  I made a website that converts YT videos into step-by-step guides2024 · stepify.tech · ▲271

  Hey HN, I've been working on this side project for the past month. It generates a step-by-step tutorial guide for YouTube videos that you can follow along without watching long videos. Best suited for tutorial videos but can work for other videos aswell. No BS. Just straight to the point. The guides are generated from pure transcript so you don't have to worry about it being AI. It's my first project as a total beginner. Something I had to do inorder to get out of tutorial hell. Please let me know if you have any suggestions or if you face any problems or bugs. I would try to fix them to the…

  I made a tool to save multimedia from various platforms2025 · saveplays.com · ▲69

  My goal is to create a free media downloader that doesn't bother you. friendly, efficient, and has no paywalls or anything like that. I've been working on that for the last 3 weeks or so, it's not perfect yet, but it works, and I'm really excited to share it.

  Thumbnail X2025 · thumbnailx.com · ▲47

  Hey HN! Software engineer here. As an amateur youtuber, I've been struggling with thumbnails, especially since I don't have any design or editing skills. Decided to give it a try and make my own automatic thumbnail generator. Me being an ADHD person, made sure that there's no parameter tuning and shape choosing and fuss like that, just simply give prompt and generate thumbnail. Increased my CTR from 1.2% to 2.3% (faceless fantasy books niche on youtube) Thumbnail X (completely free for now) - https://thumbnailx.com/ Just wanna add that this is by no means a perfect thumbnail…

  Seedance Video Generator2025 · seedance.tv · ▲32

  Hi HN — I’m an indie maker building Seedance AI. It helps people create short videos (and images) from text prompts and reference photos. I tried to keep it simple: fast templates, predictable credit pricing, and downloadable results. It’s still early, and I know there are rough edges. I’d really appreciate honest feedback on what feels useful, what feels confusing, and what I should improve first. Happy to answer technical or product questions.

  Came across this tool today and figured some folks here might want to kick the tires. Link: https://seedance-2.net/ What it appears to offer • Text to video generation via a simple web UI • The site claims up to 4K output and watermark free downloads on paid plans • Pricing mentions batch generation, private generations, and API access on higher tiers Why it might be interesting • Low friction to test since it says you can start without signing up • Could be useful for quick marketing clips, product showcases, or social content Questions for anyone who tries it • How’s prompt…

  GIF.new2025 · gif.new · ▲18

  i use GIFs a lot in my personal/professional life and so I'm pretty passionate about the topic :P about a month ago I found out that this domain was available and couldn't believe it. Waited a good 3 weeks to pull the trigger on buying it (which, btw is hella expensive by default) and in the meantime, hopped from one idea to another on what it should house. original idea was to build some kind of prompt-to-GIF service but very soon realised that i can't sustain the AI bill on my budget (top contender was to use runway). then came the idea of animating charts from data (obvious: i work…

  LLMs can generate valid JSON 100% of the time▲854

  Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
