Free Chrome extension · five AI services

Know your AI limits before you hit them.

Maxoptify reads the real usage meters of your own AI subscriptions and puts them in one popup. Its Pace Index tells you early whether you’ll run out before the reset — not after.

Runs entirely in your browser. No account, no Maxoptify server.

01 — Coverage

Five services, one view.

Each service shows its limits in a different place and format. Maxoptify reads them where they already appear for your signed-in account and lines them up side by side.

02 — What it does

Three things it does well.

Fewer surprises mid-task, without opening five settings pages.

Pace Index

See your pace, not just your percentage.

A percentage on its own doesn’t say much. 60% used is fine with two days left in the window, and a problem with two weeks left. The Pace Index compares how much you’ve used with how much of the window has passed.

Here you have used more than the time that has passed — at this rate you would reach the limit before the reset. The popup also shows a countdown to the reset and the projected usage at that point.

Alerts

A heads-up before the wall, and when it lifts.

Limit alert — when you are approaching a limit.
Burst alert — when usage jumps sharply in a short time.
Reset alert — when a window resets and you can carry on.

Checks run in the background, as often as once a minute while you’re actively using a service and never more than 30 minutes apart.

Floating window & dashboard

Keep it in view, or look back over time.

Pin a small floating window over your work, open the side panel next to a page, or use the dashboard to see usage history across all five services.

03 — Privacy

Private by design.

Maxoptify only needs the usage numbers each service already shows you. Everything else stays out of reach.

No account

Nothing to sign up for. You only stay signed in to your own AI sites.

No server

There is no Maxoptify server. Usage numbers are kept in your browser, on your device.

No tracking

No analytics, no trackers — in the extension or on this website.

Conversations stay private

Your conversations and prompts are never stored or sent. Only usage numbers are kept.

05 — Questions

Common questions.

Why did a tab briefly open by itself?

That is a background check. Maxoptify checks usage automatically, as often as once a minute while you are actively using a service and at most 30 minutes apart. If a service has no open tab at that moment, it opens one in the background, reads the usage figures, and closes it again.

What data does it keep, and where?

Only usage numbers — percentages, reset times and the history that the dashboard draws from. They are stored in your browser on your own device. You can export them or delete them at any time. Maxoptify never stores or sends your conversations or prompts.

Is it really free?

Yes. Every feature is free and there are no plans or tiers. If you want to support the project, there is an optional “Buy us a coffee” link — it does not unlock anything.

Maxoptify is free, with no paid tier. If it saves you from a mid-task cut-off, you can support development with a coffee. It changes nothing in the extension.
