The tools you keep a tab open for

Pick two dates and get the exact number of days, weeks and months between them, or start from one date and jump forward or back by a number of days. It runs entirely in your browser, so it keeps working with the Wi-Fi off.

The quick calculator for the moments you just need an answer. Fully keyboard-driven, no ads in the way, and it keeps working when your connection does not.

Turn 1,250 into "one thousand two hundred fifty" in one step. Handy whenever a number has to be written out in full: cheques, contracts, invoices and legal documents.

Twenty-five minutes of focus, then a short break, repeat. The difference here is that the timer lives on the same canvas as the work. Your notes and your task list are right beside it, not in another tab.

Set a target date and watch the days, hours, minutes and seconds tick down. Focus mode clears away the list and blows the target up into one big number, easy to read at a glance.

Start, log, pause, reset. Each log keeps the running total plus the lap time since your last log, precise to a tenth of a second, so you never have to do the subtraction yourself. Run more than one at a time, each with its own name.

Set an alarm for a specific time of day in the browser tab you already have open. No app to install, and nothing to sign into.

Set a duration, press start, and get an alert when it runs out. Save any duration as a quick set so it is one click next time, the classic kitchen timer, in the tab you already have open.

Paste your text, then click the case you want: UPPERCASE, lowercase, Title Case, Sentence case, camelCase or snake_case. It converts in place, ready to copy.

Drop in a screenshot or photo and get the text back out, in any of 18 languages including Chinese, Arabic, Japanese and Korean. The image is processed in your browser, which means it is never uploaded. That is a real difference if the screenshot has anything private in it.

Keep the cities you actually work with on screen at the same time. Useful the moment your team, your clients or your family are not in your time zone.

A full Excalidraw whiteboard, on the same canvas as everything else. Sketch a diagram, a flow or a rough wireframe in the hand-drawn style that makes it clear an idea is still a draft.

A proper writing surface, not a plain text box. A slash menu for headings, lists, tables, equations, embeds and even a live Workbook block, checkboxes that carry a scheduled date and an importance level, headings that fold away to hide what is under them. Every task you write here shows up on your boards automatically.

Write your thinking on the left, get answers on the right. Each line is calculated as you type, with live suggestions for units, conversions and functions you can accept with Tab. Name a line and reuse it as a variable further down, and it understands units and currencies in plain language.
