### 1/5 — Waste of time

*2026-01-21*

Update: Thanks for the response. The links to contact the developer don’t allow me to email you. How can I contact you? 


You have to add or import words. Try importing from a pdf file and you find that your ChatGPT limit is exceeded with just one page. 
Try importing from a photo and you get a weird bouncing pop up that prevents you from selecting and cropping. 
Unusable, unless you manually add words. But, then, life is too short.

**Developer response:** Thanks for your feedback. As the first version I tried to make it as personal use, I didn’t test it thoroughly. I tried to fix the bugs in app regarding pictures reading. For ChatGPT limit problems, it should not exceed. I use ChatGPT, it just 0.5 euro every month. Have you topped up some money in ChatGPT account. If not, you cannot use it.

I have uploaded a new version. If you are interested in using it again, I can send you a code to use the app for free. Welcome more feedback from you
