Prism - Rainmeter

Fetches AI service usage data and sends it to the Prism Rainmeter widget pack.

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. == Supported services == - Claude (claude.ai) - session usage and weekly limits - ChatGPT (chatgpt.com) - message counts - Gemini (gemini.google.com) - active plan detection - Claude Console / API - credit balance and recent spend - OpenAI Platform / API - credit balance and recent spend - 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 == - 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 stored or transmitted - 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.
