Extension changelog

A notification the day Anthropic releases a new Claude model, with its API price per million tokens, on every plan, Free included. One per model, and you can turn it off in Settings › Notifications.

A banner in the popup when a new model comes out, with its API price and a link to every Claude model on usagemeter.app.

Pro alerts before the wall: at your threshold (90 % by default), when your current pace would block you soon, at 100 % and the moment a limit is back, even if it reset while your browser was closed. Never twice for the same alert, across your browsers and the UsageMeter Link app. Turn on a heads-up the day before your weekly reset when much of your week is still unused.

“At this pace: blocked around 21:40”: the forecast now follows your last 45 minutes (12 hours for the week), in the popup and in the toolbar icon's tooltip.

The price of every reply on claude.ai: what it cost your session (“+1.8 %”), under the reply and in the message box. When Claude Code or another chat moved your limit at the same time, it shows “≈” or nothing, never a wrong figure.

Claude widgets for your GitHub README: your Claude Code tokens, a GitHub-style grid of your days with Claude and your streak, and your models, as cards or shields.io-style badges, for your profile, your site, Notion or Obsidian. Nothing is public until you switch it on, and one click turns it all off. Six widgets, including the new trophies, and six themes are free, with corners, border, size and a compact form. Pro adds the Claude Code cost and all-in-one stats cards, 13 more themes (Dracula, Nord, Tokyo Night…), your own colours and up to 52 weeks on the grid.

When Claude is down or overloaded, the popup and a pill under the claude.ai message box say so (“Incident at Claude, not your limit”), with a link to the status page.

Free Claude accounts get their gauges: UsageMeter reads the limits Claude sends with each reply.

Today's budget: “Today: 8 / 12 pts” spreads what's left of your week until it resets, with a timeline of your 5-hour window, and your resets go to Google Calendar, Outlook or an .ics file in one click.

“Share my week”: a button in “This week by product” opens your shareable card on usagemeter.app.

Claude Code routines: today's runs next to your limits (“9/15”), on claude.ai/code/routines too, with a Pro alert at 80 %.

UsageMeter in the side panel, an optional two-ring toolbar icon (session and week), and Alt+Shift+U to open it. The popup now fits any width.

Firefox for Android is supported.

Blocked on claude.ai? Pro asks for a reminder at the reset (“Remind me at 6:49 PM”) right from the panel, the toolbar badge alternates MAX with the time left, and a “What can I do?” link explains your options.

An attachment's weight before you send it (“report.pdf ≈ 38k tok · ~4 % of session”), worked out on your device.

Paid plans get a reminder of the limit reset Anthropic gave with Opus 5.5 (to use before October 22, according to press reports), with simple advice when Claude reports it.

On the free plan, History shows your real chart, blurred and computed on your device. Pro adds the chats that weighed most on your week.

Updates install by themselves within minutes and your claude.ai tabs keep working: no more red “reload” message. After an update, one sentence tells you what's new.

Every Pro offer shows the monthly and the yearly price with the real saving (nearly 2 months free), and the Pro links on claude.ai open the pricing page.

Easier to read and to drive from the keyboard: stronger contrast, 1 to 5 switch tabs, R refreshes, and a small “?” opens the guide for the lines people often misread.

The message queue works again, speaks your language and shows in the toolbar tooltip instead of replacing the badge; “MAX” no longer shows at 99 %, German durations read “2 Std. 13 Min.”, and plans are named “Max 5x” and “Max 20x” everywhere.

A new popup that counts in tokens. Every Claude limit gets its own gauge: the 5-hour session, the weekly limit shared by all models and products, and any separate weekly limit a model or product has. Each one tells you whether you are on track or roughly when you would hit it at your current pace. The old "messages left" estimate is gone.

This week by product: see how much of your weekly limit went to chats, Claude Code and Cowork. Pair the UsageMeter Link companion app and the Claude Code share turns into real token counts, added up across all your PCs.

Usage credits at a glance: if you pay for usage past your plan limit, the popup shows this month's spend against your monthly cap, what you can still spend and whether auto-reload is on.

Interactive charts: your usage over the current window with a projection to its reset, over the last 24 hours or over the last 7 days. The arrow keys move along the curve, any chart can switch to a table, and the CSV export keeps every point.

A "Closest limit" option for the toolbar badge: the icon shows whichever limit is nearest to blocking you.

A new setup after install, in five short steps: your live usage straight away, then your look, what the extension does, an optional account and Pro.

Upgrade to Pro in one click from claude.ai. When the extension is signed in, Pro switches on by itself right after payment and an open popup updates on the spot.

UsageMeter now starts in your browser's language, and a language picked in Settings applies instantly.

Restore from account now tells you what happened: settings restored, nothing new to bring back, or server unreachable.

The welcome offer is now translated into all 34 languages; 32 of them used to show it in English.

Signing in on a second browser no longer erases your saved Claude accounts. Accounts are now merged between browsers: each browser keeps its own session keys and what it measured, and the latest rename of an account wins everywhere.

A browser that signs in to your account for the first time now gets the settings of your other browsers straight away.

Turning keyboard shortcuts off, or back on, now takes effect immediately, without reloading claude.ai.

The setup no longer promises a free first month once the welcome offer has ended: it shows the 7-day free trial every new subscriber gets.

Join the UsageMeter Discord and get 1 month of Pro free. The invitation appears once when you open the popup, and the link stays available under Settings › More › Discord community.

Promotions no longer stack: the Discord invitation and the Claude Code companion card never show together in the same popup session.

The popup now shows tokens right under "Messages left", every time: roughly how many tokens of your 5-hour window you have used, out of how many it holds. It no longer waits for a solid estimate — a rough figure appears from your first measured message, or right away when you are signed in — and hovering it tells you where the number comes from.

The estimated token limit for your Claude plan, pooled from other UsageMeter accounts on the same plan, now appears as soon as one of them has measured it. It used to take five accounts, which left most plans without any figure at all.

The Claude Design usage indicator is gone. Claude Design no longer has a limit of its own, so its setting under "On claude.ai" and the usage chip on the Design page have been removed.

The extension is now listed as "Claude Usage Meter" — in two words — in the Chrome Web Store and on Firefox Add-ons, so it comes up when you search for "usage meter".

The welcome offer now shows its real price. The setup page and the popup say what the WELCOME code actually does — your first month of Pro is free, then the regular price — instead of a confusing discount line, with a 24-hour countdown for new installs. "See Pro" opens the pricing page with the code already applied.

Prices in your own currency: US, Canadian, Australian and New Zealand dollars, pounds, Swiss francs, yen, won, rupees, reais, pesos, złoty, kroner, koruna, Singapore and Hong Kong dollars. Detected from your time zone, switchable on the pricing page, and the checkout charges exactly the amount you saw.

The extension is now listed as "Claude UsageMeter" in the Chrome Web Store and on Firefox Add-ons, so it comes up when you search for Claude.

Exporting a conversation to PDF no longer pulls in an 800 KB library on the first click — the extension now builds the file itself. Same page layout, a much faster first export, and a lighter extension for everyone.

Characters a PDF cannot draw — Chinese, Japanese, emoji — used to come out as unrelated Latin letters. They now appear as a question mark, and arrows or comparison signs are written out (-> and <= / >=) instead of vanishing.

Themes, backgrounds and fonts have moved to the bottom of Settings. In 1.4.11 they sat right under Language, and three screens of theme cards buried the meters, the on-page toggles and the tools. Everything you actually open Settings for is back within reach, with the whole Style section still one scroll away — no sub-menu.

Themes, backgrounds and fonts are directly in Settings, right under Language. They used to hide behind Settings → Appearance → Themes ›, one screen too deep for most people to ever find.

The Chat width option (Default / Wide / Maximum) is gone, from the settings and from the setup tutorial. Claude's redesign lays the conversation out itself; a stored Wide or Maximum is no longer applied.

"Messages left" finally shows a number. It could sit on "— calibrating" for weeks: the estimate was worked out once when the popup opened, before your usage had finished loading, and was never worked out again. On top of that, accounts whose usage page updates slowly recorded no measurements at all, and very small per-message costs were rounded down to zero. All three are fixed, the row now shows how far calibration has got ("2/5"), and it updates live as you send messages.

You can import an account key without being signed in to Claude. If you were signed out, the extension showed a connection error with no way past it — the tabs were hidden, so Accounts was unreachable. The tabs stay available now, the error card links straight to the key import, and importing a key while no account is connected signs you into that account right away.

Keys exported by older versions can be imported again. Anything exported before the UsageMeter rename was rejected as "invalid key format".

The "?" bubble in the popup header is now a "Sign in / Sign up" button, so it is clear what it opens.

Token estimates and the conversation counter next to the composer are on for everyone and no longer have switches — they are part of the extension now. Same for cloud sync, which also carries more of your setup: your on-page preferences, provider choices, saved prompts and your measured calibration now follow you to another browser. Feature toggles were being sent to the server and quietly discarded, so they never followed you anywhere.

The setup tutorial ends with a plan step: what the free version does, and Pro with 30% off the first month using the code WELCOME.

Settings → Delete my data, and a privacy page on your account where you can ask for a copy of everything we hold about you, or for its deletion. Each request is confirmed by a member of the team before anything is exported or erased — a safeguard against a stolen session wiping an account — and you are emailed at each step.

The privacy policy has been rewritten from scratch and now lists every piece of data, why it is collected and how long it is kept. The extension no longer fingerprints your browser: the device identifier used to be derived from a canvas drawing and your graphics card, and is now simply a random number.

Translations completed in all 34 languages — roughly 280 texts that were still showing in English, including the whole colour editor and theme manager.

The usage percentage stays in one place. Claude's redesigned composer fades its "Claude can make mistakes" notice and the model name in and out of the same spot, and the usage chip was riding along with them — sitting on the far left in some conversations, sliding sideways as the two swapped, and disappearing altogether in others. The chip, the conversation counter and the export buttons are now pinned to the right-hand end of the bar under the composer, in the same place in every chat.

Only one Accounts button in the sidebar. Switching between Claude Code and a conversation added a second, identical button next to the first — Claude's new interface uses a single shared sidebar for both, and each one was being filled in separately.

Claude's own disclaimer under the composer is left alone. The usage chips now sit next to it instead of taking its place, so nothing of Claude's interface is hidden to make room for them.

The one-off "UsageMeter Link" announcement no longer opens over the extension popup. The companion app is still one click away from the Usage tab.

Themes paint claude.ai again. Claude's redesign moved every colour onto a new token set and started loading its own stylesheet later in the page than ours, so all 56 themes silently stopped applying — the page just stayed grey whatever you picked. Themes, custom colours and the gradient presets all work on the new interface.

The toolbar under the composer no longer climbs on top of the input box. Claude's new disclaimer bar is built with a negative offset that the toolbar was cancelling out, which buried the usage chips behind the composer, pushed the composer past the bottom of the window and left the conversation unable to scroll to its last messages.

Settings stop reverting on their own. A version counter that never advanced let the server hand back old values over settings you had just changed — most visible right after a fresh install, where the first things you configured came back wrong.

"Chat bar: ring + tools" showed as OFF in Settings while the feature was actually ON, so switching it on looked like a setting that refused to save. The switch now reflects the real state.

"Usage pace" now actually turns the coloured trend arrows on and off — the switch was saved but nothing ever read it.

Focus mode, chat width, custom font and size, background image and blurred responses were all keyed to page structure Claude no longer uses. Every one of them works again, and the old hooks are kept so the desktop app keeps working too.

Claude Code: the Accounts button is back in the sidebar, and a tab opened on /code no longer stays stuck in limited mode after you navigate to a conversation — export, conversation metrics and live usage tracking were all missing for the rest of that tab's life.

Feature toggles (usage indicator, export buttons, favicon ring, conversation metrics…) now follow you across devices through cloud sync. They were local-only, so they had to be re-set on every browser and were lost on reinstall.

Two background loops that retried every half-second forever on pages where their target no longer exists are now bounded — they were running for the whole life of every /code tab.

Startup sync no longer fires its download and upload at the same time, where either could overwrite the other's work depending on which finished first.

The "Copy button" switch in Settings and the setup wizard. The feature it controlled was taken out of the extension back in v1.2.11; the switch stayed behind and did nothing ever since.

Firefox: the popup and the setup screens no longer open blank. The Firefox package shipped the app's raw source files instead of the built app, so nothing on those screens could start — every window came up empty. Firefox now gets exactly the same build as Chrome.

Firefox: usage tracking, notifications and cloud sync work again. The background service stopped a few lines into startup, which froze usage counts and left settings unsynced between devices.

UsageMeter has a new logo — the green usage ring on a dark tile. The extension icon in your toolbar, the popup header and the setup screens all wear it now, matching the website and the desktop companion app.

The extension is now called “UsageMeter — AI Usage Tracker for Claude”, focused on what it tracks out of the box. Nothing changes in the product itself.

Per-model limits in the popup. Claude tracks a separate weekly limit for Opus, Sonnet and Fable, and those percentages are now shown one per model, straight from Claude. A single blended ceiling was misleading: a million Opus tokens and a million Haiku tokens do not consume the same share of a limit, so one number could never be right for both.

Each model row now shows its own weekly percentage instead of a share of the window, and the overall ceiling is labelled as what it is — valid for the mix of models you are currently using.
