Author: bilater
Description: All -
Wanted to share this cool new feature to http://you-tldr.com: TLDR Academy!
We’re expanding our focus to help students who use you-tldr for lecture insights. With our new feature, you can simply paste a playlist URL and you-tldr will:
Scrape all videos in the lecture series Generate transcripts Create comprehensive summaries Extract key takeaways Provide practice questions based on the lecture content
It’s still in early stages, but I’m excited about this feature and looking forward to developing it further!

2. Show HN: A CLI GitHub issue creator
URL: https://github.com/solid-adventure/gh-issues
Author: james_marks
Description: I find value in creating high quality GH issues in the repos I maintain, but find myself not documenting features and bugs when I come across them. I work across 6-8 repos regularly, so even bringing up the right URL for the repo is a series of micro-efforts and clicks I do many times a day.
I tend to have the directories for each these repos open already in my shell, so I wanted a way to A) leverage that I’m already looking right at the repo because this is where I do my commits, pulls, etc and B) not switch contexts to a website.
I’m guessing many people have solutions in their editor with deeper git integration, but I’ve never gotten into the habit of using those tools.
When I plugged Claude in to help fill out the issue body, I was impressed by how spot-on the (admittedly very few) examples were, and it made me realize just how +common+ some of the problem I want to create issues for are across apps, and the boilerplate captures them well.
I suspect I’ll still want to put some finishing touches on new issues on GitHub.com, so the script prints the URL after an issue is created to at least save me the URL lookup so I can go drop images, etc.

5. Show HN: Discover Your Core Values
URL: https://corevalueswizard.com/
Author: ChilledTonic
Description: Hey HN,
A few years back I did a core values discovery exercise with my positivity coach and I found it to be a transformative experience. It’s been a process I’ve recommended to friends time and time again, but usually it requires a second person to walk through the process.
There are tools online that do a similar thing, but I find almost all of them to be kind of predatory and scuzzy - a lot of coaching woo without a lot of substance.
This “wizard” guides you through the simplest form of a values discovery exercise. It’s forever free - and I’m curious to know your thoughts.

6. Show HN: LogMyBP – A little blood pressure log utility I made for my parents
Author: SmellTheGlove
Description: I’ve always been a bit nervous to share my little projects, but I convinced myself to start throwing things out there.
LogMyBP is a tiny (arguably toy) app I built to help my parents keep track of their blood pressure readings. Following an episode, one of my parents needed to log readings three times daily, in three different positions. At first they did it on paper, then a gsheet. Seeing as how my folks aren’t the most computer-literate, I was doing a lot of tech support to help set up and maintain this gsheet template. Naturally, I decided to over-engineer a solution.
LogMyBP is intended to help my parents, who can use a web browser, email, and a smart phone just fine, but get frustrated when creating accounts, remembering passwords, or installing apps. This requires none of that - they just have to put in their email address and readings, and the app takes care of recording and retrieval. It does so by creating an “account” using their email address on the fly, and lets them verify and reuse it with an emailed magic link. Once logged in, they can export their readings to a formatted text file for printing, or a CSV file to open in sheets or excel and bring that to the doctor. I also tried to keep the UI descriptive, high contrast, and very simple.
Technical bits: I decided I’d build this quickly with the help of an LLM, just to see how far I’d get. ChatGPT did a great job, but I’m enjoying Claude Sonnet as of now. It’s a Python, Flask, Tailwind, and SQLite app, running on Fly.io. ChatGPT and Claude are really good at Python, as well as HTML templating. I suck at the latter, and they saved me a ton of time. I also attached a self-hosted version of Plausible since I wanted to learn how to do that vs use 3rd party telemetry.
Feel free to play around with it.

10. Show HN: Doctly AI – Accurate AI-Powered PDF to Markdown Parser
URL: #
Author: kapitalx
Description: I’m one of the co-founders of Doctly AI. I wanted to share our story.
We didn’t originally set out to build a PDF-to-Markdown parser. It all started when we were building a RAG solution for a company that deals with regulatory agencies. All of their data was in PDFs, and as it is apparently with lawyers, they like to print and scan documents to make it hard on their counterparts. These documents contained complex tables that barely make sense, are rotated, and handwriting is mixed in between. Many pages are number ruled and potentially rotated.
We spent a lot of time trying to get clean data from the PDFs. Most OCR tools spit out garbage among the output and also can lose formatting and document hierarchy. We also wanted to reference the original documents within the RAG output, creating additional challenges. The existing solutions we looked at were unable to give us the quality we were looking for. Garbage in/garbage out.
“Let’s just write our own. How hard could this be?” - we thought. Well it is definitely a difficult problem. AI vision models can do pretty well, but different ones excel at different things. From language support to table and chart conversion. Also cost becomes an issue.
We settled on an “agentic” approach where we detect features/layout within the document and route them to different models and in some cases traditional OCR, achieving very high quality conversions, while keeping the costs at bay. After comparing our solution with existing solutions and APIs, we easily beat them on the quality of their ‘high-res’ offerings while matching or beating their ‘low-res’ costs.
We still have work to do of course, we believe we can increase the quality and reduce the costs by a lot, but you have to start somewhere.
We’re offering free credits so you can try it out for yourself! Check us out at Doctly.ai, No credit card required. Let us know how it helps with your document processing! Let me know if you need more credits for testing it out.
Would love to hear your feedback, and leads are always appreciated :)

11. Show HN: Create Waitlist Pages
URL: https://www.fastwaitlist.com/
Author: ondrej_bartos_
Description: I decided to launch FastWaitlist because I was facing a problem with validating my own product ideas.
I noticed the lack of tools that:
- Let you create waitlist pages fast (always faced complicated page builders)
- Have conversion optimized templates (we have 5 and we’re planning to add more)
- Support custom domains
That’s exactly why I launched FastWaitlist. It has solved a huge pain point for me and I hope it’ll do the same for you.

13. Show HN: Peer-to-peer Collaborative databases in the browser
URL: https://github.com/adhamsalama/sqlite-wasm-webrtc
Author: adhamsalama
Description: I have been trying to run SQLite in the browser using WebAssembly, then I had an idea, why not make it collaborative using WebRTC? This way, you wouldn’t need a centralized server to share data with other people.
When you open the website, a persistent SQLite database will be created. When you join a room with other peers, any SQL statements or file imports by any peer will be replicated to the rest of other peers using WebRTC.
This actually solves a problem I face when I need to share some data to analyze it with other people because we use Google Sheets, but I don’t like analyzing data using spreadsheets, I find SQL to be much better, so this project allows me to leverage the full power of SQL(ite) and also be able to collaborate with other people.

16. Show HN: Every Possible AWS Policy Operator with Examples
URL: https://iam.cloudcopilot.io/resources/operators
Author: davidjkerber
Description: AWS Policies have 27 operators like StringEqual, or ArnLike. You can also add set operators (ForAllValues or ForAnyValue) at the beginning of all of them and IfExists at the end. They way these modifiers interact and and behave isn’t well documented; I’ve noticed even experienced AWS engineers have trouble remembering all the nuance. So I documented every possible combination (159) and created examples of how they behave in Allow and Deny statements.
I hope you find it useful and would appreciate any feedback.

URL: https://www.harysdalvi.com/classics-converter
Author: crackalamoo
Description: This is a website that converts Latin/Sanskrit to modern Romance/Indian languages. The catch is, rather than a translation, it is purely based on deterministic phonological algorithms. Since linguists have determined fairly regular rules for these transformations, I thought why not code these rules into a computer?
While the result isn’t perfect, it often works pretty well, and the cases where it fails sometimes give some insight into why a language evolved the way that it did.

20. Show HN: Bookface for Non-YC Founders
Author: ednevsky
Description: Excited to announce my new project, Rally! It’s a useful community for early-stage startup founders, inspired by Y Combinator’s Bookface.
Site: https://rally.socap.ai/
We think many problems that founders have can be solved 10x better through other founders, but there’s no tool/place to do that well and at scale.
For example, instead of googling how to launch on PH, reading blog posts, etc., you could ask for an intro to a famous hunter who’ll explain all that and hunt your product.
We’re building this place + software to make it work really well.
What Rally is:
• A network of highly-vetted founders; many are YC alums • Bookface-like forum for structured discussion • Chat for quick qs / asks • Searchable forum archives • Searchable and detailed founder profiles
What you can use it for:
1. Getting warm intros for fundraising, sales, hiring, etc. 2. Getting individualized, comprehensive advice on all things startups, from cloud providers to burnout to PMF 3. Solving problems of all kinds, from your app being banned at the app store to getting a $XXk cloud provider bill 4. (Optional) Talking to other early-stage founders once a week during our office hours
We think it’ll work because of highly-vetted members, self-selection by our thesis, and thorough moderation.
Like YC, we’re also looking for ambitious founders working on interesting things that grow very fast. But, in addition to that, we only recruit founders who believe what we believe: that many problems they face daily can in fact be solved through other founders, that there’s no great tools that help with this, and that it’d be cool to have one.
If you’re interested, you should try it out! Rally costs $49/month with a refund if you don’t find it useful.
Apply here: https://ywreftjvygn.typeform.com/to/vpekITsX
Our process consists of an application and a Zoom interview. We’re planning to accept 30 founders in Oct-Nov to get things going, and then open up for more applications.
Join the Rally!

26. Show HN: I made a lightweight data visualization platform
URL: https://app.prettydata.xyz
Author: gojam
Description: Hey everyone,
I’ve been working on a project called PrettyData, a lightweight data visualization platform. My goal is to make it easier for anyone to turn raw data into beautiful dashboards, even without deep technical skills. Just by easily clicking through.
What it does:
- Pulls data directly from Google Sheets, Dune Analytics or Postgres tables.
- Lets users build and customize dashboards easily with ECharts
- No-code and just with
I started this because I noticed there are free tools as Superset, but the learning curve is a bit steeper and probably too complicated for most not deeply technical people. PrettyData aims to be the missing link between semi-raw data and useful dashboards—without friction.
Why it might interest you:
- 14 day free trial, no credit card required.
- I’d love to hear feedback from the HN community on the concept, user experience, or areas for improvement.
- Feature requests are welcome — I’m balancing development and marketing, so your input would help steer things in the right direction.
If this sounds like something you’d find useful, I’d appreciate it if you gave it a spin at https://app.prettydata.xyz. Your feedback would mean a lot and help shape the product!
Thanks for reading, and feel free to AMA in the comments.

28. Show HN: SpanishDict Shortcuts (Chrome Extension)
URL: https://chromewebstore.google.com/detail/spanishdict-shortcuts/kaofhiepffpamofkjebbigaikmhdbjld
Author: SomeWan
Description: Hey Hacker News,
some of you might be familiar with spanishdict.com - a fantastic website to learn Spanish for free. As a regular user of the site, I was missing some features that would elevate the learning experience to the next level.
So I developed SpanishDict Shortcuts, a small Chrome browser extension that makes learning on spanishdict.com more customized to your learning workflow.
It contains features like keyboard shortcuts to toggle subtitles on grammar videos so that you can practice your listening comprehension for example. Or editing the navigation bar to show the most relevant links to you. As well as changing the replay speed of videos, replaying a video on shortcut and many more quality of life features.
Looking forward to your feedback!
P.S.: The extension can be installed but is only available via link for now. This is because I want to test it before making it public.

URL: https://blueskyvideodownloader.org/
Author: yangxiaobo
Description: Hey HN,
Recently, a friend introduced me to the Bluesky platform, and I found it intriguing—especially its focus on decentralization. I believe it has the potential to become the next Twitter, and it already has over 13 million users.
Today, as I was browsing the platform, I came across a video in one of the posts that I found really interesting and wanted to download to my local drive. However, after searching for a while, I couldn’t find a suitable tool for this purpose.
So, I thought, why not create a tool to meet this need? All it should require is the link to a post, and it would allow users to download the embedded video directly to their local storage.
With Cursor’s help, I managed to complete this tool in just one day. It’s now fully functional and can download videos from Bluesky posts.
I’m thrilled to share this tool with everyone, and I hope you find it useful.
would love your feedback pls

Rating my mental health in an awful Excel sheet sucked and nobody wanted to do it.
So I created this project to avoid the meaningless 1-5 rating and instead share emojis, gifs or text.
No more boring ratings.
I hope this will make your weekly (or daily) mood check more exciting.

37. Show HN: Globset for Nix Source Filtering
URL: https://github.com/pdtpartners/globset
Author: hinshun
Description: Hi there! I am Edgar and I wanted to share with you “globset”, a Nix library to help specify what sources to include when building a Nix package using familiar glob patterns like “/.go”.
Nix is package manager and meta build system, in that you glue together compilers and other build systems in repeatable sandboxes like “docker build”. When specifying the source inputs to a Nix package, you typically end up with irrelevant files that when changed causes a rebuild unnecessarily.
“globset” provides a concise and simple way of specifying what sources should be included. It is built on top of the new “fileset” library introduced in Nixpkgs 23.11, and is composable with any libraries using it. This is our second open source project after releasing nix-snapshotter last year. (See: https://news.ycombinator.com/item?id=37407758)

42. Show HN: Block Blast – an addictive block puzzle game
Author: Zephyrion
Description: Absolutely thrilled to see Block Blast launch here! As a fan of puzzle games that actually make you think, I’ve got to say, Block Blast is a breath of fresh air. The strategic placement of blocks on an 8x8 grid adds a layer of depth that’s often missing in other puzzle games. I love how it challenges you to plan ahead and think critically with each move.
What really stands out for me is the innovative combo system – clearing multiple lines at once is not just satisfying, it’s outright thrilling with those elimination animations. Plus, the diverse levels ensure that you’re always on your toes, adapting strategies and keeping the gameplay exhilarating.
And let’s talk about the visuals and sound effects – they’re top-notch, creating an immersive experience that’s hard to put down. The fact that there are no time limits is a massive plus for me; it’s a game that respects your time and lets you enjoy the challenge at your own pace. Whether you’re a casual gamer or a puzzle enthusiast, Block Blast is definitely worth a try. Can’t wait to see what the community thinks! Give it a spin and join the discussion – let’s talk blocks!
