// workflows/new

Build a workflow.

Pick the capabilities, say where each field gets its value, and run it before you save it. Building one costs nothing: what an account changes is where it is kept. Every rule the server enforces is checked here as you type, so saving cannot fail for a reason you could not see.

This is the "How long until the deadline, and which week is it?" example with its sample values filled in. It is not saved yet: change anything, test it, then save it as your own.
· What it is called
· What it asks for

Declare a value here when it changes from run to run. Steps read it by its key. Anything that never changes belongs in the step itself as a fixed value, not here. A workflow may declare up to 10 inputs, and none at all is fine.

· What it does

Steps run top to bottom, one after another. A step can use a fixed value, one of the inputs above, or the output of any step above it. Up to 12 steps.

Every one of its 2 steps is pure computation, so a test run in the builder happens on your own machine and costs nothing. Your input is not sent to us for it.

Run from your saved workflows, from your code or from an assistant, the work happens on our machines and is metered: 2 credits, one call per step across 2 steps.

Adding a step that needs our side, meaning anything touching a key we hold, a database, the network or a file, would move the whole run onto our servers and it would be charged there too.

Date Difference Calculator

The time between two calendar dates: total days, weeks plus days, a years/months/days breakdown, hours, and the number of business days (Monday to Friday, no holidays). Order does not matter; the end date is excluded unless includeEndDate is true.

Reads: startDate from input "from" · endDate from input "deadline"

Gives back:start textend textstartWeekday textendWeekday textswapped yes/noincludeEndDate yes/noyears numbermonths numberdays numbertotalDays numbertotalWeeks numberweeksAndDays objecttotalHours numberbusinessDays number, usable by every step below as “Output of an earlier step”
· Where each field comes from
startDate (required)Text (String)

The first date as YYYY-MM-DD. Example: 2026-01-01

endDate (required)Text (String)

The second date as YYYY-MM-DD. Example: 2026-12-31

includeEndDate (optional)Yes/no (Boolean)

Whether the end date counts as a full day. Defaults to false. Example: false

Left out. The capability will use its own default.

What this step gives back
{
  "start": "2026-01-01",
  "end": "2026-12-31",
  "startWeekday": "Thursday",
  "endWeekday": "Thursday",
  "swapped": false,
  "includeEndDate": false,
  "years": 0,
  "months": 11,
  "days": 30,
  "totalDays": 364,
  "totalWeeks": 52,
  "weeksAndDays": {
    "weeks": 52,
    "days": 0
  },
  "totalHours": 8736,
  "businessDays": 260
}

A later step reading this one can take the whole object, or a path into it such as start.

Week Number

The ISO 8601 week number and ISO year for a date, with the Monday and Sunday of that week, plus the US (Sunday-based) and UK/EU week numbers. Defaults to today when no date is given.

Reads: date from input "deadline"

Gives back:date textweekday textisoWeek numberisoYear numberweekStart textweekEnd textusWeek numberukWeek number
· Where each field comes from
date (optional)Text (String)

The date as YYYY-MM-DD. Leave out for today. Example: 2026-09-07

What this step gives back
{
  "date": "2026-09-07",
  "weekday": "Monday",
  "isoWeek": 37,
  "isoYear": 2026,
  "weekStart": "2026-09-07",
  "weekEnd": "2026-09-13",
  "usWeek": 37,
  "ukWeek": 37
}

A later step reading this one can take the whole object, or a path into it such as date.

· Test it before you save

This runs the workflow exactly as written, without saving it. It uses the real capabilities, so what you see is what a later run will do. Inputs are prefilled from the examples you gave them.

Stays on your device

This runs in your browser. What you put in is never sent to ToolForte, so we could not read it if we wanted to.

One exception, so the sentence above stays true: when a run finishes here we record that it happened, which ready made workflow it came from if it came from one, how many steps it had and how long it took. Never what you put in, never what came back, and never anything written into the steps themselves. It is how we can tell which tools are worth keeping.

Runs in your browser. No credits, nothing sent to us.
