Headroom: AI Usage Limits

Headroom shows how much of your AI subscription limits you have left, for every plan you pay for, in one place. Stop guessing whether you can finish the task before the weekly limit runs out.

Headroom works with Claude, ChatGPT Codex, GitHub Copilot, Grok, Z.AI, Kimi Code, OpenCode Go and JetBrains AI.

One overview for every subscription

Each account shows its weekly or monthly usage, its session usage, and when each limit resets. A big countdown at the top tells you which limit resets next.

Pace, not just percent

A tick on each bar shows where you would be if you spread the limit evenly over the week. Headroom tells you how many points you are over or under that pace, draws the week to scale, and says when you would reach 100% at your current rate. Bars turn wavy only when an account needs your attention.

Reset alerts and reminders

Get a notification when a weekly limit really resets, so you know when you can get back to work. Headroom also reminds you about a day before a usage-limit reset you can redeem expires, so none go to waste.

Usage limit resets

Some providers hand out resets that refill a limit early. Headroom lists the ones each account has, with when they expire, and lets you use Codex, Grok and Z.AI resets from the app.

Widgets for the home and lock screen

Four widget styles, Rings, Bars, Shape and Countdown, each with its own accounts, window and colours. A Quick Settings tile shows the next reset or the quota closest to its limit.

Stats from your own history

See how many resets came without hitting the limit, which service does most of your work, the hours you burn the most quota, and a 7-day line for each account.

Signing in

Each service signs in the same way its own tools do: a browser sign-in, a short device code, or an API key, depending on the service.
