For people who actually use their AI plans
Claude, Codex, Gemini, Grok: every limit you're burning through, as live fuel gauges in the Windows taskbar. Not a dashboard. A glance.

AI plans come with 5-hour windows, weekly windows, and opinions about when you've had enough. The rules change without notice, too. Headroom watches what your providers actually enforce, so you can stop tab-switching to usage pages.
While you're working it shows one big number: percent left on the meter you're actually burning, from your last-used model's tightest window, 5-hour or weekly, whichever bites first. Idle, it settles into twin bars with your tightest session on top and tightest week below.
An optional strip next to the clock: every account, always visible. Three densities, left or right placement, and it re-anchors itself if Explorer restarts.
Per-account cards with every limit the provider actually reports. Reset countdowns, pace ticks that show whether you're burning fast or coasting, credits and spend where they exist.
Built around one rule: never show a confident number that isn't true.
One warning at your threshold, one at critical. Six-hour cooldown per quota, escalations break through, stale data never notifies.
Signed releases, checked quietly, installed in one click from the flyout. You bought it once. It keeps getting better.
A tick marks where an even burn would put you. One look tells you “coasting” or “burning fast” before the math does.
Multiple accounts per provider. Drag them into the order you think in. The tray, deck and flyout all follow.
Give an API key a monthly budget and spend becomes a draining meter, the same instinct as your subscription limits.
Your credentials never leave your PC. Headroom talks to your providers directly, keys stay in Windows Credential Manager, and your usage is nobody's business but yours.
Subscriptions and API accounts, each read from the provider's own numbers, never guessed from token counts.
New provider adapters ship as updates, and your license already covers them.
Cheaper than the hour you lost the last time a limit surprised you.

Buy once, get a key by email, paste it into Settings → License. One key keeps one device active. Deactivate on an old machine and activate on a new one whenever you like. Every future update is included.
Headroom stops refreshing your meters until you activate a license. Your settings and accounts stay exactly where you left them.
Headroom is a new, independently published app, so SmartScreen may show “unknown publisher” until the installer builds reputation. Updates are cryptographically signed and verified by the app before installing.
API keys go into Windows Credential Manager, not config files. Provider cookies stay inside per-account isolated profiles on your machine. Nothing usage-related leaves your PC except the provider requests themselves.
It's in the works. Buy on Windows today and your license question becomes our problem, not yours. We'll be generous when it ships.
