Show HN: YouTube Summaries Using GPT
Hi, I'm Alex. I created Eightify to take my mind off things during a weekend, but I was surprised that my friends were genuinely interested in it. I kept going, and now it's been nine weeks since I started.<p>I got the idea to summarize videos when my friend sent me a lengthy video again. This happens to me often; the video title is so enticing, and then it turns out to be nothing. I had been working with GPT for 6 months by the time, so everything looked like a nail to me.<p>It's a Chrome extension, and I'm offering 5 free tries for videos under an hour. After that, you have to buy a package. I'm not making money yet, but it pays for GPT, which can be pricey for long texts. And some of Lex Fridman's podcasts are incredibly long.<p>I'm one of those overly optimistic people when it comes to GPT. So many people tell me, "Oh, it doesn't solve this problem yet; let's wait for GPT-4". The real issue is that their prompts are usually inadequate, and it takes you anywhere from two days to two weeks to make it work. Testing and debugging, preferably with automated tests. I believe you can solve many problems with GPT-3 already.<p>I would love to answer any questions you have about the product and GPT in general. I've invested at least 500 hours into prompt engineering. And I enjoy watching other people's prompts too!

Show HN: Don't lose track of HN post comments
Yesterday, I got lost track of the HN post comments.<p>I fixed that problem → http://hntoast.com<p>I make this in the last couple of hours. So, if you have any feature requests or feedback.<p>Let me know your thought about this tool.

Show HN: Doc Converter – Convert PDF docs to Word documents on your computer
Show HN: 1Kb Webspace
Hey guys, I wanted to introduce you my hacknight project.<p>It is a tribute to onekb.net which has stopped its service a few years ago. Currently it is still a beta where external resources are also possible (but not the point ;) ) to get your opinions.<p>When it is finished, the source code will be open source. The secret word is therefore also hackernews.<p>P.S.: The source code is currently 2.4Kb I'm trying to make it smaller. 1Kb would be my goal.

Show HN: I'm a doctor and made a responsive breathing app for stress and anxiety
Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (<a href="https://www.pi-a.io" rel="nofollow">https://www.pi-a.io</a>) which developed Lungy (<a href="https://www.lungy.app" rel="nofollow">https://www.lungy.app</a>). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU.<p>My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were huge numbers of patients coming off ventilators and they are often given breathing exercises on a worksheet and disposable plastic devices called incentive spirometers to encourage deep breathing. This is intended to prevent chest infections and strengthen breathing muscles that have weakened. I noticed often the incentive spirometer would sit by the bedside, whilst the patient would be on their phone – this was the spark that lead to Lungy!<p>The visuals are mostly built using Metal, with one or two using SpriteKit. There are 20 to choose from, including boids, cloth sims, fluid sims, a hacky DLA implementation, rigid body + soft body sims. The audio uses AudioKit with a polyphonic synth and a sequencer plays generated notes from a chosen scale (you can mess around with the sequencer and synth in Settings/Create Music).<p>There are obviously lots of breathing and meditation apps out there, I wanted Lungy to be different - it's about tuning into your surroundings and noticing the world around you, so all the visuals are nature-inspired or have some reference to the physical world. I didn’t like other apps required large downloads and/or a wifi connection, so Lungy’s download size is very small (<50MB), with no geometry, video or audio files.<p>Lungy is initially a wellness app, but I’d like to develop a medical device version for patients with breathing problems such as asthma, chronic obstructive pulmonary disease (COPD) & long COVID. Thanks for reading - would love to hear feedback!

Show HN: Signal-Android – A fork of Signal that provides SMS support
Signal was a brilliant app. It can send messages with rich media, host group chats, and even do voice and video calls, all with the peace of mind that comes from a proper secure messaging app. The best part was that you could still send messages to people who don't use Signal. Signal was the messaging app everyone wants - all the benefits of iMessage, without being siloed in one particular ecosystem.<p>Sometime leading up to October of 2022, the folks at the Signal foundation lost the plot. Signal has since dropped support for SMS, and is inexplicably adding "stories" to their personal messaging app. I despise this.<p>Instead of just complaining about it, I decided to do something about it. Here is a link to a version of the Signal Android app that still supports SMS, and doesn't have stories. There also isn't a stupid, nagging banner telling you to update. Right now, it's just Signal 5.38 with a couple lines commented out, but I plan to integrate any upstream security/UX improvements in the near future. For now, you'll have to build/install it yourself, but I will eventually put an APK out there for people to download. Enjoy!

Show HN: Automatisch – Open source workflow automation, an alternative to Zapier
Hey, HN community,<p>We're so excited to share Automatisch with HN finally. Automatisch is an open-source workflow automation tool, an alternative to Zapier. Together with my co-founder (@barinali), we have been working on it for about 15 months and have started getting early adopters.<p>Automatisch is a workflow automation tool that lets you connect different web services like Slack, Github, Twitter, and more to automate your business processes. For example, you can build automation that gets all new tweets, including the "open source" phrase, and post them to the Slack channel you specified. You can adjust the services and steps depending on what you actually need to automate in your business.<p>Even though some existing cloud solutions do the job well enough, we still wanted to build an open-source and self-hosted alternative to those. Because it allows you to store your data on your own servers, which is essential for businesses that handle sensitive user information and cannot risk sharing it with external cloud services. This is especially relevant for industries such as healthcare and finance, as well as for European companies that must comply with the General Data Protection Regulation (GDPR).<p>You can see the available integrations here (<a href="https://automatisch.io/docs/guide/available-apps" rel="nofollow">https://automatisch.io/docs/guide/available-apps</a>). We currently have limited integrations but are constantly working on adding more and enhancing the existing ones.
