from the tools listed above and never accesses your prompts or generated content beyond what is displayed on screen.
