Our Verdict — Best Of The Best

Price: Starts at $20/month

ChatSonic is an online tool that can be best described as ChatGPT on steroids. We think it’s the best of the best because of its comprehensive AI toolbox, access to Google Search, and its great mobile app. 

The Best Part:

  • AI octopus. Chatsonic is only one of the many AI tools of WriteSonic. Together they overshadow the experience of a standalone chat AI app, such as ChatGPT.

The Worst Part:

  • Fake facts. Despite all the whistles and bells, you cannot completely rely on the accuracy of the output, so make sure to double check facts on content Chatsonic generates.

Get it if you want the best ChatGPT AI app that can do a lot more than the original app.

I recommend you get the Free trial, then upgrade to the Business plan (with GPT 4 - 32K) starting from $19/month.

Our Verdict — Best For NSFW Content

Price: Starts at $19/month

SudoWrite is an AI writing assistant with no adult content filters. We think it’s the best for NSFW content because your account won’t be blocked because of dirty talk, its chrome extension which allows you to use it in Google docs, and the combination of several language models. 

The Best Part:

  • Filling the gap. SudoWrite shines where ChatGPT draws the line. If adult content creation is your thing, you can best add this AI app to your tech stack.

The Worst Part:

  • Different beast. Storytelling is the biggest strength of this AI app and that makes it less useful to people who just want to chat to an uncensored chatbot. 

Get it if you want to generate erotic and pornographic texts without worrying about violating the strict ChatGPT policies. 

I recommend you get started with the Free plan, then upgrade to the Professional annual plan for $120/year.

Our Verdict — Best For Studying Documents

Price: Starts at $15/month

PDF AI is a site where you can upload PDF documents and ask ChatGPT any questions about it. We think it’s the best for studying documents because of how easy it is to use, the unlimited usage, and the crystal-clear answers you get in no time.

The Best Part:

  • Unboring PDFs. You no longer have an excuse to store PDFs for later. Upload any PDF document and ask the AI app to summarize, paraphrase or explain the content in plain language. 

The Worst Part:

  • PDF only. At this moment, you can only upload PDFs, so you will waste some seconds with converting other file types, such as docx, xlsx, etc.

Get it if you want to quickly analyze PDF documents with the help of a trained ChatGTP-based app.

I recommend you get the free plan, then upgrade to the Premium plan for $15/month.

(free plan)
