3 months ago, we wanted to try and see whether Claude, ChatGPT and Mistral are capable enough of helping us ship a small mobile oriented PDF scanning/editing application.
We went with Flutter as the tech stack, with native platform channels for message exchanging between the UI side and the heavy processing side which was implemented natively.
It took us 1.5 months to come up with a fully working iOS application which contains ALOT of features: - Merge, split, reorder, rotate, or delete pages - Fill & sign forms - Add annotations, highlights, comments, watermarks - Document Scanning with automatic edge detection & perspective correction - OCR & Text Recognition with over 98% accurracy + edit OCR detected text - Add / remove passwords - 100% offline (no cloud, no accounts, no tracking)
We got a 100$ monthly subscription for Opus and found out it's the best one to use for this kind of development. We generated some of the icons with Gemini and ChatGPT, tailored the app descriptions also with them.
We have made this free to use for now, at some point after we get more user traction we'll probably add a one time charge, no paywalls, no subscriptions. We're now looking into creating a partnership with DigiSign (a local digital provider for electronic signatures) to be able to add digital signing through the application.
So, long story short, if you have any ideas, don't let them go to waste, put in the work and great things will be waiting
