AITokenMeter — estimated AI token usage & alerts

Description

Estimate token usage on ChatGPT, Claude & Gemini. Set local alerts—no cloud, no official billing. AITokenMeter helps you see how much you are using AI chat — in estimated tokens — while you work in ChatGPT, Claude, and Gemini in your browser. If you juggle several AI subscriptions or long conversations, it is easy to lose track of volume. AITokenMeter adds a simple local dashboard: session totals, today’s total, and a breakdown per provider, so you can stay aware of usage before it surprises you on a bill or plan limit. HOW IT WORKS • Open a supported chat site (ChatGPT, Claude, or Gemini). • After installing or updating the extension, reload that tab once (F5). • Chat as usual — input and output tokens are estimated from visible message text on your device. • Click the extension icon to open the panel, set per-provider alert limits, and watch counters update live. KEY FEATURES • Estimated input, output, and total tokens (session + calendar day) • Per-provider view: ChatGPT | Claude | Gemini • Configurable thresholds with toolbar badge and optional browser notification when a limit is crossed • Export / import JSON statistics for backup on your device • English and Spanish UI; bilingual privacy policy PRIVACY & LOCAL-FIRST • No account required • No upload of your conversations to AI4Context servers • Processing stays on your device; only listed AI chat domains are accessed for metering • You can delete all stored data from the panel at any time IMPORTANT — PLEASE READ Token counts are heuristic estimates labeled “estimated” in the UI. They are NOT official billing numbers from OpenAI, Anthropic, or Google, and may differ from provider dashboards or API usage. AITokenMeter is part of the AI4Context extension family (ai4context.com), focused on transparency and local tools for people who work with AI every day.
