Small tools for people on deadline.

Count the post, land the age, file the report. Each one opens and works, with nothing to sign up for.

Five tools, one job eachCount a post, work out an exact age, price a mortgage, move text between devices, turn posts into a report.

Nothing to sign up forNo account, no sign-in, no ads. Each tool opens and does its job.

The Tools

Five you can use right now.

Three more are on the bench. Each row opens the tool; nothing here asks who you are.

01Character Counter for X

The count you see is the count X sees.

X weighs a link at 23 characters whatever its length, an emoji at two, an accented letter at two. Your text editor weighs none of that. Paste the post here and the number is the one the post box will show, before you are standing in front of it.

  • Weighted the way X weighs it: links, mentions, emoji, CJK
  • A live preview of the post as it will land
  • One tap to copy. Nothing leaves the page.

Under the HoodA counter that implements the platform's weighting rules, pinned by a test suite so a rule change cannot ship silently.

02Any Date In, Exact Age Out

The age, correct to the day, in the time it takes to paste.

A date of birth arrives as 4/7/86, or 7 April 1986, or 86-04-07, and the statement is due. Paste whichever one you have. Years, months and days come back exact, including on leap days and at the end of a month, and copy clean.

  • Reads the formats people actually write
  • Exact on leap days and month ends
  • Copies clean, ready for the statement

Under the HoodA parser for the dates people really type, with the edge cases (leap days, month ends, two-digit years) held by tests.

03Price, Monthly, Compare

Start from the number you know.

Set the price and read the monthly, or set the monthly and read the price it buys. Taxes, insurance and PMI are already inside that number. Save the places you are looking at and put two of them side by side with every figure showing.

  • Bidirectional: whichever number you know, start there
  • Everything in the payment, including PMI and when it drops off
  • Compare two saved places, every number shown

Under the HoodA bidirectional solver with amortisation, PMI drop-off and FHA rules, checked by 32 formula tests.

04Text Between Your Devices

To your other phone, and to no one else.

Pair two devices with a code and send. The text is sealed before it leaves and opened only on the device it reaches; the server in between carries a box it cannot open. No account, and it works with no connection at all.

  • End-to-end encrypted, with the keys only on your devices
  • Pair by code or by QR, on any network
  • Installs as an app and works offline

Under the HoodEnd-to-end encryption in the browser, a WebSocket room, QR pairing and an offline PWA, with an end-to-end test that runs the whole exchange.

05Posts Into a Clean Report

Paste the sheet. File the report.

The spreadsheet of posts you already keep becomes a formatted report: usernames as working links, consistent type, categories in order. Edit it in place until it reads right, then copy it out.

  • Paste straight from the sheet you already keep
  • Usernames become links; the formatting holds
  • Edit the document in place, then copy it out

Under the HoodA paste-to-document pipeline with automatic categorisation and an in-place editor, pinned by tests for escaping and report shape.

Extra Care

Made to be lived in.

Two cities, night and day. One accent you choose, read by every tool. Weather that rains on the river. Try them here; each tool remembers what you picked and the rest follow.

Theme

Night and day are two different cities. The light, the water and the windows all change.

Accent

One colour, used only where you are meant to look. Pick it once; every tool reads it.

Weather

Rain rings the river, snow settles on the roofs, and the wind moves all of it at once.

Built in New York by DS.

Every tool here began as a job that kept getting in the way of the real work: a count, a date, a report due by noon. DS builds them, ships them when they are useful, and keeps them free, private and fast. This page is the portfolio. The city is drawn live in your browser, the weather is physics, and every tool is a working product you can open right now.
