Autonomous AI research engine that generates full academic papers with real citations from a prompt.
@fedeponte1 · X
my first saas. i think i built something people actually want and completely failed at the business side. would genuinely love help. openpaper ( writes full, cited research papers from a prompt. research, outline, writing, real citations, export. the honest numbers: - ~2,300 signups - ~1,500 generated a full paper. people actually use it. - ~5 have ever paid. ~$45/mo. activation is great, revenue is basically zero. i've been staring at this for weeks. the paywall is on export (pay ~$12 to download the pdf). but the full cited paper is right there on screen, free, you can read it and copy-paste it. so i'm charging for the gift wrap after handing over the gift. almost nobody even reaches checkout. 76% generate exactly one paper and leave. one-and-done, so subscriptions make no sense. the audience is mostly students and researchers on personal gmail, all over the world, almost none on university or company emails. traffic is x and github. so i genuinely can't tell

Convert GoodNotes archives to SVG, PDF, and JSON formats using 100% local processing.
Kaih1825 · HN
Hi HN, I'm the author of this project. I built this because I wanted my handwritten notes to truly belong to me—free to be migrated to other apps instead of being locked inside the proprietary Goodnotes ecosystem. To be honest, I have absolutely no background in reverse engineering or binary file parsing. I built this almost entirely through "vibe coding" (using LLMs as my pair programmers—mainly Gemini Pro/Flash, and occasionally Claude Sonnet). My ultimate goal is to unlock .goodnotes files so

Apply movie-inspired color grades to photos in a browser-based editor with one click.
u/huuughmangasorr · Reddit
I built a tool that gives your photos a movie color grade (no AI generation) I kept seeing photo tools that "cinematic-ify" images by running them through AI and spitting out something that's basically a different picture. I wanted the opposite: keep my actual photo, just make it feel like a frame from a film. So I built CinematicPhoto — a browser tool where you upload a photo, pick a movie look, and get a graded version back. Your original stays intact; it's color grading and effects d
