View policyFrequently Asked Questions
Is Open Chat free to use, or does it require a subscription? high
The app is free to download but offers in-app purchases ranging from $4.99 to $59.99 per item. Recent user reviews indicate the free version has a very limited number of messages (some report only five) before requiring a purchase of the 'pro' version. The app listing confirms it has in-app purchases.

Does Open Chat show ads? medium
According to recent user reviews, the app displays ads, and some users report them as intrusive and excessive, appearing at startup and after each action. The official app listing states the app 'contains_ads' is false, but this may be a discrepancy or refer to a lack of third-party ads in a different sense.

Is Open Chat the same as ChatGPT? high
No. The app description explicitly states 'Open Chat is not affiliated with OpenAI.' It is a third-party app that claims to be 'powered by latest ChatGPT technology (GPT-4)'. Users should be aware it is not an official product from OpenAI.

How does the app's AI quality compare to other chatbots? low
Based on a limited sample of recent user reviews, some users feel the AI's responses are poor, with one reviewer claiming the AI itself suggested it wasn't worth paying for and was only good for basic facts. These are single-review observations and may not represent the general sentiment (the app has a 4.6 star rating from over 164k reviews).

1★It is Terrible not a good start. u open the app js to have ads popping up not one but two after another one after the ad is finished I click the type the same two ads show up again. look when I test out AIs I do it with an open mind but if keep on loading ads when will I use app. u want us to trust you by giving our money before we actually use ur app whr is the trust gained. please fix this immediately or u will lose customers which could be more prior to you than most of ur customers

3★I would give this 5 stars if it didn't limit each of my message to 400 characters. I bought pro to help with my writing but I can never send what I want rewritten in full because of the character limit. No other AI app I use has this issue.

1★This is a very bad app. There are too many ads and limited messages. You can only send five messages, after which you will be required to get pro version. It was a bad experience and its capabilities are limited other bots (e.g grok, deep seek and chat gpt) are quite better than this one.

1★the AI itself told me that it is not worth paying for. it stated that it is not good for fact. it is good for opinion and information that can be found widely on the web. for simple things like what happens when you add water and cocoa together or what color is the sky or is water wet. nothing else. not fact, not education. have canceled all AI subscriptions and I am now a sworn mortal enemy of all AI and its development

1★This app is a scam. First, it pretends to be an AI chat assistant but just shows ads. Now there’s a fake 'Web Search' button that does nothing—just a keyboard and no way to stop it from generating nonsense. There’s no stop button to interrupt the fake 'speaking' either. It’s all just empty UI tricks. Zero functionality. Do not install
