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.

I found this very useful since I overuse AI most days. It helped me to control how much quota I use, prolonging my use of AI.

Really useful extension if you use Claude regularly. It's nice being able to see an estimate of how expensive a prompt is before sending it, especially when working on longer conversations or uploading files. I also like that it explains why something is likely to use more quota and suggests ways to reduce it instead of just giving a score. Everything runs locally too, which is a big plus from a privacy perspective. Simple idea, but genuinely helpful.
