The Best Mac Menu Bar App for Tracking AI Usage in 2026

If you want a Mac menu bar app that tracks your AI usage live, in 2026 there is one for Claude only (ClaudeUsageBar), one for Claude plus ChatGPT in the same menu-bar item (tokn.watch, free and open source), and a long tail of single-purpose CLI tools and browser extensions that are not menu-bar apps at all. The dual-provider angle is the only thing that meaningfully separates the menu-bar entries; everything else converges. This article picks the best one for each shape of user, with an honest table.

Update, 2026-09-19: Max plans no longer run a separate weekly limit scoped to Opus. Opus and Sonnet are both current, fully available models, and both draw from the single weekly limit that covers every model. The second weekly meter on Max is scoped to Fable instead: Max includes Fable for up to 50% of the weekly limit, after which Fable keeps running on pay-as-you-go usage credits. Pro has one weekly limit across all models and bills Fable from usage credits from the first message. Checked against a live Claude Max 5x account that used Fable, Opus and Sonnet in the same week: Settings > Usage shows current session, this week, and Fable this week, with no Opus meter.

The best Mac menu bar app for AI usage, in one sentence

tokn.watch is the only Mac menu-bar app that tracks both Claude and ChatGPT usage in the same item, and it is free. If you only use Claude, ClaudeUsageBar is the focused alternative and equally good for that case. Everything else worth mentioning is in a different category - browser extensions, CLI tools, web dashboards - and is covered later in this piece.

The reason the recommendation is short is that the category itself is small. As of June 2026, the universe of "Mac menu bar apps that surface your AI usage as a live percentage" has exactly two serious entries. We will spend the rest of this article explaining why those two exist, why the alternatives are in different categories, and which one fits which workflow.

What we mean by "AI usage tracking in a menu bar"

The category is more specific than it sounds. To qualify for inclusion in this comparison, a tool has to do three things at once:

1. Run in the macOS menu bar - always visible, always glanceable, no window required. Not a Dock app, not a browser tab, not a Spotlight launcher.
2. Surface a live usage percentage against the provider's actual rate-limit window - 5-hour rolling session, weekly cap, and so on. Not a token count, not a billing dashboard, not a graph.
3. Poll the provider's own usage endpoint, so the number matches what Anthropic or OpenAI says you have left. Not a local-log estimate, not an API-call counter.

That three-part definition rules out most of the tools you will find searching "AI usage Mac". Browser extensions miss point 1; ccusage and similar CLI tools miss points 1 and 2; OpenAI's own billing dashboard misses point 1 and 3 (it shows API spend, not subscription cap). All of those are useful for different jobs - we cover them later as alternatives - but they are not in the "menu-bar AI usage tracker" category.

The comparison table

Here is the honest grid for the menu-bar category as of mid-2026.

That is the entire menu-bar category. Three apps, two of them serious. The other AI-monitoring tools (ccusage, CUStats, the various browser extensions) are excellent at adjacent jobs but they are not menu-bar apps and are not interchangeable with this list. We cover them in their own section below.

tokn.watch (Claude + ChatGPT in one menu-bar item)

Full disclosure: this is our app, and we are writing this piece. The reason tokn.watch is the recommendation for dual-provider users is structural, not marketing - no other menu-bar app tracks ChatGPT, period, let alone both. If a competing dual-provider menu-bar app launched tomorrow we would update this article and link to them; until then, we are the category.

Functional details: the app is Apple-signed and notarized for the DMG flavour, sandboxed for the Mac App Store flavour, built in Swift with AppKit (no Electron, no embedded browser engine), and the entire binary is under 5 MB. It polls every few minutes by default and the polling interval is user-configurable in Preferences. The app does not collect telemetry; the privacy policy at tokn.watch/privacy covers the full data story.

ClaudeUsageBar (Claude-only, focused)

The honest comparison: on Claude features specifically, tokn.watch and ClaudeUsageBar are functionally close enough that the choice comes down to UI preference and provider coverage. Both read the same Anthropic endpoint, so the percentages converge within one polling cycle. Both handle Pro and Max correctly. Both are free. The decision is ChatGPT or no ChatGPT.

SessionWatcher and the long tail

Beyond these three, the "menu bar" qualifier rules out everything else worth mentioning. Tools like ccusage, CUStats, and claude-usage are excellent at their job (token-level analysis from your local Claude Code logs) but they are CLIs, not menu-bar apps. We cover the full taxonomy of Claude usage trackers, including those, in the complete guide to tracking your Claude usage.

What about browser extensions and CLI tools?

Two adjacent categories come up often when people search for AI usage trackers on Mac. They are worth knowing about because they solve different problems - and because, for some users, they are actually the right tool.

Browser extensions

A handful of Chrome and Firefox extensions surface ChatGPT or Claude usage in the browser toolbar. The most-installed ones in 2026 are ChatGPT Usage Limit Tracker (Chrome Web Store), Token Counter for ChatGPT, and a few less-maintained Claude equivalents. They work by reading the same internal endpoints menu-bar apps poll, but only while the corresponding tab is open.

The trade-off is exactly that "while the tab is open" constraint. If you keep claude.ai or chatgpt.com pinned all day, an extension works fine. If you context-switch heavily, close the AI tab between conversations, or use Claude Code in a terminal where the browser is not involved, the extension goes blind during the gaps. A menu-bar app is always-on; an extension is conditional on browser state.

The full comparison for the ChatGPT side specifically lives in the complete guide to tracking your ChatGPT usage.

CLI tools

CLI tools like ccusage are not in the menu-bar category at all - they parse your local Claude Code log directory and produce a one-shot report on token spend by day, project, or model. They are the best tool for "where did my tokens go this week" type questions, and the worst tool for "how close am I to the cap right now". Different job, different category.

People often run both: a menu-bar app for the ambient signal, plus a Friday afternoon npx ccusage projects for the cost retrospective. The two tools are complementary, not substitutes.

Provider-native dashboards

Anthropic's Settings > Usage page and the /usage slash command inside Claude Code show the exact same numbers as the menu-bar apps, sourced from the same backend. They are free, official, and authoritative. The reason they are not a substitute for a menu-bar app is the friction model: you have to actively load the page or run the command. Menu-bar apps trade a tiny resource cost for ambient awareness.

For users who only care occasionally - a few times a week, when they hit a hard wall - the Settings page is enough and a menu-bar app is overkill. For users who care every day, the ambient surface saves more time than it costs.

Why menu bar is the right surface for this specific job

There is a good reason the menu-bar form factor dominates this category despite browser extensions and CLI tools being technically simpler to build. The decision rests on three properties of the data:

• It changes slowly. Your weekly Claude cap drops by 5-10% in a heavy hour, not by 5% per message. The polling interval can be 5 minutes without missing anything. Slow data is well-suited to ambient surfaces.
• The decision it informs is "should I pace myself". Knowing the percentage at the moment you are about to send the next message is more useful than knowing it after you have already hit zero. Ambient surfaces lead to better pacing; reactive surfaces do not.
• Context-switching is the enemy. If you have to leave your current task, open a tab, click through, see a number, and come back, you simply will not check often enough. Ambient menu-bar surfaces remove that round trip.

This is also why "show a graph" or "show a notification when you hit X%" sounds appealing but does not help much in practice. The right intervention is a number in your peripheral vision, not a chart you have to interpret or an interruption you have to acknowledge. Both tokn.watch and ClaudeUsageBar landed on the same minimal menu-bar UI independently for this reason.

How to decide between tokn.watch and ClaudeUsageBar

If you got this far in the article, you are almost certainly in one of three buckets:

• You use Claude only. Either app works. Pick whichever menu-bar UI you prefer when you see them side-by-side. ClaudeUsageBar's slightly tighter Claude-focused popover is a real plus; tokn.watch's "you might use ChatGPT later" future-proofing is also a real plus. Coin flip.
• You use ChatGPT only. tokn.watch is the only menu-bar option. You could also use a ChatGPT-focused browser extension if you prefer the toolbar surface to the menu bar.
• You use both Claude and ChatGPT. tokn.watch is the only menu-bar app that does both in one item. If you do not want both in one item for any reason, the alternative is running ClaudeUsageBar plus a ChatGPT browser extension simultaneously.

The Claude-only bucket is the only one where the choice is genuinely open. The other two are determined by category, not preference. Anyone telling you the choice is harder than this is either over-thinking it or has an undisclosed angle.

For the underlying mechanics of what each menu-bar number actually represents, see how Claude's usage limits really work in 2026 on the Anthropic side and how ChatGPT's limits really work in 2026 on the OpenAI side. If you are not sure whether you even need to track usage in the first place - which depends on which Claude plan you are on - the Claude Pro vs Max decision guide is upstream of this article.
