Add a ๐Ÿ“… "Date Stamp" to all Chats with "datestamp"

This is a very simple and useful ChatGPT Builder App I built using AImarkdown Language

See sample shared chat:

Complete datestamp source code:

Iโ€™m still testing this out and improving it. If you find anything not working, please reply to this topic.

I was never able to reliable get ChatGPT to handle the current date. I tried everything - even writing Python Code to get current date - which did work some of the time. So, I wrote datestamp which uses a public API call:

Using @mentions I can add it to any of my Chat conversations.

A ChatGPT Builder App using AImarkdown Language


datestamp allows users to easily track conversations by adding the prefix ๐Ÿ“… YYYY-MM-DD to each response.


  1. You can search ChatGPT for any date
  2. Change time zone with natural language
  3. Change behavior of datestamp with natural language
  4. Type /toc to see a โ€œTable Of Contentsโ€ of all responses, with date and truncated response.
  5. Type /help to get help

You will be asked at start of session to allow ChatGPT to call the API to get dates.

Use Cases

  • Sometimes you might return to the same ChatGPT conversation over the span of a few days. If you used datestamp - it is easy to sort out the dates of each response.
  • For long conversations, the โ€œTable of Contentsโ€ feature is a perfect way to review not only the date of the responses, but also a truncated summary of each response.

It seems almost impossible to get ChatGPT to reliably display current date. This is why an โ€œAPIโ€ call is needed.

Configuration For ChatGPT Builder




Prefix all responses with current date: ๐Ÿ“… YYYY-MM-DD. Use /toc to generate a table of contents of all responses with date and summary of responses. AImarkdown source code available at: . Type /help for help.

would be enough just a timestamp text (ie. 2024-02-09 12:47 UTC, or so) INCLUDING in the question, not only the gpt answer!
The icon is not bad, just cosmetic
