The AI tool I use.

📢 This article was updated on May 6th with some new content.

Since November 17th, when Notion announced the start of the Notion AI beta, I have slowly been trained to accept that if I want to use new products and tools, I have to join the waitlist. I'm not sure if it's humans training AI or AI training humans.

On November 30th last year, ChatGPT emerged like a tsunami, quickly sweeping across the globe. On Twitter, people were discussing in various languages what kind of changes ChatGPT would bring to the world and to humanity.

Shortly after the Lunar New Year, ChatGPT finally gained popularity in China, and various AI tools that utilize the OpenAI API emerged like mushrooms after rain. Software developers rushed to release new tools, and users eagerly followed, not wanting to fall behind the times. I'm ashamed to admit that I am just an ordinary person who is no exception.

To give an incomplete list, the AI models and tools I have experienced so far include Craft AI, Notion AI, Lex, ChatGPT, Invoke Ghostreader, Writeathon AI, New Bing, Midjourney, Poe, Claude, OpenCat, MacGPT, ChatGPT for Google, ChatHub, Stable Diffusion, Bard, and Image Creator from Microsoft Bing, among others. Currently, I am still frequently using Notion AI, ChatGPT, Readwise Ghost, New Bing, Poe, OpenCat, ChatGPT for Google, and ChatHub.

## Notion AI

Notion AI is based on the GPT-3 model provided by OpenAI. After specific training by Notion, it can provide users with automated data analysis, text processing, and natural language processing functions. Core features include writing, rewriting, summarizing, correcting, questioning, and translating.

I mainly use Notion AI to help me correct typos and punctuation, polish articles, write English emails and tweets, and translate and summarize foreign language articles subscribed in Inoreader.

## Invoke Ghostreader

This is a feature built into Readwise Reader. The model is reportedly based on GPT-3 and can ask questions, summarize articles, generate thought-provoking questions, create flashcards based on highlighted content, and even allow customization.

Now, when I'm reading articles that I'm not particularly interested in using Readwise Reader, I use this feature to generate summaries of the articles and decide whether to read them based on the summaries. For important articles, I let it generate questions as the theme of my reading notes.

## New Bing

I remember when Satya Nadella became the CEO of Microsoft, a friend confidently asserted that Microsoft would regain its vitality. From 2014 to this year, 9 years have passed, and it seems that my friend's prediction has come true. Whether it's Edge Browser, New Bing, or Microsoft 365 Copilot, Microsoft is showing signs of vitality.

Compared to the previous version of Bing, New Bing is much more user-friendly. The integration of GPT-4 and Bing's search engine has caused a stir, with some even claiming that Google is no longer as good. However, dreams always come to an end, and from a data perspective, New Bing's market share remains the same, and Google's dominant position in the search engine race is still unshakable.

I think the advantage of New Bing is that it is more reliable than ChatGPT when it comes to providing accurate information and citing sources and paper titles. Now, when I need to use a search engine, I consciously use New Bing first, and only turn to Google when I'm not satisfied with the results.

Currently, Microsoft is marketing New Bing together with Edge Browser. Even if users in China download Edge, there is a high probability that they cannot use New Bing due to network IP, DNS, and other reasons. If you encounter this situation or do not want to use Edge, you can download the [New Bing Anywhere]( plugin, which allows you to use New Bing and Image Creator from Microsoft Bing on any browser (except IE and Safari).

## OpenCat

[OpenCat]( is a product developed by independent developer [Baye aka 威力狈]( It is a native client for OpenAI and ChatGPT, providing a smoother and faster experience than the web version of ChatGPT.

Currently, OpenCat offers three versions, both the free version and the Pro version require an OpenAI API Key, while the Cloud subscription version does not. Specific features can be seen in the image below.

In OpenCat, I have created several chatbots using gpt-3.5 and gpt-4 to assist me with inspiration, information consumption, and knowledge management, among other things.

## [ChatGPT for Google]( and [ChatHub](

These two browser extensions are developed by the same developer, [wong2]( The former provides ChatGPT support for ten search engines, including Google, Baidu, Bing, DuckDuckGo, Brave, Yahoo, Naver, Yandex, Kagi, and Searx. The latter allows the use of ChatGPT, New Bing, Claude, Bard, and other models in one place.

Simply add the OpenAI API Key in the extension and configure it, and you can start using it.

My suggestion (excluding the wealthy) is to set the `Trigger Mode` of ChatGPT for Google to "Manually" or "Question Mark" (only activate when a question mark is entered at the end of a sentence) to save API usage.

To use New Bing in ChatHub, you need to log in to []( with an account that has access to New Bing. To use Claude, you need to log in to []( To use Bard, you need to log in to []( with an account that has access to Bard.

🆕 Update on May 6th: ChatHub now supports three-in-one and four-grid modes.

If you prefer to write prompts in Chinese, you can use the three-in-one mode, which supports Chinese for ChatGPT, New Bing, and Claude.

If you prefer to write prompts in English, you can choose the four-grid mode.

## ChatGPT Plus

I subscribed to ChatGPT Plus as soon as it was launched, and it's really useful. It's much faster than the non-Plus version, and you don't have to worry about the cost of using the GPT-4 API. Although you can only have 25 conversations with GPT-4 every 3 hours, it's barely enough. Recently, the Alpha version of GPT-4 with browsing was also released, allowing internet access.

However, this browsing feature, like the previously released GPT-3.5 with browsing, is not very useful.

I don't plan to renew ChatGPT Plus this month and will switch to Poe.

## Poe

[Poe]( is an AI product developed by the American version of Quora. It provides real-time online communication with AI robots. Currently, it comes with 7 AI robots, including "Sage" and "ChatGPT" based on OpenAI gpt-3.5-turbo, "GPT-4" based on OpenAI gpt-4, "Dragonfly" based on OpenAI text-davinci-003, "Claude+" and "Claude-instant" based on Anthropic's self-developed models, and "NeevaAI" based on Neeva's self-developed model.

In addition to these built-in robots, you can also create your own AI robots based on ChatGPT or Claude-instant, similar to OpenCat, without the need for an API.

Today, Poe announced that the web version is also available for subscription. Just as ChatGPT Plus is about to expire, I "defected" to Poe for three reasons:

- For the same price of $20 USD per month, Poe not only allows the use of ChatGPT and GPT-4 but also provides access to Claude+ and Claude-instant, making it more cost-effective than ChatGPT Plus.
- Unlike the limitations of using GPT-4 with ChatGPT Plus, Poe allows 600 requests per month for GPT-4 and 1,000 requests per month for Claude+. If the limit is exceeded, the speed will be reduced, but it can still be used.
- Other robots can be used without any restrictions.

These are the AI tools I use, and I hope they are helpful to you.
