FAQ

Frequently asked questions

Which Claude plans are supported? ⌄
All plans: Free, Pro, Max, Team, and Enterprise. The extension heuristically parses the claude.ai/settings/usage page, so it works regardless of your plan tier.
Will it slow down my browser? ⌄
No. Captures happen in an invisible background tab that opens briefly, grabs the data, and closes automatically. The extension is otherwise completely idle between captures.
How much storage does it use? ⌄
Each snapshot is a small JSON object (~2–5 KB). At 15-minute intervals, 1500 snapshots cover about 15 days and use roughly 3–7 MB of local storage — well within Chrome's limits.
What if the usage page layout changes? ⌄
The content script uses multiple heuristic strategies (ARIA progress bars, percentage patterns, 'X of Y' quota text) rather than brittle CSS selectors. If Anthropic changes the page structure significantly, we'll update the parser and release a new version.
Is this affiliated with Anthropic? ⌄
No. This is an independent, open-source project. It reads publicly accessible data from your own claude.ai account page in your own browser.
