Show HN: I built a non-linear UI for ChatGPT

Hi HN,<p>I built this out of frustration of the evergrowing list of AI models and features to try and to fit my workflow.<p>The visual approach clicks for me so i went with it, it provides more freedom and control of the outcome, because predictable results and increased productivity is what I’m after when using conversational AI.<p>The app is packed with features, my most used are prompt library, voice input and text search, narration is useful too.<p>The app is local-first and works right in the browser, no sign up needed and it's absolutely free to try.<p>BYOAK – bring your own API Keys.<p>Let me know what you think, any feedback is appreciated!

Show HN: I built a Notion for science

I struggle with handwritten notes, but it's always been the primary way to write scientific notes. To do scientific writing on existing keyboard-and-mouse tools generally requires either significant knowledge of the software, the use of screenshotting/exporting from external tools, or (often) both.<p>That's why I made Stempad, which is meant to rival the speed of pen-and-paper for scientific writing. I've currently added 7 different scientific blocks (and several basic blocks too) and plan to continuously add more.<p>Questions are welcome, and preliminary feedback or constructive criticism is really appreciated!<p>(If you're on mobile or would prefer to see a demo, here is one: <a href="https://www.youtube.com/watch?v=U-9j8sFIkS4" rel="nofollow">https://www.youtube.com/watch?v=U-9j8sFIkS4</a>)

Show HN: I made a text to website generator powered by gpt4 and tailwind

Hello HN! A few weeks ago I tried looking for a way to quickly create business sites without spending hours designing or using generic templates. AI seemed to be the answer. After trying multiple AI builders I couldn't find one that was easy to use and didn't use templates. I wanted something truly dynamic a tool that can create a website for anything fully AI driven design decisions based on my description. So I created one. A truly dynamic AI web builder.(Powered by GPT4 with styling done in tailwind css). Try it out here <a href="https://www.instawebai.com" rel="nofollow">https://www.instawebai.com</a>

Show HN: Skyrim – Open-source Large Weather Model (LWM) Zoo

Hi HN, I'm Efe from Secondlaw AI. We are building physics-informed large AI models. Currently, we are focusing on weather modelling.<p>To benchmark SOTA, we had to build a forecasting infra for all available large weather models and we could not find a solid tooling to do so, so we built Skyrim. Within <5 mins and <5 LOC you can run forecasts on par with global weather models that are run on 100K+ CPU HPCs!<p>We are implementing more models & fine-tuning capabilities. Let us know if anything more we can add, also happy to answer any questions!

Show HN: Visual debugger for Rails system tests

Hey all, I've been working on this side project to get a Cypress.io-like experience, but for Ruby developers. It's plug-n-play with Capybara system tests, with the following features: - visualize assertions/commands as they happen - view all API requests, errors, and logs in the timeline - pause/continue on any step - rewind through history with a recorded video<p>This is brand new, so looking for people to start trying it out and leave feedback.

Hi HN! Touvlo is a platform where you can delegate your technical interviewing for hardware engineers to us, so that you can focus on building your product instead.<p>Our interviews test real-world engineering skills, largely via a collaborative CAD session through our in-browser platform. You can think of it as a pair-coding session between the interviewer and the interviewee, but for hardware. Interviews are conducted by real hardware engineers with industry experience (currently my co-founder, Danae). After each interview, you get a detailed score card, as well as full, timestamped recording of the interview.<p>There's no pricing page yet, but we charge 220$ per interview, with discounts for monthly packages for 10 interviews or more.<p>If you're a hardware/robotics startup, give us a try: we can help you hire better and save you time. Drop us an email (founders@touvlo.co), or sign up for a demo interview on <a href="https://touvlo.co" rel="nofollow">https://touvlo.co</a>. We offer a money-back guarantee and a free trial for our next few customers.<p>We're also applying to YC – we went from an idea to a product with users in 2 months.<p>We would highly appreciate any feedback.

Show HN: Peerdb Streams – Simple, native Postgres change data capture

Hello HN, I am Sai Srirampur, one of the Co-founders of PeerDB. (<a href="https://github.com/PeerDB-io/peerdb">https://github.com/PeerDB-io/peerdb</a>). We spent the past 7 months building a solid experience to replicate data from Postgres to data warehouses. Now we're expanding to queues.<p>PeerDB Streams provides a simple and native way to replicate changes as they happen in Postgres to Queues (Kafka, Redpanda, Google PubSub, etc). We use Postgres logical decoding to enable Change Data Capture (CDC).<p>Blog post here: <a href="https://blog.peerdb.io/peerdb-streams-simple-native-postgres-change-data-capture">https://blog.peerdb.io/peerdb-streams-simple-native-postgres...</a>. 10-min quickstart here: <a href="https://docs.peerdb.io/quickstart/streams-quickstart">https://docs.peerdb.io/quickstart/streams-quickstart</a>.<p>We chose queues as many users found that existing tools are complex. Debezium is the most used tool for this use-case. It has large production usage. However, a common pain point among our users is that it has a significant learning curve taking months to productionize.<p>A few issues are: a) Interacting through a command line interface, understanding the various settings, and learning best practices for running it in production is not trivial. Debezium UI, released to address usability concerns [1], is still in an incubating state [2]. Additionally, reading Debezium resources to get started can be overwhelming [3]. b) Supporting data formats and transformations isn’t easy. It needs a Java project, building JAR packages and setting up a runtime path on the kafka connect plugin. c)Debezium is not as native as Kafka for other queues and doesn’t offer the same level of configurability. For example, with Event Hubs, it is difficult to stream to topics spread across namespaces and subscriptions.<p>TL;DR Debezium aims to provide a comprehensive experience for engineers to implement CDC rather than making it dead simple for them. So you can do a lot with Debezium but need to know a lot about it.<p>At PeerDB, we are building a simple yet comprehensive experience for Postgres CDC. The goal is to enable engineers to build prod-grade Postgres CDC with a minimal learning curve, within a few days.<p>PeerDB’s feature-set isn't at Debezium's level yet, and as we evolve, we might face similar challenges. However, we're putting usability at the forefront and we believe that we can achieve the above goal.<p>First, PeerDB offers a simple UI to set up Postgres and Kafka by creating PEERs and initiating CDC by creating a MIRROR. Through the UI, users can monitor the progress of CDC, including throughput and latency; set up alerts to Slack/Email based on replication slot growth; investigate Postgres-native metrics, including slot size, etc. Here is a demo showing of PeerDB UI in action:<p><a href="https://www.loom.com/share/ebcfb7646a1e48738835853b760e5d04" rel="nofollow">https://www.loom.com/share/ebcfb7646a1e48738835853b760e5d04</a><p>Second, for users who prefer a CLI, we provide a Postgres-compatible SQL layer to manage CDC. This offers the same level of features as the UI and is more intuitive compared to bash scripts.<p>Third, users can perform row-level transformations using Lua scripts executed at runtime. This enables features such as encrypting/masking PII data, supporting various data formats (JSON, MsgPack, Protobuf, etc.), and more. We offer a script editor along with a bunch of useful templates [5].<p>Fourth, we provide native connectors to non-Kafka targets. We also provide native configurability options tailored to these platforms. For example, with Event Hubs, users can perform CDC to topics distributed across different namespaces and subscriptions [4].<p>Finally, We are laser focused on Postgres, enabling specific optimizations like native metrics for replication, wait-events, and # of connections. Features like faster initial loads through parallel snapshotting and decoding transactions in-flight are in private beta.<p>Our hope is to provide the best data-movement experience for Postgres. PeerDB Streams is another step in that direction. We would love to get your feedback on product experience, our thesis and anything else that comes to your mind. It would be super useful for us.
