Built a free PDF toolkit solo (with AI help) — need feedback on the in-browser text editor before I keep pushing on it Been heads-down on this for a while: thepdftool.in Standard PDF stuff : merge, split, compress, convert, OCR — but most of the conversion tools run entirely client-side (WASM), so files never leave your browser for those. Built solo, leaned on AI tools for a good chunk of the code and debugging. The feature I care most about right now is an inline text editor :— click i

Would Love Feedback on an AI Study Tool I'm Building I’m a high school student currently building Vulty, an AI study tool that organizes and turns lecture notes and PDFs into interactive, editable note summaries, flashcards, quizzes, and even 1 to 15 minute audio podcasts. We’re starting early access testing before launch, and we would love feedback and beta testers. You can test Vulty out at https://vulty.org/ . If you'd like to access Pro or Premium mode for testing for free, DM me and I c

How should I revive my Saas after 300 hours spent developing To provide context, a couple months ago I created a pdf to JSON ai extraction engine. I know... There are hundreds of products like this but for me the value proposition is that other solutions were heavy weight, expensive, non intuitive templates, and was slow. Therefore I created my own and I met my goals. I see genuine value in my product but the lack of users says otherwise. I think my best option is to build on top of this

I built a PDF redactor that auto-detects names, SSNs, and account numbers without sending your file anywhere - works on your phone too. Free, no sign-up. Plenty of redaction tools upload your file to their server first (no thanks for legal/medical/tax docs). Some keep the file local but send the text off to an AI, so the text still leaves. And most of the truly local ones only let you draw black boxes by hand, which is how those "redacted" documents in the news keep getting un-r

Upload your study materials to organize and share with classmates.
u/Ser_Duncen4126 · Reddit
Made a side project to organise the study material in college by creating study groups I've been working on a side project called StudyHubAI. The idea came from how difficult it can be to manage notes, assignments, and study material spread across different places. The app lets students upload PDFs and notes, ask questions based on their own study material, and get AI-generated summaries and answers. It also has study groups where students can share resources and discuss topics together.
