Here are the best custom GPTs for chatGPT based on data OpenAI as well as from Similar Web over the last 28 days.

Right now, It’s the best overview on most used chat gpts we can get, until OpenAI finally release the delayed GPT Store.

Note that SimilarWeb data is usually provided with 48–72 hr lag.

Last updated: Wednesday 3 Jan 2024
Timeframe: Visits cover previous 28 days, Chats cover all time.

The full list is in this Github repo.

Most visited Chat GPTs

Before OpenAI shared the number of chats for each GPT, I determined the most popular GPTs based on visit data from SimilarWeb.

How? See the FAQ at the end of this post.

Here are the current top 5 based on traffic over the last 28 days upto 3 January 2024.

  1. Image Generator: A GPT specialized in generating and refining images with a mix of professional and friendly tone.

  2. New GPT 5: AGI-like AI, excelling in reasoning, personalization, and confidentiality.

  3. Consensus: Formerly ResearchGPT. Search 200M academic papers from Consensus, get science-based answers, and draft content with accurate citations.

  4. ChatGPT 公式日本語版: ChatGPT 公式日本語版

  5. AI PDF: Ai PDF GPT (Top PDF GPT), can handle PDF documents up to 2GB each, allows 1000s of PDF uploads on myaidrive.com with a free account. It eliminates the need for repeated file uploads. PRO version can search across 1000s of PDFs and OCR documents. Provides superior summaries for lengthy documents.

A couple of things to note on this:

  1. Not sure how some users manage to create GPTs with the term “ChatGPT” — in the past the UI did not allow this. But it seems Johnetta Kovacek is having great success releasing a number of language specific GPTs.
  2. Consensus have finally renamed their GPT. They were the first to release a GPT called “Research GPT” — but a few weeks later a competitor GPT launched called “ResearchGPT (Official)” and they managed to grab the researchgpt.com domain. Good decision to rebrand their GPT.
  3. Visit data does not resemble usage. So number of chats, especially the delta over a period, will be a much better metric.

Best GPTs based on Chat Data

OpenAI’s ChatGPT now shares one of the vanity metrics for each GPT. So of course we capture that data now.

Here is DuckDB query of our gpts.csv file showing the top 10 GPTs by the number of chats.

Most Popular GPT Creators

The great thing about DuckDB is that is also makes it super easy to create aggregations.

Here are the top GPT creators by total conversations/chats created on their GPTs.

  1. Consensus
  2. Mindgoblin Studios
  3. My AI Drive
  4. Dainis Tkacovs
  5. Ask Your PDF

Turns out some folk have started using the data from my Github repo to create web frontends to make browsing / searching the full list easy!!

Frequently Asked Questions

Here are some common questions.

Where do you get your visit data from?

The visit data is from SimilarWeb popular pages feature. This dataset lists all URLs for a domain that get notable traffic. Right now it only provides a desktop / mobile % share of traffic. So I mutliply the %share by the total visits to the domain chat.openai.com.

Where do you get your Chat data from?

OpenAI have started exposing vanity metrics for each custom GPT in the pages source — currently there are 3 metrics of which 1 has data:

  • num_conversations_str: Rounded chat count to nearest 1000
  • num_pins: Currently always 0
  • num_users_interacted_with: Currently always 0

You can see these by loading a GPT url in your browser and inspecting the __NEXT_DATA__ variable:

console.log(__NEXT_DATA__.props.pageProps.gizmo.gizmo.vanity_metrics)
