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 it to desktop widgets, so you can see plan usage limits and API spend at a glance without opening a browser tab. == What's new in 1.3 == - ChatGPT usage tracking: live 5-hour session and weekly limit bars for your Codex usage, the same limits the ChatGPT app shows under "Usage remaining" (shown here as % used). Previously ChatGPT showed plan status only. - ChatGPT plan detection now reads your active account, fixing paid plans that showed as Free. - Cleaner popup: every service and setting now fits without scrolling. == Supported services == - ChatGPT (chatgpt.com) - Codex 5-hour and weekly usage limits - OpenAI Platform / API - month-to-date, today and yesterday spend - Claude (claude.ai) - session and weekly usage limits - Claude Console / API - month-to-date, today and yesterday spend - Gemini (gemini.google.com) - session and weekly usage limits - Google AI Studio - monthly spend, spend cap and tier == How it works == The extension uses your existing browser sessions on each service. You stay logged in as normal; the extension reads the same usage data the website shows you and displays it in its popup. If the Prism widget pack is installed, it also hands the data to a small local helper that writes it to a file the Rainmeter widgets read. == What you need == - A signed-in browser session on each service you want to track. That's all you need to see your usage in the extension popup. - For the Rainmeter desktop widgets: the Prism Rainmeter widget pack and its native messaging host (one-click install via Setup.bat). == What this extension does NOT do == - Your sign-ins are only ever sent to the service they belong to, never to the developer or any third party - No data is sent to third-party servers - No tracking, telemetry, or analytics - Your usage data stays on your machine Open source under GPL v3.
