What’s New

Version 1.3.1

Mostly bug fixes, with a few tweaks:
- New icon on welcome screen
- Fixed bug on initial conversation not working after install
- Fixed a few other bugs to hopefully make it more stable
- Removed "Regenerate" button when there are no messages in a chat
- Removed decimal places for token count in conversation settings

This bug took way too long to track down, but now that I did, hopefully I can move on to adding more functionality.

Clean interface needs more OpenAI account cost transparency

For what ChatAI is—a clean iOS-native interface to ChatGPT—the app does its job well. However, it needs better transparency about how your personal OpenAI account ties into the experience in order to be truly useful. It seems there’s a hidden actual “total cost of ownership” which is probably nominal, but led to a puzzling disablement of ChatAI’s connection to ChatGPT in my case.

After a couple weeks of using this app, my prompts within ChatAI started retuning errors that I had exceeded my quota. Digging in on OpenAI, the $18 worth of gratis tokens provided initially by OpenAI for trying the API interface that ChatAI utilizes on my behalf (of which I’d used up only a few pennies’ worth) had expired at the beginning of the month. I presume I’ll need to supply OpenAI with a credit card to continue using ChatAI. While I presume that will continue to be less than $1 per month based on my token utilization, it would have been nice for ChatAI to clue me into the issue differently.

Better connectivity into your underlying OpenAI account would be helpful too. I think casual users are likely to be confused by OpenAI’s pricing, which is, of course, on top of the price for this app. The $20/month ChatGPT Plus option doesn’t currently cover API utilization at all. API use is a separate charge, metered by natural language token counts within the prompts you submit. (Something higher than the word count.)

Great app! I just have 2 issues with it

I love this app, I’m glad I found it through a Reddit post, I use it very often, and mainly have no issues except these two problems.

GPT-4 can not handle long or semi-long prompts. It will take forever to load and then it will just say “the request timed out” and trying to regenerate it will just produce the same results. Sometimes the prompts will work and sometimes it doesn’t. it’s just a bit annoying when I try to regenerate it again and again and it keeps failing.

Secondly, I was trying to delete old conversations with the AI, and it somehow deleted the ones I was still actively using and I couldn’t find them anymore, so i was a bit annoyed by that. Possibly adding a trash folder could be helpful so you can restore a prompt if it accidentally gets deleted.

Other than that this is a well made app. I will continue to use it.

The best, cleanest, privacy-focused app available for ChatGPT

Hey ! Just wanted to say how awesome your ChatAI app is. I've tried a few other apps on IOS, but they always seemed overpriced or had some kind of predatory pricing/data model. Your app is seriously a breath of fresh air! I love that it uses my own API and saves chats locally, and the native interface is so much faster than the web interface. It's also great that it's a lot cheaper than having to pay for ChatGPT Plus just for the reliability and speed (which, after recent events with OpenAI, is questionable anyway).

I can't believe that you made this app for yourself and decided to share it with others. You’re awesome :).

Thank you SO MUCH for creating such a fantastic app! I'll definitely be recommending it to my friends and family.

Just a couple ideas for the future:
1. Implementing a dark-mode
2. Being able to save custom, user-made personality prompts in the existing menu you created (to avoid having to copy and paste the settings over one once you run out of tokens in a conversation)
3. Perhaps sync conversations over iCloud? Not sure if that’s possible or not.
4. When running on an M1 Mac, hitting Enter on the keyboard does not send the conversation (you have to manually click send each time).

Edit: oh and I forgot to mention - even though there isn’t a native macOS app yet, it actually works really well on there, too :).
