Prism - Rainmeter

Companion extension for the Prism Rainmeter widget pack. Tracks your AI service usage and feeds the data to desktop widgets so you can see plan limits, message counts, and API spend at a glance without opening a browser tab. == What's new in 1.2 == - Gemini usage tracking: live 5-hour session and weekly limit bars, read straight from gemini.google.com/usage (the same compute-based limits the Gemini app shows). Previously Gemini showed plan status only. == Supported services == - ChatGPT (chatgpt.com) - message counts - OpenAI Platform / API - credit balance and recent spend - Claude (claude.ai) - session usage and weekly limits - Claude Console / API - credit balance and recent spend - Gemini (gemini.google.com) - session usage and weekly limits - Google AI Studio - quota tracking == How it works == The extension uses your existing browser sessions on each service. You stay logged in normally; the extension reads the same usage data the website shows you, then forwards it to a small native helper that writes it to a file the Rainmeter widgets read. == What you need == - Technically this extension doesn't require anything. If you want to monitor your usage just from this extension in Chrome, this is all you need. Otherwise if you want the Rainmeter desktop widgets then you need: - The Prism Rainmeter widget pack installed - The native messaging host (one-click install via Setup.bat) - An active session on whichever services you want to track == What this extension does NOT do == - No credentials are sent to any server or third party - No data is sent to third-party servers - No tracking, telemetry, or analytics - All data stays on your machine Open source under GPL v3. Source code, installation guide, and the full Rainmeter widget pack are on GitHub.
