2. Show HN: Pure CSS silky Border line animation(open-source code)
URL: https://github.com/volume988/button-motion
Author: volume988
Description: Use only CSS to achieve a silky border line animation effect. Key implementation ideas include:
1. Perspective effect: Create a border effect by setting up two nested elements with the parent element having 1 pixel padding.
2. animation: Create an absolutely positioned child element and use the animation property to move it uniformly along the border of the parent element.
3. Uniform animation: By calculating the path and distance of the element movement, adjust the percentage of key frames to ensure uniform animation.
4. Rounded corners: Add rounded corners to the parent and child elements, and adjust the position of the animation elements to fit the rounded corners.
5. Animation optimization: Adjust the animation trajectory at the rounded corners to ensure a natural and smooth transition.
6. Blur shadow: Achieve the shadow effect by setting the background radial gradient of the child element and using the backdrop-filter attribute to add a blur effect.

3. Show HN: Questdown.de – make paper-based questionnaire with Markdown-ish syntax
Author: kakalot
Description: Hey, I’ve been working on a project built on top of markdown python for the last few weeks. It is still very much a work in progress, but I think it is at a place where it could start to be useful.
Per the rule, it's functional to try out the syntaxes, but convert to pdf I still put behind an registration to avoid getting my server killed :)
Feedback and contributions are more than welcome!

5. Show HN: ConvexValue – Financial Analytics Browser
Author: jbtobar
Description: I built a Financial Analytics Browser. It is like a web-browser, but instead of browsing the internet you browse a curated selection of financial analytics "modules". "Modules" are self-contained tools designed to be to-the-point, light, and without ads. In the case that modules require data license payments, you can manage it all within one place.
It also features split-pane dashboards, so you can create, edit, share, clone dashboards with these modules.

6. Show HN: Fin.flights 2.0 – AI-powered flight search
Author: truly_sn
Description: fin.flights is an AI-powered flight search tool that uses natural language processing to find the best flights based on user queries. just released version 2.0 with significant improvements:
- No login required: Start searching immediately without creating an account
- Advanced AI: Utilizing latest LLMs for more accurate flight results
- Natural language interface: Type queries as you would ask a friend
- Global coverage: Searches flights worldwide with multi-language support
- Free to use: Only upgrade if you find it valuable
How it works:
- Enter a natural language query (e.g., "cheapest business class flights from NYC to Tokyo in the next 3 months with max 1 stopover")
- Our AI interprets the query and searches across multiple airlines and booking platforms
- Results are displayed instantly, sortable by price, duration, or best value
I built this because existing flight search engines often require too many inputs and don't offer the flexibility of natural language queries. Myy goal is to make flight search as simple as asking a knowledgeable friend.
I'd love to get feedback from the HN community on the user experience, AI accuracy, and any features you'd like to see added.

9. Show HN: Fast Music Remover – Remove Music and Noise from Internet Media
URL: https://github.com/omeryusufyagci/fast-music-remover
Author: omeryusufyagci
Description: I've recently open-sourced a tool for removing music, sound effects, and noise from internet media, with an emphasis on speed and simplicity. The project processes videos at around 8% of the original media length — meaning it can handle a 10-minute video in under a minute.
Repo: https://github.com/omeryusufyagci/fast-music-remover
The tool is lightweight, works through Docker, and is licensed under MIT. It supports several use cases, such as improving the audio quality of lectures, field reports, and isolating speech from videos with heavy background noise.
I'm currently working towards adding live stream support and would love to have contributors on board. There are interesting open issues for developers experienced in backend, frontend, Python, C++, and audio processing.
Feedback, suggestions, and contributions are very welcome. Thanks for checking it out!

15. Show HN: Betternews, a mobile HN client to have 1-on-1 coffee chat with HN users
URL: #
Author: canergly
Description: Hi, I have published a mobile app to have coffee chat with HN users.
There was already a guy who made a website for this, but I wanted to do it in mobile to practice WebRTC(technology behind the audio chat) and have some fun.
I haven't spent too much time in terms of the general functionality as a HN client but can upgrade it if there are enough users enjoying the app.
You can download the apps via the links below;
IOS: https://apps.apple.com/tr/app/betternews-coffee-chat/id65047...
Android: As you might have known, Android requires the app to be tested in a closed beta with at least 20 people So you can follow these steps to be a part of it and download;
1 - join the group https://groups.google.com/g/betternews
2 - download the app and enjoy https://play.google.com/store/apps/details?id=com.apps.bette... or https://play.google.com/apps/testing/com.apps.betternews

16. Show HN: Unlearn Stress – A Stress Reduction App with Personal Voice Narration
URL: https://www.excsn.com/apps/unlearn_stress
Author: excsn
Description: I made it for me as I’ve been having episodes with stress with no specific origin. Been to doctors with some luck from one hopefully the recent operation will address another potential issue. Some days I feel down, out of it, just lack of energy and expression and I don’t know why exactly, but hearing some of the stories, even when I’ve heard them before, help with getting out of a slump.
I found that the 'Shaman' breathing exercise (humming “ohmmmmm” on exhale) for 15-30m, on wakeup and before sleep, has been the most helpful for me. Takes about 10m of doing it for my body to really relax my muscles.
I also found being read stories, that are inspired by the things I knew growing up things I know now, things I wish I knew as a kid, tv shows, friends, current events, forums and etc., are very helpful with my own mindset. Everyone's in a different position and being reminded of perspective can be highly motivating. Narration with your own personal voice is fun (Android needs to catch up!). Wish I could have my voice recorded as a child reading some of these ha!
What ‘Unlearn Stress’ offers:
- Guided Breathing Exercises: Quick and easy breathing exercises that you can do anytime, anywhere to help promote relaxation, reduce stress and refocus.
- 100+ Relatable Short Stories: Stories about work, burnout, life, relationships, uncertainty that hit home, like one about a world taken down by a bug ;), inspired by the recent CrowdStrike outage, inventing things but getting no traction or the constant chase for social media popularity. It’s all about finding some calm in the chaos.
- Personal Voice Narration (iOS 17+): For iPhone 12+ users, you can have stories narrated in your own voice, making the experience feel super personal. (https://support.apple.com/en-us/104993)
- Educational Resources: Simple tips and insights to help you manage stress better every day.
The app works completely offline and there’s no Data Collection like other apps. There’s a lifetime premium version for $4.99 which is budget friendly. Tired of subscription services and unnecessary data collection, I'm stuck in the 90s mindset I guess.
You can add also more voices on device for story narration
- iPhone: Accessibility > Spoken Content > Voices. Click on a voice and check if enhanced version is available.
- Android: https://support.google.com/accessibility/android/answer/6006...
Where to find it:
- iOS App Store: https://apps.apple.com/us/app/unlearn-stress-with-stories/id...
- Google Play: https://play.google.com/store/apps/details?id=com.excsn.andr...
I hope it helps you as much as it has helped me. Would love to hear your thoughts and suggestions you might have!
Thanks for checking it out!

URL: https://chatone.io
Author: BeeFriedman
Description: Hi HN,
I built ChatOne while working on a project and constantly switching between AI models like GPT-4 and newer ones like Claude 3.5. I kept wondering if I was missing out on better answers, so I created ChatOne to get responses from multiple models at once and compare them easily.

URL: https://64.surf/
Author: burcs
Description: Hey HN,
I built this to scratch an itch I had around what can be done solely using the URL.
It's very minimal with no storage involved, and your files can even be encrypted. The only caveat is some platforms wont allow you to post long links. I thought about using a URL shortener, but storing and mapping URLs kind of defeats the purpose.
However most browsers do allow you to open them once you have them. For instance I was able to "share" a 10MB file using safari, however 350KB seems to be the max for Chrome.

24. Show HN: I was tired of writing HTML emails so I built something that works
Author: Utkarshn10
Description: Hey HN,
I was tired of writing HTML emails and one day was going through reddit specifically searching for people who hated writing HTML emails and heard a lot of complaints from solopreneurs and marketers as this is a very boring task and many marketers and solo founders have much more important tasks to take care off.
So I decided to build HTML email to solve this. My friends have already saved hours using this product.
This is my 11th product and I think this solves a problem many folks are struggling with. Feel free to share your views.

Author: molotochok
Description: On my job I needed to see the content of Outlook .msg file. You might assume that, I could simply open it in Outlook app. It might have worked on Windows, but not on Mac. As there it expects .eml instead of .msg. I also didn't want to use any website that in order to parse the file uploads it to an external server. It is insecure and violates the company policy as the internal data can be exposed. So, I decided to create a simple .msg viewer that doesn't send any request to an external server and reads the file in browser. It is extremely fast and safe as the data is not shared with third parties.

It implements Flux principles using an object-oriented approach.

33. Show HN: Model2Vec: make sentence transformers 500x faster on CPU, 15x smaller
URL: https://github.com/MinishLab/model2vec
Author: stephantul
Description: Hi HN!
We (Thomas and Stéphan, hello!) recently released Model2Vec, a Python library for distilling any sentence transformer into a small set of static embeddings. This makes inference with such a model up to 500x faster, and reduces model size by a factor of 15 (7.5M params or 15/30MB on disk, depending on whether you use float16 or float32). This allows you to embed 50-100k documents per second on a cpu on a macbook.
This reduction of course comes at a cost: distilled models are worse than their parent models. Even so, they are actually a lot better than large sets of conventional static embeddings, such as GLoVe or word2vec-based models, which are many times larger. In addition, the performance gap between a Model2Vec model and a sentence-transformer ends up being smaller than you would expect, see: https://github.com/MinishLab/model2vec/tree/main?tab=readme-... for results. Fitting a Model2Vec does not require any data, just a sentence transformer and, possibly, a frequency-sorted vocabulary, making it an easy solution to implement in whatever workflow you have lying around.
We wrote this library because we separately got a bit frustrated with the lack of options if you need extremely fast CPU inference that still works well. If MiniLM isn’t fast enough and you don’t have access to a GPU, you’re often resigned to using BPemb, which is not flexible, or training your own GLoVe/word2vec models, which requires lots of data. Model2Vec solves all of these problems, and works better than specialized static embeddings trained on huge corpora. We spent a lot of time thinking about how the library could be easy to use and integrate into common workflows.
Besides tight integration with huggingface, we also have an upcoming sentence transformers integration, releasing this week. This will allow you to directly integrate and distill model2vec models in whatever libraries support sentence transformers. This means out of the box support for llama-index, scikit-learn via embetter, langchain, and many other frameworks.
Please let us know what you think. We’re very interested in getting feedback from you. We’re already using this in our own projects, and ultimately built this because we kind of needed it, but we’d be happy to hear from you if you have interesting use-cases or questions.
Have a nice day!

34. Show HN: BootstrAPP.xyz – A self-bootstrapping platform for app idea validation
Author: axzilla
Description: I'm building an app development platform that bootstraps itself. The twist: we're using the same process to build it that developers will use to validate their own app ideas.
Key concept:
- The platform starts as a simple idea submission and voting system.
- Developers (you) suggest features for the platform itself.
- The community votes on these features.
- I implement the most popular features.
- As the platform evolves, developers can use it to validate and develop their own app ideas using the same process.
Tech stack:
- Backend: Go
- Frontend: HTMX + Alpine.js
- Templating: Templ
- Approach: MPA with server-side rendering
- Deployment: Single binary file
Current state: A text box for submitting feature ideas and a voting system.
Goal: Create a meta-platform where the process of building the tool becomes the tool itself. You shape the platform now, then use it to shape your own apps later.
Questions for HN:
- What features would you want in an app idea validation platform?
- How meta can we get? Any ideas for features that are both useful for the platform and for future apps built on it?
Check it out at https://bootstrapp.xyz and help bootstrap a tool that you'll use to bootstrap your own apps!
