Good to know

How these tools work

See the working

Loan and mortgage results come with amortization schedules, so you can check a quote line by line.

Your figures stay private

Nothing you enter is sent anywhere. The budget planner and expense splitter save in this browser's local storage, and both export to CSV.

Estimates, not advice

Results depend on what you enter and on simple assumptions such as a fixed rate. Use them to compare options, then confirm with your lender or adviser.

Questions

Frequently asked questions

Are the loan and mortgage results accurate?+

They use the standard amortization formula, so for a fixed rate they should closely match a lender's quote. Real offers can differ because of fees, insurance and rate changes.

Which tax rates does the salary calculator use?+

You enter your own tax brackets, so it works for any country. It does not ship official tax tables, which change every year.

Is this financial advice?+

No. These are general calculators for planning and comparing. For decisions about borrowing, tax or investing, speak to a qualified adviser.

PDF

Everything runs in your browser, so a signed contract never leaves your computer. Most of these take files up to 75 MB and 500 pages.

Business

Invoices, receipts and quotes print to an A4 PDF straight from the page. The CV maker and Kanban board save as you go, in this browser rather than an account.

Documents

Draw a signature with a mouse, trackpad or finger, or type one, then download it as a transparent PNG, an SVG or a JPG.

Writing and text

Counters for words, characters, syllables and reading time, a text diff, a notepad that saves locally, and a typing test that compares you with the last hour of results.

Images

Nine of these send the image to our server, where it is converted in memory and not kept. The other eight, including HEIC to JPG and the cropper, never upload anything.

Calculators

The biggest section: dates, ages, grades, units, sleep cycles, dice and timers, plus a scientific calculator that handles complex numbers and solves equations.

Developer

JSON, regex, hashes, UUIDs, JWTs and subnets, plus tests for your keyboard, click speed, dead pixels and refresh rate.

Music

A metronome with swing and accents, a pitch pipe, tap tempo, the circle of fifths, and a transposer that reads ChordPro chord sheets.

Audio and video

Check a microphone, speakers or webcam before a call, watch sound on a spectrum analyzer, or record from your webcam. Recordings stay in the tab until you save them.

Crypto

Profit and loss, DCA, staking, gas fees and liquidation prices. Nothing connects to a wallet or a price feed; you type the numbers in.
