What is the Best ChatGPT AI app?
1. Nova
Our Verdict — Best Of The Best
Price: Starts at $29.99/month
Nova is an AI assistant that puts GPT, Claude, Gemini and Grok in one app. We think it’s the best of the best because you can switch models in the middle of a conversation without losing context, and it runs on the web, iPhone, iPad, Mac and Android.
The Best Part:
Every top model in one place. Nova gives you models from OpenAI, Anthropic, Google and xAI under one account, so you stop paying for four separate chatbot subscriptions.
The Worst Part:
The free plan is tight. Free users get limited messages on a basic model, and the premium models only open up on Pro at $29.99/month.
Get it if you want a ChatGPT AI app that lets you pick the best model for every task.
I recommend you start on the free plan, then take the 1-week Pro trial for $1.99 before you commit to $29.99/month.
(free plan)
Best For
Nova is best for individuals who want ChatGPT, Claude and Gemini in one app instead of paying for each one separately.
Top Features
Switch models, keep the context. Swap between GPT, Claude, Gemini and Grok mid-conversation, and the new model picks up right where the last one left off.
Bring your old chats. Import your conversations from ChatGPT, Claude and Gemini, so you never lose the context of your past work.
Create beyond text. Generate images, music and video with the latest AI models without leaving the chat.
A built-in fact check. Nova has a fact check feature built to cut down on hallucinations before you use an answer.
Hands-free. Voice mode lets you talk to Nova instead of typing, which makes the mobile app even easier to use on the go.

2. SudoWrite
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 for dirty talk, its Chrome extension lets you use it in Google Docs, and its Muse model is built just for fiction.
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 trial, then upgrade to the Professional plan for $29/month.
(free trial)
Best For
SudoWrite is best for anyone who wants to bypass the strict NSFW restrictions of ChatGPT.

3. PDF AI
Our Verdict — Best For Studying Documents
Price: Starts at $17/month
PDF AI is a site where you can upload PDF documents and ask ChatGPT any questions about them. We think it’s the best for studying documents because of how easy it is to use, the free plan to start with, and the clear answers with cited sources 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 ChatGPT-style AI app.
I recommend you get the free plan, then upgrade to the Pro plan for $17/month.

Top Features
Small print. You can ask PDF AI to explain complex matters, such as legal documents, manuals, dissertations, reports and more, in plain English.
No made-up BS answers. PDF AI highlights the text in the document it used for its answers, which makes it easy to locate the original source.

4. Frase
Our Verdict — Best For SEO Content
Price: Starts at $49/month
Frase is an AI content platform that helps you research, write, and optimize articles for Google and AI search. We think it’s the best for SEO content because it scores your drafts for SEO and GEO, then tracks whether AI answers in ChatGPT and Google AI cite you.
The Best Part:
Rank and get cited. Frase optimizes each article for Google rankings and for the AI answers that now sit on top of them.
The Worst Part:
Article caps. Starter covers 10 articles a month, so you need Professional at $129/month to publish 40.
Get it if you want ChatGPT-style writing help that is built to rank your content on Google.
I recommend you start with the 7-day free trial, then pick the Starter plan for $39/month billed yearly.

5. Rytr
Our Verdict — Best For Short-Form Copy
Price: Starts at $9/month
Rytr is an AI assistant that writes emails, posts, and ads in your own voice and helps you keep up with the people you work with. We think it’s the best for short-form copy because it turns a rough idea into a polished email, post, or ad.
The Best Part:
Sounds like you. Rytr writes in your own voice or one of 22 tones, so your short copy doesn’t read like a robot wrote it.
The Worst Part:
Free runs out fast. The free plan stops at 10,000 characters a month, so regular writers need Lite at $9/month.

6. Quillbot
Our Verdict — Best For Content Writers
Price: Starts at $19.95/month

7. ChatFAI
Our Verdict — Best For Character Chat
Price: Starts at $9/month
ChatFAI is an AI chat app where you talk with AI characters or create your own. We think it’s the best for character chat because you can build custom characters and chat with them as one of your own personas.
The Best Part:
Make your own characters. Every paid plan lets you create custom characters and keep your chats in unlimited storage.
The Worst Part:
