Please make this compatible with iphones, the largest models would work great with this app. Also, why does it require openAI organization ID when every other app requires just the API key? Also, I mean that ai cannot paste directly into the app as I cant seem to find a way to past an entire diagrams syntax at once. If it has to be done line by line even when importing existing text, I cant use this currently.(Your app is the only app doing this so it deserves 5 stars.)

Hi Bran321If copy & paste doesn't work as expected you can either share your diagram using iCloud or other connected server (e.g Drive) because the app supports standard IOS document management.Let me Know whether this solve your issue

Very good idea, but terrible implementation

This app is not even alpha level. Very good idea, but provides only line editing. Cannot select text across lines, cannot delete “new line” character.Even more: once created text and app saying it saved it, switch to diagram or get out to list of docs and back and half of the text disappears.Don’t know what AI would do here, but base on current state of the app, I guess nothing.Completely useless piece of junk as for now. Don’t worth even $.99.Hope they will make it usable and free to try.

Developer Response
Thanks for feedbackObviously the design choice to use an line editor instead of a free text editor seems not a good choice 🙁.The 0.99$ is a symbolic price that help me to be committed on continuous improvement. I've planned a release 2.0 with a free text editor, hope this new release will change your mind about this app 🙏Do you have interest to be a beta tester for new release ?

HANDY AND HELPFUL APP

This app is extremely helpful for software engineers and architects. With the support of AI-generated scripts, it allows users to quickly create visual diagrams, which makes UML modeling and architectural discussions much more efficient.I hope the developer continues to improve it and make it even better.

- avoid reset picker selected tool on hidden - start drawing view with scroll locked by default - general improvements
