Insert Text at a Position

Insert Text at a Position adds a string exactly where you specify inside existing text.

Provide the original text, the content to add, and a zero-based character position; the result preserves every original character and places the new content between the characters on either side of that index. It is useful for assembling templates, adding labels or separators, correcting generated content, and making precise edits in repeatable workflows. Unicode characters are counted consistently, so emoji and other characters outside the basic Latin alphabet do not unexpectedly consume two positions.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

Check your inputs

Use the labels and units shown next to each field. If something is missing or outside the allowed range, the page points to the field to fix.

Use it again or automate it

Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.

Get an answer now

Enter one set of values and see the result without building a spreadsheet or script.

Compare scenarios

Change one value at a time and rerun the calculation to understand what affects the result.

Automate repeated work

Use the API when the same calculation needs to run inside your product or workflow.

How do I use this capability?

Complete the fields above and run it on this page. The form highlights anything that needs attention.

Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.

POSThttps://api.kit.forhosting.com/str/insert-at-position

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

curl -X POST https://api.kit.forhosting.com/str/insert-at-position \
  -H "Authorization: Bearer $KIT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"Hello world","insert_text":"beautiful ","position":6}'
{
  "text": "Hello world",
  "insert_text": "beautiful ",
  "position": 6
}
{
  "task_id": "tsk_a1b2c3d4e5f6a1b2c3d4e5f6",
  "type": "str.insert_at_position",
  "status": "queued",
  "_links": {
    "result": "/tasks/tsk_…/result"
  }
}

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.
