Pare - AI usage monitor

See what your AI usage costs, by model - tracked privately on your own device. Works with ChatGPT, Claude, Gemini, and more.

Pare shows you how much you're actually spending on AI - across ChatGPT, Claude.ai, Gemini, and the developer platforms you already use - all in one place. Most AI usage is invisible until the bill arrives. Pare watches your browser's AI traffic locally, estimates cost per request using an up-to-date pricing table, and gives you a simple dashboard: spend today, spend this week, and a breakdown by AI model. How it works - Pare reads request and response data for the AI sites and tools you visit, entirely inside your browser. - Costs are exact where the AI provider reports usage directly; for chat websites that don't (ChatGPT, Claude.ai, Gemini), Pare estimates from the length of the conversation and marks these with a "~". - Set an optional daily budget and Pare will flag it in the toolbar and popup when you're close to or over it. Privacy by default All usage data is stored locally in your browser and is never sent anywhere by default. If your employer uses Rein - Dendrons' company-wide AI spend dashboard - you can optionally turn on sync in Settings to share your usage with your organisation. This is off unless you turn it on, and you choose the address and key. Pare does not sell your data, does not show ads, and does not require an account to use. Built by Dendrons (dendrons.ai).
