Claude Cost Optimiser 是什么

Chrome 商店介绍

Estimates quota/cost impact of a prompt before it's sent to Claude.ai, with suggestions to reduce cost without losing quality. Claude Cost Optimiser

Estimate the quota cost of a prompt before you send it in Claude.ai.

Claude Cost Optimiser is a free, open-source Google Chrome extension that estimates how much of your Claude.ai usage quota a prompt is likely to consume before you press Send.

Long conversations, multiple attachments, powerful models and high reasoning effort can dramatically increase quota usage. Until now, there has been no easy way to understand that cost before sending a message.

Claude Cost Optimiser helps you make smarter decisions, reduce unnecessary quota usage, and get more value from every conversation.

HOW IT WORKS When you send a message in Claude.ai using Google Chrome, the extension analyses your prompt locally within your browser before it is submitted.

It considers factors including:

Prompt length
Conversation length
Attachments
Selected Claude model
Reasoning effort
Other prompt characteristics that influence quota usage

It then displays an easy-to-understand estimate:

Negligible
Low
Medium
High
Very High
Extreme

...along with an approximate percentage of your available quota that the prompt is expected to consume.

If a prompt looks expensive, Claude Cost Optimiser explains why and offers practical recommendations that can often reduce usage while maintaining similar output quality.

Recommendations may include:

Switching to a more appropriate Claude model
Reducing reasoning effort where it provides little additional value
Splitting large requests into smaller prompts
Removing unnecessary prompt content

Each recommendation includes an estimated saving so you can decide whether the trade-off is worthwhile.

Nothing is changed automatically—you remain completely in control of what gets sent.

PRIVACY FIRST Everything happens locally inside your browser. Your prompts, conversations and attachments are never transmitted to us, to any analytics service or to any third party.

No tracking
No advertising
No accounts
No remote processing

WHAT IT DOES NOT DO Claude Cost Optimiser estimates the cost of an individual prompt.

It does not:

Call Claude or any AI model to generate estimates
Consume any of your Claude usage quota
Track your remaining account quota
Replace a dedicated quota tracking tool
Instead, it helps you avoid wasting quota before each message is sent.

HIGHLY RECOMMENDED For the best Claude experience, we strongly recommend pairing Claude Cost Optimiser with a Claude Usage Monitor extension. The two extensions complement each other:

Claude Cost Optimiser

Estimates the cost of your next prompt
Explains why prompts are expensive
Suggests ways to reduce quota usage before sending

A Claude Usage Monitor

Tracks your overall quota usage
Shows remaining quota and reset times
Helps identify long-term usage patterns

Together they provide a complete quota management workflow: ✔ Know how much quota you have left. ✔ Know how much your next prompt is likely to cost. ✔ Reduce unnecessary usage before you press Send. Used together, they help you maximise every Claude subscription by combining real-time usage tracking with intelligent prompt optimisation.
