If you’re an iPhone user, here’s some good news: the well-known ChatPDF AI is now running a limited-time free promotion for its Premium Lifetime edition. As long as you get it during the period, you can use it forever for free with no restrictions.
ChatPDF AI is an app that uses AI to help you quickly read document formats like PDF and Word. Through AI chat, you can get the answers you want and summarize lengthy content. Even better, it also supports web pages, YouTube, and so on, and you can give it multiple source URLs at once to ask about anything you want to know. It’s super useful, and I highly recommend giving it a try.
But the developer didn’t say when the free promotion ends. These lifetime-free offers usually only last a day or two, so if you see this, grab it while you can.
ChatPDF AI also has an Android version, and it seems to have a limited-time free offer, but the free content shows a gray screen and can’t be seen, so I’m not sure if it’s the same lifetime free promotion. Android users can give it a try.
ChatPDF AI Lifetime Free! An AI that reads PDFs – get answers to any content through chat.
Although the ChatPDF AI interface is only available in English, it’s easy to use, and the AI chat supports Traditional Chinese. Since it’s unclear when the free promotion will end, remember to check whether it’s still $0 when you get it, and double-check again at checkout.
Compared to the free version, upgrading to the lifetime paid version gives you the following four major advantages:
- No page limit
- No daily upload limit.
- No term limit restrictions
- Long-form answers available.
Now when you open the ChatPDF AI App, a limited-time free offer pops up. The Lifetime plan is originally $1,625 USD, but right now you can get it for free. I tested it and successfully got it, confirming it’s free:
After going into my profile, I was indeed upgraded to ChatPFF Premium, and there’s no time limit:
The usage is very simple: after entering the main page, press Seleft File, and four options will pop up, supporting file upload from the internet, local upload, YouTube, and web pages.
The webpage partially supports providing multiple sources at once, meaning for the same topic, you can give it more source webpages. That way, when you ask questions, you’ll get more comprehensive and detailed answers:
You can converse in Chinese, and the answers it gives are quite complete and accurate, so it’s really useful. Although there are some common questions below, nothing happens when I click them. I’m not sure if it’s because of the Chinese content.
Content you’ve previously dropped will be independently stored by this app, so you can ask about it again in the future without having to provide it anew:
PDF I tested it myself and it works fine, and it also gives the correct answer:
I also tested YouTube videos and got very good results. Even without having time to watch the full video, I can quickly learn the key points through AI chat. Unfortunately, it seems to only read the subtitle text without timestamps, so there’s no way to ask about which time point specific content starts from.
This is really a great AI app. In the future, for any documents, webpages, or YouTube videos, if you want to quickly get the answers you’re looking for, this is all you need.
