Saar

About

Saar is an AI usage coach for Claude.ai. It shows you exactly how much you are spending on tokens, how full your conversation context is, and when starting a fresh chat will give you sharper answers.



What Saar shows you:

- Real-time token count and cost for every message you send and every response you receive

- Per-conversation health: healthy, degrading, or critical, based on how much context you have used relative to the model's effective recall window

- Pre-submit estimate: see the token cost of your draft before you hit send, including images and PDF attachments

- Weekly cap usage bar with a projected exhaustion date if you keep your current pace

- For Pro and Enterprise users: month-end spend trajectory with confidence tiers and your top three conversations by cost.



How it works:

Saar runs entirely in your browser. It intercepts the live response stream from claude.ai, counts tokens locally using the official Claude tokenizer, and displays the results in a non-intrusive overlay and a Chrome side panel dashboard. Nothing is sent to any server we operate. There is no backend.



Why I built it:

Platforms that sell compute have no incentive to help you use less of it. Saar is the workflow layer that helps you notice when a conversation is rotting, when an attachment is going to cost more than you expect, and when you are about to blow through your weekly cap.



Privacy:

- All token counting happens in your browser

- No conversation content, identifiers, or analytics are sent to any server we operate

- The extension uses optional host permissions: nothing reads your claude.ai data until you explicitly click "Enable"
- You can revoke access at any time from chrome://extensions

- Full privacy policy: https://getsaar.com/privacy



Permissions in plain language: 

- Storage: persists your settings and conversation history locally on your device

- Tabs: detects which claude.ai tab is active so the dashboard shows the right context

- Scripting: injects the token counter into claude.ai when you grant access

- Alarms: cleans up stale per-tab data

- Unlimited storage: allows conversation history to grow past Chrome's default cap

- Side panel: opens the dashboard in Chrome's side panel 

- Optional access to https://claude.ai: granted only when you click "Enable"
